What is AGM technology?

　　The structure of the absorption glass mat battery is different from that of a traditional flooded battery. But it also applies to the Sealed Deep Cycle Battery of most other brands.

　　In Sealed Agm Battery (also called starved electrolyte), a piece of ultra-fine glass fiber felt is sandwiched between the plates, which is saturated with battery acid to 95% of its capacity. Then pack the mat between the boards and compress it slightly, then solder/solder it in place. Since the plates and pads are packed fairly tightly, they are hardly affected by vibration.

　　The AGM (absorbable Glass Mat) sealed battery technology was first invented in 1980 and was developed and introduced into military aircraft in 1985, where power, weight, safety, and reliability are the most important considerations. The Concord AGM battery is VRSLAB (valve-regulated lead-acid battery), sometimes also called VRLA (valve-regulated lead-acid battery).

　　AGM-Is it a deep cycle?

　　An important thing about AGM-just because the battery is AGM does not make it a deep cycle battery. Those still have the advantages of AGM, but the cycle is not deep. The main factor leading to the deep cycle of the battery is the thickness of the plate, not whether it is full, gel, or AGM.

　　The structure of the Concorde SunXtender battery is basically the same as Concorde Lifeline, Chairman, and other Concorde AGM batteries. The main difference is that Sun-Extender batteries have bolted terminals instead of ordinary terminal types. We believe that the bolts on the terminals can provide a more reliable connection.
