What is an AGM Battery?

An AGM (absorbed glass mat) battery contains a special glass mat separator that wicks the electrolyte solution between the battery plates. This material's design enables the fiberglass to be saturated with electrolyte – and to store the electrolyte in a “dry” or suspended state rather than in free liquid form.

Perks: Because they do not contain a liquid that could potentially freeze or evaporate, these batteries work better in extreme climates than flooded batteries. Whether you are experiencing extremely high or low temps, AGM batteries will continue to function, even when stored in those temperatures.

AGM batteries are extremely durable, vibration resistant, and will continue to function if slightly damaged or cracked. They hold a charge even if not used regularly, making them a good solution for seasonal equipment and vehicles with batteries stored during “off-seasons.”

Pros: These batteries are referred to as maintenance-free batteries and do not require watering service. Since there is no free liquid and minimal gassing, AGM BATTERIES can perform better than flooded batteries in applications where maintenance is difficult to perform.

Cons: Users should take care when charging this battery as over, and undercharging can affect their lives and performance. AGM batteries perform most reliably when their use is limited to discharge of no more than 50% of battery capacity.
