Jumpstarting your car is a quick and easy way to start a car with a low battery. You’ll need another vehicle with a fully charged battery and a set of jumper cables. Attach the cables to each battery in the correct order, and start the car with the dead battery. Allow the car to run for a few minutes before attempting to drive it.

Park on a Hill

If jumpstarting your car isn’t an option, parking your car on a hill can help. Put the car in neutral and allow it to roll downhill. Once you’ve gained enough momentum, put the car in first gear and quickly release the clutch pedal while pressing the accelerator.

Also known as bump starting, push starting your car involves pushing the car to gain momentum before starting the engine.

Starting a car with a low battery doesn’t have to be a difficult task. Jumpstarting, parking on a hill, and push starting are simple and effective ways to start your car if the battery is low. However, it’s crucial to have your battery checked to avoid damage to your car’s electrical system.

Check the Battery

1. Check Battery Voltage

If your car battery is low, the first thing you need to do is check the battery voltage using a multimeter. This tool helps you measure the voltage being produced by your car battery. A fully charged battery should have a voltage of around 12.6 volts. If it’s less than 12 volts, then your battery is low and needs to be recharged.

2. Inspect the Battery

The next thing to do is to visually inspect the battery. Check for any visible damages like cracks or leaks in the battery case. If you find any, you may need to replace your battery. If the battery looks good, check for corroded terminals. Corrosion may affect the battery’s performance, so clean the terminals using a wire brush.

3. Charge the Battery

3. Charge the Battery

If your battery is low, you need to recharge it. You can connect it to another car battery, or use a battery charger. Make sure to read the instructions carefully before using the charger. Set the charger to the appropriate voltage and amperage level, and connect the charger to your battery. Recharge your battery until it reaches a voltage of around 12.6 volts.

4. Replace the Battery

If your battery is beyond repair, you’ll need to replace it. When buying a new battery, make sure to get one that’s compatible with your car. Check the battery’s amp and voltage ratings to ensure that it’ll work with your car. Remove the old battery and install the new one. Make sure to connect the wires properly and secure the battery in place.

5. Prevention

To prevent your car battery from getting low, make sure to turn off all accessories when the car is not running. Also, avoid leaving your car unused for extended periods as this may drain the battery. Regularly inspect your battery and keep it clean and well-maintained.

  • Check battery voltage
  • Inspect the battery for damages
  • Clean corroded terminals
  • Charge the battery
  • Replace the battery if necessary
  • Prevent the battery from getting low

Use Jumper Cables

Step 1: Find a Car with a Good Battery

Step 1: Find a Car with a Good Battery

To jumpstart a car, you will need another car with a good battery. Choose a car with a battery that is similar in size to your own. Park the two cars close to each other, but do not let them touch.

Step 2: Attach the Jumper Cables

Step 2: Attach the Jumper Cables

Attach the jumper cables to the good battery first. Place the red (positive) cable on the positive terminal of the good battery and then attach the other end of the red cable to the positive terminal of the dead battery.

Next, attach the black (negative) cable to the negative terminal of the good battery. Then, attach the other end of the black cable to an unpainted metal surface on the engine block of the dead car.

Step 3: Start the Good Car

Start the car with the good battery and let it run for a few minutes. This will recharge the dead battery enough to start the car.

Step 4: Start the Dead Car

Try to start the dead car. If it does not start, turn off both cars and check the cable connections. If they are loose, tighten them and try again. If the dead car still does not start, the battery may be dead and need to be replaced.

If the dead car starts, leave both cars running for a few more minutes before disconnecting the cables. Remove the jumper cables in the reverse order that you attached them.

Push Start the Car

  1. Put the key in the ignition and turn it to the “on” position.
  2. Push the car to a speed of 5-10mph.
  3. Depress the clutch and put the car into second gear.
  4. Release the handbrake.
