Compatible Kit for Liebert PS1400RM

This replacement kit is built for the Liebert PS1400RM uninterruptible power supply. It contains four 12V7A sealed lead-acid batteries. The pack restores backup runtime for rack-mounted power protection in server rooms and network closets. It suits administrators who need a direct, factory-fresh swap without modifying the UPS chassis.

Thermals Noise and Power Draw

Each cell is a high-rate discharge SLA unit designed for steady float service inside the UPS enclosure. Normal operation produces no audible fan noise because the batteries are passive components. Heat output remains low during typical float charging and brief discharge events. The kit draws no AC power itself; it only stores energy supplied by the UPS charger.

Sustained Load Behaviour

Under extended discharge the four batteries deliver their rated capacity until the UPS reaches its low-voltage cutoff. Voltage declines gradually rather than collapsing in a short burst. The high-rate design supports the UPS inverter through long outages without premature voltage sag. Recharge time follows the UPS charger profile and is not accelerated by this kit.

Questions about this item

How do I install the four 12V7A batteries in the Liebert PS 1400RM UPS?

Power off and unplug the UPS, open the battery compartment, remove the old pack noting the wiring order, insert the four new 12V7A units in the same series string, reconnect using the included instructions, then close the cover and restart.

What replacement will the 12V7A batteries need after several years of service?

The sealed lead-acid cells will eventually lose capacity; plan to swap the full four-battery kit again when runtime drops below your required threshold.

What runtime limit appears first during a prolonged outage on the PS 1400RM?

The 1400 VA UPS will shut down once the combined 12V7A pack is depleted, so maximum backup time is fixed by that battery capacity.
