While the plates are saturated with battery acid, an ultra-fine fiberglass mat is sandwiched between the plates, compressed, and then welded in place. The unique design of AGM batteries provides them with a higher voltage input ideal for boats, cars, golf carts, power sport vehicles, RVs, and trucks, among others.įor example, an AGM car battery offers many benefits, such as good electrical reliability and cycle life, high specific power, low self-discharge, and excellent vibration resistance.Īn AGM battery contains potive and negative lead and lead oxide plates that release electrons when they come in contact with the electrolyte (a mixture of sulfuric acid and water). A sealed lead-acid battery is also known as a VRLA battery.Īlthough sealed AGM battery technology originated in the early 1980s, it evolved further for its early uses in military aircraft applications that focused heavily on power, reliability, safety, and weight.Īs the first company to develop the AGM technology for commercial non-military use, Concorde is known for its AGM batteries referred to as VRSLAB (Valve Regulated Sealed Lead-Acid Battery) or VRLA (Valve Regulated Lead Acid). The difference lies in the addition of an ultra-thin glass mat (or AGM separator) that “absorbs” the electrolyte and makes the battery non-spillable. What is an AGM Battery? AGM Technology ExplainedĪGM batteries are based on the standard SLA (sealed lead-acid) battery construction. Keep reading to learn more about an AGM battery and how it is different from other batteries. Where traditional batteries struggled to meet the high power demands of modern vehicles or run electronic systems for a longer time, AGM batteries filled the gap as a maintenance-free, powerful alternative for a diverse range of applications.įrom powering motorcycles and submarines to everyday cars and trucks, AGM batteries are making their presence felt like never before. While a conventional battery could compete in terms of adaptability and efficiency, AGM batteries have gone a step further in redefining battery design and resilience. AGM batteries are also known as “dry,” “membrane,” or “starved electrolyte” batteries. Absorbed glass mat batteries or absorbent glass mat (AGM) batteries have gained widespread popularity in recent years.
The battery landscape is incomplete without an AGM battery.
