The Earth X Lithium Battery is designed to be a drop-in replacement of a standard 12-volt lead acid battery. It has four times the lifespan of a lead acid battery and weighs 70 to 80 percent less. The battery can be fully charged in less than a half hour, and the internal Battery Management System monitors each cell’s charge level, protecting them from overcharge. No special charger is required, and batteries are available for a variety of manufacturers, including Polaris, Can-Am, Arctic Cat, Yamaha, Harley-Davidson, Buell, BMW, Honda, Suzuki and more.
