Compatible Kit for Belkin PRO F6C100-4

This replacement kit contains two sealed lead-acid batteries rated at 12V 18A each. It is designed for users whose Belkin PRO F6C100-4 UPS units need fresh cells to restore backup runtime. The pack includes installation instructions so the swap can be completed without specialist tools.

Dual 12V 18A high-rate discharge cells

The decisive specification is the paired 12V 18A high-rate discharge chemistry. Only batteries matching this voltage and current rating will fit the UPS chassis and meet the original runtime specification. Using a different capacity or chemistry will prevent the unit from charging or holding load correctly.

Sustained discharge keeps the UPS online

Under continuous load the high-rate discharge design delivers steady current until the inverter reaches its low-voltage cutoff. The paired cells share the load evenly, so voltage sag is minimal during extended outages. This behaviour differs from a short pulse test, which only shows peak capability.

Questions about this item

What runtime can I expect from the 12V 18Ah rating once the kit is installed in my Belkin PRO F6C100-4?

The two 12V 18Ah batteries deliver the same capacity the original unit was designed for, restoring the UPS to its factory runtime specification for connected loads.

How does the battery connector interface with the F6C100-4 and does it limit the UPS output?

The kit uses the standard terminal layout required by the Belkin PRO F6C100-4, so the UPS regulates voltage and current exactly as it did with the original batteries.

Will the two cartridges fit inside the existing battery compartment without modification?

Yes, each 12V 18Ah cartridge matches the physical dimensions of the original batteries, allowing direct replacement in the F6C100-4 enclosure.
