Questions about this item

Will the 8.86" x 7.24" x 3.78" cartridge fit inside my SMT750RM2U rackmount UPS?

Yes, this APCRBC123 cartridge is the direct replacement for the SMT750RM2U and the other listed Smart-UPS and Back-UPS Pro models.

How do I install the hot-swappable battery without shutting down my connected equipment?

Remove the front bezel, disconnect the old cartridge, slide the new one in until it clicks, reconnect the wiring harness, and replace the bezel — power stays on the whole time.

When should I plan to swap out this maintenance-free sealed lead-acid cartridge?

The expected service life is 3 to 5 years; replace it once the UPS reports a battery fault or runtime drops noticeably.
