Excessive charging causes electrolysis, emitting hydrogen and oxygen. This process is known as "gassing". Wet cells have open vents to release any gas produced, and VRLA batteries rely on valves fitted to each cell. Catalytic caps are available for flooded cells to recombine hydrogen and oxygen. A VRLA cell normally recombines any hydrogen and oxygen produced inside the cell, but mal…

12V Lead-Acid vs 12V AGM Battery

First, let''s define what these batteries are. A 12V battery is a lead-acid battery that is commonly used to power vehicles and boats. It has a nominal voltage of 12 volts and is rechargeable. On the other hand, a 12V AGM battery is also a lead-acid battery, but it uses Absorbed Glass Mat (AGM) technology to hold the electrolyte in place.

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.
