Compatible UPS Models

The PowerWarehouse RBC24-PW cartridge replaces Battery Cartridge #24 in a wide range of APC Smart-UPS units including the SU1400RM2U, SUA1500RM2U and SUA1500RMI2U series. It is built for IT managers and facility teams who need a drop-in replacement to restore runtime on existing rack-mount UPS systems.

Sustained Load Behaviour

The maintenance-free sealed lead-acid design delivers steady voltage during extended discharge rather than only short bursts, supporting critical loads until mains return or graceful shutdown completes. Leak-proof construction allows horizontal or vertical mounting inside the UPS chassis without risk of electrolyte escape.

Practical Interface Limits

The cartridge uses the standard Battery Cartridge #24 form factor and connector layout, so it fits only UPS models listed in the compatibility data. It cannot be used in units that require a different cartridge size, voltage or terminal arrangement. Buyers needing higher capacity or a different form factor must select an alternative cartridge.

Questions about this item

Does the sealed lead-acid RBC24-PW generate noticeable heat or noise during continuous UPS operation?

The maintenance-free sealed lead-acid design has no moving parts, so it runs silently and adds only normal battery warmth inside the UPS enclosure.

Which UPS chassis must I already own for this cartridge to fit and connect?

It fits APC Smart-UPS models such as SU1400RM2U, SU1400RM2UX93, SU1400RMI2U, SUA1500RM2U and the listed SUA1500R2X variants.

Will the 13.50" L x 8.50" W x 3.25" H cartridge align with the battery bay rails on an older SU1400RM2U unit?

Yes, the dimensions match the original Battery Cartridge #24, so it slides into the same bay and uses the existing connectors.
