AGM Batteries. Absorbent glass mat (AGM) is a class of lead-acid deep cycle battery in which the electrolyte is absorbed into a fiberglass mat. The plates in an AGM battery may be flat like wet cell lead-acid battery, or they may be wound in a tight spiral.
Maintenance free batteries are sealed for life and the water level does not need to be maintained, they are usually calcium batteries. They also have a built in hydrometer giving some indication of the charge in one cell. AGM and Gel batteries are both types of Valve Regulated Lead Acid (VRLA).AGM batteries are similar to wet batteries, except the electrolyte is being held in the glass matts, as opposed to freely flooding the plates.
