How to Start Car With Low Battery

Last Updated on May 14, 2023 by Ryan

To start a car with a low battery, you will need to jumpstart the vehicle. To do this, you must have another car and jumper cables. Park the active vehicle close to the one with an inactive battery, ensuring that both vehicles are in park or neutral and that their parking brakes are engaged.

Turn off all accessories on both cars then connect one end of each cable to the negative terminal (-) on the dead battery first. After connecting those two ends, attach the other end of each cable to the corresponding positive terminals (+) of both batteries; be sure not to let any metal objects or tools touch multiple terminals at once. Finally, start up your active vehicle and leave it running for around 5 minutes before attempting to start your low-battery car – if successful, drive for at least 15 minutes before turning off your engine again so that power can recharge sufficiently.

  • Check the battery voltage: Before attempting to start the car, check the battery voltage with a voltmeter
  • If it’s below 12 volts then you will need to charge or jump-start it in order to get it running again
  • Charge or Jump-Start: Connect a charger or jumper cable directly to the battery terminals and attach them to another vehicle that is running and has enough power for your vehicle’s starter motor
  • Allow this connection for at least 10 minutes before attempting to start your car so that you can provide enough energy for it to turn on successfully
  • Try Starting Your Car: Once you have charged up your battery, try starting your car by turning the key in the ignition switch with no other accessories turned on (i
  • , lights, radio)
  • After allowing some time for everything electrical system components of your vehicle to turn off completely after being shut down previously, try cranking up your engine again – this should give an extra boost of power from its own alternator which will help keep things going even when there is not much left in terms of juice from its original source (battery)
  • Monitor Voltage Levels: While driving around make sure that you monitor voltage levels as they could drop back down if something else gets drained while operating due to lack of overall stored energy within the cell itself – be prepared to stop and recharge/jump-start right away if the situation calls for repeated attempts at getting started without success each time!

3 Easy Tricks To Start a Dead Car – Without Jumper Cables

8 Steps Jump-Starting a Car with a Low Battery

Jump-starting a vehicle is a straightforward process, but it’s essential to follow the steps correctly to ensure safety and success. Here is a detailed guide:

Step 1: Gather Your Tools

You will need a set of jumper cables and a second car with a fully charged battery. Make sure the jumper cables are in good condition, without fraying or exposed wires.

Step 2: Position the Cars

Both vehicles should be turned off. Position them so that they are facing each other, about 1 to 2 feet apart, but not touching. The batteries need to be close enough that the jumper cables can reach each one.

Step 3: Identify the Battery Terminals

Open the hoods of both cars and locate each car’s battery. Identify the positive (+) and negative (-) terminals. They should be marked with a plus or minus symbol or colored red (positive) and black (negative).

Step 4: Connect the Jumper Cables

Start with the dead battery. Connect one end of the red (positive) jumper cable to the positive terminal of the dead battery. Connect the other end of the red cable to the positive terminal of the good battery. 

Next, connect one end of the black (negative) jumper cable to the negative terminal of the good battery. 

Finally, connect the other end of the black cable to an unpainted metal surface on the car with the dead battery, not to the battery itself. This could be a clean nut or bolt on the engine block.

Step 5: Start the Working Car

With the cables connected, start the engine of the good car. Let it run for a few minutes. This allows the dead battery to draw power from the good battery.

Step 6: Start the Dead Car

After a few minutes, attempt to start the car with the dead battery. If it starts, let both cars idle for a few more minutes to further charge the dead battery.

Step 7: Disconnect the Cables

After the dead car is successfully started, you can begin to disconnect the jumper cables. Start with the black (negative) jumper cable attached to the car that was jump-started, then remove the other end of the black cable from the booster car. After that, remove the red jumper cable from both cars.

Step 8: Keep the Jump-Started Car Running

Drive the jump-started car around for at least 15 to 30 minutes to allow the battery to recharge further. Avoid turning the car off during this time.

Remember, this guide is a general process, and specifics may vary based on your car’s make and model. Consult your vehicle’s manual for precise instructions. If your car doesn’t start after trying this process, it’s advisable to seek help from a professional mechanic.

Troubleshooting: What to Do If Your Car Still Won’t Start

If your car doesn’t start after attempting a jump-start, it could be due to a number of issues, not just a dead battery. Here’s a guide to troubleshooting other potential problems:

Check the Jumper Cables: 

Make sure the jumper cables are properly connected and that the clamps are firmly attached to the battery terminals. If the cables are loose, they may not be able to deliver the necessary power to start your car.

Check the Battery Connections: 

Corrosion on the battery terminals can prevent a good connection. If the terminals are dirty or corroded, clean them with a brush and a mixture of baking soda and water, then try to jump-start the car again.

