The RefurbUPS Briggs & Stratton B4489GS kit supplies a single 12V 18A sealed lead-acid battery for standby power units. It is intended for administrators maintaining compatible UPS systems that require a direct cartridge swap.

Compatibility and Installation Checks

Verify that the existing UPS accepts a 12V 18A cartridge with the B4489GS form factor before ordering. Confirm the unit’s voltage and ampere-hour rating match the replacement, and ensure the installation instructions supplied with the kit align with your hardware revision.

Upgrade From Depleted or Ageing Cells

This kit replaces a worn or failed 12V 18A battery inside a supported UPS, restoring runtime to factory specification. The jump is worthwhile when the original cell no longer holds charge or when preventive replacement is due per the manufacturer’s service interval.
