Eaton BP36RT – 36V Extended Battery Module for SmartOnline UPS

Product Overview

The Eaton BP36RT Tripp Lite series 36V extended battery module (EBM) adds runtime capacity to compatible SmartOnline SU750RTXLCD2U and SU1000RTXLCD2U UPS systems, giving IT and facilities teams more time to ride out utility outages before a controlled shutdown. Built for rack-mount and tower installation in data centers, network closets, and server rooms, this UPS battery expansion module is a standard part of any commercial-grade power protection deployment. Integrators specifying UPS runtime extension for critical infrastructure use the BP36RT to scale backup power without replacing the primary UPS unit. It ships with rack-mounting hardware, heavy-gauge battery cabling, and a daisy-chain connector for linking additional modules.

Product Description

The BP36RT is a 36V DC extended battery module engineered specifically for Eaton's Tripp Lite series SmartOnline 2023-redesign UPS line, including the SU750RTXLCD2U, SU750RTXLCD2UN, SU1000RTXLCD2U, and SU1000RTXLCD2UN. It uses valve-regulated lead-acid (VRLA) battery technology, the same maintenance-free chemistry used in the host UPS, so runtime scales predictably as additional modules are added. For commercial deployment in a network closet or server room, the 2U rack height and included 4-post mounting hardware let the module sit directly beneath or above the UPS in a standard 19-inch rack; an optional RK2PC kit supports 2-post rack installation, and UPS support stands allow tower configuration. The daisy-chain design supports connecting up to four matching battery packs to a single UPS, which makes the BP36RT a practical building block for facilities that need to plan runtime in stages rather than over-provisioning a single large system up front. This battery module extension is a common addition when a UPS installation is protecting network switches, servers, or AV control equipment where even a few extra minutes of runtime materially reduces the risk of an unclean shutdown. Because it is purpose-built for the specific SmartOnline chassis it pairs with, the BP36RT installs using the UPS's existing battery connector and does not require rewiring or a separate charging circuit. Installation is straightforward for anyone comfortable with rack equipment: mount the module, connect the supplied high-current 36V cabling, and the host UPS automatically recognizes the added capacity. The unit operates in ambient temperatures from 32°F to 104°F (0°C to 40°C) and up to 96% non-condensing humidity, matching typical data center and network closet environmental conditions.

Key Features

• 36V VRLA Battery Architecture — Matches the host SmartOnline UPS chemistry so added modules integrate without a separate charging system.
• Daisy-Chain Expansion — Supports up to four linked battery packs per UPS, letting facilities scale runtime incrementally as needs grow.
• 2U Rack-Mount Design — Fits standard 19-inch server racks alongside the UPS and connected network or AV equipment.
• Flexible Mounting — Includes 4-post rack hardware; supports optional 2-post rack kits and tower configuration via UPS support stands.
• Heavy-Gauge Battery Cabling Included — High-current 36V DC connectors are included, simplifying installation without sourcing separate cabling.
• Purpose-Built Compatibility — Engineered specifically for the SU750RTXLCD2U, SU750RTXLCD2UN, SU1000RTXLCD2U, and SU1000RTXLCD2UN UPS systems.
• Wide Operating Range — Rated for 32°F to 104°F and up to 96% non-condensing humidity, suited to network closets and data center floors.
• Factory Warranty Coverage — Backed by Eaton's standard warranty on parts, electronics, and batteries, with extended coverage options available.

Typical Applications

• Data center rack rows requiring extended UPS runtime for compliance or SLA requirements
• Network closets supporting switches, routers, and PoE equipment during utility outages
• Server rooms where extended runtime allows for graceful shutdown of virtualized workloads
• Government and commercial facilities with critical infrastructure uptime requirements

Technical Specifications

Frequently Asked Questions

Is the BP36RT compatible with any Tripp Lite or Eaton UPS?
No. The BP36RT is engineered specifically for the 2023-redesign Eaton Tripp Lite series SmartOnline SU750RTXLCD2U, SU750RTXLCD2UN, SU1000RTXLCD2U, and SU1000RTXLCD2UN UPS systems. Confirm your UPS model number before ordering.

Can I connect more than one BP36RT to a single UPS?
Yes. The module supports daisy-chain connection of up to four matching battery packs to a single compatible UPS, allowing runtime to be scaled in stages.

What's involved in installing the BP36RT in a rack?
The BP36RT is a 2U rack-mount unit that ships with 4-post rack hardware and heavy-gauge 36V battery cabling. It connects to the host UPS's existing battery connector, so no separate charging circuit or rewiring is required. An optional RK2PC kit supports 2-post rack installation.

Does adding a battery module require reconfiguring the UPS?
No. The host SmartOnline UPS automatically recognizes the added battery capacity once the module is connected, with no manual reconfiguration needed.

What warranty coverage comes with the BP36RT?
The BP36RT includes Eaton's standard 2-year factory warranty covering parts, electronics, and batteries, with 5-year expedited parts or onsite coverage available as an upgrade.

What environmental conditions is the BP36RT rated for?
It's rated for operation from 32°F to 104°F (0°C to 40°C) and up to 96% non-condensing humidity, consistent with standard data center and network closet environments.

Will the battery module fit in a standard server rack alongside networking equipment?
Yes. At 2U and 17.3 inches wide, the BP36RT is designed for standard 19-inch racks and can be mounted near the UPS, switches, or other rack-mount IT equipment.
