Want to ask the list for some help.
I have a 12V battery of which one cell has been reversed
(likely multiple times) because it was the first thing to go
when the rest of the cells were still going strong.
I drilled a hole in the top of this battery and found that
one cell was going to 0V while the others were still above 2.1V
under 30A load, so the inverter (which I used to test it) did
not cut off its load (10.5V LVD) before that first cell was
entirely reversed and started in the negative voltages.
I have tried watering that cell and recharging it separately
but it looks like it does not hold much charge, therefor it
goes flat as the first of battery.
Is there anything that I can try to regain capacity?
This is an AGM battery and I went as far as squirting enough
water in the cell that it became a flooded cell (which I am
now converting back to AGM by continuous over-charging at
a slow pace so the redundant water will dissolve as H2 and O2
All of my actions have shown a reduction of capacity or at best
no effect, so I am either going to toss it (likely first saw it
open to inspect it and see if I can find why its capacity has
been so reduced) or need to find a means to restore it to
(I hate to toss anything that should not be halfway its useful
life by now)
Any suggestions appreciated.
