Vertiv GXT5-EBC72VRT2U External Battery Cabinet for 72V Liebert GXT5 UPS

The Vertiv GXT5-EBC72VRT2U is a 2U rack-mount external battery cabinet engineered to extend runtime for 3kVA Liebert GXT5 UPS systems in security headends, network operations centers, and critical infrastructure deployments. Auto-detected by compatible UPS units, this 72V VRLA battery expansion integrates seamlessly into existing power topologies without manual configuration. Intelligent battery health monitoring predicts replacement dates and flags degraded cells before they compromise runtime, giving integrators visibility into backup power readiness across distributed installations.

Key Features

• Hot-swappable, user-replaceable battery modules — no shutdown required for service
• Auto-detection by compatible GXT5 UPS units — zero manual configuration
• Intelligent battery health monitoring with replacement date prediction
• Valve-regulated, flame-retardant, non-spillable lead acid cells for safe indoor mounting
• 2U rack-mount form factor — integrates into standard 19-inch racks alongside network and recording infrastructure
• Scalable runtime extension — add multiple cabinets for longer backup windows
• Three-year advanced replacement warranty with full factory coverage
• Operating range +32 to +104°F (0 to 40°C) for IT closet and headend environments

Security and network installations demand predictable backup power. VMS servers, access control panels, PoE switches, and SIP trunks all rely on clean runtime extension when grid power fails. The GXT5-EBC72VRT2U pairs with 3kVA Liebert GXT5 UPS systems to deliver scalable backup capacity without the cost and complexity of oversized monolithic UPS units. Each cabinet houses valve-regulated lead acid batteries in a 2U chassis that mounts directly above or below the primary UPS, minimizing rack footprint in space-constrained headends and wiring closets. Auto-detection eliminates manual DIP switches or configuration menus — the UPS recognizes the expansion cabinet on power-up and adjusts runtime calculations automatically.

Battery health is the weak link in most backup power deployments. Integrators inherit installed UPS systems with unknown battery age, then discover failed cells only during the next outage. The GXT5-EBC72VRT2U communicates battery status to the host UPS, which tracks charge cycles, internal resistance trends, and temperature exposure. The system predicts end-of-life dates based on actual operating conditions rather than calendar age, so replacement budgets align with real degradation. Remote monitoring platforms can poll this data via SNMP or Modbus, surfacing battery alerts alongside camera offline notifications and disk health warnings in unified dashboards. Hot-swappable modules mean battery replacement happens during a scheduled maintenance window, not as an emergency truck roll after a power event.

Runtime extension scales with cabinet count. A single GXT5-EBC72VRT2U typically doubles or triples backup time for a 3kVA load; stacking two cabinets pushes runtime into the multi-hour range for graceful shutdowns or bridge-to-generator scenarios. Lead acid chemistry tolerates the temperature swings and infrequent cycling typical of standby power applications better than lithium alternatives at this price point, and the flame-retardant, non-spillable construction meets fire code requirements for equipment rooms without dedicated HVAC or suppression. The 72V architecture keeps current draw manageable even under heavy load, reducing I²R losses in distribution cabling and connector heating.

Vertiv's three-year advanced replacement warranty covers the battery cabinet and all internal cells, with cross-ship replacement for field-confirmed failures. For integrators managing distributed sites, that warranty posture eliminates the gray area over whether a runtime issue stems from the UPS or the battery cabinet. The GXT5-EBC72VRT2U extends mission-critical uptime for networked security infrastructure without guesswork.
