Direct APC UPS Replacement

The BTI APCRBC105-SLA105 is a new lead-acid replacement battery cartridge designed for APC Smart-UPS rack-mount units. It serves IT managers and facility technicians who need to restore runtime on compatible SUA series systems without replacing the entire UPS. The single 12 V DC cartridge matches the original RBC105 form factor for a straightforward swap.

Restores Original Runtime

Installing this cartridge returns the UPS to its factory backup performance for connected servers and network gear. The lead-acid chemistry delivers the same voltage and discharge profile the APC electronics expect, so monitoring software and self-tests continue to report accurate health data. An 18-month limited warranty covers the replacement period.

Fits SUA2200 and SUA3000 Rack Models

This battery is validated for APC SUA2200RMXL3U, SUA2200RMXLI3U, SUA3000RMXL3U, SUA3000RMXLI3U and SUA48RMXLBP3U units. It will not fit tower-form Smart-UPS models, Symmetra frames or any non-APC chassis. Verify the exact UPS model number on the rear label before ordering.

Questions about this item

How often will the lead-acid cells in this RBC105 cartridge need replacement?

The 18-month limited warranty period indicates the expected service interval for the 12 V lead-acid pack under normal UPS cycling.

What capacity limit appears first when the SUA3000RMXL3U runs continuously on this battery?

The single 12 V DC lead-acid unit delivers finite ampere-hours, so runtime ends when the stored energy is depleted.

How much heat does the 56.4 lb cartridge add to a rack during all-day operation?

Lead-acid chemistry generates modest warmth during float charge; the mass itself acts as a thermal buffer inside the cabinet.
