Compatible replacement kit for OMNISMART500 UPS

This kit supplies a single 12V 7A sealed lead-acid battery built to fit the Tripp Lite OMNISMART500 UPS and match the RBC51 specification. It is intended for administrators or home-office users who need to restore backup runtime after the original cells have aged. The cartridge arrives factory fresh and ready for immediate installation.

Straightforward swap with included instructions

Installation requires opening the UPS battery compartment, disconnecting the old cartridge and connecting the new one using the existing wiring. The package includes comprehensive replacement instructions that walk through each step. The most common issue is forgetting to tighten the terminal connectors, which can cause intermittent contact and alarm beeps.

Restores original 500 VA runtime for light loads

The 7 Ah cell delivers the same capacity the UPS was designed for, supporting typical desktop, router or modem loads during brief outages. It will not extend runtime beyond the factory rating, and it cannot support heavier server equipment that exceeds the UPS 500 VA limit. For longer backup or higher power demands a larger UPS unit is required.
