How to Jumpstart a Car: A Simple Step-by-Step Guide for Drivers

There’s nothing worse than getting into your car, turning the key, and hearing nothing but a clicking sound. A dead car battery can happen at the most inconvenient time, especially during the cold winter months.

Whether you're heading to work, running holiday errands, or preparing for a Christmas road trip, knowing how to jumpstart a car can save you time and stress.

Why Won't My Car Start?

A weak or dead battery is one common reason a vehicle won't start. You may notice:

• A clicking sound when turning the key

• Dashboard lights that look dim

• The engine cranking slowly

• No response when pressing the start button

Cold temperatures can make it harder for a battery to deliver power, so winter is an especially important time to pay attention to battery condition.

What Do You Need to Jumpstart a Car?

Before getting started, you'll generally need:

• A working vehicle with a compatible 12V battery, or

• A portable car jump starter designed for your vehicle

• The vehicle owner's manual

• Protective equipment recommended by the manufacturer

Always check your owner's manual and jump starter instructions before connecting anything. Some vehicles have specific jump-starting procedures or designated connection points.

How to Jumpstart a Car With Jumper Cables

If you're using jumper cables and another vehicle:

1. Park the vehicles close enough for the cables to reach, without allowing the vehicles to touch.

2. Turn off both vehicles and all electrical accessories.

3. Identify the correct positive and negative battery terminals or designated jump points.

4. Connect the red clamp to the positive (+) terminal of the dead battery.

5. Connect the other red clamp to the positive (+) terminal of the working battery.

6. Connect the black clamp to the negative (-) terminal of the working battery.

7. Connect the final black clamp to an approved grounding point on the disabled vehicle, following the vehicle manual.

8. Start the working vehicle if the manufacturer's instructions allow it, then attempt to start the disabled vehicle according to the instructions.

Remove the clamps in the reverse order, keeping them from touching each other or moving parts.

Important: Never attempt a jump-start if the battery is cracked, leaking, swollen, frozen, or visibly damaged. Stop if you are unsure about the correct connection points.

Can You Jumpstart a Car Without Another Vehicle?

Yes. A portable car jump starter can provide another option when no second vehicle is available.

These compact devices are designed to deliver starting power to a compatible vehicle battery. Depending on the model, some also include a built-in air compressor, tire pressure display, LED light, or USB charging ports.

That makes a portable jump starter a useful item to keep in your trunk, especially during winter and holiday travel.

Be Prepared Before Your Next Drive

A dead battery doesn't have to turn a normal day into a major inconvenience. Keep your vehicle's battery in good condition, learn the correct jump-starting procedure, and consider carrying a portable jump starter that matches your vehicle's requirements.
