What Is Jump-Starting The Car?

How to jump start a car?

Have you ever wondered what the point of jumping a car was? You may have seen or heard someone mention it while trying to diagnose a battery problem with their car or jump-start another car. 

In contrast, it can be a confusing concept to understand at first, usually only if you are in a situation where this is necessary. 

For those who are unfamiliar with what jump-starting is? Jump starting your car means temporarily connecting to an external power source to your dead battery to start the vehicle.  

It is not a permanent power source but rather a temporary means to get the car started, then you disconnect and go. 

This is done by plugging in jumper cables to the vehicle’s battery terminals that need jump-starting and another car parked close enough so that you can reach those battery terminals.

Next, the other vehicle’s battery is connected to the battery of the car you are trying to start. 

The car will then run normally until the first vehicle’s battery is fully charged; when that happens, the jumper cables are disconnected, and the second vehicle’s battery disconnects from the first.

When Do You Need To Jump-Start Your Car?

You need to jump-start your car if the battery inside your vehicle is dead. There are different reasons why a car’s battery will die, some of which are caused by the driver, and others caused by external factors out of the driver’s control.

You may also want to jump-start your vehicle if there is any failure with the alternator or the starter before you get it into a shop and perform diagnostics. If the alternator or starter fails, you will likely be unable to start your car. 

In such a case, jumping is necessary to either drive it somewhere to get it examined and repaired or to allow you to run some errands while you arrange transportation.
