To help ensure that you don’t end up accidentally damaging yourself, the batteries or both vehicles during the jumping process, it’s important to understand the basic mechanics behind this process as well as what you’ll need to have on hand before you begin.

In this blog post, we’ll explore everything you need to know about jumping a car – including explaining why batteries die in the first place, going over some of the tools you’ll need to have on-hand and breaking down the specific steps required to get your engine roaring again quickly and safely.

Understanding the Jumping Process

The Science Behind Jumping

Jumping a car requires a basic understanding of the science behind it. The primary purpose of jumping is to transfer electrical energy from one car battery to another to start an engine.

It is important to know that a car’s battery produces direct current (DC) electricity while the vehicle’s electrical system operates on alternating current (AC) power. This means that the jump starter connecting the two batteries must be able to convert DC electrical energy into AC power, which can then be used to start the car.

In addition, for successful jumping, both cars should be parked close together, ideally with hoods facing each other and engines turned off. It is crucial to remember not to touch any metal surface during the process to avoid shock or injury.

Types of Jumps and their Applications

There are primarily two types of jumps: parallel and series. Parallel jumping involves connecting the positive terminal of the dead battery to the positive terminal of the charged battery and negative to negative using jumper cables. Once all connections are secure, the driver can try starting the car with the dead battery, and if successful, wait for a few minutes before disconnecting anything.

On the other hand, series jumping eliminates the need for jumper cables by allowing drivers to create a temporary circuit between the two batteries, resulting in a more efficient use of the available voltage. One end of a wire needs to connect to the positive terminal of the functioning battery while the other end connects to its negative pole.

“With modern electronics, you don’t want to risk any additional surges or power issues by potentially hammering those systems with too much power,” says Matt Edmonds, vice president of Tire Rack, adding that a 12-gauge cable is an optimal choice for proper voltage transfer during jumper starts.

While both types of jumps work, parallel jumping is often the default method as it only requires a set of cables and another vehicle. However, series jumping comes in handy when there’s no availability of long cables or vehicles nearby for a jump start.

How long it takes to jump-start your car can vary depending on several factors, such as the age of the battery and its capacity level. Typically, experts recommend running the engine of a functioning vehicle for at least five minutes before attempting to start the dead vehicle’s engine. If successful, wait for another 15-20 minutes before turning off the engine of the newly revived car.

Understanding the science behind jumping and knowing the various methods can help you be better prepared for unexpected situations. Always keep a pair of jumper cables in your trunk, maintain the health of your car battery through regular checkups by professionals, and follow safety instructions to avoid any accidents while doing a jump start.

Factors that Affect Jumping Time

Jumper cables can be a lifesaver when your car battery dies unexpectedly. However, how long it takes to jump-start a car depends on several factors. In this article, we will explore the most common factors that affect jumping time.

Battery Health and Age

The condition of the battery is the primary factor that affects jumping time. If the battery has lost its charge due to neglect or age, it may take longer for the vehicle to start. It is always recommended to replace batteries every five years or earlier if they start to show signs of weakness. Some common signs of a weak battery include slow cranking sound, clicking noise, or engine not starting altogether.

If the battery is in good health, then it should only take a few minutes to jump-start to another vehicle using jumper cables. According to Popular Mechanics, you should give your car around five to ten minutes of running time after jumpstarting it to recharge your battery partially.

Temperature and Weather Conditions

The temperature plays a significant role in how long it takes to jump start a car. Extreme temperatures either too hot or too cold can slow down the chemical reaction within the battery cells, leading to additional time required for jump-start process. The colder the weather outside, the more sluggish your vehicle’s starter motor may become making it harder to crank over the engine. On the other hand, if the weather is hot and humid, the starter motor draws more current from the battery to get the engine started, which also impacts the length of time needed to complete the jump-start process.

In severely low-temperature conditions like sub-zero Celsius or Fahrenheit, the electrolyte solution contained in the battery cells tends to freeze. As a result, the driver might have to wait before carrying out the jump-start process until the battery at least partially warms up to avoid cracks on the fragile components such as cells and plates.

Alternator Output and Charging

The alternator is responsible for charging your battery when you’re driving. If the alternator isn’t working properly, it may take more time to jumpstart an engine because the depleted battery lacks proper power output from the alternator to maintain a good charge. A faulty alternator can lead to flat or dead batteries, which ultimately needs replacement.

Before jumpstarting, check if your car is turning over fast or bogging down. The speed of turnover will give a clear indication whether the issue is with the dead battery or the weak output capacity of your alternator. Proper maintenance of the alternator after every six months not only saves money in the long run but also prevents unnecessary frustrating breakdowns in the middle of nowhere.

Vehicle Make and Model

The make and model play a significant role in how long it takes to jump start a car. For instance, standard hybrid/electric cars have specific instructions that need to be followed before attempting any jump starting process; failure to do this can result in irreparable damages to the vehicle’s electronic systems.

Vehicles with high-performance engines tend to demand more electric juice and incorporate heavier electrical gadgets like sound systems, air conditioners, GPS and multimedia screens. Thus, sport-oriented vehicles typically require longer jumping times due to increased electrical load.

