Compatible UPS Models

This replacement battery cartridge fits Eaton 9PX UPS systems rated at 3000 VA in a 2U rack form factor. It serves the 9PX3000RT, 9PX3000RTN, 9PX3000GRT and 9PX3000GLRT units. Buyers with different VA ratings or tower form factors cannot use this pack.

Hot Swap and Chemistry Limits

The sealed lead acid cells are designed for hot swappable replacement inside the UPS or matching extended battery modules. Runtime scales with load and battery age; the chemistry does not support deep cycle use or rapid recharge cycles beyond the UPS charger specification. Systems requiring lithium ion chemistry or user serviceable cells are not supported.

Installation Notes

The cartridge slides into the front battery compartment without tools and locks in place for secure contact. Common issues include forgetting to reset the battery replacement date in the UPS management software and failing to recycle the expired pack per local regulations. Units without front access panels require chassis removal first.

Questions about this item

Is the 744-A3122 the correct replacement for my 9PX 3000RT UPS?

Yes, this cartridge is designed for the 9PX3000RT, 9PX3000RTN, 9PX3000GRT and 9PX3000GLRT models, so it fits your 3kVA unit directly.

How long will the sealed lead-acid cells run my 3kVA load during an outage?

Runtime depends on the connected load and battery age; the pack restores the original backup capacity of the 9PX 3kVA UPS but does not extend it beyond the factory specification.

Does the hot-swappable design let me change batteries without shutting down the UPS?

Yes, the internal batteries and extended battery modules are hot-swappable, so you can replace this cartridge while the UPS remains online and powering equipment.
