The DataSafe 16-V battery EnerSys provides more power in less space, easier access, and cost benefits. The revolutionary DataSafe’s 16-V UPS Battery is available in two sizes: 500 watts per cell (WPC) and 925 WPC. DataSafe 16-V front-terminated batteries require only 44 square feet to support a typical 750-kVA UPS system with a full 15 minutes of run time. The VRLA batteries used for UPS applications are designed to back-up the primary power system, typically supplying power for 15 minutes until the backup generator is fully operational. Until now, these batteries were limited to 12-V batteries.
