PowerWarehouse APCRBC123-PW replacement cartridge

This sealed lead-acid cartridge replaces Battery Cartridge #123 in compatible APC UPS units. It fits models including BN1080G, BN1250G, BN1350G, BR1000G, BR900G series, BX1000G, BX1300G, BX1350M and SMT750RM2U series. The maintenance-free design is leak proof and ready for installation.

Installing the 10.7 lb cartridge

The unit measures 6.00" L x 7.90" W x 3.10" H and slides into the UPS battery compartment. Disconnect the UPS from mains power before opening the battery door. A common issue is reversing the red and black connector leads; match colours exactly to avoid a short. Ensure the replacement cartridge sits flush before closing the door.

Sustained backup performance

The sealed lead-acid chemistry delivers steady voltage during extended outages rather than only brief spikes. Internal resistance remains stable across repeated discharge cycles. The manufacturer backs the cartridge with an 18 month warranty. Units shipped from the USA arrive ready for immediate deployment.

Questions about this item

How do I confirm the PowerWarehouse APCRBC123-PW is working after installing it in my UPS?

After installation, power on the UPS and verify the battery indicator shows a full charge; then run a self-test from the front panel or management software to confirm the cartridge delivers runtime.

What comes in the box with the APCRBC123-PW and what must I source separately?

The carton contains the sealed lead-acid cartridge (6.00" L x 7.90" W x 3.10" H, 10.7 lbs) with pre-wired connectors; no tools, mounting brackets or recycling bags are included.

Which compatible model list should I match to choose the right cartridge for my unit?

Match your UPS model against the supported list — examples include BR900G, BR1000G, BX1000G, BX1300G, BX1350M and SMT750RM2U — and confirm it replaces OEM part APCRBC123 or RBC123.
