Compatible UPS Battery Kit

The RefurbUPS kit supplies three 6V 4.5Ah sealed lead-acid batteries designed as a direct replacement for the Tripp Lite BC400LAN UPS. It arrives factory fresh and includes comprehensive installation instructions so administrators can swap the cells without specialised tooling.

Restores Original Runtime

Replacing aged cells with this kit returns the UPS to its rated backup capacity, avoiding the shortened runtime that develops as lead-acid chemistry degrades. The jump is worth it when the existing batteries no longer hold sufficient charge to bridge typical power interruptions.

Suits BC400LAN Maintenance

This kit suits IT teams maintaining a Tripp Lite BC400LAN unit that needs a complete cell refresh. Buyers who need a different voltage, capacity or form factor should look at other replacement options.

Questions about this item

How much space do the three 6V 4.5Ah batteries need inside the BC400LAN UPS?

The kit contains three 6V 4.5Ah sealed-lead-acid cells that slide into the existing BC400LAN battery compartment; no extra mounting hardware or external space is required.

What is the installation sequence and which step is most often missed?

Power off the UPS, disconnect AC, open the front panel, unplug the old pack, insert the new three-battery kit, reconnect the pack connector, close the panel, restore AC, then run the UPS self-test — the self-test is the step users frequently skip.

When should the three-battery set be replaced again?

Plan to replace the full three-battery set when the UPS reports reduced runtime or fails its automatic self-test, typically after three to five years of normal service.
