Eaton RBC93‑2U – 36 V UPS Replacement Battery Cartridge

Overview

The Eaton RBC93‑2U is a rack‑mount replacement battery cartridge designed to restore runtime in select Eaton/Tripp Lite 2U rack‑mount UPS systems whose original internal batteries have degraded below usable capacity. It is typically installed by datacenter engineers or facilities technicians responsible for maintaining UPS fleet runtime and service continuity, addressing reduced backup time due to battery aging.

This unit provides a 36 V direct‑current (DC) battery source comprised of three sealed lead‑acid (SLA) cells configured into a single cartridge. The pre‑assembled design enables rapid, tool‑free installation into UPS systems that accept this form factor without additional assembly or wiring.

Mechanically, it occupies a 2U rack height when installed and is sized to fit in compatible UPS chassis or external battery compartments intended for internal battery replacement cartridges. Weight and dimensions are aligned with industry UPS battery module form factors.

This battery module interfaces electrically with Eaton/Tripp Lite SmartPro UPS models that use a 36 V DC battery bus, such as the SMART1500RM2U, SMX1500RM2U, and SMART1500RMXL2Ua series. It must be installed according to the UPS manufacturer’s instructions to ensure proper charging and safety.

Use this cartridge to refresh or maintain full runtime capability in supported UPS deployments. It is not a standalone UPS and cannot be used in systems that require external battery cabinets with different voltage or connector standards; verify UPS compatibility before procurement.
