PowerWarehouse RBC48 2-pack replacement batteries

These 12 V lead-acid cartridges are built to match the original APC RBC48 specification. They ship as a matched pair so a single swap restores full runtime to the UPS. The pack suits administrators who need a drop-in refresh without sourcing individual cells.

Tool-free cartridge swap fits the original tray

Installation is a simple slide-in that requires no screws or cable splicing. The only common issue is forgetting to recycle the old sealed cells, which must go to a proper lead-acid collection point. Buyers who need a different voltage or form factor cannot use this pack.

Highlights

Questions about this item

How do I confirm the PowerWarehouse 2XRBC48SLA4811 batteries are working after installation?

The UPS should power on without a replace-battery alarm, run a self-test successfully and show normal charge status on its display.

What comes in the box with the 2-pack and what must I buy separately?

The pack includes two 12V 4811 lead-acid cartridges; no cables or tools are included, but none are required for the APC RBC48 swap.
