Learn How to Jump-Start a Car Safely and Quickly
Few things are more frustrating than turning your car key and hearing nothing but silence. A dead battery can happen to anyone, but the good news is you can often fix it yourself in just a few minutes with the right tools and know-how. Learning how to jump-start a car is an essential skill every driver should have, especially during emergencies.
What You’ll Need
Before you begin, make sure you have the following items:
- A set of jumper cables
- A working vehicle with a charged battery
- Safety gloves (optional but recommended)
Once you have these ready, you’re all set to bring your dead car back to life.
Step-by-Step Guide to Jump-Starting a Car
Step 1: Park both vehicles close together but not touching. Turn off the ignition and open both hoods.
Step 2: Attach one end of the red (positive) cable to the positive terminal of the dead battery. The positive terminal is usually marked with a “+” sign.
Step 3: Connect the other end of the red cable to the positive terminal of the good battery.
Step 4: Attach one end of the black (negative) cable to the negative terminal of the good battery.
Step 5: Finally, connect the other end of the black cable to an unpainted metal surface on the engine block or frame of the car with the dead battery — not the negative terminal itself. This prevents sparks near the battery.
Step 6: Start the engine of the working car and let it run for about 2–3 minutes.
Step 7: Try to start the dead car. If it doesn’t start, wait another few minutes before trying again.
Step 8: Once the dead car starts, carefully remove the cables in the reverse order of connection (black, black, red, red).
After Jump-Starting
Keep the engine running for at least 15–20 minutes to let the alternator recharge the battery. If the car doesn’t hold a charge after that, the battery might need replacing or there could be an issue with the alternator or wiring.
Safety Tips
- Never let the jumper cable clamps touch each other during the process.
- Ensure both cars are in park (or neutral if manual) with the parking brakes engaged.
- Always check for corrosion or leaks around the battery terminals before connecting cables.
