How To Jump Start a Car?- in Six Easy Step


Jump-starting your car involves using the battery of another vehicle to crank up your engine. If your car is making a startup noise when you turn the key in the ignition but do not fully engage, the battery may need an extra boost. This guide will provide step-by-step instructions on how to jump-start a car.

Most of us spend a significant amount of time in our cars, whether it’s commuting or running errands, or simply enjoying the road. But many of us don’t know the basics of vehicle maintenance or repair. With a little do-it-yourself spirit and a few basic tips, you can learn how to do almost anything on a car.

  2. Prep: Pop the hoods, and locate the batteries. Make sure the jumper cables are unwound and untangled.
  3. Attach: Hook the red (+) clamp to the positive terminal of the dead battery. Then, attach the red (+) clamp to the positive terminal of the working battery. Clamp the black (-) to the negative terminal of the working battery. Finally, attach the remaining black (-) to an unpainted metal surface of the dead car.
  4. Start ‘er up: Start the working car. Start the dead car.
  5. Remove: Remove the cables in the reverse order you attached them.
  6. Let ‘er run: Let the revived car engine run for several minutes at least or drive for at least 15 minutes if possible.

If the car won’t start, check your connections and try again.

How Long Does It Take to Jump a Car?

When your car won’t start, and you’re in a rush, it’s good to know how long it takes to jump a car. You need a second car to boost a battery with jumper cables properly. First, you’ll have to pop open the hood, connect the cables correctly, and then start the good car.

As a rule of thumb, it’s good to wait about two minutes with the car running, letting the power flow through. Then, after two minutes, try and start your vehicle to see if it starts working.

If it starts right up, don’t take off immediately; let your car keep running for at least two minutes, giving your battery enough time to juice up.

So, following that guide, the entire process should take about 5-minutes from connecting to charging. If you drive, park, and your battery won’t restart again, you may have a more severe issue.

You may need to either replace your battery or another car part interfering with your car’s battery.

What do you need to jump a car?

Before you can recharge and get going, you need a few basics:

  • Jumper cables
  • Power source either a portable jump battery (a jump box) or another vehicle

Jumper cables are long, thickly insulated cables with toothed clips on one or both ends. These clips are called alligator clips (because they look like alligator heads). The clips are differentiated by color, usually red and black to indicate positive and negative polarity. The red clip is positive. The black clip is negative.

Jump boxes Portable batteries that can be used to start a vehicle without being connected to another vehicle are supplied with special jump cables. These cables connect the jump battery directly to the dead car battery. A jump box is typically used for roadside assistance when assisting blocked vehicles.

What you need to know about car batteries to jump-start a car

Car batteries have two larger nobs, called terminals. There is a positive and a negative connection. Each should be clearly labeled. Connecting wires to the right terminal are important to complete the circuit and provide power to the dead battery.

  • Positive terminal: The positive pole is usually the larger of the two terminals. It is marked with “POS” or “+”. It connects to the positive terminal on the jumper wire, which is usually red.
  • Negative terminal: The negative pole of the battery is usually marked with “NEG” or “-“. This will be appended to the other clip, which is usually black.
How to jump start a car 
Step 1: Park the vehicles next to each other. 
Step 2: Both vehicles should be off. .
Step 3: Attach one red clamp to the positive terminal on the dead battery. 
Step 4: Attach the other red clamp to the positive terminal on the working battery.

Cautions when jump starting a car:

  • Read your owner’s manual, first. Your manufacturer may advise against jump starting a vehicle due to sensitive electronic circuitry.
  • Don’t try to jump a frozen battery.
  • Do NOT jump a battery that is cracked or leaking. This is very dangerous. You will need to purchase a new battery at this point, so call a tow truck or a friend that can help you out.
  • Ensure that the battery isn’t dry. Check individual cells for fluid levels and add water accordingly. Check your owner’s manual for details and warnings.
  • If there is corrosion (white or greenish powdery stuff) on the battery, try to clean it off with a wire brush, aluminum foil or anything but your hand as the chemicals can be damaging to your skin. Be sure you cover your nose and mouth to avoid inhaling the dust as it is a lung irritant.
  • Once you begin the process of hooking the cables up NEVER allow any of the hook-up clamps to touch. Each person should hold an end of the cables and keep the two clips separate (one to each hand is a good idea).

