How to Use a Jump Starter Safely

A jump starter is a portable device. It is used to jump-start a dead automobile battery. It is also called the ‘Jump box’. It is used in a vehicle to supply a burst of power to the battery and provide the necessary energy to start the engine.

Jump starters are not a mandatory tool for an automobile but it holds significant importance for a car engine. If you have a portable jump starter in your car, it will help you to start your vehicle even if the battery is dead. A jump starter can be your savior in emergency situations such as your car engine suddenly stopping in the middle of a journey. Rather than waiting for a tow truck or relying on the kindness of strangers, always keep a jump starter in your car. It enables you to resume your journey on the road quickly and safely.

However, using a jump starter is crucial and risky sometimes. So it’s important that you remember some safety precautions before using one. The safety precautions for using a jump starter include wearing protective eye goggles and rubber hand gloves to electric shock. 

In this article, we will enlighten you on how you can use a jump starter and other relevant activities about it. 

Preparing to Use a Jump Starter

Regular Jump starters and Type jump starters are essential tools for starting a dead or weak car battery. Before using a jump starter, you must take preparations properly. Doing will ensure your safety and the proper use of the jump starter. Here are some steps to make preparation for using a jump starter:

Charging the jump starter

First, you must charge the jump starter fully and properly before using it. If you don’t charge the jump starter fully, it will not be able to supply the engine with the required power.  

Identifying the location of the car battery

Then, identify the location of the car battery. Usually, the battery of a car is located inside its engine compartment. Look for a black box with two terminals on top (positive and negative) that are connected to the car’s electrical system.

Understanding the polarity of the battery

Usually, car batteries have two terminals marked with plus (+) and minus (-) signs. They indicate the polarity of the battery. The positive terminal is usually covered with a red plastic cap.

And the negative terminal is covered with a black plastic cap. It is recommended to ensure that the jump starter cables are connected to the correct terminals. If you connect them incorrectly,  it can cause damage to the battery or the jump starter.
