Compatible Replacement Kit

This four-battery kit is built for the Liebert PS1000RT3-120XR UPS. Each unit is a 12V7A sealed lead-acid cell rated for high-rate discharge. The set arrives factory fresh and includes step-by-step installation instructions. It targets administrators who need to restore runtime on an existing Powersure 1000 unit.

Practical Limits of SLA Chemistry

Sealed lead-acid cells deliver the high surge current a UPS demands but lose capacity gradually over time. A typical service window is three to five years depending on temperature and discharge depth. The kit contains no management electronics; it relies on the host UPS for charging control and low-voltage cutoff.

Upgrading From Depleted Packs

When the original batteries no longer hold enough charge to bridge an outage, this kit restores the original runtime specification. The jump is worth it when the UPS reports a battery fault or runtime falls below the load requirement. It does not increase the VA rating or add features beyond the factory design.

Questions about this item

Should I choose the 4-battery kit or look for individual 12V7A cells?

The kit supplies four matched 12V7A batteries pre-wired for the Liebert PS1000RT3-120XR, so you replace the whole cartridge in one step without balancing cells yourself.

What does the 1000 in the UPS model mean for runtime once these batteries are installed?

The 1000 refers to the UPS power rating; with four 12V7A high-rate cells the unit delivers its rated VA for the standard load curve, giving the same runtime as the original cartridge.

Does the kit use a standard SLA interface or a proprietary connector for the Liebert PS1000RT3-120XR?

The batteries are standard 12V7A SLA blocks; the kit includes the proprietary connector harness that plugs directly into the Liebert PS1000RT3-120XR battery bay.
