For many years, nickel-cadmium had been the only suitable battery for portable equipment from wireless communications to mobile computing. Nickel-metal-hydride and lithium-ion emerged In the early 1990s, fighting nose-to-nose to gain customer's acceptance. Today, lithium-ion is the fastest growing and most promising battery chemistry.

li ion battery in 12 v/400 ah
The search for a battery to power our electric cars should include an all liquid battery. Instead of having to charge the battery at home or at a charging station, I think a better idea would be to have a storage system where the liquid battery would be stored in the car untill the charge is spent and then like going to the gas station you would pump out the spent liiquid battery and put in a charged liquid battery. Instead of having to wait until the battery is charged(like the present situation) you would just wait until the battery(liquid) is exhanged. Another option would be to exchange a spent physical battery for unspent one. What do you think?
My comment is. If there is a big market for this product.
Very much interested if finding out the potential to commercialize this particular Battery
of lithium in global proportion
What is the mechanism that causes some types of Lithium batteries to violently
explode ?
What are the statistics of thses Lithium batterie exploding ?
would 1 per thousand be correct ?
LiON battery would explode if the reaction create some hidrogen and in the expansion two contact give a short circuit. If the battery was made by low quality processes the percentage can be higher, but in normal circumstances, precaution like described in this article, the percentage is better: one on millions of units.
I just got a lithium ion battery powered Dyson vacumn. From what I understand you are saying, it's best to prolong its life by 1) not fully charging it each time - only charging it to about 80% of full capacity and 2) storing it at 40% charge in a cool place when not in use. Is there any other practical advice?
thank you for your articles.
Why do Lithium_ion_batteries have three electrical contacts, i.e. + (plus), -(minus) and an unmarked one? Is the latter conected to the charging (safety) circuit?
It is not clear to me the sentence "The maximum charge and discharge current on most packs are is limited to between 1C and 2C". "1C and 2C" should be "1A and 2A" (amps), since it refers to a current?
The C rating of a battery is its discharge rate (or it can also represent a charge rate). It is defined as the amount of current it can safely discharge over a period of time expressed in multiples of the batteries total rated capacity. A battery's C rating is equivalent to it's mah rating sustained for one hour. For example a 3000 mah battery being discharged at 1C, or 3000ma, will last one hour at that discharge rate, this equals 1C… At 0.5C (1500ma) it will last for 2 hours. That same battery being discharged at 2C (6000ma) would last 30 minutes, etc. The same principle applies to charge rates as well. Different technologies can handle different rates.
I would like to know if more research is done into other tehnologies (non-lithium) because this element (Lithium) is in low quantities on Earth thus beeing unwise to over-develop something based on a rare material (just a very few countries have lithium reserves). When I think what will be to replace all present petrol/diesel cars just from one developed country with lithium based energy storage will requiure more than we can find on entire planet.
An ideal battery… questionable, for the moment in small apliances yes, in next 30-40 years of course not.
I am concerned about the weather. Will freezing affect the Lithium-Ion battery on my Travel Scooter (wheelchair). I know I have to protect it from the heat. I have a spare battery, but both batteries have been left in the rental car exposed to the cold.
Lithium is not rare, many countries have large reserves.
Freezing should not hurt the battery but it may reduce it's capacity when cold. They should be warmed up some before charging to take more charge.
Thanks JP, I'll be sure to bring my batts to room temp b4 charging & won't put them in the car until just b4 I leave, so they won't be too cold to provide optimum capacity.
BTW, I have a spare because they quit without warning, unlike gel cells which give a fair reading of remaining charge. Is there an affordable & convenient device available that I can use to read the Li-Ion?
Can a Li-ion battery be used in a cordless drill which calls for a NiCd? Are they interchangeable?
Ross: thats a big NO! The drill may work with a Li-ion battery if it fits, chances are it wont. But you cannot use a NiCd charger with a Li-ion battery. Lithium batteries are very sensitive and need specific chargers to control the amount of current etc.
If your drill is NiCd i suggest you stick to NiCd or NiMh batteries. And if you really want a Li-ion battery for whateva reason, go buy a Li-ion drill.
I am having problems with a 12 volt Li-ion drill & saw. Especially in colder weather the batteries just shut down - the battery overload protection just cuts in. I get this problem with the smaller 1,5 Ah batteries but not with the 3ah ones. Could the batteries of been damaged by being kept cold - they live in my van so could be -5 at night ?. Or could the batteries have developed a fault.
Many tool shops are warning against Li-ion & are reporting lots of problems.
Thank you for your reply BWMichael. But after further research, the answer is at least partially 'yes.' Perhaps my question should have been better stated as to 'physically' interchangeable. I understand that they require different chargers - and that is very important! I spoke with a DeWalt representative, who told me that the Li-ion and NiCd batteries were physically interchangeable on their cordless tools. And in fact, Porter-Cable makes a line of 'bare tools', which are sold without a battery - allowing the user to choose either NiCd or Li-ion. Thanks again for your input!
I would like to remove NiCd bateries out of my 18v pack and replace with Li-ion,
and use the same charger that came with the NiCd. Is this possible We have problems with the NiCd bateries constantly. I have rebuilt NiCd packs before with NiCd batteries.
Hi Andy - NO you CANNOT charge a Li-ion battery in a NiCd charger. Each type requires a very specific charger, and it would be dangerous to attempt to do so.
Using batteries for SMALL Data Centers – what is next ?
Question: Do you know if APC - American Power Conversion, Eaton Products or the like have or are planning to have Lithium battery based UPS units - Uninterruptable Power Supplies. APC has the Symmetra system this unit uses "Lead acid" based batteries. This unit keeps Data Centers running during power outages in our client sites. Will Lithium be more effective than APC's current batteries - perhaps price would be too high for the market? Any ideas?
As the Global Warming effects start to appear in our state… keeping small Data Centers up and running for 24-hours and in some cases 48-hours electrical outages is critical - wee need better technology!
Yes I know about standby electrical fuel/ gas generators… but for some reason (political) this is not a solution.

I have a Makita cordless driver/drill that I use daily in my trade and, living in Iowa, it can be less than 10 degrees F on a regular basis in winter. What is the effect of freezing on the total number of charge/discharge cycles I can expect in the life of my tool?
I am interested in a nominal 24 volt 44 Ah LiFePO4 battery. What weight cost, electronics? ? ?
the life of battery ran in low or high temperature depend on the active material and discharging rate.
I need to replace two 12V 4.5Ah NiCd batteries from a 1993 camera. Camera eats 25w and NiCd were rated to last for 1.25hrs. I bought a 12V 4800mAh Li Ion. It does not output enough power to run the camera longer than 30 or 40 seconds. It still showes 12.3VDC but does not power the cam. What did I not understand?
we can see that the N-Cd battery is discharging at 0.66C as 3.6A(4.5/1.25) current, the rated power of camera is 25w, rated voltage of camera is 12V, only need 2.0A current is enough.that is the confused point i think.
your information is not enough, what kind of battery it is ,what is the model ,what is the amount ,seriese or parallel.
please give us more information.
I think the battery of different kinds can not be crossed used. the rate of discharging curve is different, the inner resistance is different either.
•Li-ion cells are very sensitive to charging characteristics and may explode if mis-handled.
•Strongly suggest that you use the matched Li-Ion battery charger to recharge the battery pack
•Charging temperature: 0 to 45 degrees Celsius
•Discharging temperature: -20 to 60 degrees Celsius
•Storage temperature: -20 to 45
I just purchased a Casio Exilim underwater camera for my vacation. I use it for about an hour and then the camera stopped working. I thought the battery had to be charged but then it still did not work. When I checked it again the lithium battery looked like something leaked out of it and my camera will not work. Can it be that this happens to these types of batteries or can there be something wrong with the camera itself??? Someone please help!!! Thank you!
I suspect that you have a moisture problem !
Hi, i've purchase a not original sony li-ion battery for my camera.
After one minute of use I read this message:"Non-standard battery is used. Use the info LITHIUM battery." and the camera swich off.
The battery is the same in all aspect from the original.
Why does it possible?
Can I do something to remove the message and use it?
Ales: Unfortunately you cannot remove the message and use this battery.
A few companies including Sony and JVC have made their genuine batteries with micro chips inside and the camera is designed to function properly only when the chip is present in the battery.
This is so aftermarket batteries cannot be purchased and you are forced to buy genuine batteries from them which they can charge as much money as they like.

