Vertiv GXT5-EBC192VRT3U 192V External Battery Cabinet
Overview
The GXT5-EBC192VRT3U is a 3U rackmount external battery cabinet designed to extend runtime on Vertiv Liebert GXT5 online double-conversion UPS systems in the 5–10kVA range. Configured for 192V DC, it uses valve-regulated, non-spillable, flame-retardant lead-acid (VRLA) cells — a battery chemistry that meets typical data center fire and transport compliance requirements without sealed-room restrictions. When the protected load demands longer holdover time than the internal UPS batteries provide — for example, a network closet sustaining a planned generator transfer or an edge compute rack riding out a longer outage — this cabinet slots into the same rack and extends that window without replacing the UPS itself. Auto-detection of external battery cabinets means the GXT5 host unit recognizes the GXT5-EBC192VRT3U on connection without manual configuration, and the UPS firmware immediately incorporates the added capacity into its runtime calculations and battery health monitoring.
Compatibility
The GXT5-EBC192VRT3U is compatible exclusively with the following Vertiv Liebert GXT5 UPS models: Liebert GXT5-5000HVRT5UXLN, GXT5-6KL630RT5UXLN, GXT5-8000HVRT5UXLN, and GXT5-10KHVRT5UXLN. Do not attempt to connect this cabinet to earlier GXT4 or GXT3 units, other GXT5 voltage configurations, or non-Liebert UPS systems — battery bus voltage and management protocol are specific to these four models. If you are deploying any of those four UPS units and need extended runtime, this is the matching UPS battery cabinet for the application. The host UPS provides battery health status readouts and replacement date prediction through its Liebert GXT5 management interface, giving you advance warning before capacity degrades enough to affect runtime commitments — relevant for data center infrastructure environments where unplanned battery replacements create maintenance windows.
Installation Notes
The cabinet occupies 3U of rack space and weighs 127 lbs fully populated — plan lift assistance and verify that your rack enclosure rail and floor load ratings support this weight before mounting. Physical dimensions are 5.1 in H × 16.9 in W × 24.8 in D; confirm rack depth clearance, particularly in shallow-depth enclosures. Operating temperature range is +32 to +104 °F (0 to 40 °C) — standard conditioned data center or IDF closet environments are within spec, but untempered spaces that exceed 104 °F will shorten battery service life. Battery interconnect and installation procedures follow the Liebert GXT5 EBC installation guide specific to the host UPS model.
