Compatible UPS Replacement Battery Kit

This kit provides two 12V9A sealed lead-acid batteries designed for the Emerson-Liebert Powersure 1500 UPS model PSA1500MT3-120U. It restores backup power capability when the original cells reach end of life. The package includes comprehensive installation instructions for a straightforward swap. Units are factory fresh and ready for immediate deployment.

Suitable for Emerson-Liebert PSA1500MT3-120U owners

This kit suits administrators maintaining a Liebert Powersure 1500 UPS that requires a 12V9A battery pair. It is not for users whose UPS accepts a different voltage, capacity, or physical form factor. Buyers needing extended runtime beyond the standard 9Ah rating should look at higher-capacity alternatives. Those without the PSA1500MT3-120U model cannot use this kit.

Simple two-battery installation

Replacement involves opening the UPS battery compartment, disconnecting the old pair, and connecting the new 12V9A units following the included guide. The process typically requires only basic hand tools and minimal downtime. Common issues include reversed polarity connections or loose terminal fasteners, which prevent the UPS from recognising the new batteries. Verifying correct orientation before powering on avoids this problem.

Questions about this item

Does my UPS need two 12V9A batteries for this kit to fit?
