But anyway, I went around and replaced batteries and had a couple of extras in my pocket, which I then transferred into my purse pocket.
Last evening at dinner out with our friend, I felt like I was sitting on a hot seat. It felt a bit like the heated seat in our new car. I wondered a bit, found my jacket that I was sitting on to be a bit warm and shifted a bit in the booth.
When we got up to leave and pay our bill, I reached into my purse pocket for my keys.
My pocket was hot. My keys were hot. I fumbled around in the pocket a bit and found:
A battery was hot! Really really hot! So hot that I would not toss it into a trashcan at that time for fear I would start a fire. (I know, you should recycle batteries.) The battery had shorted out--probably against the keychain and heated enough to melt and split the label covering and expose the bare metal casing.
It's not something that would happen every day, because how often do you toss a couple of batteries in your pocket with your keys? But be careful.
