I thought it would be interesting to compare the insides of different NiMh cells. Low capacity, high capacity and low self discharge.
I thought that discharging the cells completely would avoid little unexpected combustion incidents.... I was wrong.
The keyword here is pyrophoric. On a plus note my bench is a lot tidier now that I've cleared it enough to find all the little incendiary bits that had pinged in amongst the stuff.

For those who enquired about the cell weights, I've weighed their partner cells and the results are:
Eneloop 25.85g
LIDL 2500mAh Tronic 27.76g
Generic 600mAh 12.5g
