Liebert PSA 350 Compatible Battery Kit

This replacement kit is built for the Liebert PowerSure 350 UPS (PSA350). It supplies a single 12V7A high-rate discharge SLA battery. The pack arrives factory-fresh and ready for immediate installation. It targets administrators who need a drop-in cartridge to restore runtime on an existing unit.

Thermals noise and power draw

The sealed lead-acid cell operates silently and generates minimal heat during normal float or discharge cycles. No active cooling is required inside the UPS chassis. Power draw is limited to the UPS charging circuit, which maintains the battery at full capacity without audible fan activity.

Single 12V7A high-rate discharge cell

The kit contains exactly one 12V7A battery, so it suits only UPS models that accept a single cartridge of that voltage and capacity. Systems requiring multiple cells, higher ampere-hour ratings or different voltages cannot use this pack. Buyers who need extended runtime or a different form factor should look elsewhere.

Questions about this item

How do I install the 12V7A battery cartridge in my Liebert PSA 350 UPS?

Open the UPS battery door, disconnect the old cartridge leads, connect the new 12V7A battery observing the same polarity, secure it in the compartment, close the door and allow the UPS to charge before relying on backup power.

When will the 12V7A sealed lead-acid battery need replacement again?

Expect three to five years of service; plan replacement when runtime drops noticeably or the UPS reports a battery fault during self-test.

What limits the backup time of the 350 VA UPS with this 12V7A kit during a prolonged outage?

The 12V7A capacity sets the energy reserve; once depleted the UPS shuts down, so runtime is bounded by the load you place on the 350 VA unit.