Step-By-Step Guide: How to Jump a Car?

  1. Start by protecting your clothes and your hands with protective clothing or a blanket on the ground and gloves.
  2. Open the hood to your car. Sometimes when you “pop” the hood, you need to also release the latch. This can be found by running your fingers under the slightly open hood until you find a little lever to push on. Use the stick to prop the hood open while you work.
  3. Locate the battery. If you aren’t sure where to find the battery, your owner’s manual should provide instructions or a picture to guide you.
  4. Ensure that the donor car is parked close to yours and that it is turned off before you start.
  5. On the battery there are two post “terminals”. One is positive (+), usually red and one is negative (-), usually black.
  6. The positive terminal post (+ or red) should have a plastic cover that opens easily to expose the metal beneath. Keep in mind that when you begin to attach the cables to each component, you want it to be as solid as possible to ensure a safe and complete connection.
  7. Take a POSITIVE (red) clamp and attach it to the dead car’s positive terminal post (+ or red). The clamps should have metal teeth that help them grip the terminal post.
  8. Take the POSITIVE (red) clamp at the opposite end of the cables and attach it to the positive terminal post (+ or red) of the good, working battery. Their car should still be off!
  9. Next, take the NEGATIVE (black) clamp on that end and attach to the (-) terminal of the good, working battery.
  10. Take the final NEGATIVE (black) clamp and attach it to a non-painted metal surface on the main engine block of the car that is being jump-started (yours). A good metal surface could be a metal nut or bolt and farther away from the battery is better to allow for solid grounding.
  11. At this point, once all of the connections have been secured, start the donor car. After a few minutes, try to start your car. If your car won’t start, then wait several more minutes and try again.
  12. If this doesn’t work, stop. Working in reverse order, unhook each of the clamps and thank the owner of the donor car. It’s time to call for professional help.
  13. When the dead car is started, check the battery light on the instrument panel. If it is on, this may mean that the alternator is not charging the battery and the driver should not run the vehicle very long. If this is the case, call for professional help.
  14. If your car does start, let it run for a few minutes to help charge the battery further.
  15. Unhook the clamps in the reverse order of how you put them on. Be sure to drive your car for about 30 minutes before stopping again so the battery can continue to charge. Otherwise, you might need another jump start.

For the true do-it-yourselfer, look into a Jump Start Box or Jump n’ Carry. These small boxes run about $150, but they can provide you with a solo jump-start regardless of where you are. Be sure to read the details and your owner’s manual to ensure this is an option for your vehicle.

how to jump a car with jumper cables?

To safely jump a start, follow these steps:

  1. Take out your jumper cables: It is a good idea to buy a set of jumper cables and store them in the trunk compartment. If you don’t have jumper cables.
  2. Put both vehicles in Park or Neutral and turn off the ignition in both vehicles. And also apply both parking brakes.
  3. Attach one of the red clips to the positive terminal of your battery. It has “POS” or “+” or it is larger than the negative terminal.
  4. Attach the other red clip to the positive terminal of the other car.
  5. Attach one of the black clips to the negative terminal on the other battery.
  6. Attach the last black clip to an unpainted metal surface on your car that isn’t near the battery. Use one of the metal struts that holds the hood open. The cables should look like this as per shown image.
  7. Start the working vehicle and let the engine run for a few minutes.
  8. Try to start your vehicle. If it doesn’t start, make sure the cables are connected properly and let the Good Samaritan run his engine for five minutes. Then try starting your car again. If it still does not start, your battery may be of no help.
How to Jump a Car

After the car is jump started:

Unclip the clips in the reverse order you connected them:

  • The black clip on the unpainted metal
  • The black clip from the negative terminal
  • Red clip from the donor car
  • Red clip from the dead car’s battery

Allow the car to run without stopping for a minimum of 10-20 minutes.

What if the car doesn’t start after the jump start?

If the dead car doesn’t start after a few minutes of being powered then:

  1. Check the connections and repeat letting the car giving the jump run.
  2. Try starting the car again.
  3. If the car does not start after several attempts, the battery may be too far gone to be jump started.
