Liebert PS400-60S compatible kit

This replacement battery kit is designed for the Liebert PS400-60S uninterruptible power supply. It contains one 12V high-rate discharge sealed lead-acid battery rated at 9Ah. The kit suits administrators who need a factory-fresh cartridge to restore backup runtime on an existing unit.

Sustained discharge performance

The battery uses high-rate discharge chemistry to deliver consistent current during extended utility outages. It is built to maintain voltage stability over the full discharge curve rather than only in brief bursts. Factory-fresh cells ensure the rated capacity is available from the first installation.

Straightforward cartridge swap

Comprehensive installation instructions are included to guide the replacement process. The cartridge format aligns with the original PS400-60S bay for a direct fit without wiring modifications. Verifying polarity before connection avoids the most common installation error.

Questions about this item

How much heat does the 12V 9Ah battery generate during continuous UPS operation?

The sealed lead-acid cells produce minimal heat under normal float charge; the UPS enclosure handles dissipation without extra cooling.

What existing UPS hardware is required for this replacement kit to function?

It is designed for the Liebert PS400-60S unit; the cartridge fits the original battery compartment and connects to the factory terminals.

Will the 12V 9Ah cartridge work in an older Liebert PS400-60S that has been in service for several years?

Yes, the kit matches the original voltage and capacity, so it restores runtime to factory specification in ageing units.
