Questions about this item

Will the 24 V lead-acid cartridge #33 fit alongside the original APC BR1100CI-AS electronics?

Yes, the 2-pack is built to match the factory cartridge #33 specification so it installs directly into the BR1100CI-AS without any adapter or wiring changes.

How can I confirm the 24 V cartridge #33 is delivering full runtime after installation?

Run a self-test from the UPS front panel or management software; a passed test and the expected runtime shown for the BR1100CI-AS indicate the replacement set is working correctly.
