VRLA-AGM Deep Cycle Battery for Off Grid and Grid Tied Systems.
Since 1987, Sun Xtender has been designing valve regulated lead acid batteries with AGM construction (VRLA-AGM).The non-spillable construction mean no water replenishment ever and allows the battery to be used upright, on its end or on its side. Reference the Technical Manual for Sun Xtender® Batteries for installation and operation information.
Utilizing pure lead calcium grids, the plates are thicker than the industry standard for longer cycle life, increased reliability and power. The low impedance AGM design allows for excellent charge acceptance and there is no current limit required with controlled voltage charging.
The whole Sun Xtender product line features proprietary PolyGuard® Microporous Polyethylene Separators, shielding the positive plates against shorting, shock or vibration. No other manufacturers offer this dual layer insulation protection feature.
