What this battery replaces

The PowerWarehouse APCRBC124-PW cartridge replaces the OEM APCRBC124 and RBC124 units used in APC UPS models such as the BR1200G, BR1300G, BR1500G, BX1500G, BX1500M and SMC1000-2U series. It fits the same Battery Cartridge #124 slot so the swap is direct. Install it when the original pack no longer holds a full charge or when self-tests report a weak battery.

When the upgrade makes sense

If your UPS runs critical networking gear, a home server or a workstation that must survive short outages, a fresh sealed lead-acid pack restores the rated runtime. The jump is worth it when the unit reaches the typical three-to-five-year service life or when runtime has dropped below what your load requires. It is not for buyers who need a higher-capacity cartridge or a different voltage platform.

Behaviour under sustained load

The maintenance-free sealed lead-acid cells deliver steady voltage during extended discharge rather than only in brief bursts. At 11.5 lb the pack meets the original weight and dimension spec of 6.00" L x 7.90" W x 3.10" H, so heat dissipation inside the UPS chassis remains unchanged. The 18 month warranty period reflects the manufacturer's confidence in cycle life under normal float conditions.

Questions about this item

Will the 6.00" L x 7.90" W x 3.10" H cartridge fit inside my BR1500G UPS battery compartment?

The cartridge measures 6.00" L x 7.90" W x 3.10" H and is built to match the Battery Cartridge #124 form factor used by the BR1500G.

Do I need to disconnect the UPS from mains power before sliding the APCRBC124-PW into the BR1300G?

Yes — power off the UPS and unplug it from the wall before removing the front panel and swapping the cartridge.

When should I plan to replace this 11.5 LB sealed lead-acid cartridge again?

Expect a typical service life of three to five years; the manufacturer backs the cartridge with an 18 month warranty.
