Spare S3 battery case or holder?

[sonnythemoney]

I am looking for a solution for carrying a spare regular S3 battery. I would like to be able to carry it in my pocket, in a small plastic case that is not bulky. Has anyone found such a case? I don't want to chance shorting the battery with coins or keys. My spare battery for my Blackberry came with a small case for it. Even if anyone has found something that fits well, like an old mint or gum case etc. It would just make me feel better. Not to mention if the battery ever leaked etc. Any help would be most appreciated.

Man i had this idea years ago to make like a keychain with a thick rubber-type socket that you can stick the contacts end of a phone battery into but im a lazy lazy guy
P.s, dont worry about it leaking, its not like a car battery. Even if it got shorted, it would take a sustained time to do any kinda damage :thumbup:
