Eaton 744-A1974 - UPS Battery Pack 5 Ah
Overview
The Eaton 744-A1974 is an internal replacement battery cartridge engineered for select Eaton 9PX and 9SX series UPS systems and their extended battery modules (EBMs). IT engineers, data center technicians, and service teams deploy this pack to restore or maintain the original runtime performance of rack-mounted uninterruptible power supplies where the internal battery has aged or failed.
This cartridge consists of a sealed lead-acid (VRLA) battery pack rated at 5 Ah (5000 mAh), pre-wired for direct installation into compatible UPS chassis. It is maintenance-free and leak-resistant, designed to match the electrical profile of the OEM battery configuration, ensuring predictable runtime characteristics after replacement.
The 744-A1974 is intended for internal installation within rack UPS and EBM chassis, preserving the UPS's form factor and eliminating the need for external battery enclosures. This makes it suitable for 19-inch IDF/MDF racks, branch office network closets, and edge compute cabinets where consistent backup power is necessary.
Integration with supported UPS models leverages onboard battery management features, enabling runtime estimation and battery health reporting through the UPS interface. Hot-swappable capability permits battery replacement under load in approved models, minimizing disruption to connected servers and network gear.
In a typical field deployment, the 744-A1974 restores original runtime for a 9PX5K or 9PX6K series UPS prior to planned maintenance or before a known utility outage, ensuring mission-critical systems remain operational until orderly shutdowns complete.
This battery pack is not suitable for use outside the listed UPS series, in external battery modules not designed for internal cartridges, or in systems requiring higher-capacity battery strings for extended runtime.
