Sun Xtender pioneered renewable energy storage batteries 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 AGM construction means no water replenishment ever.
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 Sun Xtender product line features proprietary PolyGuard® Microporous Polyethylene Separators, shielding the positive plates against shorting, shock or vibration. No other manufacturer offers this dual layer insulation with its effective 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
