How to Jumpstart a Car: The Do’s and Don’ts

According to one estimate, roughly 90% of drivers have never jumpstarted a vehicle that has a dead battery. While the process might seem straightforward, you can get stumped if you’ve never actually done it before. We explain how to correctly and safely jumpstart a car.

The Step-By-Step Process of How to Jumpstart a Car

Before going through the steps, keep these points in mind: the red jumper cable is the positive; the black is the negative. The same goes for the car battery terminals. The positive terminal should have a red protective covering and the negative a black one.

The steps

  1. Clamp one end of the red jumper cable to the positive battery terminal of the dead car. Hook the other end of the cable to the positive terminal of a healthy car.
  2. Connect an end of the black jumper to the negative battery terminal of the healthy car.
  3. Hook the other end of the black jumper to a metal part of the dead car and away from the battery. 
  4. Start the good car and let idle for about five minutes.
  5. Start the dead car.
  6. Disconnect the cables in reverse order.

Do’s and Don’ts

  • If jumpstarting is unsuccessful, tow your car to an auto repair service. The issue might not be a dead battery.
  • When disconnecting the cables, make sure the clamps do not come into contact with each other.
  • NEVER connect to the negative terminal of the dead battery. This could cause an explosion.
  • Do not turn on the headlights or radio of either car during the process
