Eaton RBC36‑SLT – UPS 36 V Replacement Battery Cartridge

Overview

The Eaton RBC36‑SLT is a pre‑assembled 36 V DC replacement battery cartridge for select Eaton (Tripp Lite) SLT series UPS systems. It is used by data center and network operations engineers, facilities technicians, and UPS maintenance teams to restore original runtime capability when the internal UPS batteries age or fail. This cartridge addresses the common failure mode of lead‑acid UPS batteries which lose capacity over time, ensuring continued backup power performance.

This battery cartridge comprises three sealed, spill‑proof lead‑acid (SLA) batteries wired for 36 V output, suitable for UPS systems requiring that nominal voltage. Each cell is maintenance‑free and designed to withstand typical UPS operating profiles with a service life of ~3–5 years depending on duty cycle, temperature, and discharge characteristics.

Eaton RBC36‑SLT installs into the UPS battery compartment for compatible models such as SMART1500SLT and SMX1500SLT units that use pre‑assembled battery cartridges. The pre‑wired design reduces installation time and potential wiring errors compared with individual battery replacements.

Compatibility integration depends on verifying the SLT UPS model supports pre‑assembled 36 V cartridges. Incorrect battery cartridges (different voltages or configurations) can cause UPS faults or inability to supply back‑up power. This unit does not include individual battery management electronics; battery charge and discharge behavior are governed by the UPS charger and control system.

In practice, this cartridge is replaced at scheduled maintenance intervals, during preventative service, or after a battery failure diagnosed by UPS alarms or runtime degradation. It is not intended for use in UPS systems outside the specified SLT compatibility list, and UPS units using non‑assembled battery configurations will require the appropriate individual cells.
