It cannot be used. This is a charger for Fujifilm cameras. It needs to be used for special models of cameras. 

These NP-FZ100 battery packs are compatible with Sony A7 III, A7 IV, A7RIII. Not suitable for Nikon cameras. 

Hi. Yes it is suitable , in fact , that's the very camera I'm using it on. It rather depends what you mean by 'fully'. The camera will not use any of it's auto features because the lens is totally manual , there is no metering and also the focus aids don't work. However , the camera takes pictures with a tamron lens perfectly well . Set it to 'M' on the dial and then set your own shutter speed and aperture . It will look a little dark through the view-finder ( at least it does on my 135 telephoto lens ) but the pictures come out fine . 

If you plan to shoot during bright sunny days it is absolutely necessary. Its will save your highlights and let you open the lens to its widest aperture to get nice bokeh. 

Yes, it is indeed Nikon f mount.
