The Vertiv Liebert GXT5 Lithium-Ion online double-conversion UPS was engineered to fully isolate critical IT from power problems. The internal lithium-ion batteries are expected to last up to three times as long as traditional valve-regulated lead–acid (VRLA) batteries, resulting in a lower total cost of ownership and, for many customers, eliminating battery replacements altogether. The UPS provides exceptional runtime on the internal battery, with up to 14 minutes of runtime at full load. Each UPS also supports up to eight external lithium-ion battery packs to extend runtime for critical operations that may require it.
