Imagine what would happen if you are in the middle of nowhere and after hours of fun, your car battery suddenly died. Well, to avoid this scenario, jump starters are always handy. In case of any automotive emergency, owning jump starters in your vehicle’s kit ensures you peace of mind.

What are Jump Starters?

A jump start is basically an external power booster. It consists of two wires with clamps on both ends. Two connections go in the booster device and clamps are connected with discharged battery terminals. Then, a powerful electrical jerk runs through the device to charge the battery up.

In other words, you can say that the external supply of electricity recharges again the disabled vehicle’s battery and gives more power needed to crank the engine up. In this article, we will discuss details about jump starters and review the very best on the market.

First of all, different cars need different voltages to charge dead batteries. There are multiple types of jump starters available and some provide less voltage and some high voltage. One important thing to keep in mind that different vehicles have different electrical systems. For instance, heavy vehicles such as huge trucks or large vehicles with diesel engines may use 24-volt electrical systems.

Remember that trucks usually have a 24-V supply using two 12-V automotive batteries in series. Therefore, it’s possible to jump-start a vehicle with a 12-V electrical system using only one of the two batteries.

On the other hand, vintage cars may have 6-V electrical systems or may connect the positive terminal of the battery to the chassis. The ways intended for boosting 12-volt, whereas negative-ground vehicles can’t be used in such cases. Hybrid vehicles usually have a very small 12-volt battery system which is unfit for sourcing a large amount of energy needed to boost a conventional vehicle.

Most of the jump starters have different amp settings. Even though most models are between 400 to 600 amp, some of them range from 300 to 3,000 amps. Most often, that is quite enough for most people’s cars.

But without a doubt, a compact battery jump-starter has become a must-have auto accessory. This is because the lithium-ion battery technology allows a charge to stay longer even for a year. So, it’s reliable and won’t take much of your car’s space.

After explaining what are jump starters, we will focus on V8 engines in this post. V8 vehicles have a large engine that needs a high volt jump starter to crank its engine. However, these jump starters are not just for V8 but also can be used for any type of car battery.

Now, we have gathered the best jump starters this year so you can purchase the ideal one. Let’s jump in!

How to Use Jump Starters?

Since we spent most of our time in our cars, it’s best advised to know the basics to maintain your car. We recommend reading the vehicle’s manual first to fully understand the particularities that your car model has. But for those who are not familiarized with jump starters and don’t fully know how to use them, we’d like to provide important information. Since we’ve reviewed the best v8 jump starters for you with the hopes you find the ideal one, now you can review or refresh how to jump-start your vehicle if needed.

It’s widely recommended to have in your car the following items in case there’s an emergency:

  1. Make sure the owner’s manual is always secure in the glovebox.
  2. Long-cabled jumper starters. Above we have included reliable jump starters with long cables fit.
  3. Heavy duty or disposable gloves in order to ensure protection.
  4. If possible, always keep a flashlight with back-up batteries.
  5. Disposable coveralls are also recommended to have in your car in order to protect your clothes.

To jump-start a car, be sure to be with someone else who can provide help and a vehicle to jump the dead battery. Please, keep in mind to use your discernment when soliciting support from strangers. Don’t trust anyone you don’t feel comfortable around with and please, be sure to phone a trusted person to let them know exactly where you are and what’s going on; or send them a pin location.

Before you and the other person who’s helping begin, here are a few things you should be warned about first:

Don’t jump a frozen battery or any battery that is cracked. Leaking or cracked batteries can’t be jumped because it’s dangerous. It’s best to purchase a new battery.

  1. The battery shouldn’t be dry. Verify the individual cells for fluid levels and if needed, add water respectively.
  2. Check an owner’s manual for details and warnings about jump-starting your vehicle or any particular vehicle.
  3. Make sure there is no corrosion. Corrosion is usually white or greenish powder around the cells on the battery. If there are signs of corrosion, clean it off with a wire brush, aluminum foil, or anything you have at hand. However, be careful because these chemicals can damage your skin.
  4. Cover your nose and mouth to avoid breathing in the dust since it can irritate your lungs.
  5. And lastly, once the cables are hooked up don’t allow any of the clamps to touch. Each person must hold an end of the cables and keep the two clips separate.
