GXT4-144VBATT Vertiv 144V RT EBC with RM Kit | UPS Battery

Add runtime where it counts with the Vertiv GXT4-144VBATT external battery cabinet. Built for compatible Liebert GXT4 UPS systems, this 144 V battery cabinet is designed to extend backup time for 5-6 kVA deployments without changing the core UPS platform. For infrastructure teams, that means more flexibility during utility events, longer windows for orderly shutdowns, and more time to bridge to generator power. The included rack-mount kit simplifies integration into rack-based environments, while the spill-proof lead-acid battery design supports dependable operation in standard IT spaces. With a 9,000 mAh battery capacity and a two-year limited warranty, this unit is positioned for organizations that want a practical runtime expansion path with clear compatibility and a known service profile. This is the kind of accessory that earns its place in a serious power architecture: not because it adds features, but because it adds time. In critical infrastructure, time is what protects transactions, sessions, and hardware. For teams maintaining GXT4 UPS deployments, this battery cabinet provides a straightforward way to increase resilience without replacing proven equipment.
