I need a cover of some sort to protect a single AA or AAA battery, it cant add to the size too much but it must keep it protected, what can i use to protect them?
I use rubber caps,
here are some places that you can ask for samples from. www.harmancorp.com
.... well, crap, I dont remember the others :(
You can find them pretty easy though,
then ask for samples of the sizes you need.
I took a chapstick container for some lip gloss chapstick that was larger than a normal chapstick and tore it apart and cut it down in length and carry a nimh AA in my pocket inside of it now. Works great and takes up a small amount of room.
