Introduction: Why Knowing How to Jumpstart a Car Matters
A dead battery can strike at the worst time—when you’re late for work or stuck in a parking lot. Knowing how to jumpstart a car safely not only gets you back on the road but also protects your vehicle from damage. This guide walks you through the step-by-step process, safety precautions, and mistakes to avoid.
Step 1: Gather the Right Tools
Before you begin, make sure you have:
- Jumper cables (12–20 feet recommended)
- A working vehicle with a charged battery
- Gloves and safety glasses for extra protection
Step 2: Position the Cars Correctly
- Park the working vehicle close to the dead one, but ensure they do not touch.
- Turn off both ignitions and set parking brakes.
- Open the hoods and locate both batteries.
Step 3: Connect the Jumper Cables in the Right Order
The correct sequence is crucial when jumpstarting a car safely:
- Attach the red (positive) clamp to the dead battery’s positive terminal (+).
- Attach the other red clamp to the live battery’s positive terminal (+).
- Attach the black (negative) clamp to the live battery’s negative terminal (–).
- Attach the last black clamp to an unpainted metal surface of the dead car (not the battery).
Step 4: Start the Cars
- First, start the working car and let it run for 2–3 minutes.
- Then, try starting the dead car.
- If it doesn’t start immediately, wait another minute before trying again.
Step 5: Remove the Cables Safely
Once the dead car starts, carefully remove the cables in the reverse order:
- Black clamp from the grounded metal surface
- Black clamp from the live battery
- Red clamp from the live battery
- Red clamp from the dead battery
Let the revived car run for at least 15–20 minutes to recharge the battery.
Extra Safety Tips
- Never let the clamps touch while connected.
- Avoid jumpstarting a car if the battery is leaking or swollen.
- For hybrid and electric vehicles, follow manufacturer guidelines.
