Keep protected workloads online longer with the Vertiv Liebert GXT5 288V EBC. Purpose-built for 8-10 kVA, 120 V GXT5 UPS environments, this external battery cabinet adds the runtime margin infrastructure teams need when utility power is unstable or outage windows run long. The 4U rack-mount form factor fits cleanly into standard IT power stacks, making it easier to scale backup capacity without redesigning the room. For data closets, edge deployments, and distributed enterprise sites, the cabinet helps preserve continuity for servers, network gear, storage, and other critical systems that cannot tolerate abrupt shutdowns. Because it is matched to the GXT5 platform, the battery cabinet is designed to integrate as part of a larger UPS strategy rather than as a generic add-on. That matters when uptime, service continuity, and orderly recovery are more important than simply adding batteries. Choose this model when you need a battery expansion path aligned to the UPS family already protecting your load.
