Sun Xtender® Solar Batteries: NEW Solar Battery Release!

Sun Xtender® Solar Batteries:

Concorde Battery Corporation® is pleased to introduce the following new Sun Xtender® solar batteries all of which offer Concorde's sealed, valve regulated lead acid (VRLA), absorbed glass mat (AGM) designs that have been proven and adopted by worldwide commercial and military users including the U.S., Canadian, British, Australian and Italian Air Forces. Sun Xtender® solar batteries are application design specific, engineered and produced for consistent, dependable power requirements for a given application.


The non-spillable construction allows the battery to be used upright or on its end or side and the maintenance free AGM design 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. As with the whole Sun Xtender® family, these new products feature Concorde's proprietary PolyGuard™ Microporous Polyethylene Separator that shields 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 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.

Sun Xtender® providing safe, reliable and long lasting power since 1987. Hand Crafted for Quality in the U.S.A.
