Engineered to meet the requirements of the power industry with its industry leading features, PowerSafe G batteries are one of the best out there. The PowerSafe G product family features calcium plates which demonstrate maximized performance in long discharge applications, allow the battery to tolerate high temperatures, and along with extra thick positive grids make the PowerSafe G family of batteries one of the most rugged on the market.
