"EnerSys has re-designed aspects of the traditional lead-acid battery to fit it for use in datacentre UPS installations, supporting very high power density – that is, the ability to deliver all its stored energy at high current, for a short time, when required.DataSafe XE batteries are specifically designed in response to the evolving requirements of today’s modern critical UPS applications. Engineered with Thin Plate Pure Lead (TPPL) technology and superior manufacturing processes, the batteries provide high power and are capable of supporting short duration runtimes under five minutes. Changes in the datacentre industry, the company says, mean that batteries must be capable of providing more power at shorter run times and able to operate in higher ambient temperatures, while lasting longer. The construction of the batteries is key to their performance. EnerSys manufactures DataSafe XE batteries using a highly controlled grid fabrication process for maximum consistency and advanced, high purity structural and active material for optimum conductivity, electrical performance and energy efficiency. DataSafe XE batteries with Absorbed Glass Mat (AGM) construction and TPPL technology greatly reduce both grid corrosion and grid growth common in conventional alloyed Valve Regulated Lead Acid (VRLA) batteries, providing optimum conductivity and performance. The use of high purity materials also reduces gas generation within the cell. As a result, DataSafe XE batteries can operate at a higher temperature, enabling users to reduce cooling costs. The lack of impurities also improves battery shelf life by as much as four times over conventional batteries. Smaller, lighter batteries are able to achieve the same run times as larger standard VRLA batteries with reduced recharge rates. Following a full discharge, DataSafe XE batteries can achieve 100% State of Charge (SOC) in 50% less time than conventional VRLA batteries."
