Since 1987, Sun Xtender solar batteries have been hand crafted for quality in the U.S.A. Valve regulated lead acid batteries with AGM construction (VRLA-AGM) is the original AGM design adopted by the military. The maintenance free AGM design means no water replenishment - ever.
Utilizing pure lead calcium grids, the Sun Xtender battery 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 Sun Xtender Battery 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.
Sun Xtender Battery covers and containers are uniquely molded with high impact, reinforced copolymer polypropylene and are designed with thick end walls to prevent bulging. The copper alloy T Terminals are corrosion resistant and are supplied with silicon bronze bolts and washers.
All Sun Xtender Batteries ship Hazmat Exempt.
