EnerSys DataSafe XE VRLA

xe_batteryEnerSys DataSafe XE batteries by EnerSys are the first specifically designed to meet the evolving needs of today’s data center requirements. Engineered with the most advanced Thin Plate Pure Lead (TPPL) technology and superior manufacturing processes, DataSafe XE batteries support runtimes under five minutes. Longer life, lower electric spend for float and wider operating temperature range result in savings of up to 25 percent Total Cost of Ownership (TCO) compared to conventional monobloc Valve Regulated Lead Acid (VRLA) batteries.

The new EnerSys DataSafe XE range of front terminal batteries has been developed to meet the challenging demands of the modern UPS market sector. Conventional Uninterrupted Power Supply (UPS) batteries that have historically focused on a 15 minute rate discharge become increasingly ineffective in fulfilling the growing need for sub five minute autonomies. Furthermore, the pressure to lower energy costs by minimizing air conditioning in equipment rooms results in a trend towards higher operating temperatures. To meet these requirements, EnerSys has optimized its worldrenowned, advanced Thin Plate Pure Lead (TPPL) technology to deliver three front terminal monoblocs with outstanding features and benefits. Unlike typical Valve Regulated Lead Acid (VRLA) batteries, DataSafe XE provide the perfect solution to the ever-evolving requirements of today’s data center world.
