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.
AGM Battery | AGM Batteries | AGM Deep Cycle Batteries. AGM batteries are also known as Sealed Lead Acid (SLA) and uses the same method of gas recombination as the Gel battery so these two are often confused. The AGM (Absorbent Glass Mat) battery uses a very absorbent micro fiberglass material to trap the gas generated during discharge and recharge. The Gel battery uses a gelatin technology to similarly trap and recycle this gas internally thus both types are sealed, maintenance free and Non-Spillable.
