Vertiv™ has announced the availability of new energy storage solutions for several of its Liebert® Uninterruptible Power Supply (UPS) systems, using lithium-ion batteries from proven suppliers. Lithium-ion batteries designed specifically for UPS applications are smaller, lighter and last longer than traditional valve-regulated lead acid (VRLA) batteries, presenting an alternative for organizations seeking to leverage the benefits offered by these advanced battery technologies.
Available now in the Americas, the lithium-ion solutions are fully tested, UL listed and compatible with the Liebert NXL, Liebert EXL, Liebert NX 225-600 kVA, and Liebert Series 610 UPS systems.
Lithium-ion batteries have been commonplace in consumer electronics for decades, providing compact, lightweight, long-lasting energy storage for cell phones, laptops and tablets. More recently, those same characteristics have driven expanded applications of the technology in data centers.
The benefits are substantial. Lithium-ion batteries are considerably smaller and lighter than VRLA counterparts, significantly reducing the footprint of the battery cabinets and in some cases enabling in-row battery storage. Additionally, some lithium-ion batteries can function at higher operating temperatures than VRLA, which can reduce battery cooling costs – in some cases, by as much as 70%.
Perhaps most importantly, depending on chemistry and utilization, lithium-ion batteries can last as much as four times as long as VRLA, and routinely last two to three times as long. In most cases, VRLA batteries would need to be replaced multiple times before the first replacement of a lithium-ion battery. That’s significant when you consider the greatest cost and nuisance factor associated with UPS batteries is replacement.
Liebert UPS systems with lithium-ion batteries are available for new build, retrofit, or modular construction.
