Is 12.5 volts sufficient for battery maintenance?

I have 9 batteries. 5 are on Battery Tenders that maintain at 13.2 volts. 2 are on larger automatic chargers that maintain at 13.2 volts. The last 2 are on cheap Schumacher and Harbor Freight charger/...

Suuuuuurrrrreeeeee there is RJ,

With a tiny maintainer at capacity with a larger battery, use a digital voltmer and the second decimal column will rise a hundredth of a volt at a time. The battery is attempting to take a charge. This is a diagnostic observation.

"Ain't got no reason to try and learn me" is a classic response against education.
