I agree with Doax.

If you want to be sure, take it out and charge it with a good battery charger. Wait 3-4 hours and check the voltage.

My golf cart batteries float at 13.85 volts while the large traction batteries float at 12.75 volts. The same batteries manufactured within a few days of each other can be off by 1 or more volts. So it depends on what's normal for the battery or battery bank.

I recharge the batteries immediately when they at or below 80% of the battery capacity. That's when I see sulfation and battery capacity dwindling.