I have a Panasonic ag-bp15p Li Ion camcorder batter that sat in the camera bag for over 8 years. I charged it and it gave me about 18 minutes to video time. I recharged it and it gave me about 3 seconds and about 10 seconds later the camcorder shut down,
Is there nay way to chock the battery back to life as I used to do with NiCads. I am aware of the high voltage and heat protection it has.
I just purchased one on lone. I wonder if I should have been concerned about shelf life.
Thoughts appreciated.
I really don't think that 18650 cells are 650 mm long.
Is there a lithium ion batter that could put out enough wattage (1200 MIn.) to power a hair driyer that wouldn't weigh the same as a small car?
Other than needing to dry hair out in the woods, what is you r application? You might find a heavy duty inverter and sock the wits out of your car engine as it tried to keep up the voltage. I doubt you are going to find any portable cell block to do it.
I should have specified that I want to design a hand-held appliance with a light, durable, long-lasting battery. (And not what you may be thinking. That's been done.)

Looking to replace 4 "AA" batteries with rechargeable ones for use in a lightweight led array. Nicad rechargeable"AA" only put out 1.2v so I would like a "green" alternative - any suggestions?
Like the article states, Sony commercialized the first rechargeable Li-Ion batteries in the 1990s. They had big plans for their portable electronic devices of the time, such as the Walkman, and they recognized a practical battery was necessary to enable volume sales. But lesser known is that Sony acquired this technology from Duracell in theb1980s, after Duracell gave up on it.

How can I identify chemistry of Lithium cells of my e-scooter's battery, taking into account that they're connected in 16S6P configuration, they are cilindrical and they do not have any writing on them?
"lithium is the lightest of all metals," (in the text)
Metals carry a positive charge. Hydrogen carries a positive charge too. So Hydrogen is the lightest of all metals, with an atomic mass of only 1, where Lithium is 3.
Is it available 1.5 v output, AA sized Lithium ion battery?

Just as a passing piece of information on the Li-ion aging, I have a Nokia 3510i which I've had since 2003. The battery is still the original, stays on most of the time and still has a standby time of about a week. As far as my feeble memory goes the battery still performs roughly as new!
Being ignorant of battery properties I assumed that the longevity was a result of the Li-lion technology. The article would appear to suggest the opposite!
How many failure Ni/Cd cells can be replaced per aircraft battery and is there any limit for replacing the failure cells?
my laptop's new Li-ion battery, with an impressive time period of more than two hours, just stopped working. I can not understand why… may be it was over-heated!
What I want to ask is Why it stopped working at once as its cells were pretty good?
and If cells are still good, then can it be repaired?
This may be a manufacturing defect of the battery. We can't repair the battery and the separator (One of the main component of the cell) of cell may be the reason for over-heating. When is it heated? while charging the battery or using the battery?
lithium cell is a battery that i will always recommend because it has helped me a lot,even during the dark days when friends were not there…THANKS TO YOU LITHIUM CELL!!
lithium cell..THE BEST BATTERY I HAVE EVER HAD
In Lithium-cell, The anode is Graphite over copper foil and the cathode is Lithium cobalt oxide and the separator is celgard trilayer material are the main component of the Lithium-ion cell. The electrolyte is lithium phopho hexa fluride (LiPF6). these components hemitically sealed in Aluminium can material.
So I have a Samsung Galaxy S III, my question is… Is there a need for an initial charging? Do I have to drain the battery first before the first charge? How do you optimize the battery life?
There is no need to drain the battery, you can do charging as per the instruction given by the supplier. Need some instruments to do the optimization and It is dangerous without knowing the technique.
I got another new battery and the same happened to it within 16 hours (It stopped working). Both times laptop was very hot (may be because I do not clean often??) and so was the battery. why was the battery so hot?? I'd like to think that system's heat diffused into the battery!! 7% charge was remaining in battery for the 1st time and 34% remaining 2nd time. Both times laptop was working on battery power, and when the batteries stopped working it shut off like a AC computer whose power plug is pulled suddenly. Now both these batteries do not interact with the laptop. the message that appears on battery icon is "plugged in, charging" but no increase or decrease in the charge level. My laptop is HP Compaq 6910p.
What is the real issue? Fault in laptop or just the heat?

Please tell me which battery will be more effective with such specyfications?
6300 mAh, 6-cells, Li-Ion with Intel Core i5-3317U (minus: no Li-Polymer)
6070 mAh, 6-cells, Li-Polymer with Intel Core i5-2467M (minus: worse processor which use more energy)
5440 mAh, 4-cells, Li-Polymer with Intel Core i5-3317U (minus: less mAh)
Bulged Li battery can be servicing so we can not reuse.
General Lithium ion battery charger question.
I have a CV4 professional intelligent digital balance charger, my battery is an 8-cell, 12v lithium ion pack. When I made the purchase from CV4 they told me this was the charger I needed. Problem is, I keep going through batteries in my ATV(four wheeler). When looking into this I find stats about my charger that say "li-ion/Polymer cell count 1~6 series."
My question is, does this seem right for an 8 cell battery? Maybe I don't fully understand the stats on the charger, the rep at CV4 tells me this is the charger I need…. Why am I going through so many batteries?
@ Stefano Monti
Your assumption was the same used in FAA testing environment for the B787 but has been corrected down to two failures in less than 100'000h since! Lethal. They might have to consider switching back to NiCad with an approx. 50kg weight penalty per battery with no more thermal runaway in cells, which cascaded to the other cells and that resulted in the fire and therefore airplanes being grounded for months now.
May i know which is better or durable " 18650 lithium-ion battery" or "Li-Ion Polymer"? what is there advantage/disadvantage between the 2?
Anyone knows about Mean Time to First Failure of Li-ion batteries?

