Eaton RBC64‑1U – 24 V DC UPS Replacement Battery Cartridge

Overview

The Eaton RBC64‑1U is a 24 V DC external replacement battery pack designed to refurbish the runtime capability of select rack‑mount UPS systems. It is typically deployed by data center operators, technical facilities teams, and IT engineers responsible for maintaining continuity of power protection in server rooms and network closets. The cartridge restores the battery subsystem of a UPS that has experienced end‑of‑life or degraded battery performance, ensuring continued ride‑through during mains interruptions.

Each RBC64‑1U pack consists of four pre‑assembled 6 V sealed lead‑acid (SLA) cells wired to provide a 24 V DC system voltage. The maintenance‑free, spill‑proof construction simplifies field replacement and mitigates service complexity in confined rack environments.

Mechanically, the battery cartridge occupies a 1U rack height and is intended to mount in the same rack as the associated UPS or in adjacent equipment cabinets that support rack accessories of this height. Its compact footprint minimizes the impact on usable rack space while aligning with standard server rack power infrastructures.

Integration is specific to UPS models that accept the RBC64‑1U battery cartridge. It does not provide additional electrical interfaces beyond the battery connection and works in conjunction with the UPS’s internal charging and management circuitry. Confirm compatibility with supported Eaton/Tripp Lite SmartPro UPS models before procurement.

A practical deployment scenario is refreshing battery modules in 750 VA‑class rack UPS units in branch IT racks or edge network cabinets that have entered typical end‑of‑service life (3–5 years). The RBC64‑1U enables maintenance without full UPS replacement, preserving protection SLAs and reducing capital expenditures. Environments requiring active battery monitoring, hot‑swappable multi‑pack EBMs, or integration into centralized battery health systems are not suited for this basic replacement cartridge and should consider model‑specific extended battery modules.
