Eaton BP72V18-2US – 72V 2U External UPS Battery Pack

Product Overview

The Eaton BP72V18-2US is a 72V external battery pack engineered to extend runtime on select Eaton (Tripp Lite series) rack/tower UPS systems, including the SU3000LCD2UHV and SU3000LCD2UHVTF. Built for data center, server room, and network closet deployments, this 2U rack-mount battery pack integrates directly with compatible UPS units to provide additional backup power during extended outages. Integrators sizing a UPS battery expansion for a commercial deployment can daisy-chain up to ten of these packs off a single compatible UPS for scalable runtime. The unit ships with 4-post rack-mount hardware, making it a straightforward addition to an existing rack-mount UPS installation.

Product Description

Commercial IT environments running mission-critical equipment need UPS runtime that scales with the load, not a fixed battery that eventually falls short. The BP72V18-2US external battery pack addresses that gap by adding a dedicated 72V VRLA (valve-regulated lead-acid) battery bank alongside a compatible Eaton UPS, rather than forcing a full UPS replacement when runtime requirements grow. It's purpose-built for the SU3000LCD2UHV and SU3000LCD2UHVTF UPS systems, and the included daisychain connector lets integrators add multiple packs in sequence to reach the runtime a facility actually needs. At 2U and roughly 88 lbs, it mounts into a standard 19-inch rack using the included 4-post hardware, keeping the footprint consistent with the rest of a data center or network closet rack elevation. This makes it a practical fit for facilities and IT managers planning a UPS battery expansion during a data center buildout, a server room refresh, or a network closet upgrade where downtime is not an option. Because it's a purpose-matched OEM battery pack rather than a generic replacement, it maintains the UPS manufacturer's charge and monitoring compatibility, which matters for procurement teams standardizing on Eaton power protection across a facility. The VRLA battery chemistry is sealed and maintenance-free, suitable for enclosed rack environments. Operating range is rated 0° to 40°C (32° to 104°F) with 0-95% non-condensing humidity, consistent with typical server room and data center conditions. Integrators specifying UPS runtime extension for government facilities, broadcast studios, or other always-on commercial environments can rely on this pack as a drop-in capacity add rather than a custom power solution.

Frequently Asked Questions

Which UPS systems is the BP72V18-2US compatible with?
It is designed specifically for the Eaton SU3000LCD2UHV and SU3000LCD2UHVTF rack/tower UPS systems. Confirm your UPS model number before ordering, since this battery pack is not a universal fit for other UPS series.

Can I add more than one battery pack to extend runtime further?
Yes. The included daisychain connector allows integrators to add up to 10 BP72V18-2US packs to a single compatible UPS, letting you scale runtime to match load requirements in a data center or server room deployment.

Does this battery pack include rack-mount hardware?
Yes. 4-post rack installation hardware ships with the unit, so no separate rail kit purchase is required for a standard 19-inch rack installation.

What is the battery chemistry, and does it require maintenance?
The BP72V18-2US uses sealed VRLA (valve-regulated lead-acid) batteries, which are maintenance-free under normal operating conditions.

What environment is this rated for?
It is rated for operation between 0 deg and 40 deg C (32 deg to 104 deg F) with 0-95% non-condensing humidity, which covers typical data center, server room, and network closet conditions.

What warranty coverage comes with this unit?
The BP72V18-2US carries a 2-year limited warranty from Eaton.

Do I need an electrician to install this battery pack?
Installation involves rack-mounting the unit and connecting it to the compatible UPS via the included cabling and daisychain connector. Most IT and facilities teams can complete installation without an electrician, though local code and your organization's procedures should be followed.

Is this a genuine Eaton/Tripp Lite battery pack or a third-party replacement?
This is a genuine Eaton (Tripp Lite series) external battery pack, purpose-built and matched to the specified UPS models for full charge and monitoring compatibility.
