using a hammer on the socket keep tapping the socket onto the nut, use a good shot of whatever pentrant you have to help, but getting it to start is half the battle, even if you twist/break off the the stud or the nut, your replacing the battery anyways, buy a new nut whan at the store.
heck, im assuming that this is a screw post terminal not a top post?? either way, tap a socket onto the nut and go for it. if its a clamp style/top post cable/connector, try using a dremel to cut the stud in between the to halfs of the connector, cover the battery to prevent sparks from possibly becoming an ignition source