has any new battery technology been discovered?
My golf buggy with a lithium battery was immersed in a creek. Would it be safe to try the battery or is it likely to be irreversibly damaged? Thanks
If it didn't get damaged, it will upon turning on the key!
You must open the cart and inspect (or make inspect) the battery BEFORE turning on the cart.
Post some pictures!
everthing possible in this world ,i am interested polymer based ionic electrolyte in feature lithium ion battery high energy i am central university research fellow all don't fell i will give good solution about lithium ion battery
yours faithfully
Thanks jumpjack. That's not good news because the motor was still going when we got it out. We disconnected it, but then a person who stopped to help turned it on. It went briefly and died. There is still water dripping out of it - 5 days now. Other than that there is no visible damage.
Brushless motors are waterproof.
Batteries usually are not…. but maybe just the electronics was burnt and the battery cells are still ok…
So do you think it will be all right to try when dry?
Having a couple of generations in industrial commercial electrics - motors & controls,
I would suggest that you take it to a professional golf or electric motor service.
While the motor and or battery may not be damaged - or at least minimally - the controls might have been shorted. Many (most of the) times they can be dried out. And, the motor can be megged for wetness at the start. Otherwise, it appears to be guessing with your pocketbook. Even then you might still be guessing, hopefully you will have reputable service people to deal with. Best wishes.
Thank you AIG. I've found a local repairer who is recommended.
Please keep us up to date!
Will do. Thanks for everyone's help.
The golf trolley is working! The recommended repairer said the situation was hopeless, but then the golf pro tried it and it all appears fine. However, there is still a small amount of water coming out of the battery casing and I'm concerned about its safety, so I haven't yet put in on the charger.
Who is a "golf pro"?
why don't you open, or make open, the battery case and dry it?
A golf pro is a golf professional, ie someone who teaches golf and sells golf apparel and equipment. I haven't opened the battery, because it came with dire warnings about doing so.
What's the different between a Nickel Metal Hydride, a Lithium Ion and a Manganese
Cobalt? Which one is the best?
What would be the capacity of Lithium Ion Battery for replacement of 12 volt 7 AH Lead acid battery for solar lantern of 5watt - 12 volt solar module ?
@Garrick: NiMH are older technology and heavier than lithium batteries.
"lithium ion" is generic for several technologies, including Manganese Cobalt, which are present in some recent lithium batteries, but I don't know their performances.
Sometimes by "lithium ion" are referred first-generation lithium batteries (lot of energy, poor safety, Lithium-Cobalt based).
Manganese should allow better safety.
At such low currents there's no much difference between lead and lithium; lithium becomes better at high discharge rates, for example 7 A from a 7 Ah battery (=1C rate).
I don't know the DIScharge rate of your lantern, but 5W/12V means just 0,42 A REcharge for a 7 Ah battery, which means 0.06C.
What you can do is replace the 12V/7Ah lead battery by a lithium battery with same capacity (7Ah) but 3 times lighter, or by a battery of same weight with 3 times the capacity.
In both cases, battery will last longer than lead battery.
Hi, I've been searching high and low just for some expert advice, and I've found your site care of another forum. My question is that I play golf and my golf trolley is powered by a lead acid battery, which is about 5 years old now, and slowing down, I would like to get it replaced, but not sure whether to go for a lead acid one, or a lithium one, I've read at how lighter they are, but I need an experts reasoning, part from cost, why I would go for lithium over the lead acid. Thank you very much in advance for your help.
I don't think it is worth the effort of switching to lithium for a golf cart: main advantage of lithium is low weight, which allows better performance in acceleration and on slopes; it also allows wider range.
I don't think a golf cart actually needs such improvements.
And a lithium battery costs 3 or 4 times a lead battery!
But if you want to experiment, look for TMF lead batteries or TPPL lead batteries: the first should be cheap and lightweight, the second expensive but they will last longer. But I don't even know if they're actually already commercially available.
Hi, Many thanks for the quick reply…I never knew batteries could be so confusing. I've taken your advice and have decided to go for lead. I have checked, and as yet, TMF and TPPL are not available yet, but I'm bombarded with either VRLA, AGM or GEL batteries. Seeing as I can't get hold of a TMF or TPPL, should I just go for a standard lead acid ? I was going to go for an AGM but have read that they are not as reliable. Also, should I change my charger ? I bought it from a golf retailer, and I really dont think it does the battery any favours. Would I need a specific one depending on the battery I go for ?
Many thanks.
VRLA are not recommended for electric vechicles, they do not last long. Gel are fine for a golf cart, but I don't know if you will have to change charger.
Thanks for all of your advice, greatly appreciated.
Just a note: most of the comments above about the life of the battery has to do with useage, heat vs cold, etc.
However, in a battery that is made up of more than one cell (depending on physical configuration), dropping the battery >> can << affect alignment and thus charging amounts. An example of this occurs with some of the cheaper power supply backup units to provide power backups for your cell phone, music/video player, laptop 'puter, etc.
If you open the case, you might well find a whole bunch of "AA" battery cells, which are themselves built up of several button cell batteries (i.e. watch batteries) stacked together. Obviously, dropping one of those units can quite easily result in a mechanical / physical displacement. This would of course affect the charge storage capacity.
Are yoiu serious?!? How could displacement due to drop ever "change storage capacity"?? Battery will fail, or not; it will not "change"!
Yes, quite serious. Fumble-fingered as I am, I have experienced the reduction of storage capacity, as in a quite noticeable reduction in usage time after charging subsequent to dropping the battery (usually though, after dropping more than once). As to "how" it could happen instead of simply failing outright, I cannot say for certain since I did not autopsy the device. I could offer some conjectures. Depending on the type of battery, perhaps the ion matrix was disturbed (as in li-film?) Or, as I suggested already, in the instance of multi-celled construction, with both serial and parallel units, if one of the units (or sub-units) became "displaced" the overall capacity would surely degrade, or even fail (of course), just like an analogous string of Christmas tree lights. Again, speculatively speaking—since I haven't opened up any dropped (degraded) units.
It's more probable a damage to the INSIDE of a single cell rather than cells displacement: electrodes rupture?
Lithium batteries manuals suggest to trash batteries which got damaged when dropped (of course talking about big batteries, several Ah).
Michael Riggs, from November 29 2010 comment, I think your idea has been used by Tesla Motors.
my mobile battery suddenly got bulged i dont wat to do and
y.Now i want to know y it got bulged and whether it will explode..
pls need reply..
What is it written on the battery label?
Anyway, keep it away from any wooden or plastic object (i.e., leave it on the floor away from furniture), as if it is NOT LiFePo4 based it CAN explode/burn!
(especially if LiPo based)
thanks Mr jumpjack ..actually it is 3.7vLi-ion battery..
yah my mom got scared n thrown into garbage…
Now it's too late, anyway for the records: before throwing away a battery, don't forget to put some duct tape over its terminal, to prevent short circuits in case it gets in touch with metal objects: both short circuit itself and high temperature reached by battery due to short circuit can cause a fire.
thanks Mr jumpjack for fast reply to my queries..
I got a lithium battery pack for my ski glove. On high it last for 2 hour, 4 hours for medium but on low it only last 3 hours. Why does the battery not working long on high? Does the cold weather affect the batteries from operating at its peaks power. Would it be better if I use some type of extra insulation around the battery pack so the battery would be cold.
All batteries (lead, lithium or whatelse) suffer in cold climate; they behave at best around 27°C, standard temperature at which they are tested (and labeled).
Bot charging and discharging them at low temperature reduce their capacity/duraton.
Can anyone tell me what the most efficient solar battery for so I can be removed off the power grid? and who manufactures it. I am having issues with the power companies about my solar rebate.
I think Thin Plates Pure Lead are the longer lasting. They cost more than classic lead batteries but less than lithium batteries.
Dear all , I am working in a Lithium battery company, any problem about the Lithium battery please email to me firstname.lastname@example.com I will provide the professional answer
I have two lithium ion batteries, each labeled 3.7 v, 6.4 Wh. I charged both of them fully. One now reads 3.99 volts, and runs my cell phone just fine. The other reads 4.14 volts, and the cell phone does not operate with it. What is happening? Is this too much voltage? Is there some sort of cutoff switch in either the phone or the battery if the voltage is too high? Is there a safe way to lower the voltage, other than waiting for a very long time (It has been three weeks, and the 4.14 voltage has only dropped to 4.13 volts)?
I am an RC model airplane flyer, using all electric motors and Lipo batteries..
I have come across Li-ion batteries from a lap top computor and was wondering, if separated, can I use three for power on my motors?? 12V or more??
The li-ion ones I have are CGR 18650 CE and eac h cell measures 4.14Volts now..
What is your comment on using this for my hobby??
Dear Art
lap top computor Li-ion batteries can not to discharge at high current…..but the RC model airplane need very high power , So DO NOT use this for your hobby, it is dangerous. you can buy the RC Lipo battery for your hobby

I have a samsung smxf44 camera which takes a lithium ion battery. There are several
after market companies that offer batteries which are compatible. Recently bought one that claims will replace my camera battery model IA-BP210E. 3.7V. The battery is a Power 2000 professional digital battery. It claims to be 2400MaH which may be higher than the original battery. I understand this MaH has to do with how long the battery will keep a charge. Am I correct?
There are several companies selling replacement batteries for Samsung. I get no message on my camera that the battery is not compatible.
In any event, the battery will not fully charge or keep a charge and I am returning it.
Should I ask for a replacement or a refund?
Last question. Are lithium batteries dated so that I can tell whether I am getting an old or a new battery?
Thanks for any help you can provide.
Dear Sylvia Heath, would you please email to me email@example.com Edward

