Battery leakage

[lightlover]

A guy who should know once told me that batteries left in a torch still had SOME contact with something. I don't know if he meant by humidity or dust particles or something as yet unknown to science ??
Is that nonsense or what - I've often wondered ......

most batteries leak because they are completely dead.
the chemical reaction that produces electricity eats a hole in the can.
mostly seen in batteries that have been dead several years.

I wondered if it had something to do with still actually making contact. I guess it makes contact on one end or the other, or perhaps there is some leakage through the sides in a metal flashlight.

That may be so, but batteries have years for a shelf-life. I'm sure I've had things leak long before that! Are there some batteries that are better than others for avoiding this problem?

Maybe someone here can explain something to me I've never understood.

Unused batteries seem to have a long shelf-life, but when you put them in, say, a flashlight, but don't actually turn the flashlight on for a long time, they tend to leak.

Why is this? I mean, if the light is off, wouldn't it be about the same as sitting on a shelf?

I am interested in an LED flashlight and they seem to last a long time, but I can see times when I might not use it for an extended period. I won't know ahead of time, so a light in my car is sometimes going to sit unused. Is there any solution to this?

That's interesting. What about Lithium batteries? I've been assuming that having Li batteries for my car flashlights would stop this problem (which I've had several times).

Have I fooled myself?

maybe the spring pressure deforms the seals?
all the leaked batteries i have seen were dead as hell.even the ones in the same group that did not leak.

I actually mark calendar dates to either change or replace batteries.

Sure beats the mess you get for not doing so....
