Jumpstart your Car: How to Boost a Car Battery Safely

One of the most common issues any car owner will face is a dead car battery. Luckily, the solution to a dead battery is straightforward – jumpstarting it, or more commonly called “boosting it”, with the help of another vehicle. This guide aims to walk you through the process of how to boost a car battery safely.

Understanding Jumpstarting – The Battery Boost
Boosting a car battery involves using a healthy car battery to provide the electrical power needed to start a vehicle with a dead battery. This process is carried out using jumper cables to connect the two batteries. We recommend keeping a set in your car’s trunk at all times. Choose cables that are thick, heavy duty, and at least 12 feet long.

Safety Comes First
1. Turn off Everything: Make sure both cars are turned off.
2. Engage the Brakes: Place both cars in Park or Neutral and engage the parking brakes.
3. Be Wary of Metal Objects: Keep any metallic objects away from the battery.
4. No Flames, Please: Do not smoke or use open flame near the battery. Batteries contain flammable gases.
5. Positive Before Negative: Remember the golden rule when connecting the cables – positive goes before negative.

Step-by-Step Guide on How to Boost a Car
1. Park the working vehicle so its battery is close to your car’s battery, without the vehicles touching.
2. Uncoil your jumper cables and separate the clamps so they don’t touch each other.
3. Locate the battery terminals marked ‘+’ for positive (red) and ‘-‘ for negative (black).
4. Attach one end of the red (positive) jumper cable to the positive terminal of the dead battery.
5. Connect the other end of the red jumper cable to the positive terminal of the good battery.
6. Connect the black (negative) jumper cable to the negative terminal of the good battery.
7. Connect the other end of the black jumper cable to an unpainted metal part on the engine block of the car with the dead battery—this grounds the circuit.
8. Start the engine of the working vehicle. Let it run for a few minutes.
9. Try starting the car with the dead battery. If it doesn’t start, let it charge a bit longer.
10. Once your car starts, disconnect the cables in reverse order: black from your car, black from good battery, red from good battery, red from your car.

What Comes Next After a Battery Boost
Keep your car running for at least 15 minutes after the boost to allow the alternator to charge the battery. If you find yourself frequently jumpstarting your car, it may be time to get professional help. Car batteries typically last 3 to 5 years.
