Understanding Jumper Cables
Jumper cables, as you might guess, are highly essential tools, especially during an emergency. Having a clear understanding of what they are and how they work can save you in a situation where your car battery goes flat.
What are Jumper Cables?
Jumper cables, also known as jump leads or boost cables, are a pair of electrical cables with alligator clamps at either end. They are used to transmit power from a live vehicle battery to another one that’s dead or underpowered, hence the term ‘jump starting’ a car. This process lends a quick boost to the dead battery allowing your car to start.
Different Types of Jumper Cables
There are several types of jumper cables out there in the market, differing in size, length, and construction material. Some popular ones include light-duty cables, suitable for small cars and motorcycles; medium-duty cables, well-suited for mid-to-large size cars; and heavy-duty cables, suitable for light trucks, SUVs, or larger vehicles. When choosing jumper cables, a good rule of thumb is to pick ones with thick wires and strong clamps that can transmit power effectively.
Importance of Jumper Cables
Jumper cables are extremely important for every vehicle owner. You never know when your car’s battery might give out, and having a set of jumper cables in your trunk can be a lifesaver. They are an inexpensive solution to a potentially costly problem. Plus, not only can they help you in a pinch, but you could also use them to help someone else out.
Basic Precautions to Take Before Jump Starting a Car
Just like any electrical process, jump starting your car involves certain risks. So, before you pull out those jumper cables, you need to take some basic precautions.
Ensure Both Cars are in Park or Neutral
The first thing you need to ensure is that both cars—your car with the dead battery and the car with the good battery—are in park or neutral. This prevents the cars from accidentally moving during the jump start process, keeping you safe.
Make Sure Both Cars are Turned Off
Next, make sure both vehicles are turned off. Jump starting a car with either of the vehicles in a running state could lead to electrical complications or even accidents.
Wear Protective Clothing
Do wear protective clothing, preferably a pair of safety gloves and goggles, to protect you from any potential sparks or acid splashes when working on the battery.
Examine the Battery for Damages
Give a thorough look at the battery before you start the jump start process. If you observe any leaks, cracks, or other damages to the battery, refrain from jump starting. Seek professional assistance instead.

Identifying Battery Terminals
Before connecting the jumper cables, it’s essential to correctly identify the battery terminals.
Recognize Positive and Negative Terminals
Batteries usually have two terminals: one positive (+) and one negative (-). They are typically marked with the “+” and “-” signs. Sometimes, instead of signs, they can be color-coded—red for positive and black for negative.
Cleanliness and Visibility of the Terminals
Ensure that the terminals are clean and visible. Dirt, dust, or corrosion may hinder the jump start process. If the terminals are dirty, clean them with a wire brush before proceeding.
Understanding the Colors Red and Black on Terminals
In the world of electronics, colors are more than cosmetic—they signify certain standards. In the case of battery terminals, red indicates the positive terminal and black indicates the negative one. It’s integral to remember these color codes to correctly connect the jumper cables and effectively jump start your car.
Arranging the Cars for Jump Starting
In order to jump start a car effectively, it’s crucial to arrange the vehicles correctly.
Positioning Cars Nose to Nose
When preparing to jump start a car, align the cars nose-to-nose, or side-by-side, ensuring the batteries are as close as possible. Note that they should be close enough for the jumper cables to reach, but not touching.
Avoiding Direct Contact of Cars
It’s essential to avoid direct contact of the cars as it could lead to a short circuit. Moreover, remember to keep all parts of your body away from the moving parts of both cars.
Making Sure Cables Can Reach Both Batteries
Check that your jumper cables can span the distance between the batteries of both cars. Jumper cables come in various lengths, so ensure you’re using one that suits the distance between your cars.

Connecting the Jumper Cables
As you prepare to breathe life back into your vehicle, ensure you’re connecting the jumper cables correctly.
Order of Connecting the Jumper Cables
This is the crucial stage—connecting the jumper cables. The process is straightforward but must be executed in the correct order. Start by attaching one of the red clamps to the positive terminal (+) on the dead battery, then attach the other red clamp to the positive terminal on the good battery.
Connecting Red clamp to Positive Terminal
After the positive terminals have been connected, move on to the negatives. Attach the black clamp to the negative terminal (-) on the good battery.
Connecting Black clamp to Negative Terminal
Finally, attach the remaining black clamp to an unpainted metal surface on the car with the dead battery (not to its negative terminal). A clean nut or bolt on the engine block is a good option.
Starting the Car with Dead Battery
After correctly connecting the jumper cables, it’s time to attempt starting the car with the dead battery.
Letting the Working Car’s Engine Run
Start by turning on the car with the good battery and let it run for a few minutes. This allows its battery to supply a charge to the dead battery.
Attempt to Start the Car with the Dead Battery
After a few minutes, try starting the car with the dead battery. If the vehicle doesn’t start immediately, wait a few more minutes, ensuring the jumper cables are securely connected, and try again.

What to Do if Car Doesn’t Start
In case the car with the dead battery doesn’t start, follow these steps.
Check the Cable Connections
Initially, double-check your cable connections. Make sure they are attached securely and correctly to the terminals.
Let the Working Car’s Engine Run Longer
If the connections seem fine, turn on the working car’s engine and let it run a little longer to charge the dead battery.
Seek Professional Assistance
If your car still doesn’t start, you might need professional help. It’s possible that the issue isn’t the battery but something else, such as the alternator or the starter.
Disconnecting the Jumper Cables After Jump Starting
Once you’ve successfully jump started your car, you need to safely disconnect the jumper cables.
Proper Order of Disconnecting the Jumper Cables
Just like connecting jumper cables, disconnecting them should also follow a specific order. Start by removing the black clamp from the car that was jump started (the one attached to the unpainted metal surface), then the black clamp from the working car. Follow this by removing the red clamp from the working car, and finally, the red clamp from the car that was jump started.
Safety Precautions While Disconnecting
While disconnecting, remember not to let the clamps touch each other or any part of the car. This could cause sparks, leading to potential fire hazards.
Post Jump Start Operation
After successfully jump starting your car, your job isn’t over. Your car battery needs to recharge completely, so it’s essential to follow some post-jump starting operations.
Letting the Jump Started Car’s Engine Run
Allow the jump started car’s engine to run for a while to enable the alternator to charge the battery. It’s recommended not to turn off your ignition during this time.
Driving Around for At Least 20 Minutes
After running idle for a while, consider driving the car around for at least 20 minutes. This will ensure the battery has enough time to charge properly.
Common Mistakes to Avoid
Finally, here are some common mistakes that you should avoid when jump starting your car.
Wrong Order of Connecting Jumper Cables
Connecting cables in the wrong sequence could result in serious damage to one or both vehicles’ electrical systems.
Disconnecting Cables While Car Engine on
You should always turn off the engines of both cars before disconnecting the jumper cables. Disconnecting while the engine is running can cause sparks which may be harmful.
Jump Starting a Car with a Damaged Battery
Avoid jump-starting a car whose battery is cracked, leaking or otherwise visibly damaged. This is because damaged batteries can explode when charged suddenly, and can cause serious injuries or even death.
Always remember, safety first. By understanding and following all these essential steps, you can be sure to jump start your car safely and efficiently the next time your battery dies.
