How to Properly Jump Start a Car

A dead car battery can leave you stranded and be a real headache. But if you carry jumper cables or a jump box in your trunk and know how to use them properly, your problem is solved. Once your engine is running, and if the battery is still good, the alternator will recharge it. If the car battery is bad, at least you can drive to an auto parts store to buy a replacement battery. Often, stores will install a car battery for free.

Jump-starting a car is easy, but you should do it with caution. Since the car battery is located in the engine compartment, where flammable gases may be present, a spark could set off a fire. So while you’re hooking up the weak battery to the live battery in the booster car, you’ll want to do it without creating any sparks. Connecting the jumper cables in the right order will minimize the chance of sparking. With this in mind, here is a step-by-step guide to jump-starting a car.

It’s important to make sure the metal ends of the jumper cables do not touch each other or any metal surfaces on the car until they are connected to the correct battery terminals. This is more difficult than it sounds. Under the hood, most areas are metal. If two people are available to jump-start a car, one person can simply hold the ends of the jumper cables safely separated while the other person moves between the cars, making the proper connections. One person can jump-start a car, but it requires close attention.

Bring Your Dead Battery Back To Life

Your car battery is an essential piece of your vehicle, providing one of the most important functionalities: starting the car. In most traditional vehicle types – that is, cars that run on gasoline – the battery is an SLI, a starting, lighting, and ignition battery. Itâs primarily used to start the engine, but also powers auxiliary components of the automobile including the lights and radio. Once the engine is running, the majority of the energy used to power your car is generated by its alternator. But turning the car on is an essential function of the car battery, a function without which the car is rendered pretty useless. When you turn the key and hear some sputtering, or maybe nothing at all, but the engine fails to start, a dead battery is probably the culprit.

A variety of things can cause your battery to die: cold weather, leaving your lights on for too long, or of course, an old or dysfunctional battery. Regardless, a jump start can sometimes do the trick to solve all your battery troubles – or at least get your car started so you can drive it off to the mechanicâs shop and figure out what the bigger issue is. Jump starting your battery yourself requires some special tools and a little bit of knowledge – but never fear, this guide will tell you everything you need to know!

You can jump start a car either using a portable jump starter, or with the help of another vehicle.

The safest order to attach the jumper cables is as follows:

After you have parked the vehicles next to each other, turn off the ignitions, put on the parking brake, open the hoods of the vehicles, and attach the cables.

Once you’ve attached the cables, which we explain below, start the working vehicle and, after about a minute, try starting the car with the dead battery.

If this doesn’t work, leave it running for up to five minutes, but turn the engine off if the lead gets too hot.

Once your car is running, leave the engine running for a couple of minutes to charge the battery.

Then simply remove the leads in reverse order to how you attached them and make sure they don’t touch each other, or any metal surfaces.
