Questions about this item

How can I confirm the 12V 21 cartridge is working after installing it in my APC BF500?

The UPS should complete its self-test and show a solid green status light; run the built-in self-test from the front panel to verify the new 2-pack holds charge.

What comes in the 2XRBC21SLA211 box and do I need any extra cables?

The box contains two 12V lead-acid cartridges numbered 21; no extra cables or connectors are required for the APC BF500 swap.
