EnerSys DataSafe XE batteriesEnerSys has presented its DataSafe XE batteries at Data Centre World this week. Specifically designed in response to the evolving requirements of modern critical UPS applications, and engineered with Thin Plate Pure Lead (TPPL) technology, DataSafe XE batteries provide high power capable of supporting short duration runtimes under five minutes.

“Changes in the datacentre industry, such as the advent of cloud storage, the shift to colocation companies and the growing trend toward modular, containerised power and a shift toward shorter runtimes have placed new demands on battery technology,” said Luca Cassani from EnerSys. “Today’s batteries must break new ground. The batteries must be capable of providing more power at shorter run times and able to operate in higher ambient temperatures, while lasting longer.”

DataSafe XE batteries with Absorbed Glass Mat (AGM) construction and TPPL technology are claimed to 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.

The batteries pack more plates into each two-volt cell, yielding greater surface area and better active materials utilisation. With this energy-dense design, 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.

“DataSafe XE batteries are specifically designed to meet the needs of the evolving data centre market,” continued Luca. “We estimate that DataSafe XE batteries can reduce the total cost of ownership by up to 25% compared to conventional VRLA batteries.”
