Replacement cartridge for APC SU2200XLNET

This PowerWarehouse LEADACIDSLA11-20 battery cartridge replaces the APC RBC11 unit inside the SU2200XLNET uninterruptible power supply. It uses sealed lead-acid chemistry and arrives ready to install without electrolyte handling. The maintenance-free design suits server rooms and network closets that need a direct swap for depleted cells.

Upgrade when runtime drops below acceptable levels

Replace the cartridge when the UPS reports reduced backup time or fails self-test after the typical service interval. The jump is worth it if the existing batteries no longer hold charge through expected outages. Buyers who need extended runtime beyond the original specification or a different chemistry should look at alternative UPS models rather than this direct replacement cartridge.
