Hello, How To Connects Friends! Today, we’ll be discussing an essential skill that every car owner must have: connecting jumper cables. A dead car battery can happen to anyone, anytime, anywhere, and knowing how to jump-start your car is crucial, especially in cases of emergency. So, let’s get ready to jump-start your car and be on your way in no time! 🚗💨

What You’ll Need 🛠️

First things first, ensure that you have the necessary items to jump-start your car:

A pair of jumper cables
A second car with a good battery
Work gloves and safety glasses

The Dos and Don’ts 🔍

Before we jump into the steps, let’s start with some essential dos and don’ts to ensure your safety:


👍 Use the correct jumper cable size. It’s vital to ensure that the gauge of the cable is appropriate for the size of the battery. This information is indicated in the owner’s manual. A wrong size cable may cause irreversible damage to the car’s battery and electrical system.

👍 Put on safety gloves and glasses. Batteries contain corrosive material that can damage your skin and eyes. Always prioritize safety.

👍 Turn off both car engines, headlights, and stereos before connecting the jumper cables. You don’t want to cause any electrical surges that can harm your car’s computer or audio system.


👎 Allow the clamps to touch each other while the cables are attached to a power supply. It can cause a short circuit and damage the batteries or electrical system.

👎 Connect the jumper cables backward. Always ensure that the positive (+) and negative (-) clamps align with the corresponding battery terminal.

Step-by-Step Process 🚀

Now that we’ve established the basics let’s jump-start your car:

Step 1: Connect the Positive Jumper Cable

Find the positive terminal for the dead battery, which is usually marked with a “+” sign. Next, connect one end of the red jumper cable to the positive (+) terminal of the dead battery. Then connect the other end of the red jumper cable to the positive (+) terminal of the charged battery.

Step 2: Connect the Negative Jumper Cable

Locate the negative terminal of the charged battery, which is marked with a “-” sign. Then connect one end of the black jumper cable to the negative (-) terminal of the charged battery.

Here is where things get a bit tricky. Instead of attaching the other end of the black cable to the negative (-) terminal of the dead battery, it’s best to attach it to an unpainted metal surface or engine block in the engine compartment of the car with the dead battery. This will serve as a grounding cable and prevent any sparks from occurring.

Step 3: Start the Charger Car’s Engine

Start the charger car’s engine and let it run for about 2 to 3 minutes. This will provide power to the dead battery and allow it to build up a charge. Keep both car engines off while performing this step.

Step 4: Start the Dead Car’s Engine

Now is the time to start the dead car’s engine. Try to start the engine, and don’t be alarmed if you hear a weak crank. If the engine doesn’t start, wait for a minute or two, then try again. Once the engine starts successfully, let it run for a few minutes to ensure that the battery has been charged adequately. Then, carefully remove the jumper cables in the reverse order that you connected them.
