PowerWarehouse 12V UPS battery pack

This two-pack of 12V lead-acid batteries replaces the original cartridge in a Belkin F6C650-USB-MAC uninterruptible power supply. It is built for administrators who need a direct, drop-in swap to restore runtime on that specific model.

Guaranteed compatibility restores full UPS function

The batteries are tested for 100% compatibility with the F6C650-USB-MAC, so the UPS resumes its original charge cycles and monitoring without firmware changes. Buyers who need a different form factor, voltage, or a higher capacity cartridge will need a separate part number.

Questions about this item

How often should the 12 V lead-acid cells in this 2-pack be replaced under normal UPS duty?

Plan on swapping both cartridges every three to five years; the sealed 12 V design is maintenance-free until capacity drops below useful runtime.

What runtime limit appears first when the Belkin F6C650-USB-MAC runs on battery during a prolonged outage?

The 650 VA UPS will hit its amp-hour ceiling first; once the two 12 V packs are depleted the unit shuts down to protect the cells.
