How to Jump-Start a Car

  1. Gather the Tools: You’ll need another car with a charged battery and a pair of jumper wires.
  2. Position the Cars: Park the two vehicles near one another without coming into touch. Before starting, turn off both cars.
  3. Connect the Jumper Cables:
    • Red Cable: Attach the red jumper cable’s positive end to the dead battery’s positive terminal. The other end should be connected to the functional battery’s positive terminal.
    • Black Cable: Attach one quit of the black (negative) jumper cable to the poor terminal of the running battery. Attach the alternative end to an unpainted metal surface in the engine bay of the car with the lifeless battery. This helps avoid the sparks close to the battery.
  4. Start the Working Car: Let the engine run for a few minutes to charge the dead battery.
  5. Start the Dead Car: After a few minutes, try starting the car with the dead battery. If it starts, let it run for at least 20 minutes to fully charge.
  6. Disconnect the Cables: After the car is running, carefully take off the jumper cables in the opposite order: black from the car that isn’t working, black from the car that is working, red from the car that is working, and finally red from the car that isn’t working.

Situations to Avoid:

  • Wrong Cable Connection: Make sure you always connect the red (positive) wire to the right terminals, and don’t let the black (negative) cable touch any metal parts of the car.
  • Overcharging the Dead Battery: Don’t leave the cars connected for too long after the dead car starts. The battery can be dead if you try to start the car a few times and it doesn’t work.
  • Jump-Starting in Poor Weather: Avoid attempting to jump-start a car in adverse weather conditions, such as rain, snow, or ice, as this can cause electric shock or other issues.

How to jump start a car with jumper cables​

Prepare the Cars: Ensure both vehicles are off, and place them close together. Make sure the jumper cables are in good condition.

Connect the Cables:

  • Attach one red (positive) cable to the positive terminal of the dead battery.
  • Connect the other red cable end to the positive terminal of the working car.
  • Attach the black (negative) cable to the negative terminal of the working battery.
  • The other black cable end should be connected to an unpainted metal part of the dead car, not the battery.

Start the Working Car: Let it run for a few minutes to charge the dead battery.

Start the Dead Car: Wait a little while and then try to start the car with the dead battery. If it starts, let it run for at least 20 minutes to fully charge.

Disconnect the Cables: Take off the cables in the opposite order: black from the working car, red from the working car, and red from the dead car.

Problems You Might Face and How to Fix Them:

  • Car Won’t Start: If you try to start the car multiple times and it still doesn’t work, your battery may be dead. You should replace it.
  • Sparking or Smoke: If you see sparks or smoke when you’re jump-starting, stop right away and check for short circuits or damage. Don’t try to start the car if it shows these indicators.
  • Dead Battery Keeps Dying: If the car starts but then dies again quickly, the battery may not be getting enough charge from the alternator. You should get the alternator looked at.

How long does it take to jump start a car​

It typically takes 5-10 minutes for the working car to charge the dead battery enough to start the car. After that, let the car run for 20-30 minutes to fully charge the battery.

How many amps to jump start a car​

A jump starter or battery with at least 400–600 amps for a small car and 800–1000 amps for a larger vehicle or truck is usually needed to start a car.

How to jump start an automatic car​

To jump-start an automatic car, you do the same things as you would for a manual car, but there are several key things to remember:

  1. Prepare the Vehicles:
    • Ensure both cars are parked close to each other, but not touching.
    • Turn off both vehicles and engage the parking brake for safety.
  2. Position the Cars and Set Up the Cables:
    • Place the car with the dead battery in Park (P) mode.
    • Attach the positive (red) jumper cable to the positive terminal of the dead battery, then to the positive terminal of the working car’s battery.
    • Attach the negative (black) cable to the negative terminal of the operating battery. Then, connect the other end to a metal section of the dead car’s engine bay that isn’t painted (not the battery).
  3. Start the Working Car:
    • Start the car with the charged battery and let it run for 5-10 minutes.
  4. Start the Dead Car:
    • After 5-10 minutes of charging, try starting the dead car. It should start within a few attempts.
    • If the car doesn’t start, wait a little longer and try again. You may need to replace the battery if it doesn’t start after a few attempts.
  5. Remove the Cables:
    • Once the dead car starts, remove the cables in reverse order (black from the metal, black from the working car, red from the working car, and red from the dead car).
  6. Let the Car Run:
    • Keep the engine of the revived car running for at least 20 minutes or drive it around to allow the alternator to charge the battery fully.

Example:

Let’s say you’re trying to jump-start a Toyota Corolla (automatic) with a Honda Civic (working car).

  1. Place the Corolla in Park (P).
  2. Connect the jumper cables, following the proper order.
  3. Start the Honda Civic, let it run, and attempt to start the Corolla after 5-10 minutes.
  4. If the Corolla starts, let it run for at least 20 minutes.

How to jump start a car without another car​

To jump-start a car without another car, you can use a portable jump starter:

  1. Ensure the jump starter is fully charged.
  2. Connect the red (positive) cable from the jump starter to the positive terminal of the dead battery.
  3. Connect the black (negative) cable to the negative terminal of the dead battery.
  4. Turn on the jump starter and wait for a few minutes.
  5. Try starting the car.
  6. If the car starts, remove the cables in reverse order and let the car run for 20 minutes to charge the battery.

How to jump start a car without jumper cables​

You can use a portable jump starter or a bump start (if the vehicle has a manual transmission) to start a car without jumper wires.

  1. Portable Jump Starter:
    • Turn on the portable jump starter and connect it directly to the car’s battery as instructed.
    • Start the car after a few minutes.
  2. Bump Start (Manual Transmission):
    • Push the car while in 2nd gear with the ignition on.
    • Release the clutch quickly while the car is moving to turn the engine over.

Always follow safety precautions during these methods.

How to jump start a hybrid car​

To jump start a hybrid car, follow these steps: First, make sure each car is off and parked close together. Connect the high-quality (red) jumper cable to the fine terminal of the hybrid’s battery, and then to the wonderful terminal of the donor car’s battery. Next, join the bad (black) cable to the negative (-) terminal of the donor vehicle’s battery, and fix the opposite end to an unpainted metallic part of the hybrid’s engine bay. Start the donor car and permit it to run for a couple of minutes. Attempt to start the hybrid vehicle; if a hit, permit it to run for 20 minutes to charge the battery.

How many volts to jump start a car​

To start a car, you typically want a 12-volt power supply. Most car batteries are 12 volts, and jump starters or donor vehicles offer the same voltage. If the voltage is less than 12 volts, the car in all likelihood won’t start, because it won’t provide enough energy to engage the engine. It is important to ensure both the starter or donor car’s battery is fully charged and operating at 12 volts to successfully jump-start a car.
