Purpose & Fit

The APC RBC25 is a maintenance-free sealed lead-acid cartridge designed as a direct replacement for compatible Smart-UPS rack-mount units. It restores backup runtime for servers, networking gear and critical workstations in IT environments.

When to Replace

Swap the cartridge when the UPS signals a battery fault, runtime drops below operational needs or the existing pack reaches its typical service life. The leakproof suspended-electrolyte design allows safe handling during hot-swap installation without shutting down connected loads.

Capacity & Limits

Each cartridge weighs 22.80 lbs and measures 4.00" high by 10.40" wide by 6.00" deep, fitting the specified 1400 VA rack models. It supplies the rated VA runtime for the listed units only; it will not fit other UPS form factors or higher-capacity frames.

Questions about this item

Will the RBC25 cartridge fit inside my SU1400RMXL3U rack-mount UPS?

Yes, the cartridge is built for the SU1400RMXL3U, SU1400RMXLB3U, SU1400RMXLIB3U and SUA1400RMXLI3U models and measures 4.00" high, 10.40" wide and 6.00" deep.

What is the correct order for connecting the supplied cables when I swap the cartridge?

Disconnect the UPS from mains power, remove the front panel, unplug the old cartridge, attach the new connectors matching colour to colour, then reinstall the panel before restoring power.

How often should I expect to replace this sealed lead-acid cartridge?

Typical service life is three to five years; the UPS will signal when runtime drops below the 1400 VA rating, at which point the cartridge should be swapped and the old unit recycled using the included guide.
