    Hey guys, I have some aaa nimh energizer rechargeables. Just noticed that two of them are "swollen". The plastic wrap is splitting and it's more of a snug fit in my lights. I don't think it's a leakage problem. I stored them in an altoids tin, not near heat. I wonder if this is normal.

    Bad.... common sense. I don't know the science behind it... don't use.

    When storing batteries in a metal tin, make sure the contacts are not touching metal. Get new batteries, and give the inside of your Altoids tin a coat of Plastidip or similar.

    Do NOT attempt to recharge them again. Dispose them ASAP.

    Thanks guys! I did not know of the metal contacting would cause that. Thank so for the advice!

    Yeah metal + battery = bad. If you don't have plastidip or if thats too much hassle you can also cut a strip out of (packaging) plastic that you put all the way around inside the altoids tin nice and snug under that little rolled edge... or heck, even some isolation tape would do the trick.

    Mine have never been stored like his but some of them have similar issues. They still power my camera just fine.

    Just an FYI reminder - if you're going to line anything for carrying batteries remember that quite a few types of duct tape will conduct electricity. Electrical tape is the obvious choice.

    Can't always teach old dogs new tricks but they still know how to bite.

    Would the batteries coming into contact with each other cause a reaction like this? I was thinking of using a plastic tin that my Olight i3s came in. Unless I should wrap each battery separately.

    Only if the ends of the batteries touch each other I think. I've been using a container from a maratac aaa to hold AAAs and AAs. But then that one's to small for them to touch ends.

    A member here once posted the idea of using Silly Putty on the ends of batteries in Altoid tins. The putty provides both noise dampening and electrical isolation.

    I have also seen pictures of batteries with a friction-fitted vinyl cap over the end of the battery.
