Compatible 12 V cartridge for SU1400XLTNET

This replacement cartridge fits the APC Smart UPS SU1400XLTNET and supplies a pair of 12 V lead acid units. It restores backup power for servers and network gear that depend on that UPS model. The pack contains two matched batteries for a single service visit.

Replaces depleted cartridge #11 when runtime falls

Swap the cartridge when the UPS reports reduced autonomy or fails a self test. The change is worth it if the existing set no longer holds enough charge for your load. Units that still pass self test and meet required runtime do not need replacement.

Questions about this item

Does the cartridge fit the APC Smart UPS SU1400XLTNET?

Yes, the PowerWarehouse cartridge is built to match the original RBC11 dimensions and connects directly to the SU1400XLTNET battery compartment without adapters.

What step do installers often skip when swapping the pair?

After placing both 12 V units in the tray, the connector must be pressed fully home until it clicks; a loose plug will prevent the UPS from recognising the new batteries.
