Compatible Battery Kit for SMART550USB

This replacement battery kit is designed for the Tripp Lite SMART550USB uninterruptible power supply. It contains a single 12V7A sealed lead-acid cartridge built to match the original RBC51 specification. The kit suits administrators who need to restore runtime on an existing unit without replacing the whole UPS.

Verify UPS Model Before Ordering

Confirm that your installed UPS carries the exact SMART550USB designation before purchase. The cartridge is engineered for that specific chassis and connector layout. Using it in a different model, even within the same series, can prevent proper fit or charging.

Included Instructions Simplify Installation

The package supplies comprehensive replacement instructions that walk through the swap step by step. No additional tools or software are required to complete the change. Following the guide ensures the new battery is recognised and charged correctly by the UPS electronics.
