The Proper Way to Jump Start a Car

So, you think you know how to jump start a car battery? You might be surprised. The steps below outline how to properly jump start a car. Service may need to be scheduled if the car still won’t start after doing everything below.

  • The proper way to jump-start a car starts with parking the vehicle with the working battery close enough to the other car so that the jumper cables reach from one battery to another.
  • Make sure both cars are turned off.
  • Attach one red clamp to the positive (+) post on the dead battery, then attach the other red clamp positive post on the good battery.
  • Attach one black clamp to the negative post (-) of the good battery.
  • Attach the other black clamp to the metal frame of the car with the dead battery.
  • Turn on the engine of the car with the good battery. Let it run for a few minutes.
  • Try to start the other car.
  • If it won’t start, let it charge for a few more minutes, then try again.
  • After the car has started, remove the cables, starting with the black ones, then the red.
  • Don’t turn the car off right away. Let it run for a while or take it for a short drive to allow the alternator to charge the battery some more.
