Tell me if I did this right?
Got up today and this second battery was at 12.78. Fiddled it while watching for voltage un-sag, got it to 14.71v after an hour or so, but only taking about 1.25amps.
Figured ok clearly not full, so maybe it is desulfating. Left it going, amps increased to about 3, then decreased again. Took it off 3.5 hrs after stabilized, 4.5 hours after start.
It was still at 14.71 at the end (checked hourly), and back down to about 1.25amps. Terminals 80 degrees.
This one today, after sitting overnight, is only at 12.87. Is there anything else I can do for it?
A third battery, starting at same 12.78v, is taking 7-8 amps today.
