Compatible kit for Liebert PowerSure 500 PA500-120U

This replacement battery kit is designed for the Liebert PowerSure 500 UPS model PA500-120U. It provides a direct-fit power source for that specific unit. The kit suits administrators maintaining single-phase UPS protection in server or network environments. Installation uses the existing battery compartment without modification.

Swaps out the original 12V 7Ah cartridge

The kit replaces the factory-fitted 12V 7Ah sealed lead-acid battery when runtime has degraded or the UPS signals a battery fault. Swapping the cartridge restores the original backup duration for connected loads. The upgrade is worth it when the UPS reports end-of-life or fails a self-test. No firmware change or hardware adaptation is required.

Verify the UPS model and battery bay access

Confirm the unit is a Liebert PowerSure 500 PA500-120U before ordering; other models use different cartridges. Ensure the battery bay can be opened and the old pack removed without tools not supplied with the kit. Check that the replacement will be installed in an upright position as specified by the manufacturer.

Questions about this item

Will the 12 V 7 Ah battery fit inside the Liebert PowerSure 500 PA500-120U chassis?

The kit is built as a direct cartridge for the PA500-120U, so the single 12 V 7 Ah block slides into the original battery compartment without modification.

What is the installation step people most often miss when replacing the battery in the PA500-120U?

After inserting the cartridge you must reconnect the internal wiring harness and then run the UPS self-test to register the new battery; skipping the self-test leaves the unit reporting a fault.

How often should the 12 V 7 Ah SLA battery in this kit be replaced under normal use?

Typical service life is three to five years; plan replacement when runtime drops noticeably or the UPS signals a battery fault.
