How to Jump a Car Battery?

You can jump a car battery by using another car’s battery and some jumper cables. Just make sure that you connect black to black and red to red. Also do not touch the metal portion of the cables or the battery. Always keep your hands on the rubber portion of the jumper cables. Rubber is a great insulator and it will protect you from the electricity. After they are connected start the engines. If that doesn’t work try revving the other car’s engine and start your car at the same time.
