If you were to find a battery on a shelf that is, say 10-20 years old, what type is battery is most likely to have any charge left on it? I understand it varies, and that it would most likely be dead, but I'm curious in which situation you might possibly have any juice left.
Preferably something commonly used like a 6V lantern battery. Thank you.
