The battery was still warm, and each cell was still bubbling slightly
after the thing had been disconnected from the charger for about 3
hours. The SG of each cell was pretty much the same at approx. 1.1175,
and the voltage across the whole battery was 12.4. When I put it back on
charge, the voltage rose to 13.3.
What do you think?
I think the battery is bad. I may be remembering wrong, but I seem to
recall that SG should be around 1.230 for lead acid cells, I think. Also,
nominal open circuit voltage on a freshly charged battery ought to be at
LEAST 12.8 volts.
