Sun Xtender® deep cycle AGM batteries are used in a wide variety of applications to store clean renewable energy for use in lieu of conventional power sources such as generators and the traditional power grid.

Solar utility trailers use Sun Xtender® batteries to provide dependable power at construction sites and temporary concert venues where noisy, dirty generators are not an option. Oil companies in rural areas utilize Sun Xtender® batteries to harness energy from solar panels and wind turbines to power integral equipment. Road construction companies depend on Sun Xtender® solar batteries to power lighted construction signs and keep their workers safe.

The examples above highlight the versatility and rugged construction of Sun Xtender® batteries. 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.
