Why use an AGM (Absorbed Glass Mat) battery?
An AGM battery is a sealed, non-spillable maintenance free, valve regulated battery. An AGM battery utilizes a fine fiber glass material separator between the lead plates within the battery. The AGM design is also highly resistant to vibration deterioration. AGM batteries, are also called starved electrolyte they operate with no maintenance and can be installed in various ways (except upside down) without spill and provide outstanding power per dollar invested. AGM batteries are commonly interchanged with traditional flooded lead acid batteries as the charge/discharge profile of these batteries are similar. AGM batteries have low internal resistance and a very low self-discharge rate (from 1% to 3% per month). So they can sit unused for much longer periods without charging. This technology is used by Optima and Odyssey Extreme batteries for rugged applications.
