ELI5: Why is it that when my tv remote "dies", I can pull a battery out, put the same one back in, and it suddenly works again?

The battery contacts and the contacts in the remote control corrode very slightly due to the electricity flowing through the connection. When you move the batteries (you can just roll them in place for the same effect) you clean the contact points slightly and allow better electrical flow. The batteries are still probably close to death due to the time they have been in use, but 'exercising' those contact points gains you a little more battery life.
