PowerWarehouse LEADACIDSLA55-09 UPS Battery

This PowerWarehouse LEADACIDSLA55-09 is a maintenance-free sealed lead-acid battery built to replace the RBC55 cartridge in APC SUA3000I uninterruptible power supplies. It restores runtime for server rooms, network closets and critical workstations that rely on the SUA3000I unit. The direct-fit design lets technicians swap the cartridge without rewiring or firmware changes. Operators who need continuous uptime during mains failures will find it a practical drop-in solution.

Capacity and runtime limits

The cartridge contains 9 cells rated for the SUA3000I 3000 VA load profile, delivering the manufacturer-specified backup window for that chassis. It comfortably handles the rated load until the cells reach end-of-discharge voltage, after which the UPS shuts down to protect the battery. Runtime shortens as the cells age or if the connected load exceeds the SUA3000I rating. Buyers needing longer autonomy or higher VA capacity must look beyond this single-cartridge replacement.
