Hi: This cell reversal ability of lead acid batteries gives good perspective on just how much you can mistreat them and beat them up and still have an expectation of "recovery".
Lithium cells on the other hand without a full range of protections would have long since filled the home with all kinds of interesting high temperature thermal events, gaseous compounds and chemicals, and there is no way you could get that magic smoke back into them.

Much to my surprise the three batteries that originally registered negative voltage are now reading positive. Does this make sense - are batteries able to shift between negative and positive voltages at such a low charge level? I do not see any evidence of distorted cases.

As these are VRLA batteries, I'm curious do,the cases look damaged such as expanded or sunk in?
