How Long Should A Car Run After Getting A Jump

Key Takeaways
● Jumpstarting a car is an effective way to get it up and running again.
● The time the vehicle runs after a jumpstart depends on several factors, including the car battery’s condition and how much charge is left in it.
● If your car needs to be jumpstarted more often, it’s a good idea to have the car battery tested and replaced if necessary.

Are you a car owner who’s ever been in a situation where your car won’t start? If so, you’ve probably had to ask someone for a jump. But once you get that jump, what do you do next? How long should your car run after getting a jump?

The answer depends on several factors, including the condition of your battery and how much charge is left in it. Generally, you should run your car for at least 30 minutes after getting a jump start so the car battery can recharge.

In this article, we’ll discuss the factors behind how long a car should run after getting a jump, as well as tips on how to keep it running longer and safer.

What Happens When You Jump A Car?

What Happens When You Jump A Car

When you jump a car, it involves connecting the battery of ANOTHER vehicle to your own that has a dead battery. This provides enough power to get your engine running again.

However, this only works if the other car’s battery is CHARGED; otherwise, it won’t be able to provide enough power to start your vehicle.

Once connected, the starting CURRENT from the other car’s battery will pass through the cables and get your engine going. This allows it to generate its power, which is then used to recharge your battery.

Pro Tip: Ensure you connect the cables correctly and in the right order – positive to positive, negative to negative – to avoid any electrical problems [1].

Factors Affecting How Long A Car Will Run After Jumpstarting

Factors Affecting How Long A Car Will Run After Jumpstarting

The time a car will run after jumpstarting depends on various factors. Here are some of the most important ones:

Battery Condition

One of the key factors affecting how long a car will run after jumpstarting is its battery condition.

A weak or damaged battery WON’T be able to hold a charge for very long, so it’s essential to have your battery checked regularly and replace it if necessary.

Electrical System Issues

ANY issues with the electrical system, such as a faulty alternator or a bad starter motor, can cause the car to shut down after a few minutes of running [2].

Check your car’s electrical system regularly and replace worn or damaged parts.

Battery Size

Larger car batteries can store MORE power than smaller ones, so they can run for extended periods after being jumpstarted.

Charging Time

The amount of time it takes to recharge the battery depends on the size and condition of the battery as well as the AMPERAGE of the charging source [3]. A weak or damaged battery will take longer to charge, while a healthy one can be recharged in minutes.

Engine Load

The load put on the engine can also affect how long it will run after being jumpstarted. If your car is carrying an extra heavy load, such as when TOWING a trailer, it may not be able to run for very long before needing another jump start.

As a general rule of thumb, you should run your car for at least 30 minutes after getting a jump start so the battery can recharge. This will give it enough time to build up a good charge level.

If you can drive the car during this period, it’s even better as this will help the battery recharge faster. However, if the battery cannot hold a charge for this long, it’s likely that it needs to be REPLACED.

Pro Tip: Once the car has been running for a while, disconnect the cables from the other vehicle and start your engine again.

What To Do if the Vehicle Shuts Off Quickly After Jumpstart

What To Do if the Vehicle Shuts Off Quickly After Jumpstart

If your vehicle shuts off quickly after the jumpstart, it’s best to seek PROFESSIONAL help. The cause could be something simple, such as a weak battery, faulty alternator, or more complex.

A qualified MECHANIC can diagnose and repair the issue, so you don’t have to worry about your car shutting down again.

In some cases, the issue could be severe enough to be replaced. In any case, seeking professional help is always the BEST option when dealing with trouble from your car batteries charge.

Tips for Keeping the Car Running Longer And Safer

Tips for Keeping the Car Running Longer And Safer

Here are some tips to keep in mind to ensure your vehicle runs for longer and more safely after a jumpstart.

  • Check the battery terminals and cables to ensure they are securely connected and not corroded or loose.
  • Avoid driving too far with a weak or discharged battery, as this can cause it to overheat or even explode.
  • Avoid high-powered accessories such as heated seats, air conditioners, and car stereos when the battery is low, as this will put extra strain on it.
  • Keep your battery charged regularly using a trickle charger or similar device.

Safety Considerations When Jumpstarting Your Car

Safety Considerations When Jumpstarting Your Car

Here are a few safety considerations to bear in mind when jumpstarting your car:

  • Be sure to follow the manufacturer’s instructions carefully.
  • Wear protective gear like gloves and eye protection when jumpstarting a car.
  • Make sure both cars are off while hooking up the jumper cables, and never touch the metal clamps together or allow them to come into contact with any other metallic objects.
  • Keep your hands and feet away from moving parts such as fans, belts, and pulleys.
  • Do not attempt to jumpstart a car if you do not have the correct cables or any previous experience.
  • Check that the battery terminals are insulated before attempting to connect them.

Frequently Asked Questions

Frequently Asked Questions

Can I Use A Battery Charger Instead Of A Jumpstart?

Yes, it is possible to use a charger instead of a jumpstart. However, read the instructions carefully before doing so and find one suitable for your vehicle’s battery type.

What Kind Of Cables Should I Use To Jumpstart A Car?

Using the correct type of cables for jumpstarting a car is essential. Make sure the cables you are using are rated for the amperage and voltage of your vehicle’s battery. 

It is recommended to use heavy-duty jumper cables with thick clamps to make sure the right amount of current is transferred between the two batteries. Make sure the cable length is enough for both cars to be parked far apart from each other.

Is It Safe To Jumpstart A Vehicle Multiple Times?

It is not recommended to jumpstart a vehicle multiple times. Doing so can damage the alternator and cause other components to overheat, resulting in severe engine damage.

If you need to jumpstart your car more than once, it is best to take it to a professional mechanic or auto shop for proper diagnosis and repair.

Does Revving the Engine Charge the Battery Faster?

No, revving the engine will not charge the car’s battery faster. In fact, it can damage or overheat the alternator and other components in the vehicle.



Jumpstarting a car can be a quick and easy way to get it running again, but some safety considerations need to be considered.

Make sure you have the correct type of cables, follow the manufacturer’s instructions, wear protective gear, and take extra care when jumpstarting your car.

Following these tips ensures that your car will run safely and reliably for a more extended period after getting a jump start. ​
