How do I disconnect the battery?

I typed that before I took the picture. I thought it was like the gm version. It might be fine to attach there on this style. With this kind of clamp where the nut is 90° to the clamping direction the part of the fastener that re directs the force gets jammed, if you tap the stud the nut came off of down lightly it should loosen the clamp. Rotating it might help as well. As the picture sits there is nothing actively holding it on besides deformation of terminal or clamp
