I'm targeting looking at the cells when they drop to 3.7-3.8 volt range, just being curious is all, I don't anticipate any big discoveries. Just want to compare an old tired cell against a brand new one.
It's not like the cells don't tell you when they are getting old.
They way I find the suspect ones is by going
through the rack of them with a DMM, once they build up some internal resistance, they stop holding a full charge resting. This of course, is my sign...as Larry would say...that I have way too much time on my hands
