ELI5: Why do batteries sometimes work a little while longer when you take them out and put them back in?

Batteries in something like a remote control only make Contact is two places.  Corrosion tends to build up in tiny amounts where the charge jumps, halting the flow of electricity. By pulling out the battery and putting it back in you clean the contacts. Battery is most likely near death anyway because there would be time to corrode otherwise.
