Of course, when it comes time to jump your battery, it's very important to handle the cables properly. Always keep the red and black clamps from touching, and be sure the cables stay apart when you're getting set up — especially once you have the clamps connected to a live battery. If the clamps touch when they're "hot," it could short out one or both cars and will definitely create some sparks. http://www.right-diytools.com/booster-cable/
