Li-ion batteries deliver the same amount of energy as the valve-regulated lead-acid batteries (VRLA) commonly used with UPS systems, but with dramatically reduced weight, footprint and cooling requirements. In some data center scenarios, this means companies may no longer need separate battery rooms to house their VRLA batteries in order to keep them cooler than IT equipment needs to be.
Battery rooms are also common with respect to facility scale UPSs, including those for very large data centers, and will likely continue to be so long as they employ static UPSs associated with batteries, the most cost effective solution for short-term energy storage. But for years now, companies have been considering new architectures in order to address a number of issues.
