How bad is it to undervoltage a 12-volt lead-acid battery?
$begingroup$ 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.
Unraveling Battery Sulfation: Causes, Effects, and Solutions
A lead-acid battery is constructed from several cells. Each cell contains lead dioxide (PbO2) as the positive plate, sponge lead (Pb) as the negative plate, and an electrolyte solution of sulfuric acid (H2SO4). When the battery discharges, the lead dioxide and sponge lead react with the sulfuric acid to produce lead sulfate (PbSO4) and water.
