All the Spotmatics used the same 1.35V Mercury Battery. Any battery adapter or Battery that fits a Spotmatic, or a Spotmatic II, or an SP-500 or an SP-1000 also fits the Spotmatic F.
The camera will say what type it is on the front chrome, near the wind lever. If it says Spotmatic, that's what it is. If it says Spotmatic F, that's what it is, etc. etc. But ALL of them use the same 1.35V battery.
