Okay, well, let things cool down to 65 degrees F, and put on the protective gear.
The tail was still bulging, and was as hard as my ten speed tire at 60 psi.
I very slowly screwed the light apart, the seal cracked, and it hissed for quite some time.
So, what did I see?
The cell vented as it was designed to, so this isn't really considered failure. I'm *very* glad to see the battery protection mechanisms kick in like they are supposed to.
This is the same test I've tried many times on various brand cells over the past month, and this is the first time I've seen a cell vent. One of the interesting things to note, it was the 100% new cell, not the depleted one that vented- not what I expected.
I will be repeating the same test several times tomorrow, if I have time, after work.
