Compatible Replacement Battery Kit

This replacement battery kit is designed for the APC Back-UPS 300 model. It contains a single 12V 7A battery cartridge that matches the original RBC2 specification. The unit is factory fresh and ready for immediate installation in compatible UPS systems.

Straightforward Installation Process

Installation typically involves opening the battery compartment, disconnecting the old unit, and connecting the new cartridge using the existing wiring.
