Tripp Lite BC425FCB compatible battery kit

This replacement kit supplies three 6V12A sealed lead-acid batteries built for the Tripp Lite BC425FCB UPS. It restores backup power for servers, network gear and workstations that depend on continuous uptime during mains failures.

Verify the UPS model before ordering

Confirm the unit is a Tripp Lite BC425FCB and that it currently uses RBC52 cartridges. The kit includes installation instructions, but the UPS must be powered down and disconnected from the load before the batteries are swapped.

Direct swap for depleted RBC52 cartridges

The package replaces the original three-battery set when runtime has fallen below acceptable levels. The jump is worth it when the UPS self-test fails or when the existing pack can no longer hold the connected equipment through typical outages.

Questions about this item

Does the kit include everything needed to replace the batteries in my BC425FCB UPS, or must I buy cables or trays separately?

The kit supplies three 6V 12Ah sealed lead-acid batteries that match the original RBC52 specification; no extra cables or trays are required for the swap.

Should I choose this 425FCB kit or the 420FCB version for my UPS?

This kit is built for the BC425FCB model; the 420FCB kit fits a different UPS, so select the one that matches your exact unit.

What does the 12Ah rating mean for actual backup time once the batteries are installed?

Each 6V 12Ah cell delivers the same capacity as the factory pack, restoring the UPS to its original runtime at a given load.
