SunXtender Batteries

SunXtender Batteries


Sun Xtender’s AGM design is the original Absorbent Glass Mat battery technology adopted by the U.S. Military. Deep cycle unique high density plate technology provides superior reliability, power & extended cycle life. VRLA-AGM: Valve Regulated Lead Acid Battery with Absorbent Glass Mat. The sealed, maintenance free design eliminates the requirement to monitor and replenish water levels. Low impedance design with excellent charge acceptance. There is no current limit with controlled voltage charging. Recharge is quick and complete in a minimum of time. Utilizing pure lead-calcium grids, the plates are thicker than the industry standard for longer cycle life, increased reliability and power. Sun Xtender’s proprietary Polyguard® protection is a microporous polyethylene separator used around the positive plate & AGM to prevent shorting from shock and vibration. Sun Xtender is the only manufacturer providing this added layer of protection. Shockproof high impact reinforced case restrains from bulging. Copper alloy corrosion free connections allow for maximum conductivity. Shipped fully charged and ready to install. Sun Xtender Batteries ship Hazmat Exempt.

Sun Xtender VRLA-AGM vs. Gel

Sun Xtender’s high density unique plate design with low impedance, excellent charge acceptance and retention is superior to gel batteries. Sun Xtender’s robust plates are wrapped in electrolyte absorbed AGM and packed close together. Recharging gel batteries takes longer and is impeded by the wide spaces left between the plates so the battery can be filled with thick gelled electrolyte. The gelled electrolyte is prone to solid/liquid separation at extreme temperatures and eventually during operation. This separation causes the electrolyte to lose contact with the plates, affecting battery performance and shortening battery life.
