Replacement Cartridge for BACK-UPS PRO

The PowerWarehouse APCRBC109-PW is a direct replacement for Battery Cartridge #109 used in APC BACK-UPS PRO BR and BX models. It fits the BR1200LCDI, BR1300LCD, BR1500LCD, BX1300LCD and BX1500LCD units. Buyers with other UPS models or those needing a different cartridge number should verify compatibility before purchase.

Sealed Lead-Acid Design with 18 Month Coverage

The maintenance-free sealed lead-acid cell is leak-proof and weighs 12 LB. It restores the original runtime for supported 1200, 1300 and 1500 VA units. Runtime will still be limited by the UPS chassis rating and load; it cannot extend backup beyond the hardware's designed capacity.

Drop-In Dimensions for Quick Swap

The cartridge measures 5.18" L x 5.95" W x 4.10" H, matching the OEM footprint for tool-less installation. Terminals align with the existing battery compartment so the swap takes minutes. Units with non-standard enclosures or modified brackets will not accept this cartridge.

Questions about this item

Will the APCRBC109-PW fit my BACK-UPS PRO BR1500LCD without modifying the battery compartment?

The cartridge measures 5.18" L x 5.95" W x 4.10" H and matches the original Battery Cartridge #109 form factor, so it installs directly into the BR1500LCD battery bay.

How can I verify the new battery is recognised and holding charge on my BX1300LCD?

After fitting the battery, power on the UPS and check the front-panel display; it should show a full charge icon and the estimated runtime for the connected load.

Does the APCRBC109-PW package include mounting hardware or cables, or must I reuse the original connectors?

The box contains the sealed lead-acid cartridge only; you reuse the existing wiring harness and mounting brackets from the old Battery Cartridge #109.
