The Do’s and Don’ts of Jumpstarting a Car
The dead battery car is often seen but most people around 90% of drivers have never jumpstarted a vehicle according to the estimation. Even jumpstarting a car is fairly easy, regardless of what type of car you have, it can be dangerous if a few precautions are not taken.
Why Do You Need To Jumpstart A Car?
The most common reason why jumpstarting a car is the dead battery. And the most common reason why your battery is dead is your battery has become discharged and doesn’t have enough power to turn the starter. Batteries can become discharged when you leave lights or other electrical devices on without the engine running. The maximum longevity of a car’s battery is around 5 years if you have a really good battery. A battery that has reached the end of its life might not be able to be recharged enough to start the car the next time it’s needed. If your battery is over 5 years old, this might be the case.
Sometimes when a car sits idle for too long, the battery loses its charge which is the reason why the battery is incapable of starting a car. Also, a faulty battery or events like leaving the headlight could suck all the juice out of the battery. Even a faulty alternator could be the reason why the battery is dead. Whatever the reason might be, the only hope to restart the car is to jump-start it.
But What Is Jumpstarting A Car?
According to Wikipedia, a jump start, also called a boost, is a method of starting a vehicle with a discharged or dead battery. A temporary connection is made to the battery of another vehicle, or to some other external power source. The external supply of electricity recharges the disabled vehicle’s battery and provides some of the power needed to crank the engine. Once the vehicle has been started, its normal charging system will recharge, so the auxiliary source can be removed. If the vehicle charging system is functional, normal operation of the vehicle will restore the charge of the battery.
