The Eaton 744-A3121 is an internal battery cartridge designed to refresh select Eaton 9PX and SmartOnline UPS systems that deliver between 2 kVA and 2.2 kVA. By replacing an aging battery pack with this genuine cartridge, you bring your UPS back to its original runtime and gain confidence that it will keep servers, switches, and point-of-sale devices running through power disturbances.
Installation is straightforward. The cartridge arrives pre-wired, so you slide it into the battery bay, secure the connectors, and the UPS immediately recognizes the new pack. Because it is hot-swappable, you can perform the swap while the UPS remains energized and your equipment stays online, eliminating planned downtime and after-hours maintenance.
Reliability is built into the design. A sealed lead acid construction prevents leaks and contains the electrolyte, removing routine topping-up tasks. Each unit is factory tested and certified to meet Eaton specifications, restoring the backup capacity that was present when the UPS was new. Typical service life ranges from three to five years, and operation is approved from 32 °F to 104 °F (0 °C to 40 °C), making it suitable for temperature-controlled server rooms as well as warmer wiring closets.
This replacement cartridge is a practical choice for IT managers, network administrators, managed service providers, and anyone responsible for protecting critical loads in small data centers, branch offices, retail locations, or healthcare labs. With regulatory approvals that include UL, cUL, FCC, and CE, it slots seamlessly into compliance-sensitive environments.
