Replacement Cartridge 143 for APC UPS

This genuine APC battery pack restores runtime to compatible Smart-UPS and Galaxy units. It ships as a single 600 Ah cartridge designed for 120 V DC output. The unit fits the listed rack-mount models without modification. Installation is a direct swap of the existing cartridge.

Hot-swap installation with safety steps

The cartridge slides into the front panel of the UPS while the load remains powered. Disconnect the old pack, connect the new one, and reset the battery-replacement date in the management card. Common issues arise when the replacement date is not updated, causing premature alerts, or when terminal connectors are not fully seated.

Suits operators of listed SMX and FJX rack UPS

This cartridge is built for the specific models shown in the compatibility list. Buyers who need a different voltage, capacity, or form factor should verify their UPS model before ordering. It does not fit tower units or non-APC systems.
