Learn More$begingroup$ 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.
Learn MoreSo when we talk about a 12-volt, 24-volt or 36-volt battery, we are talking about the voltage of the devices the battery can supply power to. A 12-volt lead-acid battery that is fully charged often provides a voltage of about 12.7V. If the lead-acid battery only has 20% left, it will only deliver 11.6V.
