Why do batteries go dead in an unused flashlight while the rest of the batteries still in the pack stay good?

You'll also notice that alkaline batteries stored in a pack usually don't leak, while ones stored in a flashlight have a much higher chance of leaking. I'd be interested to see if electron migration through the long connected leads is responsible. Another theory (my off-the-cuff theory) is that the battery begins a slow chemical or physical degradation after a single short usage. Perhaps test by putting batteries in a flashlight and resist the urge to click it on for a moment "just to check that they work".

that's an interesting idea. I've been searching scholar for some time, but not found anyone else even trying this yet. Think we could get a grant off queen Cindy to give it a go?
