2-pack 12 V lead-acid cartridges for APC Smart-UPS

These two replacement cartridges are built for the APC Smart-UPS 3000VA RM 120V. Each unit uses a 12 V lead-acid chemistry and carries the PowerWarehouse model reference 2XRBC11SLA1148. The pack restores runtime for rack-mount UPS units that require cartridge #11.

Compatibility limited to APC Smart-UPS 3000VA RM

The batteries fit only the APC Smart-UPS 3000VA RM 120V that calls for cartridge #11.

Questions about this item

What does the 3000VA rating mean once the battery is installed in my APC Smart UPS?

It matches the original 3000VA RM 120V UPS capacity, so runtime and load support remain identical to the factory cartridge.

What interface does the cartridge use and what does it limit in practice?

The cartridge plugs directly into the APC Smart UPS 3000VA RM 120V battery bay, limiting installation to that exact model series.
