Questions about this item

Does the RBC55 cartridge use a standard 24 VDC SLA interface that caps run time at 30 minutes?

Yes, it supplies 24 VDC from four 12 V 18 Ah modules and the listed run time is 1 to 30 minutes depending on load.

What are the exact dimensions of each module so I can confirm it fits my UPS chassis?

Each of the two modules measures 7.20 inches by 6.80 inches by 5.60 inches.

How is the cartridge installed and what step do people often miss?

Power off the UPS, remove the front cover, slide out the old cartridge, insert the new modules in the same orientation, reconnect the wiring harness, replace the cover, then run the UPS self-test to register the new batteries.
