Questions about this item

How do I verify the PowerWarehouse 2XRBC2SLA265 batteries are working after installing them in my APC BK300C?

After installation, power on the APC BK300C and check that the status indicator shows normal operation without a battery fault warning; the UPS should run a self-test and hold the connected load during a brief power interruption.

What comes in the box with the PowerWarehouse 2XRBC2SLA265 2-pack, and do I need any extra cables or hardware?

The pack includes two 12 V lead-acid battery cartridges sized for the APC BK300C; they reuse the existing wiring harness and mounting hardware, so no additional cables or connectors are required.
