Compatible replacement kit

The RefurbUPS kit provides a direct replacement cartridge for the Tripp Lite SM550UNAFTA UPS. It contains one 12V 7A sealed lead-acid battery built for high-rate discharge. Factory-fresh cells and included installation instructions let technicians restore backup power quickly. The package suits IT teams maintaining existing Smart Series UPS units.

Single 12V 7A cell capacity

One 12V 7A battery supplies the rated runtime for the SM550UNAFTA under typical loads. The high-rate discharge design supports the UPS during short outages and voltage sags. Runtime scales with connected load, so heavier equipment will exhaust the reserve faster. The kit does not add extra cells or increase the original capacity.

Form-factor and voltage constraint

The cartridge fits only UPS models that accept the RBC51 form factor and 12V nominal voltage. Systems requiring a different voltage, higher amp-hour rating or multiple batteries cannot use this kit. Buyers needing extended runtime or a different connector layout must select an alternative solution.
