XS Power AGM Batteries
XS Power AGM batteries are some of the lightest batteries on the market. Independent test results have proven that they outperform other battery models that outweigh these power providers by up to 20 lbs. Cutting-edge lead acid battery technology produces more energy in a smaller space because each cell is compressed before case insertion, resulting in efficient power-producing packages that are completely sealed with no need to ever add water. This design is ideal for the abuse, making these the batteries of choice for demanding applications who need top performance and reliability. When you are pushing to power the impossible, you need the non-stop capabilities of the XS Power AGM batteries best suited for your application. Product features include: * Designed to be an inch shorter than what the competition offers for fitting in places where space is at a premium * Deep-cycling ability and ultra-low internal resistance results in high cranking amps and excellent vibration resistance * Variable position mounting (except upside-down) thanks to the no-spill design * Offered in 6 V, 12 V, 14 V, and 16 V models
