PowerWarehouse LEADACIDSLA55-10 UPS Battery

This sealed lead-acid replacement battery fits the APC SUA2000 UPS and serves as a direct substitute for the RBC55 cartridge. It arrives new and maintenance-free so installers can swap it without adding electrolyte. The unit restores runtime to the original specification for critical server and network equipment.

Capacity and headroom for SUA2000 loads

The 10 Ah rating supports typical SUA2000 workloads during short outages and graceful shutdowns. Runtime drops quickly once the connected load approaches the UPS 2000 VA limit so oversized configurations will exhaust the pack faster. Buyers needing extended autonomy or higher VA capacity should look beyond this single-cartridge replacement.

Questions about this item

Will the LEADACIDSLA55-10 fit alongside the existing batteries in my APC SUA2000 without wiring changes?

The cartridge is built as a direct RBC55 replacement for the SUA2000, so it slots into the same bay and uses the original connectors.

How can I verify the LEADACIDSLA55-10 is delivering power to my SUA2000 after installation?

The UPS front panel will show a healthy battery icon and pass its self-test once the new cartridge is recognised.
