Haha...a thread a newbie can definitely post in
I had charged a couple of AAs in my charger at work, and had pulled them off immediately before I left for home. I absentmindedly tossed them in my pocket, forgetting that I had about $3 in quarters jingling in there. I had no issues on the walk to the truck, the drive home, or the afternoon chores...the only time I had figured out something was wrong was when I could no longer ignore the stinging sensation on the tender part of my thigh while sitting on the bed in a bent over position, reading papers with financials on them. I was on a fairly important call for personal business and couldn't hang up, nor could I let the other party know what had happened, which was tough.
I was hopping around in the middle of the bedroom, flinging batteries, pocket change, and pocketknives everywhere in a valiant attempt to prohibit spontaneous combustion...while strenuously attempting to keep my voice calm on the phone.
It took about 5 minutes for the pocket change to cool off, a little less for my knife, but the batteries stayed warm for a while.
Needless to say I now have plastic holders for all batteries I keep in my pockets.
