Well, F cells are the same diameter as D cells, but are about twice the length as D cells.

I took a 6V lantern battery apart once and was somewhat surprised at what I found.

This is just a guess as I don’t recall ever having seen a definition of an F-cell.  But if they were really called that, then it is a D-cell with wire leads instead of just flat contacts.
