Are 'dead' batteries really dead or just absent of a measurable positive charge?
I spent the better part of 5 days making sure that a heavily sulfated battery (85Ah) had little to no positive charge. I left a load connected for days. It wouldn't even light a red LED, which only takes a volt or two to light.
I used this battery in the David Bowling setup with three batteries (as noted in that thread).
Upon cleaning up and closing the book on the experimental setup I noticed one very anomoulous thing. One of the 12v 7Ah batteries had switched polarities. The other 12v 7Ah battery was charged to 13.8v (started at 12.12v).
First I can't say that I have EVER experienced a battery switching polarites.
I tried to kill the 12v 7Ah switched polarity battery through time loads, and I got it down to fractions of a volt (standing voltage). I put it on my TRex 30 Amp battery charger only to blow the breaker several times. So I thought, maybe its shorted out? I could produce no evidence for that.
So I let it set and it returned by itself to -11.6v opposite polarity. I said ok and put it back on the TRex charger (matching opposite polarity) and it charged to -14.5v. I did a series of load test and it seems absolutely as robust as all of the other 'normal' batteries.
I had used this battery prior in many other setups and never had an issue. Until it interacted with the 12v 85Ah marine battery.
Back to my initial question. Are dead batteries really dead, or might they have some other kind of yet undiscovered purpose... example: ground charge buffer, cold electric capacitor, negative frequency sink, etc?
Thoughts?
