PowerWarehouse LEADACIDSLA11-15 UPS Battery

This sealed lead-acid battery replaces the APC RBC11 cartridge number 11 inside the SU2200X106 uninterruptible power supply. It arrives new and maintenance-free so administrators can swap the module without handling electrolyte. The unit restores backup runtime for connected servers and network gear.

Sustained load behaviour

Under continuous discharge the chemistry delivers steady voltage until the cells reach their cut-off point. The maintenance-free design prevents electrolyte loss during extended cycling. Replacing the cartridge returns the UPS to its original runtime specification for the protected equipment.
