Compatible UPS Replacement Battery

This battery cartridge is built for the Tripp Lite SM550UNAFTA UPS and matches the RBC51 form factor. It supplies a single 12V7A sealed lead-acid cell that restores backup runtime after the original pack wears out. The unit arrives factory fresh and ready for immediate installation.

Simple swap for continuous protection

The cartridge slides into the UPS without tools and requires no firmware updates or extra wiring. It frees the UPS to resume guarding connected equipment against outages and voltage fluctuations. Builders who need extended runtime beyond one cartridge or a different voltage platform should look elsewhere.
