I can see a woman having no problem whatsoever with a 4.1" girth. Hell, my girl uses the handle (and sometimes bristles) of a toothbrush to masturbate, and she's able to cum from it very nicely.
Though she prefers a fat cock to a thin one, and she's very stretchy girthwise, 4.1" would definitely be an adequate girth to get her off. And when I say "very stretchy", I mean I'm able to stick both my entire left hand and 3 fingers from my right hand inside of her (and one time, the bottom of a Poland Spring bottle). We're talking 8-9" girth here, people. Yet the thin little toothbrush, with some skill, still suffices when I'm away.
So I'm not sure if a D battery could be called "ideal", but it can definitely be called adequate.
