Cell phone battery test
Salute!
Well, I didn't die and sure enough the battery got hot.
I wimped out and cracked the case and then used a garden hose from 15 feet away ( 3 meters for you other guys).
It started to smoke about a minute into the run. And then it stopped smoking and cooled down in about 3 more minutes.
Only conclusion I can justify from the rough test is that a mechanical crack and exposure to high humidity could cause the Li-ion to get real hot. this was only a 1 amp-hour doofer, but I couldn't hold it in my hand.
Anyway, was fun to run a test, however ill-conceived and planned.