in my view li-ion is best and cost effective.
I need that what is required to recharge the lithium iron battery?
which structure is convenient for running fruitful research in lithium ion battery?
dave is cool
There was a comment re Lithium not being the lightest metal and the comment mentioned Hdrogen is Atomic Mass 1 while Lithium is Atomic Mass 3 - Hydrogen however is not ametal so the text is correct Lithium is th elightest Alkali metal
I'd like to know if there are H emission during charging phase. In other words to charge electric vehicle is possible without any special requisition.
Many thanks for a your answer
li-polymer vs li-ion battery
Which one is best for the smart phone ( has a config 4G n/w, 2GHz processor, 2GB RAM, 13 MP cam)
I use Li ion battery in daily life.Which is the best.
These large 18 volt rechargeable batteries, in power tools, what is the cost to recharge them each time. I read that a mobile phone battery, charged every day, would be around ten cents for the whole year. How do these huge heavy batteries compare?
I'm replacing a 7.2v Varta 250mAh NiMH backup battery pack from an appliance that has an 8.4v constant charge. I was intending to replace the battery with 2pc of ICR14500 (7.2v) with protection chip built in.
My question is, regardless of performance, life, suitability, etc. Will the ICR battery explode or just fail?
I use a Turnigy 5000mAmAh 4s1P 14.8v 20C hardcase pack in my ultralight. After leaving it in the plane for a month or so, with temps in the teens and twenties, I got only a series of clicks when I tried to start the plane. I removed the battery and charged it in my balance charger to full capacity. The plane will now start. Do you think the freezing weather harmed the battery in the long run or will it take several of these freezing episodes to damage it? Probably I should take it out of the plane if freezing temperatures are expected. What do you think?
I have Li-ion battery in my mobile and a power bank which is Li-poly battery. Can I use that power bank to charge my mobile
Hello all- My "out in the woods" surveillance camera uses 8 AA batteries. In eastern PA, with use from April to October (staying always outdoors), low temp can be expected around 0 F., and it is late at night that I would expect the camera to be tripped (if at all). It is not very active as it is surveillance. I don't want to buy more than one set of batteries per season (is that possible?) and I don't want to spend any more than necessary. I can go rechargeable or disposable. So, for examples- alkaline is bad in the cold, lithium is expensive, lithium-ions recharge unevenly, etc.
What should I buy?
Oops, I mean (above) freezing, not 0.
I have some informatio about:
" Various additives for applicable electrolytes at the lithium-ion batteries "
Thank you for your attention.
My employer just invested in a new universal remote that has a lithium ion battery in it. It is replacing another remote that also used a lithium ion battery. The battery on the old remote didn't seem to last longer than a year. I live on an island that is very humid and surrounded by the ocean, it doesn't sound like it is worth keeping an extra battery around, should the current one start to fail. I need to make sure that remote is always operational. Any suggestions?
What is the difference between the carbon electrode used in Li ion batteries and a normal Leclanche cell?
I have read through the thread and have not seen this question.
I am running a survey robotic total station using Li-ion batteries and looking for compatible replacements/extras. What are the differences in batteries marked Li-ion20 and Li-ion00 or batteries just marked Li-ion? Should they be compatible?
Thanks for any explanations.
On purchase of a new 3.7v volt rechargable (mob ph) lithium battery some suppliers advise to full charge 4 times before use (8 hour charge period), others make no mention of this.What is accepted initialising and discharge current of a new battery before use please
What batteries would serve best in portable solar kits. Kits that use a 10 watt panel, 10 amp charge controller and a 100 watt inverter! Currently using 2, 10 amp hour acid sealed batteries which provide 6 hours of KED light via 3, 5 watt bulbs and a 2.5 watt LED fan. Thanks

thanks for da infomation
Where can I find a reference for a typical battery construction with all detailes?
your site is informative
What should I do when the battery fallout of my phone?
Should I put it back ?
If a Li-ion battery has been put on a NiCd charger and run will the battery be any good if put on the correct charger or will it be stuffed.
The global lithium production is composed for sustained growth in the years ahead. Polymers followed by li-ion batteries application are expected to be the largest contributor to the future growth in the global lithium market through 2020. Between 2015 and 2020, the overall lithium consumption will likely post 11.93% YoY growth in terms of volume. Chile and Australia are the largest producers of lithium followed by China, Argentina, Zimbabwe and U.S.A among others.

The comment about a liquid battery. Liquid is heavy, 10+
pounds per gallon, that's why such a push for dry cells, plus the mess of liquid. When you put 10 gallons of gas in your car, you are also adding about 100 lbs. There are cell phones now with a type-c usb rapid charge system, 15 minutes can give up to 10 hours of use. When a car battery system can produce these type of results it will happen, but for now the logistics of an electrical vehicle is far off.
I have a lithium ion battery pack (18650) five battery's. When placed in my edger or blower these units will run for a short period of time then slow down and stop. If I wait for two minutes the units come on strong and again after a short period of time they slow and stop. Checking the voltage it back at 19 volts is there a problem with the battery breaking down internal then repairing it self or something in the protecting circuit.
Yes I need hands on fancy Li battery for personal use against enemies. I hold very low monetary value of US dollar, but no problem because I will pay you back once I cause country to fall. I offer $34 for battery to allow charger of atom splitter in new device.I willing to negotiate, yes? Please use email if interest is drawn.
I replaced all of my wall clock batteries with AA Li-ion batteries two months ago, but after learning that they have a higher voltage than standard alkaline batteries, I am wondering whether this was a wise choice. The clocks are working fine but is the higher voltage likely to shorten their life?
Also, is it possible to replace garden solar lights with rechargeable Li-ion batteries or will they damage the LEDs?
Grateful for any advice on these.
nice to read those first comments after 6yrs. nice also to notice how li-po's are improved during the time.
Has anyone found another source to purchase replacement Li-lon batteries for a Inogen One oxygen concentrator or a charger?
Thanks for all help
Can the same charger be used for a Li-ion and a Li-ion polymer battery?
Thank you
Could a lith-ion battery be used on solar gokart?
As lithium batteries lose capacity, performance and get more dangerous under charging condition by the aging, why manufactures do not print the production and the expiry date on them?

The great Sergio Pininfarina has passed. Is there any designer working today who could fill his shoes?
Much as he's been criticized over the years, most notably by Chris Bangle with the "What makes the PhoeniX a Saab?" line, we are big fans of Jason Castriota and his archways of aerodynamics. We've heard he's a spectacularly nice guy and we'd be happy to see him running a company the size of Pininfarina.
Who do you think is the best living car designer?

Post subject: Jibing: Front Foot Magic
Been jibing mostly dry for 20 years, but had a chance to take a wave sailing lesson from Matt Pritchard in Maui last winter and got lots of feedback.
One thing we worked on was front foot pressure.
Then I noticed that both Matt and Wyatt emphasize front foot a lot in their jibe tips. This emphasis seems new to me, maybe I missed a memo back in 1993? I formerly thought "commitment" meant getting all weight onto the back foot.
Anyway all summer during flat water I've been grinding on the front foot and what a difference. My goal has been as Wyatt says to try to rip the front strap off the board by lifting my heel up and bracing the top of my foot against the strap. I had been cheating before -- sometimes getting the heel up sometimes not.
Now as I start the downwind turn the board feels much more slippery. It accelerates instantly and the apparent wind drops much more quickly. This leads to an earlier switch / flip and more speed out which is the key to the planing jibe.
It feels like magic. Now I feel like I'm jibing on two feet on a stable platform, not hurtling through big chop on one foot. My OP jibing is improved because I'm accelerating much more smoothly. I can start the jibe from a nice stable beam reach instead of flying downwind on a broad reach first which I always hated in heavy conditions. The new challenge is catching up with how quickly things are happening which is a good problem to have. I still have to remember to do it -- it's hard to put things into muscle memory at this point.
Anyway if you are not a nerd skip the rest of this post.
So all summer I've been wondering why it works so well. I don't need to lift the windward rail on my 85 L board. Yes, it gets your weight fwd with ankle flex but we all know if you overdo the "weight forward" thing even slightly in OP conditions you will bury the rail and the board will slow down and the body will not. Does this move with the front heel just accidentally find the sweet spot between weight too far back and too far fwd?
So here's a theory: bracing the front foot makes the board a more rigid shape that feels lower resistance from the water. If all my weight is on the back foot then every change in water contour changes the attitude of the board as it carves. The water "sees" a rubbery, wobbly shape trying to carve through it and the water knows to resist.
But with both the top and the bottom of the board braced the board is now a rigid, clean shape that slices through the chop effortlessly. I am in control of board attitude, not the water.
Would be interested in any other observations about how it feels or why it works.

I don't know or care about the latter question, but AMEN to the former statement. I get the same sensation from thinking "hip thrust" rather than "ankle lift", but the ankle lift does reinforce the forward segment of the hip thrust. However we achieve it, a fast, tight, carve initiated full tilt from the incoming beam reach beats the hell out of adding the control and timing challenges of full speed broad reaches, rough water, and jibing sail, board, and rider all at the same time. I can't even imagine how great sailors add spatial awareness and freestyle tricks to that multitude of challenges.

