Replacement Battery Cartridge

The APC APCRBC123 is a genuine replacement battery cartridge designed for compatible APC uninterruptible power supply units. It restores backup power capability when the original batteries reach end of life. The cartridge arrives new and ready for installation.

Suitable For APC UPS Owners

This cartridge suits administrators maintaining APC UPS systems that require the RBC123 form factor. It is not intended for units that take a different cartridge number or for non-APC power protection equipment. Buyers needing a different voltage, capacity or connector should verify their UPS model before ordering.

California Prop 65 Warning Applies

The product carries a California Proposition 65 warning, indicating the presence of chemicals known to the state to cause cancer or reproductive harm. This regulatory notice is the key compliance detail that distinguishes this cartridge from batteries sold without such a warning. Review the warning if your deployment falls under California regulations.

Questions about this item

How do I install the APCRBC123 cartridge in my UPS, and what step is often missed?

Power down the UPS, remove the front panel, disconnect the old cartridge, insert the new APCRBC123, reconnect the cables, replace the panel, then power on and run a self-test to register the new battery.

What maintenance or replacement will the APCRBC123 cartridge need later?

The sealed lead-acid cells typically last three to five years; plan to replace the entire cartridge again when runtime drops or the UPS signals a battery fault.

What limit appears first on the APCRBC123 during sustained discharge?

Voltage sag under continuous load reduces available runtime before the UPS initiates its low-battery shutdown threshold.
