Jumpstarting Dos and Don’ts: Avoid Common Mistakes

Jumpstarting a vehicle is a common task that many drivers may find themselves faced with at some point. Whether it’s due to a dead battery or a momentary lapse in judgment, knowing how to safely and effectively jumpstart a car is essential. However, even the most experienced drivers can make mistakes during this process, which can lead to costly damages or even personal injuries. In order to ensure a successful jumpstart without any mishaps, it is important to be aware of the dos and don’ts and to avoid common mistakes. By following proper procedures and understanding what to avoid, drivers can confidently jumpstart their vehicles without any unnecessary complications.

Jumpstarting a car is a skill that every driver should have in their repertoire. Whether you accidentally left your lights on and drained the battery or your vehicle is facing a more serious issue, knowing how to jumpstart a car can save you time and money. However, like any task, there are certain dos and don’ts that should be followed to avoid common mistakes.


1. Use the correct equipment: When jumpstarting a car, you’ll need a set of jumper cables and a vehicle with a fully charged battery. Ensure that the cables are in good condition, with no exposed wires or frayed ends, and that both batteries are of the same voltage (usually 12 volts). If you’re unsure about the voltage, consult your vehicle’s manual.

2. Park the vehicles correctly: Position both vehicles in a way that allows the jumper cables to reach both batteries comfortably. Ensure that both cars are in park (for automatic transmissions) or neutral (for manual transmissions), with their engines off, parking brakes engaged, and ignition keys removed.

3. Connect the cables properly: Begin by connecting one end of the red cable to the positive (+) terminal of the dead battery. Then, attach the other end of the red cable to the positive terminal of the charged battery. Next, connect one end of the black cable to the negative (-) terminal of the charged battery. Finally, connect the other end of the black cable to an unpainted metal surface on the vehicle with the dead battery, such as a bolt or bracket.

4. Start the vehicles and let the dead battery charge: Start the vehicle with the charged battery and let it run for a few minutes. This will allow the dead battery to charge. After some time, try starting the vehicle with the dead battery. If it starts, let it run for a while to ensure that the battery is fully charged.


1. Never reverse the cable connections: It is crucial to connect the cables in the correct order. Reversing the connections can cause damage to the vehicles’ electrical systems, including the alternator, fuses, and even the battery itself. Always connect the positive terminals first, followed by the negative terminals.

2. Avoid touching the metal clamps together: While connecting the cables, ensure that the metal clamps at the end of each cable do not touch each other. Accidental contact can lead to sparks, which can cause injury or damage to the vehicles’ electrical systems.

3. Don’t rely solely on jumpstarting: Jumpstarting a car is a temporary solution to a dead battery. Once the vehicle starts, it’s important to drive it for at least 20 minutes to allow the alternator to recharge the battery fully. If the battery repeatedly dies, it may be time to replace it or have the vehicle’s electrical system checked by a professional.

4. Avoid jumpstarting in extreme weather conditions: Extreme temperatures, especially in freezing weather, can make jumpstarting a car more challenging. Cold weather reduces the effectiveness of batteries, making it harder to start the vehicle. If possible, park the vehicle with the dead battery in a heated area or use a portable battery charger instead.

Jumpstarting a car is a handy skill, but it’s essential to follow the dos and don’ts to avoid common mistakes. By using the correct equipment, parking the vehicles correctly, connecting the cables properly, and avoiding common pitfalls, you can successfully jumpstart a car and get back on the road in no time. Remember, if you’re unsure about any step in the process, it’s always best to consult a professional or seek roadside assistance.