I am now learning how to carve jibe and trying to get a repeatable carve initiation. I do it on a Kona One with long and thick rails. I figured last week that the only way I can do it repeatably is by pulling up on the front strap while pressing on the leeward rail with the back foot. Pulling up for me is forcing the knee up and in the turn. Instead of raising my toes to pull, I let the heel go up and I then feel on the ball of my foot since the arch is pulling on the strap.
It gives me the same feeling: I am in charge, and turn how I decide, instead of having the chop and the board deciding by themselves.
My goal is to perform my first planned gybe. Instead of doing a wide arc and slowing down waiting for a problem to happen for a full 4 seconds, I aim for a quicker turn as suggested by iso elsewhere. I hope I will loose less speed that way.

I like the "bracing the board" theory, and I think that's definitely part of it. But it's also about rail pressure.
An interesting thought expirement is this: imagine that your feet are in exactly the same position heading into the jibe but you don't have footstraps. If you had most of the weight on your back foot, and your rear heel on or close to the center line, you could carve with rear toe pressure. But if you tried to weight your front foot (again, with no straps), you couldn't carve the board because it would want to head up. Therefore, I think one could argue that exerting upward pressure on the front strap is necessary to counteract what would otherwise be windward pressure on the rail due to increased weight on the front foot.
Also, I think the Wyatt/Matt advice is one of those tips that mentally makes a difference. There's a relatable, repeatable, and tactile sensation to lifting the front heel, and that tends to put the rest of the body in the right position.

Well guys, don't really want to flog this dead horse again, but if you took your front foot out of the strap and put it right behind the mast step, then stepped on it, you'd get even better results. Probably not a good idea while wavesailing, however.

I love the Spennie, and I use it from time to time. To me the huge benefit is that it instantly forces you to surf instead of sail, and that has lots of benefits, including putting you in the right posture (your a can't be sticking out that way), making your eyes scan the surface ahead, etc.

another way to say it is by thinking in terms of weight forward. If you put, or force, your weight forward into the turn your back foot is all but forgotten and you keep the board flat and speed constant. your weight inward is really what makes the board turn and stay into the turn. You don't need to be gentle to control the board with your back foot anymore, the body weight is what will make you turn.
If you've laid the rig down you can flip it early, recover from the other side, then have plenty of time to switch feet.
in this scenario you MUST keep your front foot in the strap for better control.
(sorry spennie, your technique will never help someone who is trying full on speed jibe)

weight too far forward wets the board too much, and stalls. too far back, one wheelies and stalls. all depends on gear and conditions. makes for much typing, and pondering. best to sail often. jibe and tack lots.

that's the best advice. I see people going on super long "voyages" when windsurfing and, sure, they are having fun, but spending what seems to be hours on one tack. most of the people I see doing this can't jibe for beans and they only attempt a few jibes a day.
of course, to each his/her own, but I prefer to go on short runs and see how many jibes/tacks I can do in a specified amount of time.
have fun!!!

Those defy physics, but if you jibe better buying them, that counts for something.

Every year, American public schools spend $2.2 billion replacing teachers who leave the profession.
But the true cost to the system is even bigger. When teachers stick with their jobs, they build up valuable experience and improve their instructional techniques. When they leave, that valuable experience vanishes. Administrators have to expend time and money – both usually in short supply – training replacements.
Retaining teachers, therefore, could save billions and improve education quality.
Fortunately, preserving the intel experienced teachers have isn't that difficult. It's as simple as mimicking the stat geeks who are revolutionizing baseball and the political operatives who are winning elections.
They're harnessing the power of data. And they're succeeding.
For the first time ever, schools have detailed information on the strengths and weaknesses of individual educators – and the computing power to analyze it. They can also track student performance, rates of learning growth, demographic trends, even the effectiveness of various teaching methods across subjects.
Used correctly, such information could fuel teachers' professional development, empowering them to cultivate their craft and get the most from their students.
Unfortunately, that's not how many school officials are using this invaluable data.
Forty-one states require regular teacher assessments. In most cases, administrators collect data on teacher performance, offer detailed descriptions of their deficiencies – and yet do little to help them improve.
Instead, schools pack their teachers into one-size-fits-all "professional development" programs that are wholly insensitive to the challenges of individual classrooms – and to the learning needs of individual teachers. Students enjoy a half-day off, while teachers are subjected to stock lectures on, say, what regulations they must follow when administering standardized tests.
Every year, the government spends more than $4 billion on such professional development. That's about $1,000 per instructor.
The returns on that investment have been non-existent. American student achievement has remained flat for 30 years. Less than one-third of American high-schoolers can read proficiently. Over a quarter read significantly below grade level. And just a quarter are proficient in math.
Even when teachers get data on their performance – or their students' – they receive little to no instruction on what to do with it and on what will help them strengthen their practice. As one teacher from Chicago said, "They always look at the … data but never talk about the next step; someone has to show us how we can use it to improve."
In many cases, that data can be used for punitive ends. The Los Angeles Times, for instance, publicly ranks more than 11,000 teachers in the Los Angeles Unified School District based on student test scores.
It's no wonder that many teachers have soured on the idea of data-driven school reform altogether. In their experience, it serves solely to embarrass or punish them.
There's a better way. By using education data to drive personalized professional development for each educator, school officials can put the data they're required to collect to good use and raise the skill level of their teachers – without alienating them in the process.
Consider a teacher whose evaluations show that she's having trouble keeping her students focused. Instead of boring her with a three-hour lecture, her administrators could set her up with teacher-development programs keyed to the exact size of her class and the specific nature of the distractions.
Attention-grabbing techniques that work for a group of 12 students won't necessary work for 30. The same is true for single-sex versus integrated classes – or those with varying numbers of non-native English speakers.
Likewise, technology can make evaluations less painful – and more meaningful – for both principals and teachers. A laptop loaded with data from previous observations can allow an administrator to hone in on only those teaching indicators that merit the most attention – and provide instantaneous feedback accompanied by videos of best practices from master teachers.
The stakes are high. Research shows that the No. 1 predictor of student success is the quality of his or her teacher. For instance, a math teacher with even slightly above-average skills increases student achievement scores by nearly 6 percent. That alone speaks volumes. In order to produce better students, we must produce better teachers. The "Big Data" revolution that's taken hold in other parts of our society can do just that.

A former Boulder County deputy who survived a shootout with a gunman near Nederland in 2008 and won a medal of valor for his actions was found dead Thursday afternoon after a resident reported hearing a single gunshot from inside his home near Nederland.
The Boulder County Coroner identified the 51-year-old man as John Seifert, who is a former Boulder County deputy honored for valor after a shootout with a gunman who killed the general manager of the Eldora Mountain Resort on Dec. 30, 2008.
"Like so many heroes, he had a really difficult time handling that," said Boulder County Sheriff Joe Pelle. "That unlocked some real issues for him with post traumatic stress and alcohol."
He said the office worked with Seifert after the shootout to try to get him the help he needed.
"We invested heavily in John in treatment, intervention and professional support, and we couldn't get him over the hump," Pelle said. Derik Bonestroo, who worked at the resort, shot and killed Brian Mahon after announcing at a employee meeting that he planned to kill anyone who did not share his religion. Seifert, a deputy who worked the Nederland area, responded to calls for help and saw Bonestroo speeding away from the resort in an Infiniti and gave chase. Bonestroo pulled over his car and, according to reports, rolled down a window and opened fire on the deputy. Seifert returned fire.
The shoot team concluded that Bonestroo fired 27 rounds at Seifert, who was not struck. However, bullets did strike his marked SUV and he was showered in broken glass as the pair exchanged 49 rounds in a matter of seconds. Bonestroo suffered seven wounds during the gun battle and died, but the coroner ruled he died of a self-inflicted gunshot.
Seifert later learned Mahon was killed. They were friends. Seifert was a four-year veteran of the Boulder County Sheriff's Office at the time and was awarded a medal of valor in 2009 and later left the job about two years ago.
The Boulder County Sheriff's Office reported on Thursday that deputies were called to Seifert's home on County Road 128N, just outside Nederland, on a report of a disturbance. According to reports, when deputies arrived a resident reported hearing a single gunshot from within the home. Seifert was pronounced dead at the scene and no one else was hurt. Pelle said Seifert had friends and former co-workers who routinely checked in on him, wanting to help.
"The news is sad and devastating for a number of his friends who have been trying desperately to help John out over the past couple of years," Pelle said, adding he will require some of them to complete at least one visit with a mental health professional. Several were among first responders to Seifert's home on Thursday. Investigators did not find any evidence of foul play. The coroner will determine the cause and manner of Seifert's death.
Pelle said police work is dangerous in more ways that is apparent. He said for every one officer killed feloniously, four take their own lives.

