AGM Battery . An AGM battery is a lead-acid battery that uses an absorbed glass mat (AGM) separator between the positive and negative plates. The AGM separator absorbs and contains the electrolyte, eliminating the possibility of spillage and providing a microfiber route for electrical current that results in a very low internal resistance.
