When selecting a battery type for energy storage, it’s essential to understand the differences between Gel and Absorbent Glass Mat (AGM) technologies. Both fall under the VRLA category, meaning they are sealed and maintenance-free. However, their internal designs and performance characteristics differ.
AGM batteries use fiberglass mats to absorb the electrolyte, providing better high-current performance and lower internal resistance. This makes AGM batteries suitable for applications with frequent high-power demands. On the other hand, gel batteries, with their immobilized gel electrolyte, offer superior deep-cycle durability and better resistance to over-discharge.
In energy storage systems where long-term reliability and deep discharges are common, such as in solar or wind-powered setups, gel batteries often outperform AGM batteries in longevity. However, AGMs might be preferred where faster charging and higher power bursts are needed.
