This two-pack of 12 V lead-acid cartridges is built to fit APC RBC11 slots without modification. It serves administrators who need a drop-in refresh for existing UPS units. Buyers whose equipment requires a different cartridge number cannot use this kit.

Lead-Acid Chemistry Limits

The sealed lead-acid design delivers reliable standby power but self-discharges during long storage and loses capacity after repeated deep cycles. It is not suited for applications that demand rapid recharge or very high discharge rates.

Questions about this item

Should I choose the single cartridge or the 2-pack for my APC RBC11 UPS?

The APC RBC11 requires two 12 V cartridges wired in series; this 2-pack supplies both matched units so the UPS receives the correct voltage and runtime.

What does the 12 V rating mean once the batteries are installed in the UPS?

Each cartridge provides 12 V to the internal DC bus; connected in series they deliver the voltage the APC unit expects for normal operation and battery backup.
