We need some old cells to test, I have some that have set for 2 years.
We can separate the cycling from the forced overcharge and see which actually provide benefit. My experience is that the first "wake up cycle" is always the best and then declines from there.
But, I never do a "regular cycle" like most do. I do a c/10 "charge cycle" and a very deep discharge. If one does automatic cycling by a charger one is being fooled since it is cutting off way too early at both ends.
Who would like to take the time doing a few cells? or packs? I sure wouldn't
It is really time consuming and a waste of time.
It's too bad I didn't save more graphs , but here is two such AA cells that were given to me to "fix". A graph before and after just one deadshort and formation cycle. This is as good as it ever will get. Unfortunately I do not have any pics of subsequent "cycles"
