The Battery Council International (BCI) defines AGM batteries as a type of lead-acid battery that uses fiberglass mats to absorb electrolyte. This design allows the electrolyte to remain suspended, which contributes to the battery’s efficiency and durability.

AGM batteries are favored because they offer several advantages over traditional flooded lead-acid batteries. First, they are spill-proof, making them safe to use in various orientations. Second, they have a lower self-discharge rate, which means they can hold charge longer when not in use. Third, they provide better vibration resistance, which is essential for applications in vehicles and equipment.

The technical term “self-discharge rate” refers to the rate at which a battery loses charge when not actively in use. AGM batteries typically maintain around 3-5% self-discharge per month, while traditional batteries may lose 15-20% monthly. This makes AGM batteries more reliable for applications such as solar energy storage and backup power systems.

The mechanisms behind the performance of AGM batteries include their valve-regulated design and the use of absorbed electrolyte. The fiberglass mats allow for better electrolyte retention and minimal evaporation. Additionally, AGM batteries have a lower internal resistance, which enables them to deliver higher currents rapidly, making them suitable for demanding applications like starting engines or powering high-drain devices.

Specific conditions that favor the use of AGM batteries include environments where spills could be hazardous, such as on boats or in machinery. They are also ideal for situations requiring frequent cycling, such as in renewable energy systems.
