What causes sulfation in lead-acid batteries?
Low charge levels can also contribute to sulfation in lead-acid batteries. When a battery is not fully charged, the lead sulfate crystals that form during discharge can become larger and harder, making it more difficult to remove them during the charging process. Over time, this buildup can lead to reduced battery performance and a shorter ...

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.
Lead–acid battery
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté is the first type of rechargeable battery ever created.
