Knowing how to jump a car is essential for every driver. Whether you’re stranded in a parking lot or helping a friend, here are 4 proven methods to revive a dead battery, complete with step-by-step instructions, safety tips, and the tools needed.

Method 1: Traditional Jumper Cables

Tools Needed:
✅ Jumper cables (10-12 gauge)
✅ A working vehicle with a charged battery
✅ Safety gloves & goggles

Step-by-Step Guide

1. Park Safely

• Position cars nose-to-nose or side-by-side (no touching).
• Turn off both engines and engage parking brakes.

2. Connect the Cables

• Follow this exact order to avoid sparks or damage:

⚠️ Never connect the black clip to the dead battery’s (–) terminal.

3. Start the Working Car

Let it idle for 3-5 minutes to charge the dead battery.

4. Start the Dead Car

Turn the ignition. If it fails, wait 2 minutes and retry.

5. Disconnect Cables

Reverse the order: Remove black clips first, then red.

Method 2: Portable Jump Starter (No Second Car Needed)

Tools Needed:
✅ Portable lithium-ion jump starter (e.g., NOCO Boost)
✅ Built-in clamps or cables

Step-by-Step Guide

1. Charge the Jump Starter
   • Ensure it’s fully charged (most have LED indicators).
2. Connect to the Dead Battery
   • Attach the red clamp to the (+) terminal.
   • Attach the black clamp to an unpainted metal surface (e.g., engine block).
3. Power On the Device
   • Turn on the jumpstarter (some models auto-detect voltage).
4. Start the Car
   • Turn the ignition immediately.
5. Disconnect
   • Remove the clamps in reverse order (black first, then red).

Method 3: Push-Start (Manual Transmission Only)

Tools Needed:
✅ 2-3 strong helpers (or a downhill slope)

Step-by-Step Guide

1. Turn the Ignition to “On”
   • Do NOT start the engine yet.
2. Press the Clutch
   • Depress the clutch pedal fully.
3. Get the Car Rolling
   • Have helpers push the car (or roll downhill) until it reaches 5-10 mph.
4. Release the Clutch
   • Quickly release the clutch while in 2nd gear.
   • The engine should turn over and start.
5. Press the Clutch Again
   • Once started, press the clutch to avoid stalling.

Method 4: Battery Charger (Slow but Safe)

Tools Needed:
✅ Battery charger (trickle or smart charger)
✅ Extension cord (if needed)

Step-by-Step Guide

1. Connect the Charger
   • Attach the red clamp to the (+) terminal.
   • Attach black clamp to the (–) terminal.
2. Plug In and Set Mode
   • Choose a slow charge (12V) for safety.
3. Wait for a Full Charge
   • Most chargers take 4-24 hours (check the manual).
4. Start the Car
   • Once charged, disconnect the charger and start the engine.