Inspect the Starter Motor: 

If you hear a clicking noise when you turn the key, the issue might be with your starter motor, not the battery. The starter motor is responsible for turning the engine over during ignition. If it’s faulty, it may need to be replaced.

Check the Fuel Supply: 

Your car might not be starting because it’s out of fuel or the fuel isn’t being delivered to the engine. Check your fuel gauge and make sure the fuel pump and injectors are functioning properly.

Check the Ignition Switch: 

If your car isn’t starting and there’s no sound at all, the problem could be with the ignition switch. You might need a professional mechanic to diagnose and replace it if necessary.

Examine the Timing Belt: 

A broken timing belt can prevent your engine from starting. If the timing belt is broken, you’ll likely need to have it replaced by a professional mechanic.

Check for Engine Problems: 

If your engine is making unusual noises or if you notice smoke, the problem could be serious. In this case, it’s best to have your car towed to a professional mechanic for a thorough inspection.

If you’re unable to identify or fix the problem, it’s best to call a professional for help. Continuing to try to start the car could potentially cause more damage. Be sure to explain any noises, smells, or other issues you’ve noticed, as these can help the mechanic identify the problem.

Safety Precautions When Handling Car Batteries

Regular inspection is key. Look for signs of corrosion or leaks. If you notice white, powdery substances around the terminals, that’s a sign of corrosion. Cleaning the terminals can often extend the battery life.

2. Keep the Battery Clean: 

Dirt and grime can cause the battery to drain quicker. Use a mixture of baking soda and water to clean the top of the battery and the terminals.

3. Ensure Secure Connections: 

Loose battery cables can cause a weak or no-start condition. Make sure the battery connections are tight and secure to prevent this.

4. Charge the Battery Fully: 

If you mainly use your vehicle for short trips, the battery might not get fully charged, which can shorten its lifespan. An occasional longer trip or a short period on a battery charger can keep the battery fully charged.

5. Avoid Draining the Battery: 

Using the radio, lights, or air conditioning when the car isn’t running can drain the battery. If you’re not driving, it’s best to turn off these accessories.

6. Test the Battery Regularly: 

Have your battery tested by a professional mechanic at least once a year, especially if it’s more than two years old. They can check its output voltage level and other related components, such as the alternator and the starter, to ensure they’re working correctly.

7. Protect the Battery from Extreme Temperatures: 

Both high and low temperatures can shorten a battery’s lifespan. If possible, park your car in a garage in the winter and find shaded areas in the summer.

8. Replace Old Batteries: 

If your battery is more than three years old, consider having it replaced. Car batteries can fail without warning, so it’s better to replace them before they’re dead.

Preventive maintenance can help extend the life of your car battery, but remember that all batteries will eventually need to be replaced as part of regular vehicle maintenance.

How to Start Car With Low Battery


How Do You Manually Start a Car With a Dead Battery?

If you find yourself with a dead battery and no jumper cables, it is possible to manually start the car. This process is known as ‘jump-starting’ and involves connecting an external power source (usually another car or a portable jump starter) directly to the battery terminals of your vehicle. First, locate the positive (red) and negative (black) terminals on your car’s battery.

If available, attach the positive cable from the donor vehicle first and then connect it to your own car’s positive terminal. Then do the same for negative terminal connections. Make sure all connections are secure before attempting to start either engine – if done correctly, this should provide enough energy for your own engine to turn over after several attempts at starting it.

How Can I Start My Car With Low Battery Without Pushing It?

If you have a car with a low battery, there are several ways to start it without pushing it. First, if you have access to jumper cables and another vehicle, then you can use that vehicle’s battery power to jump-start your own. Make sure that the other vehicle has a healthy battery before attempting this method.

If not, the second option is to try using a portable jump starter or booster pack; these devices store some electrical charge so they can be used instead of relying on another car’s battery power. Lastly, if all else fails, you may need to call in professional assistance who will be able to help get your engine started again safely and effectively.

Will Car Not Start If the Battery is Low?

Yes, a car will not start if the battery is low. This can happen when the battery has been drained of its charge due to being left on without running or if it’s simply worn out and needs to be replaced. The most common sign that a car won’t start because of a weak battery is when there are no lights on the dashboard and/or no sound from the starter motor.

When this happens, you should check your alternator belt, terminal connections, and charging system before replacing the battery as these could be causing the issue instead.


Starting a car with a low battery can be intimidating, but it is possible. With the right tools and techniques, you can jumpstart your car’s battery in no time. Remember to turn off all electronics before attempting to start the vehicle and make sure both cars are not running while connecting jumper cables.
