The wire or wrench or anything metal conecting the two posts will get very hot fast. It may melt the wire you use. If the connection does not melt away then the battery will start getting hot and start smoking. Eventually the batter may explode or blow the top off. This is unless the battery is too discharged to generate enough heat and it will simply start cooling as it drains its energy. Dont try this at home.
