You know how frustrating it can be to find yourself stranded with a car that won't start. One cause of a vehicle not starting is a dead battery. Fortunately, you can often jump-start a dead battery and get your car running again.  

You’ll need another car with a healthy battery or a battery jump starter. You can call CAA for roadside assistance if you don't have access to either. 

Before we get into the step-by-step process, it's important to note that jumping a battery can be dangerous if not done correctly. Follow all safety precautions, such as wearing protective eyewear and gloves, and carefully read your vehicle's battery jump starter instructions. 

Here's how to jump-start a dead battery:

1. Position the two cars so that they are facing each other, with the hoods open. 

2. Locate the batteries in both cars. In most cases, the battery is under the hood, near the front of the vehicle. 

3. If using another car to jump-start your battery, ensure that the assisting vehicle's engine is off and the transmission is in park. 

4. Connect the positive (red) jump leads to the positive terminal of the dead battery and the positive terminal of the assisting battery. Then, connect the negative (black) jump leads to the negative terminal of the assisting battery and a metal surface on the car with the dead battery (such as a bolt on the engine block). 

5. Start the assisting car and let it run for a few minutes. 

6. Try starting the car with the dead battery. If it starts, remove the jump leads in the reverse order that you attached them (first the negative, then the positive). 

7. If the car with the dead battery won't start, another issue could be at play. In this case, it's best to consult a mechanic or a jump-start car service for further assistance.
