Yesterday I thought of checking the micro-starter battery I keep in my truck's glove box.
It had four of five lights when I turned it on so I thought it was down a bit. The manual says that's 80 per cent charged. My voltmeter measured 11.69 volts between the terminals and that didn't seem right (but then again I'm not familiar with lithium battery characteristics).
When I went to charge it, I realized the rubber outer case didn't seem to be fitting right. I slipped it off and was astonished to find the battery had distended enough to push the black plastic inner case apart. I then realized I should also check the one in my wife's car...

You're looking at two batteries. The one on the left is the one from my truck with both the outer rubber case and the black plastic case inner removed (you can see part of the plastic one in the background).
The one on the right is the micro-starter (without its rubber case) from my wife's car.
The next photo is a taken from above the battery and I hope gives some sense of how swollen it is. The top was originally flat and about three-quarters of an inch wide with the sides dropping straight down from the edges.
