AGM batteries are often also referred to as valve regulated lead acid (VRLA) batteries, and they are often mistaken for gel batteries. AGM batteries have a low self-discharge rate of about 3% a month to start. The average lifespan of a battery using AGM technology is about 5 years, while many high-performance pure lead varieties can go much longer.
Absorbed glass mat batteries outperform most lead acid batteries when it comes to high amp loads. This is due to the electrolyte being suspended in a fiberglass matting that surrounds the lead plates. This benefit also means they can hold a higher voltage under load, while a typical lead acid battery will have a significant voltage drop. These batteries can also outperform a wet cell or gel cell battery a lower capacity levels.
