APC Back-UPS 300 compatible battery kit

This replacement battery kit is designed for APC Back-UPS 300 units and matches the APC RBC2 specification. It contains one 12V 7Ah sealed lead-acid cell and is sold new for immediate installation. Home-office users and small-business operators who need to restore runtime on an existing BK300X116 UPS will find it a direct fit.

Tool-free swap with polarity care

Installation requires only opening the UPS battery door, disconnecting the old pack and connecting the new one using the existing leads. The most common issue is reversing the red and black terminals, which prevents the UPS from starting or triggers a fault alarm. Verifying polarity before closing the door avoids a return visit. No additional hardware or firmware steps are needed.

What exactly comes in the box for the BK300X116 kit and is any extra hardware needed?

The kit includes one factory-fresh 12V 7A battery cartridge compatible with APC RBC2; no additional cables or hardware are required for installation in the Back-UPS 300.
