As the global digital landscape evolves, data centers are increasingly the foundation of modern life. Downtime is not an option. EnerSys supports your essential infrastructure with flexible, high-energy density back-up power solutions that ensure uninterrupted power to mission-critical applications. Keeping data safe and maintaining system up-time.

Data centers are evolving—scaling up, growing their workload and undertaking more multi-user hosting services. UPS are also changing— delivering shorter autonomy times to counter rising incidences of electrical failure. Both of which place new demands on the UPS battery. When there is a power outage, your UPS battery reinforces your critical infrastructure to initiate the UPS generator and ensure business continuity until it is up-to-speed. Therefore, a UPS is only as good as your batteries, the most critical component in your data center.




The changes in the data center landscape bring new challenges to overcome, including power grid instability, environmental concerns, increased demand and accessibility, pressure to reduce OPEX, and limited space on site. As they continue to play a more vital role in the global community, data center owners and operators will need to seek solutions for these dilemmas.


From new installations to upgrading legacy sites, EnerSys® continually advances our energy storage solutions to offer greater reliability, longer service life and reduced maintenance.

Next-generation Thin Plate Pure Lead (TPPL) batteries have several significant benefits. TPPL batteries operate at elevated temperatures, compared to standard energy storage products. The batteries support a much longer float life, which translates into extended service life. They also have low self-discharge characteristics, allowing them to be stored for prolonged periods of time. Meanwhile, the fast-charge capability of batteries with TPPL technology means that they can be recharged quickly and are ready to respond again within a very short period. This means they can deal with situations where multiple outages could occur. In most scenarios, the best approach will be to migrate to TPPL, with its design simplicity and operational safety advantages.
