How to Jump-Start a Car & When to Call for Help
A dead battery can leave you stranded at the worst possible time. Knowing how to jump-start a car can get you back on the road quickly, but sometimes, it’s best to call for professional help.
In this guide, we’ll walk you through the step-by-step process of safely jump-starting your car and how to know when it’s time to call roadside assistance.
What You Need to Jump-Start a Car
Before starting, make sure you have:
✅ Jumper cables (at least 10-12 feet long)
✅ A working vehicle (with a fully charged battery
)✅ Gloves & safety glasses (optional but recommended)
⚠️ Safety First: If you notice leaking battery acid, a swollen battery, or a burning smell, do not attempt a jump-start. Call a professional instead.
Step-by-Step Guide to Jump-Starting a Car
Step 1: Position the Vehicles
Park the working car close to the dead car but don’t let them touch.
Turn both cars off and engage the parking brakes.
Step 2: Connect the Jumper Cables
Attach the Red Clamp – Connect one red clamp to the positive (+) terminal on the dead battery.
Attach the Other Red Clamp – Connect the other red clamp to the positive (+) terminal on the working battery.
Attach the Black Clamp – Connect one black clamp to the negative (-) terminal on the working battery.
Ground the Last Black Clamp – Attach the last black clamp to an unpainted metal surface on the dead car (like a bolt or engine block) to prevent sparks.
⚠️ Do NOT attach the black clamp to the dead battery’s negative terminal. This could cause sparks and potential battery damage.
Step 3: Start the Working Car
Let the working car run for 2-5 minutes to charge the dead battery.
Step 4: Try to Start the Dead Car
Turn the key in the ignition. If it starts, let it run for at least 15 minutes to recharge the battery.
If it doesn’t start, wait another few minutes and try again.
Step 5: Remove the Jumper Cables (In Reverse Order)
Remove the black clamp from the metal surface on the dead car.
Remove the black clamp from the working battery.
Remove the red clamp from the working battery.
Remove the red clamp from the previously dead battery.
⚠️ Avoid letting the clamps touch each other while removing them.
When to Call for Help
If your car still won’t start after a jump, you may have a bigger problem. Here’s when to call a roadside assistance service:
🚨 Battery is completely dead – If your battery is over 3-5 years old, it may need replacement.
🚨 Clicking sound but no start – Could indicate a bad starter or alternator issue.
🚨 Dim lights or electrical issues – Your alternator may not be charging the battery properly.
🚨 No jumper cables or second vehicle available – If you’re alone and can’t get a jump, call a roadside professional.
🚨 Battery terminals are corroded or damaged – Cleaning them may help, but extreme corrosion can prevent a proper charge.
🚨 You're in an unsafe location – If you’re stuck on a busy highway or unfamiliar area, it’s safer to call for assistance.