WASHINGTON — Hillary Rodham Clinton leaves her post as secretary of State next month with a split judgment on her diplomatic career: She's won rave reviews from the American public and the president, but maybe not a prominent place in the diplomatic history books.
Job approval ratings for the former senator and first lady are at stratospheric levels, suggesting that her four years as chief U.S. diplomat could be an important asset if she runs for president in 2016.
But scholars and diplomatic insiders say she has never dominated issues of war and peace in the manner of predecessors Dean Acheson or Henry Kissinger, or laid down an enduring diplomatic doctrine.
President Obama has tightly controlled foreign policy in the last four years — more so even than his recent predecessors. Clinton has had a seat at the table on every key issue, officials say, but she did not "own" any of them.

(AP)—World stock markets were mixed on Friday as investors weighed disappointing U.S. economic data and upbeat forecasts from Intel, the computer chipmaker.
Sentiment has been subdued this week, particularly since a U.S. report on Thursday showed retail sales in the world's largest economy did not grow as much as expected in May. Further denting optimism was the rise in oil prices, which can hurt the growth prospects for companies.
In Europe, France's CAC 40 slipped 0.2 percent to close at 4,543.28 and Germany's DAX lost 0.3 percent to 9,912.87. Britain's FTSE 100 fell 1 percent to 6,777.85.
In the U.S., however, markets managed to eke out gains after Intel said sales of computers to businesses were stronger than expected, a good sign for the broader economy. The Dow was 0.2 percent higher at 16,762.13 and the S&P 500 was up by the same rate, to 1,933.70. Shares in Intel jumped 6 percent.
Traders were monitoring developments in Iraq, where Islamic militants vowed to march on Baghdad after pushing deep into parts of the country's Sunni heartland previously controlled by U.S. forces. U.S. officials ruled out putting troops back on the ground.
"For traders often jaded by seemingly constant news of potential geopolitical risks, the situation in Iraq looks a real concern," said Ric Spooner, chief market analyst at CMC Markets in Sydney. "Markets have been surprised by the speed and extent of rebel incursions into the south."
The U.S. benchmark oil contract for July delivery was up 8 cents to $106.61 a barrel in electronic trading on the New York Mercantile Exchange. The contract rose $2.13 on Thursday.
In Asia, stocks mostly rose on the news that Chinese industrial production rose 8.8 percent in May, in line with analyst expectations, while retail sales grew faster.
The latest numbers fueled hopes that recent mini-stimulus measures by authorities will prevent the economy from slowing too sharply.
"The overall May data confirmed moderate recovery in the economy in the second quarter," economists at JP Morgan wrote in a research report.
Japan's benchmark Nikkei 225 recouped earlier losses to close 0.8 percent higher at 15,097.84. South Korea's Kospi lost 1 percent to end at 1,990.85.

Unfortunately, the power was out for a few hours this afternoon due to the snowstorm. This is a major inconvenience, but what can you do? So the patients and I work through it as best we can.
Not the ortho doc, though. 10 minutes after it went out he came storming out of an exam room and went up to his secretary.
"Suzy! This power outage is unacceptable! Call the electric company and have them turn it back on immediately!"
Pissy and I had a hard time not cackling as he marched back into the exam room.

15 Great New England Hikes
The city is great, but everyone needs a taste of the outdoors from time to time. Here are some of the best places to hike in New England.
Text from LocalAttitudes Outdoor Guides
Mass Audubon's Ipswich River Wildlife Sanctuary, Topsfield
Owing to the sheer size of the sanctuary, you are unlikely to meet many people on the trails; the Ipswich River crosses the southern part of the sanctuary, and Mass. Audubon members can rent canoes to explore the marshes.
Mass Audubon's Ipswich River Wildlife Sanctuary, 87 Perkins Row, Topsfield. www.massaudubon.org.
Duration:Full day
The Skyline Trail at Middlesex Fells Reservation, Medford
Middlesex Fells is as close to wilderness as it can get for a reservation less than 30 minutes away from one of the country's largest cities. Touring the Fells on the Skyline Trail, you may sometimes believe you are deep in the woods of New Hampshire. Indeed, do not mistake the Skyline Trail for a quick afternoon walk. At about 7 miles in length, it is a real hike that can take most of a day if you like to stop frequently.
The Skyline Trail at Middlesex Fells Reservation, Bellevue Pond, Medford. www.fellsbiker.com.
Duration: Half day/full day
Mount Misery, Lincoln
The Mount Misery area in Lincoln is an open, lively place where everyday life continues at the slower pace of the countryside. On these trails, you feel more like visiting some farms away in the north than exercising with fellow urbanites on overused paths. Though close to Boston, Lincoln is therefore a great place to breathe after a hard week and to reconnect with the outdoors.
Mount Misery, Lincoln. www.trails.com.
Duration: Half day
Cape Cod's Lietenant Island, Wellfleet
Away from the crowds, Lieutenant Island is an area off the beaten track, which offers a unique environment for a hike along the shore. A small hill dotted with a few summer homes tucked beneath the pines, the island is connected to the mainland by a narrow causeway and an old wooden bridge.
Cape Cod's Lietenant Island, Wellfleet. www.trails.com.
Cost: $5
Duration: Full day
Plum Island, Newburyport
Plum Island is a 6-mile long barrier beach that extends south of Newburyport. Most of it makes up the Parker River Wildlife Refuge, which nearly 300 bird species visit seasonally. This long hike will take you through the extraordinary diversity of Plum Island scenery.
Plum Island, Newburyport. www.newburyportchamber.org.
Cost:$5 per person/$2 walk-in
Duration: Half day/full day
Myles Standish Forest, S. Carver
Myles Standish is one of the largest and most remarkable forests in Massachusetts. Its vegetation is also very different from that found elsewhere in the state: With many pitch pines and scrub oaks, it very much looks like the woods encountered on Cape Cod and the islands.
Myles Standish Forest, Cranberry Road, S. Carver. www.massgov.com.
Cost: Free
Duration: Full day
Noanet Peak, Dover
This is Boston's best kept secret for hiking. Less than an hour away from the city, Dover's Noanet Woodlands delivers nearly the same excitement as larger reservations like Blue Hills, but with a more diverse environment of woodlands, pine forests, meadows, and ponds and a quieter setting away from major highways.
Noanet Peak, Dedham Street, Dover. www.thetrustees.org.
Cost: Free
Duration: Full day
The Acorn Trail at Great Brook Farm State Park, Carlisle
Carlisle's Acorn Trail offers a surprising feel of being quite far from the big city, and although not a difficult hike, it will be a nice workout for seasoned hikers. This loop takes you through cultivated fields and woodlands, following a narrow and winding trail through the forest and up a small hill. There is one main climb into the forest, and the trail can be rocky in places.
The Acorn Trail at Great Brook Farm State Park, 984 Lowell St., Carlisle. www.mass.gov.
Duration: A few hours
The sand dunes on Crane Beach, Ipswich
Ipswich's Crane Beach is managed for both conservation and recreation – wildlife and people. A key feature of Crane Beach is its dunes. Crane Beach is indeed one of the very few areas in New England where you can actually explore sand dunes through a trail network open to the public.
The sand dunes on Crane Beach, Argilla Road, Ipswich. www.thetrustees.org.
Cost: From $7 per car
Duration: Half day/full day
Hiking on Cape Cod National Seashore
The Cape Cod National Seashore, which spans the entire eastern shore of Cape Cod, is simply the best place in all New England to enjoy a long hike on the beach. Actually, few other countries can boast a similar setting, with more than 20 miles of uninterrupted beach. The Nauset Marsh Trail bridge, howeber. was destroyed in a 2012 storm. The trail is still open during replacement work but check at the Salt Pond visitor Center for current conditions before heading out.
Cape Cod National Seashore. www.nps.gov.
Duration: Full day
Skyline Trail at Blue Hills Reservation, Milton
Blue Hills Reservation in Milton is certainly the best destination for hikers looking for a great experience without the hassle of driving for 3 hours to New Hampshire or Maine. It has more than 125 miles of trails for all levels, in a setting that is surprisingly rugged and challenging.
Skyline Trail at Blue Hills Reservation, 695 Hillside St., Milton. www.mass.gov.
Cost: Free
Duration: Full day
The Great Island Trail, Wellfleet
The Great Island Trail in Wellfleet is one of those magical places along Cape Cod Bay, balancing between land and sea; you will walk in a pine forest one moment and see algae on the trail the next moment. Definitely one of the best places for hiking in New England, and a must for those who like solitude.
The Great Island Trail, Wellfleet. www.nps.gov.
Duration: Full day
The direct route to Mount Monadnock, Jaffrey, N.H.
Considering that it is relatively close to Boston, we believe New Hampshire's Mount Monadnock offers the best trek opportunities in New England — summits in the White Mountains are farther away and require longer climbs before emerging above timberline. Overall, there are 40 miles of hiking trails across the Monadnock State Park.
Mount Monadnock, Route 124, Jaffrey, N.H. www.nhstateparks.org.
Cost: $3 per person
Duration: Full day
Mass Audubon's Wellfleet Bay Wildlife Sanctuary, Wellfleet
The Wellfleet Sanctuary offers miles of trails in a preserved environment of meadows and wetlands – definitely worth the trip from Boston. Trails are not extremely long (around 5 miles for our hike) but offer great views and many opportunities to stop and just relax on the grass.
Mass Audubon's Wellfleet Bay Wildlife Sanctuary, 291 State Highway, Route 6, Wellfleet. www.massaudubon.org.
Cost:5 per person
Duration: Full day
Hale Reservation, Westwood
This is another one of Boston's lesser known outdoors areas and a perfect spot for hiking. Located in Westwood, about 10 miles southwest of Boston, and easily reachable from Route 128, crisscrossed by a good trail network, Hale is the place to go if you have a few hours on your hands and want to get some fresh air and a good workout outside.
Hale Reservation, 80 Carby St., Westwood. www.halereservation.org.
Cost: Free
Duration: A few hours

