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.
The Wet comes in two styles: serviceable, and maintenance free. Gel Cell and the AGM batteries are specialty batteries that typically cost twice as much as a premium Wet Cell battery. However, Gel cell and AGM batteries do not tend to sulfate or degrade as easily as Wet Cell.hese batteries typically have a shorter life cycle than Gel Cell batteries (as much as Â½). They are often best used in applications requiring higher charge and discharge currents such as those in a UPS backup power system. The recharge voltages of Gel Cells are lower than the other styles of lead acid battery.
