How AGM Batteries Work
AGM batteries work through a chemical reaction between lead plates and sulfuric acid, releasing energy during discharge.
As you charge them, lead sulfate regenerates, ensuring efficiency and a longer lifespan.
Their design also supports deep discharge cycles without significant capacity loss, making them reliable for various applications.
Chemical Reaction Process
When you use an AGM battery, a fascinating chemical reaction takes place that powers your devices. The lead plates interact with sulfuric acid during discharge cycles, converting into lead sulfate while releasing electrical energy.
The positive plate, made of lead dioxide, and the negative plate, made of sponge lead, engage with sulfuric acid, creating lead sulfate and water. This reaction fuels your devices and showcases the battery's energy conversion efficiency.
During the charging process, the battery reverses this reaction, regenerating the lead plates and sulfuric acid, which restores its capacity for future use.
The fiberglass mat within AGM batteries immobilizes the electrolyte, ensuring ideal contact and enhancing performance through multiple discharge cycles.
Charge and Discharge Cycles
The chemical reactions that occur in AGM batteries set the stage for their efficient charge and discharge cycles.
During discharge, lead plates react with sulfuric acid, forming lead sulfate and releasing energy. When you charge the battery, this process reverses, regenerating the components for energy storage.
