$begingroup$ Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly. No real point in pushing it farther (and risking point 2), given that you only get a few % extra current out of it. 2) If a multi-cell battery is discharged too deeply you risk "polarity reversal" in the weakest cell.
At this voltage level, the battery can provide its maximum power capacity. As the battery discharges, its voltage will drop. For example, a battery at 50% SOC should have a voltage reading around 12.0 volts. Differentiating Battery Types. There are several types of 12V batteries, including lead-acid, AGM, and LiFePO4.
If all the acid leaked out, I would get a new battery, otherwise the acid will leak out again and possibly hurt someone or damage the vehicle. If there is no acid, certainly adding water will not help. If you do add acid, the concentration of acid needs to be correct.
