Eaton 744-A4311 Internal Replacement Battery Cartridge RBC
Overview
The Eaton 744-A4311 is a premium enterprise-grade internal Replacement Battery Cartridge (RBC) engineered strictly for select Eaton 1kVA online tower uninterruptible power supplies (UPS). Data center operations engineers and technical procurement teams deploy this replacement block to execute proactive maintenance cycles on aging cells, ensuring predictable runtime restoration and continuous blackout protection for critical IT assets.
The cartridge features a pre-wired, self-contained configuration housing valve-regulated lead-acid (VRLA) cells with sealed lead-acid (SLA) chemistry. This leakproof construction requires no regular fluid maintenance or technical handling, allowing safe and efficient deployment inside high-density server environments and network closets. The electrical framework supports a completely hot-swappable installation routine, enabling field technicians to safely slide out the depleted cartridge and snap in the fresh battery assembly through the front panel of the host UPS with zero interruption to connected computing equipment.
Carefully screened, balanced, and certified to original factory operational parameters, the 744-A4311 provides a steady 36V DC bus with a 9Ah capacity rating. This restores the precise chemical discharge curves needed by the host system's diagnostic firmware to ensure accurate runtime reporting. It is explicitly matched for use in Eaton 9SX1000 and 9SX1000G online double-conversion models, alongside the SU1000XLCD series equipment.
