What does AGM stand for in the context of battery technology?

In the context of battery technology, AGM stands for Absorbed Glass Mat. This technology is commonly used in lead-acid batteries, particularly in deep cycle and sealed varieties. AGM batteries are designed with a fiberglass mat that absorbs the electrolyte, which enhances safety and performance. Unlike traditional flooded batteries, AGM batteries are spill-proof and can operate in various positions without the risk of leaking. They also have a lower internal resistance, which improves efficiency and allows for better performance under high-load conditions, making them suitable for applications in vehicles like the Joint Light Tactical Vehicle (JLTV).

The use of absorbing glass mat technology also contributes to the overall longevity and reliability of the battery, important factors in military applications where durability is critical. This technology typically results in faster charging times and greater resistance to vibration and temperature variations, which are essential characteristics for batteries used in rugged combat situations.
