Compatible 2-Pack for APC SU2200XL

This two-pack of 12 V lead-acid cartridges is built to fit the APC Smart UPS SU2200XL. Each unit carries the 1166 designation and is guaranteed 100 % compatible with the original equipment. The set restores backup power for servers and network gear that rely on this UPS model. Buyers needing a different voltage or form factor should look elsewhere.

Sustained Discharge Behaviour

Lead-acid chemistry delivers steady current throughout a prolonged outage rather than a brief surge. The 12 V cells maintain voltage linearly as capacity depletes, giving predictable runtime for critical loads. Recharge follows a standard constant-voltage curve after each event. Installations that demand rapid cycling or high-rate pulse power are not served by this chemistry.
