Product Identity

The RefurbUPS PowerSonic PSH 1255FR is a 12V 9Ah sealed lead-acid battery kit designed as a direct replacement cartridge for compatible UPS units. It supplies a single high-rate discharge cell to restore backup runtime in server and network environments.

Installation Experience

The package includes comprehensive UPS battery replacement installation instructions to guide the swap. The process typically requires opening the UPS chassis, disconnecting the old cell, and connecting the new unit with correct polarity. A common issue is reversed terminal connections, which can damage the UPS electronics.

Suitability Profile

This kit suits administrators maintaining UPS models that accept a 12V 9Ah PowerSonic form factor. It is not for buyers who need a different voltage, capacity, or physical size, nor for those whose UPS requires multiple batteries or a proprietary connector not matched by this single-cell cartridge.

Questions about this item

How do I verify the 12 V 9 Ah battery is working after installation?

Measure the terminal voltage with a multimeter; a reading near 12 V under no load and stable voltage during a self-test indicates the battery is functioning.

What comes in the box and what must be purchased separately?

The package includes one 12 V 9 Ah SLA battery and installation instructions; cables, mounting hardware and any UPS-specific connectors are not included.

Which version of the PSH 1255FR should I choose for my UPS?

Select the 1255FR model rated at 12 V 9 Ah; it is the only capacity offered in this series and matches the original cartridge specification.
