what is agm battery

An AGM battery is a type of advanced lead-acid battery that uses a fiberglass mesh between the battery plates to hold the electrolyte in suspension and separate the positive and negative plates. The term AGM stands for Absorbent Glass Mat, which refers to the fine glass fiber separator between the positive and negative plates that helps to resist spilling acid and reduce water loss during usage. The fiberglass mat acts like a sponge with the electrolyte, making the battery non-spillable. The AGM battery technology features a high discharge rate and a wide operation temperature range, making it reliable, long-lasting, and highly resistant to vibration. AGM batteries are sealed, spill-free, and maintenance-free. They are designed to provide powerful bursts of starting amps and run electronics longer. AGM batteries are often found in high-electrical demand vehicles and seasonally used vehicles like ATVs, snowmobiles, UTVs, and powersports vehicles that require higher power, acid spillage resistance, and vibration resistance.
