I had the not so bright idea of wrapping my batteries in cellophane
wrap when installed in devices that I care about (Geiger counters,
instruments, test equipment, emergency radios, GPS, etc). The problem
was that the batteries usually leak from the end terminal area, which
cannot be covered with cellophane wrap. Oops. My next attempt will
probably be to add a sponge at both ends of the battery (with a hole
in the center for the connection). The plan is to localize the
damage, not prevent it. Maybe seal the battery compartment.

Unless they are flashlights and you need to turn them on to see them,
then why not just wrap the batteries in ziplock bags? Or if you have a
vacuum sealing machine, one of their bags?

When I was traveling, I had a suitcase packed and in it a kit with various
things I would want, such as an electric kettle, a small portable radio,
a flashlight (so that I was not stuck in the dark in a strange place
because I did not know where the light switch was) and so on.

I was careful to choose devices that used the same batteries, and keep them
in a ziplock bag. In order to not have to go searching for them, I kept
the devices and the bag of batteries all in one larger ziplock bag.

At one time I had a cellphone that used AA cells but that was a long time
ago. I don't think you can get one now.

About six months ago I replaced the D cells in my backup AM/FM home radio
(a GE SRIII) with AA cells in adaptors. Last week I took them out. They
did not leak, but one of them was was swollen enough I had to push it out.
