This is how to use jumper cables to start a car. If a car has a dead battery, jumper cables can be used to connect to a car with a good battery. In theory, the car should be able to start, thanks to the good battery in the other car. Whether or not the battery will recharge after driving is to be determined. If the battery is in good condition, the alternator may charge the battery enough while driving to eliminate the issue. My best advice is to always have a pair of jumper cables stored in the trunk, should the battery die again. #JumperCables #Cars #Howto