Several factors can impact the jumping time required to get your parked vehicle up and running again when dealing with a dead battery. It is critical to regularly maintain both the battery and alternator to ensure a faster turnaround time during tricky starts, especially in extreme weather conditions.

Essential Tools for Jump Starting a Car

If your car battery dies, you may need to jump start it. This is a simple process that requires minimal tools. In this article, we will focus on the essential tools needed to jump start a car.

Jumper Cables

Jumper cables are the most important tool when jumping a car. These cables have clamps at each end and connect the dead battery with a charged one.

You must ensure that the jumper cables are long enough to reach between both batteries. Generally, four-gauge jumper cables are ideal because they offer sufficient power for most cars.

To avoid accidents while using jumper cables, follow these steps:

  • Turn off both engines before connecting the cables.
  • Connect the red clamp to the positive (+) terminal of the dead battery.
  • Next, connect the other red clamp to the positive (+) terminal of the donor car’s battery.
  • Afterward, attach the black clamp to the negative (-) terminal of the donor battery. It should not be connected to the dead one.
  • Finally, connect the remaining black clamp to an unpainted metal surface in the engine bay of the dead car. Avoid attaching it to the dead battery or the moving parts of the engine.
  • Start the donor car’s engine and let it run for about 5 minutes.
  • Try to start the car with the dead battery. If it starts, immediately disconnect the jumper cables in reverse order.

Jumper cables are easy to use, and with a little practice, you will be able to jump-start your car successfully.

Donor Vehicle

A donor vehicle is the other car that provides power through its battery when jumping a car. Any vehicle can be used as a donor car, but it should have a similar or stronger battery than the dead one. Make sure that both cars are parked close enough so the jumper cables reach without stretching.

“You can’t start a car with a bad alternator by jumping it because the alternator charges the battery while driving” –

If the donor car has a manual transmission, follow these steps:

  • Park your cars facing each other and parallel with enough room between them for the cables to reach both batteries.
  • Turn off both engines, engage the parking brakes, and put both cars in neutral gear.
  • Connect the cables according to the instructions outlined above.
  • Start the donor vehicle’s engine and let it run for about 5 minutes.
  • Next, try starting the car with the dead battery. If it starts, remove the jumper cables in reverse order.

If the donor car is an automatic transmission, avoid touching accelerator pedals during the process. Instead, let it idle for several minutes before removing the cables.

Always ensure that you have jumper cables and a suitable donor vehicle whenever you are driving a car with a weak battery. Take care not to touch the clamps together or connect them improperly to prevent sparks and electrical damage. When done correctly, jump starting a car takes around 10 to 15 minutes, depending on how long you need to keep the donor engine running.

Step-by-Step Guide on How to Jump Start a Car


Before attempting to jump start a car, there are several things you need to consider:

  • Make sure both vehicles’ engines are turned off.
  • Inspect the battery for any signs of damage or leakage. If the battery is damaged, do not attempt to jump start it.
  • If possible, park the donor vehicle close enough to the dead vehicle so that the jumper cables can reach both batteries easily.
  • Wear protective gloves and eye-wear to prevent acid burns or other bodily injury.

Connecting the Jumper Cables

Now that you are prepared, follow these steps to connect the jumper cables:

  1. Identify positive and negative terminals: Locate the positive and negative terminals on both batteries before connecting the jumper cables. The positive terminal is often labelled with a (+) sign.
  2. Connect one end of the red cable: Take one end of the red (positive) cable and attach it to the positive terminal of the dead battery.
  3. Connect the other end of the red cable: Attach the other end of the red cable to the positive terminal of the donor battery.
  4. Attach the black cable: Take one end of the black (negative) cable and connect it to the negative terminal of the donor battery.
  5. Grounding the connection: To complete the circuit, ground the connection by attaching the other end of the black cable to an unpainted metal surface on the dead vehicle away from the battery. This is to prevent any sparks that may arise during the jump start process.

Starting the Donor Vehicle

The next step is to start the donor car:

  1. Start the engine: Turn on the engine of the donor car and let it run for a few minutes. This will allow the battery to charge up properly before trying to start the other car.
  2. Keep revving the engine: Rev the engine of the donor vehicle slightly (around 2000-3000 RPM) and maintain this level throughout the jump start process. This will provide sufficient energy to transfer the current to the dead car’s battery.

Starting the Dead Vehicle

The last step is to start the ‘dead’ vehicle:

  1. Try to start the engine: Try starting the engine of the previously “dead” car. It should turn over easily after being charged by the donor vehicle. If it does not, do not attempt to restart with the jumper cables connected; let the car sit for a while longer or try checking your battery connections again.
  2. Remove cables in reverse order: Once the car has started successfully, remove the cables in reverse order as you attached them: first the black cable from the ground connection on the previously dead car, then the black cable from the negative terminal of the party providing the jumpstart, followed by the red cable from that same positive terminal and finally the red cable from the previously dead battery.
  3. Drive the car around: Drive the car around for at least 20 minutes once it’s running. This will allow the battery to charge properly, ensuring that your car starts next time you try.
