Compatible replacement for APC SC450R1X542 UPS

This two-pack of PowerWarehouse 6V lead-acid cartridges is built to match the original equipment specification for the APC SC450R1X542 uninterruptible power supply. Each unit carries the model reference 2XRBC18SLA189 and is supplied new. The pack is intended for administrators who need a direct swap to restore runtime on compatible APC hardware.

Capacity and headroom for SC450R1X542 units

The pair replaces the factory cartridges numbered 18 and 189, delivering the rated voltage and chemistry the UPS expects. They support the 450 VA and 542 W ratings of the host unit, so typical server and network loads are covered until the cells reach end of life. Buyers who need extended runtime beyond the standard cartridge capacity or who operate a different UPS form factor will need a higher-capacity or alternative-model solution.

Questions about this item

Will the 2XRBC18SLA189 cartridge fit inside my APC SC450R1X542 UPS without modification?

The cartridge is guaranteed 100% compatible with the APC SC450R1X542, so it installs directly using the original battery compartment and connectors.

How can I verify the 2XRBC18SLA189 pack is delivering power correctly after installation?

After fitting both 6 V lead-acid cells, run a self-test from the UPS front panel or management software; a passed test and normal runtime confirm correct operation.