You pull yourself out of bed, bring your coffee to the front porch, and there—right in front of you—is the vast expanse of the Grand Canyon.
That's the appeal of staying at El Tovar, which has graced the rim of the canyon since 1905. But it's hardly alone; you'll find great national park lodges all over the U.S. and Canada. And staying at one doesn't mean camping and freeze-dried dinners. The best lodges offer gourmet food, personalized service, and rustic yet often elegant interiors.
Many are landmarks dating back to the park system's early days. In 1903, officials at the Northern Pacific Railroad were inspired to create a lodge with local logs and stone. The result, Old Faithful Inn in Yellowstone National Park, has a towering lobby that became a model for national park architecture. For something a bit more modern, try the 23 renovated suites and heated outdoor pool at Alta Crystal Resort by Mount Rainier, WA.
Related: A Guide to Kings Canyon National Park
You might even encounter a celebrity or prime minister during your stay. (The El Tovar staff once had to hush Paul McCartney because a guest complained about his piano playing.) But that doesn't mean the prices are out of reach. Double rooms start at about $207 at El Tovar and $180 at Oregon's Crater Lake Lodge.
Find out how the right lodge will improve your next national park visit.

Welcome to Madrone Art Bar"Madrone Art Bar is a full-on art experience. Paintings, photographs, mixed media, sculpture, video, film, design, fashion, music, spoken word, and dance share time with live music, DJs and specialty cocktails to round out this NoPa hotspot" (7x7 Magazine)
"What: What on earth could cause a line out the door of a Western Addition art bar on a Monday night? A sweaty, sexy, throwback dance party that is guaranteed to improve your mood the moment you set foot in the door. Motown on Mondays weekly dance party vibe is so infectious, countless self-imposed weeknight curfews have crashed and burned within these four walls."
The 20 best things to do in San Francisco,
"After a trip abroad, many long for Madrids familial nightlife. The proprietors of Madrone are cultivating just that. Their multi colored venue resembles a Surrealists studio. A light sculpture in the window, oil paintings snuggled close together on the walls, and a curious organ of spirits behind the bar. Patrons dress as they might for a sangria, at the house of a young spanish friend, casually extending their arms for hugs and handshakes, sharing drinks and chatting. There is as much variety to the nightly programing as there are berries on a madrone tree. Live MCs rap and local DJs Spin into the calendar between popular funk and soul mixtape parties."
Louis Vuitton, Americas Cup City Guide. 2013
"A critical aspect of assessing the significance of Madrone was understanding how it subverts conventional and settled notions of art and its presentation, through a strategy of bringing and blending together a multitude of creative forms of expression to constitute a living artistic spatial assemblage. I began to seriously consider how Madrone serves as a vehicle for questioning and expanding common assumptions of what constitutes the nature of art, as well as its potential for challenging the notion of museums and galleries as the sole locations for exhibiting and defining the meaning and validity of art. " SF ARTS QUARTERLY by Anthony Torres
"Sometimes you are in the mood to gaze at inspiring works of art. Other times you are in the mood to drink potent cocktails. Now and again, you are even in the mood to dance your pants off. On a not-so-rare occasion, you are in the mood to do all three. If you are having an all-three kinda night, the hip and happening Madrone Art Bar is where to head." (AOL CITYS BEST)
"Bay Area Female DJs Shatter Sexist Notions....at Madrone Art Bar, a trendy little venue that looks as if it were interior-decorated by Jeff Koons and Banksy." (SF Chronicle)
"Madrone introduces a new frontier in the world of theme parties while it simultaneously expands peoples minds in the world of art; the walls are covered with continuously changing artworks exhibited throughout the bar. Attendees are able to check out artists that are both new to the scene and who have been covering walls with their pieces for years. All forms of creativity have an equal opportunity as Madrone shares the work of sculptors, painters, photographers and anything else a person puts their mind to. This is beneficial for those who need to take a breather from dancing his/her ass off to Princes "Erotic City" as they are continually submersed in the bars atmosphere by admiring the work of Jerimiah Jenkins, Micah Rivera, or Dennis McNulty." (Breakthruradio.com)
Because the highest form of art is drinking with friends!

The new federal strategy for the Chesapeake region uses rigorous regulations to restore clean water, implements new conservation practices on 4 million acres of farms, conserves 2 million acres of undeveloped land and rebuilds oysters in 20 tributaries of the bay, according to a May 12 press release.
"This strategy outlines the broadest partnerships, the strongest protections and the most accountability we've seen in decades. It's a new era for our work on the Chesapeake Bay," said U.S. Environmental Protection Agency Administrator Lisa P. Jackson, who chairs the Federal Leadership Committee for the Chesapeake. "Through President Obama's leadership and the commitment of many active stakeholders, we have an historic opportunity to restore the environmental health of these waters and the vibrant economy of this community."
To restore clean water, EPA will implement the Chesapeake total maximum daily, expand regulation of urban and suburban stormwater and concentrated animal feeding operations and increase enforcement activities and funding for state regulatory programs.
The agency also released a guidance to help federal facilities reduce their pollution to the bay. The guidance provides federal land managers with the help they need to implement the best proven tools and practices to restore and protect the region's waterways and the bay. The cost-effective tools and practices outlined in the document are indicated by current scientific and technical literature to be the most state-of-the-art approaches to reduce water pollution from nitrogen, phosphorus and sediment. Others in the Chesapeake Bay watershed, including states, local governments, conservation districts, and watershed organizations, can also benefit from the information presented in this guidance.
The U.S. Department of Agriculture (USDA) will provide farmers and forest owners with the resources to prevent soil erosion and keep nitrogen and phosphorous out of local waterways. The agricultural agency will target federal funding to the places where it will have the greatest water quality impact and ensure that producers' conservation efforts are accurately reported. USDA will also lead a federal initiative to develop a watershed-wide environmental services market that would allow producers to generate tradable water quality credits in return for installing effective conservation practices.
"A thriving, sustainable agricultural sector is critical to restoration of the Chesapeake Bay," said USDA Secretary Tom Vilsack. "We will help the bay watershed's farmers and forest owners put new conservation practices on 4 million acres of agricultural lands so that agriculture can build on the improvements in nutrient and sediment reductions that we have seen over the last 25 years."
The Department of the Interior will launch a collaborative Chesapeake Treasured Landscape Initiative and expand land conservation by coordinating federal funding and providing community assistance. Interior will also develop a plan for increasing public access to the bay and its rivers.
Secretary of the Interior Ken Salazar said: "My department, which has 13 refuges and 51 units of the National Park System throughout the watershed, will play a key role in the plan, working hand-in-hand with other federal agencies, states, local communities and other stakeholders to restore this national treasure cherished by so many."
The National Oceanic and Atmospheric Administration (NOAA) and the U.S. Army Corps of Engineers will launch a bay-wide oyster restoration strategy in close collaboration with Maryland and Virginia that focuses on priority tributaries, expands commercial aquaculture and bolsters research on oyster stock, habitat and restoration progress. Oysters are among the bay's most struggling species.
The strategy includes several overarching approaches:

