Compatible Battery Kit for Liebert PS1500RT3120XRW

This kit supplies four 12V9A sealed lead-acid batteries built to replace the internal cells of the Liebert PowerSure 1500 UPS. It is intended for IT managers and facility technicians who need factory-fresh cells to restore runtime on existing units. The pack arrives ready for immediate installation.

Replaces aged internal batteries

When the original set no longer holds charge or self-test reports a fault, this four-battery kit restores the UPS to its rated backup capability. The upgrade is worth it whenever runtime has dropped below the level required for safe server shutdown or when preventive maintenance schedules call for fresh cells.

Straightforward swap with included instructions

Each cartridge slides into the UPS battery compartment using the existing connectors and mounting points. Comprehensive replacement instructions are supplied to guide the process. The main risk is forgetting to disconnect the UPS from mains and load before opening the battery door, which can cause a short or trigger an alarm.

Questions about this item

Will the four 12V9A batteries fit inside the PS1500RT3120XRW UPS chassis?

The kit contains four 12V9A sealed lead-acid batteries designed as direct replacements for the PS1500RT3120XRW, so they occupy the same internal cartridge space.

What is the installation step most often missed when swapping the battery cartridge?

Reconnect the battery wiring harness to the UPS terminals before closing the cover; the included instructions highlight this step to prevent a no-power condition.

When will the 12V9A batteries need replacement again under normal use?

Typical sealed lead-acid life is three to five years; plan to swap the kit again when the UPS runtime drops below your required backup window.
