Eaton Internal Replacement Battery Cartridge (RBC) for 9SX1000, 9SX1000G, and SU1000XLCD UPS Systems

The Eaton 744-A4311 is an internal replacement battery cartridge made specifically for the Eaton 9SX1000, 9SX1000G, and SU1000XLCD UPS systems. Installing this cartridge restores the unit’s original runtime, so your connected equipment keeps the same level of protection it had when the UPS was new.

Because the cartridge arrives pre-wired and hot-swappable, you can replace the old battery while the UPS is running. There is no need to shut down servers, network switches, or any other devices that rely on constant power, which makes the swap an easy task for IT staff who cannot afford downtime.

The sealed lead acid construction creates a battery that is leakproof and requires no ongoing maintenance. A wide operating temperature range means the cartridge performs reliably in server closets, small data centers, medical workstations, or home labs where ambient conditions can fluctuate.

Whether you manage a branch office rack or protect sensitive electronics at home, keeping a fresh battery on hand ensures your UPS will handle unexpected outages without hesitation. Installing the Eaton 744-A4311 is a straightforward way to preserve uptime and protect critical data.
