Batman verses Vader

[Nope]

I assume that the people who asked this question imagine Batman and Darth Vader to be in a neutral world where they each have only their fictional powers. If Batman could use the force then he would be a jedi without the training. He would still lose. If Vader lost the use of force, he would lose against Batman's gadgets

Without gadgets or the force, I think it would be a draw. They are both trained fighters
