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 Batteries: Examples and Uses

The battery is packed in a thick rubber or plastic case to prevent leakage of the corrosive sulfuric acid. The case also helps to protect the battery from damage. Working. When a lead-acid battery is charged, the lead sulfate on the plates is converted back into lead oxide and lead. This process is called "charging."

11.5: Batteries

Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.

Charging Techniques of Lead–Acid Battery: State of the Art

The chemical reactions are again involved during the discharge of a lead–acid battery. When the loads are bound across the electrodes, the sulfuric acid splits again into two parts, such as positive 2H + ions and negative SO 4 ions. With the PbO 2 anode, the hydrogen ions react and form PbO and H 2 O water. The PbO begins to react …

Tech Tip: Operating Principles for Lead Acid Batteries

The longer the lead sulfate remains on the battery plates, the more difficult it becomes to remove it. Sulfation has a cumulative effect and over time battery capacity is permanently lost. The single most significant cause for premature battery failure is a buildup of Sulfation caused by chronic under-charging of the battery bank.
