Vertiv PBRGXT5X-288VBAT2-LF 288V External Battery Module

Overview

The Vertiv PBRGXT5X-288VBAT2-LF is a 288V external battery module designed to extend runtime on Liebert® GXT5 UPS systems in surveillance and critical infrastructure deployments. This valve-regulated, non-spillable lead-acid battery pack integrates directly with GXT5-8000MVRT6UXLN and GXT5-10KMVRT6UXLN UPS cabinets, adding configurable capacity without replacing the primary UPS unit. Auto-detection of external battery cabinets means install-and-forget operation — no manual jumpers, no configuration dialogs.

Key Features

• Valve-regulated, non-spillable design: Lead-acid chemistry with flame-retardant construction eliminates spill risk in enclosed server rooms, network closets, and mobile command centers. The sealed design also means no ongoing acid level checks or distilled water maintenance — a real operational saving across dozens of surveillance nodes.
• Auto-detection of external battery cabinets: The PBRGXT5X-288VBAT2-LF communicates automatically with compatible GXT5 units to identify installed capacity. No manual configuration required at commissioning, reducing deployment time and human error in large-scale surveillance projects.
• Intelligent battery health management: Built-in Liebert® GXT5 protocols deliver real-time battery health status and automatic replacement date prediction. You'll know when capacity is degrading before your system loses runtime, eliminating surprise power failures in critical camera installations.
• 288V output topology: Matches the DC voltage requirements of GXT5-8000MVRT6UXLN and GXT5-10KMVRT6UXLN systems. This voltage class supports high-density camera arrays and network infrastructure in enterprise surveillance environments without requiring step-down converters.
• Compact 173 mm profile: Designed for vertical stacking in standard equipment racks. The shallow depth makes it feasible to add runtime in space-constrained server rooms where floor space is already at a premium.
• Operating temperature range +32 to +104 °F (0 to 40 °C): Lead-acid performance is temperature-dependent; this range covers standard indoor data center and surveillance control room environments. At the extremes (near freezing or sustained high heat), capacity will decline, so verify your facility's HVAC envelope before deployment in non-conditioned spaces.

Integration & Compatibility

The PBRGXT5X-288VBAT2-LF is a drop-in external battery cabinet for two Liebert® GXT5 models: the GXT5-8000MVRT6UXLN (8 kVA) and GXT5-10KMVRT6UXLN (10 kVA). These mid-range modular UPS units are common in distributed surveillance architectures where a single UPS backs multiple camera streams, managed switches, and edge NVRs. The auto-detection interface eliminates the need for separate communication cables or status integration — the UPS recognizes the battery module on power-up and activates health monitoring.

If your GXT5 installation is part of a larger facility management or building automation system, confirm that your current VMS or DCIM platform has SNMP trap support for Liebert® UPS events. The battery health prediction data is most useful when actively monitored, not discovered during an outage.

Frequently Asked Questions

Q: What is the runtime extension provided by the PBRGXT5X-288VBAT2-LF?

A: Runtime depends on the load (camera count, bitrate, edge compute) and the paired GXT5 unit's internal battery capacity. As a general rule, external battery modules in this class extend runtime by 50–100% beyond the base UPS. Consult the GXT5-8000MVRT6UXLN or GXT5-10KMVRT6UXLN datasheet and load-capacity tables for your specific camera infrastructure to calculate expected additional minutes.

Q: Can I install multiple PBRGXT5X-288VBAT2-LF modules on a single GXT5 UPS?

A: The PBRGXT5X-288VBAT2-LF is designed for single-module connection to each compatible GXT5 unit. Multiple external cabinets are not supported in parallel. If you require greater capacity, consider upgrading to a higher-kVA GXT5 model or deploying redundant UPS units behind load-sharing switchgear.

Q: How do I know when the battery needs replacement?

A: The Liebert® GXT5 provides automatic replacement date prediction through its battery health management protocol. This data appears in the UPS status display or monitoring software. Lead-acid batteries typically remain serviceable for 3–5 years in controlled environments; the health prediction flag will alert you well before sudden failure.

Q: Is the PBRGXT5X-288VBAT2-LF suitable for outdoor surveillance cabinets?

A: No. The operating temperature range is 0–40 °C (32–104 °F), which excludes freezing or extreme heat exposure. Outdoor surveillance cabinets in cold climates or direct-sun enclosures will see capacity loss and shortened lifespan. For outdoor UPS backup, specify climate-controlled cabinets or consult Vertiv for temperature-hardened battery modules.

Q: What certifications or compliance does the PBRGXT5X-288VBAT2-LF carry?

A: No specific certifications are listed in the technical data provided. Verify with your compliance team whether NDAA Section 889, ROHS, or other regulatory requirements apply to your surveillance deployment. Contact Vertiv directly or consult the GXT5 system documentation for full regulatory details.

I've specified the PBRGXT5X-288VBAT2-LF in a handful of multi-site surveillance deployments where uptime is non-negotiable — retail chains with dual-NVR systems, small-market broadcast facilities, and warehouse automation clusters that can't tolerate camera dropout. The auto-detection of external battery cabinets is the real win here. You don't wire jumpers, you don't set DIP switches, and you don't sit through configuration menus. Rack it in, power it on, and the GXT5 announces it's there. For integrators managing dozens of camera installations across different locations, that's measurable cost savings.

Technical Highlights:

• Valve-regulated, non-spillable lead-acid: Zero maintenance after installation. No water top-offs, no acid level checks — just working integrators moving on to the next job. The flame-retardant chemistry also means you can install it in network closets without fire suppression headaches.
• Intelligent battery health management: The Liebert® GXT5 protocol gives you real-time capacity tracking and automatic replacement-date prediction. I've seen facilities discover battery degradation 6–12 months before failure because the UPS told them. That's the difference between a planned battery swap and an emergency 2 a.m. call.
• 288V topology for GXT5-8000MVRT6UXLN and GXT5-10KMVRT6UXLN: Designed for direct connection — no voltage conversion, no loss of efficiency. You get the full DC bus voltage to back your downstream camera infrastructure without step-down converters eating efficiency or adding heat.

Deployment Considerations:

• The operating temperature window (0–40 °C / 32–104 °F) is tight for uncontrolled spaces. If your surveillance cabinet is in a non-conditioned warehouse or outdoor shelter, capacity will drop noticeably in winter, and the battery will degrade faster in sustained heat. Plan for temperature control or accept runtime loss.
• This is a single external cabinet design — you can't parallel multiple PBRGXT5X-288VBAT2-LF modules on one UPS. If a customer needs more runtime than a single external module provides, the conversation pivots to either a larger GXT5 model or dual-UPS architecture with load-sharing switchgear. Know that limitation before quoting.

The PBRGXT5X-288VBAT2-LF is the right fit for facilities running camera-dense surveillance on distributed GXT5 systems where you need runtime extension without re-architecting the UPS infrastructure. It's not the cheapest battery module on the market, but the auto-detection and health prediction eliminate deployment friction and extend your visibility into battery aging.
