Vertiv GXT5-EBC144VRT2U 144V External Battery Cabinet
Overview
The GXT5-EBC144VRT2U is a 2U rack-mount external battery cabinet designed to extend runtime on Vertiv's Liebert GXT5 UPS platform. At 81.6 lbs and a 26.8-inch depth, this is a dense, purpose-built runtime extension — not a general-purpose enclosure. It fits the same rack footprint as the parent UPS and connects without manual battery detection configuration, keeping installation straightforward in data closets and server rooms where downtime risk during maintenance is real. The GXT5-EBC144VRT2U uses valve-regulated, non-spillable, flame-retardant lead acid chemistry — the standard choice for indoor rack UPS installations where sealed battery technology is required for safety and code compliance.
Compatibility
This cabinet is compatible exclusively with two Liebert GXT5 models: the Vertiv GXT5-5000MVRT4UXLN (5kVA) and GXT5-6000MVRT4UXLN (6kVA). It is not cross-compatible with other GXT5 capacity ratings or earlier GXT generations. The parent UPS auto-detects the attached battery cabinet — no manual configuration required. Once connected, the GXT5 platform provides battery health status monitoring and replacement date prediction through its built-in UPS battery management system, which reduces guesswork on planned maintenance cycles.
Installation Notes
Rack depth requirement is 26.8 inches — verify your rack's usable depth before ordering, as shallow two-post and some four-post open-frame racks will not accommodate this unit. Operating temperature range is +32 to +104 °F (0 to 40 °C); install in a climate-controlled environment. At 81.6 lbs, proper rail and rack load planning is required — confirm your rack's rated weight capacity before positioning this unit. The cabinet occupies 2U and should be installed adjacent to or directly below the paired GXT5 UPS for clean cable routing. No external battery configuration software is required; interface is handled automatically by the Liebert GXT5 UPS firmware.
