Bought a battery zapper/maintainer (Integy Xipp Xapper 3300) and zapped some cells last night! Read the instructions twice, was pretty confident. Powered it up and I zapped 34 3300 cells at 80volts as per the instructions.
Well, 31 of them appeared to zap no problem. 3 of them however, made a big spark and made a popping sound when I hit the zap button
The cells still read 1.2volts on the metre, so my question is: did I kill those 3 cells?
I've rebuilt them into packs and marked the ones that sparked. Instructions say not to charge them for 3 days, but I'm curious to know if I literally zapped them.
Guess the only way to know for sure is to cycle them huh? Did I zap them with too much voltage? Maybe the cells were already bad? What is the ideal voltage for 3300's? 2400's?
Thanks in advance for comments!