A clear, colorless gas that performs a number of important functions in the body. It seems to play a role in several medical conditions, including septic shock, dementia, and impotence, and it may partially account for the high rate of heart disease seen in people with diabetes. Nitric oxide is considered such an important chemical in the body that the journal Science named it the "Molecule of the Year" in 1992, and in 1998 three scientists won the Nobel Prize in Medicine for researching its role in the body.
Scientists have long been familiar with nitric oxide as a component of car exhaust, cigarette smoke, and air pollution, but it wasn't until the late 1980's that researchers discovered that mammal cells also produce the gas and use it to communicate with other cells. Abnormalities in the body's production of nitric oxide have been implicated in high blood pressure, atherosclerosis (narrowing of the arteries), diabetes, erectile dysfunction, and stroke.
Scientists are furthest along in their understanding of nitric oxide in the area of heart disease. Normally, cells lining the inner wall of blood vessels secrete nitric oxide, which travels to the muscle cells around the blood vessels and causes them to widen, allowing easier blood flow. Impaired nitric oxide production may contribute to constricted blood vessels, high blood pressure (especially in the 90% of cases with no identifiable cause), and atherosclerosis. Scientists now know that nitroglycerin and similar drugs dilate blood vessels and help alleviate angina – temporary chest pain resulting from insufficient oxygen to the heart – because the drugs release nitric oxide. Nitric oxide also keeps blood platelets from clumping together and sticking to the inner walls of arteries, protecting the body from blood clots and atherosclerosis. Researchers are currently looking into drugs called nitric oxide donors that will increase nitric oxide levels in people with heart disease.
Nitric oxide also helps to initiate erections. During sexual stimulation, nerves in the penis release nitric oxide. Nitric oxide converts the chemical GTP to cyclic GMP, which causes the corpora cavernosa – the rods of spongy tissue within the penis – to fill with blood and become erect. Researchers believe that men who smoke and men with diabetes, atherosclerosis, or high blood pressure may have defective nitric oxide production, which can cause impotence. In fact, the discovery of nitric oxide's role in the body led to the development of the popular impotence drugs sildenafil (brand name Viagra), vardenafil (Levitra), and tadalafil (Cialis). Like nitric oxide, these drugs work by increasing levels of cyclic GMP in the penis.
However, nitric oxide is not purely a good thing, since too much of it can contribute to severe medical problems. When there is a bloodborne infection, cells of the immune system produce vast amounts of nitric oxide to destroy the pathogen. This dilates blood vessels and can cause blood pressure to plummet – a condition called septic shock, which kills about 100,000 Americans each year. Also, when brain cells are deprived of oxygen during a stroke, they release lots of nitric oxide, which is believed to cause much of the destruction of brain tissue seen in strokes. To treat these attacks, researchers are trying to find ways to selectively inhibit the production of nitric oxide where it is harming the body – without decreasing the overall levels of beneficial nitric oxide. Research into the potential clinical applications of nitric oxide is still in its infancy.

The Consumer Electronics Association (CEA) has announced the formation of a new committee to advance the standardization of the Modular Communications Interface (MCI) specification to create a path for smart grid-ready products.
The MCI specification, created by the Universal Smart Network Access Port (USNAP) Alliance and based on research from the Electric Power Research Institute (EPRI), will allow manufacturers of consumer products to build Smart Grid-ready products that can obtain energy information from digital meters and energy system interfaces regardless of the communication technology used.
USNAP enables HANs (Home Area Networks) to connect to smart meters, energy gateways or other devices within the home. USNAP utilizes a standard modular interface that enables products to be compatible with any communication network through plug-in communication modules. Numerous products are already available with USNAP capability, and the recently announced Zonoff Z-Wave Bridge Platform uses USNAP and EPRI standards to allow home networks using wireless Z-Wave products to communicate with other communications technologies like ZigBee, which is used in many smart meters. Z-Wave products such as wireless thermostats and plug-in modules are being deployed in entry-level home connectivity/security/energy management systems by large service providers like ADT, Comcast, Verizon, Vivint, Alarm.com and likely AT&T.
"This new specification addresses a significant gap in the Smart Grid for a unifying technology that enables a range of consumer products to respond to demand response events," said Brian Seal, technical executive for EPRI.
"This committee is designed to accelerate the adoption and growth of Smart Grid ready products," said Brian Markwalter, senior vice president of research and standards for the Consumer Electronics Association. "We're eager to build on the significant efforts of USNAP and EPRI to create this standard by further addressing the needs of manufacturers, utilities, service providers and consumers alike."
At the request of the National Institute of Standards and Technology (NIST), independent modular interface initiatives from the USNAP Alliance and EPRI were merged into a unified specification that identifies the interface between a Universal Communication Module (UCM) and a Smart Grid Device (SGD). A NIST working group completed the MCI specification, and it was formally submitted to CEA to facilitate creation of the standards development project.
"Consumers benefit from the selection of Smart Grid ready products that can be used anywhere in the country," said Jon Rappaport, chairman of the USNAP Alliance. "Manufacturers benefit because they can build standardized products capable of working in any service territory. Utilities benefit because this specification reduces the risk of stranded assets."

Located at the point where Europe meets Asia, Istanbul spans both continents and is the place where cultures mix and mingle: where east meets west and ancient meets modern.
Click here to jump to the photos >
And though the city is traditionally known for its mosque-dotted skyline and its spectacular historic monuments and palaces like the Aya Sofya and Topkapi Palace, today Istanbul is taking on a new role as hipsters, foodies, artists and fashionistas are quickly transforming the city into a bastion of cool.
Perhaps it began to truly morph into its current shape around 2010, when Istanbul was designated as the European Capital of Culture and it underwent drastic renovations to prepare for the year it hosted a series of cultural events. Since then, the city has become a playground for the young and hip.
Today all around the district of Beyoglu, on the European side, once-crumbling buildings have been renovated and turned into fancy boutique hotels, designer shops and trendy restaurants. The neighborhood of Ortaköy, which was once a small fishing village, is now home to sophisticated nightclubs and restaurants right on the Bosphorus. And entire swaths of the city which were once run-down and neglected, given over to prostitution and other illicit activities—like the leafy neighborhood of Cihangir—are now gentrified hotspots.
And there's so much ongoing construction—the city is constantly buzzing with the sounds of jackhammers and machinery—that the face of Istanbul will continue to be transformed.

Attention blokes driving through the Australian Outback, Scott Forstall, or anyone else who needs to actually get where they're going: Google Maps may natively return to iOS as early as tonight, according to anonymous sources as cited by All Things D.
Not a whole lot to say other than it can't happen soon enough, and that it's been about a month since we heard Google's app was in late-stage testing after being ousted as a built-in feature over the summer. While Apple's foray into the wide wide world of mapping hasn't necessarily been an abject failure, neither has it been up to par with Google's product, or, for that matter, what we'd expect from Apple.

"Hasbro was hoping you wouldn't notice" would also have been an acceptable answer.
I think it's a matter of Hasbro knowing they have collectors by the balls, and of course knowing this will sell like everyone's mentioned. The Disney Park stuff moves to the kids wanting souveniers and this will too. I'm pretty set now on not getting one myself. I just can't see me caring about Teek or Taint that much.
while this is a "souvenier set", you gotta remember this is also a "goodbye set" - and in that sense it has more of a collector nod to it. This set is coming out in the end of May iirc, and and Star Tours is supposedly closing down for its upcoming re-vamp in October - and then will not be re-opening until 2011. If the kiddies/collectors don't gobble these up before October (roughly 5 months) - I would think Hasbro/Disney will be sitting on them
