There’s nothing more frustrating than getting into your car, turning the key, and hearing nothing but silence. A dead car battery is a common problem, but luckily, it’s a problem that can be solved from the comfort of your own home. In this article, we’ll explore several methods for recharging a dead car battery at home. Whether you’re looking for a classic jumpstart or a new, portable solution, we’ve got you covered.

The Classic Jumpstart

One of the most classic ways to recharge a dead car battery is through a jumpstart. This method requires another vehicle, a working battery, and jumper cables.

The first step is to position the two vehicles so that their batteries are close together. Keep both cars turned off and set the parking brakes to ensure safety. Then, open the hoods of both vehicles and locate the batteries. You’ll want to identify the positive (+) and negative (-) terminals on each battery.

Next, connect the jumper cables to the working battery. Start with the positive cable, attaching it to the positive terminal on the working battery. Then, attach the other end of the positive cable to the positive terminal on the dead battery.

Then, attach the negative cable to the negative terminal on the working battery. Finally, attach the negative cable to an unpainted metal surface on the car with the dead battery. This will help prevent any sparks and ensure your safety.

Once everything is connected, start the engine of the working vehicle. After a few minutes, try starting the dead car. If it doesn’t start, wait a few more minutes before trying again. Once the dead car starts up, let it run for at least 20 minutes to recharge the battery before driving it.

It’s important to note that if the jumpstart doesn’t work, you’ll likely need a new battery or more thorough repairs.

Portable Jump Starters

If you don’t have access to another vehicle or don’t feel comfortable using jumper cables, a portable jump starter may be a good option for you. These devices are battery packs that can be used to jumpstart your car without the need for another vehicle.

To use a portable jump starter, follow the included instructions carefully. Generally, you’ll need to connect the jump starter to the terminals on your car battery. Make sure the jump starter is charged and in good condition before attempting to use it.

It’s important to choose a jump starter with the right specifications for your vehicle. Check the voltage and amperage requirements for your car battery before making a purchase.

Battery Chargers

Another option for recharging a dead car battery is a battery charger. Battery chargers work by sending electricity to your car battery until it’s fully charged.

There are several types of battery chargers available on the market. Some are manual, meaning you’ll need to monitor the charging process and turn the charger off manually. Others are automatic, meaning they’ll shut off when the battery is fully charged.

To use a battery charger, you’ll need to connect the charger to your car battery and a power source. Then, follow the charger’s instructions carefully to monitor the charging process. Make sure to choose a charger with the right specifications for your battery, and always follow safety recommendations when using electricity.

Solar-Powered Chargers

If you’re looking for a more eco-friendly solution, a solar-powered battery charger may be a good choice for you. These chargers use the power of the sun to recharge your car battery.

To use a solar-powered battery charger, place the charger in a sunny spot and connect it to your battery according to the included instructions. Keep in mind that solar-powered chargers may take longer to fully charge your battery compared to other methods.

Be sure to choose a solar charger with enough power to recharge your car battery and follow any included safety instructions.

Jump Boxes

Jump boxes, also known as battery boosters, are similar to portable jump starters. They’re essentially small, portable batteries that can be used to jumpstart your car without the need for another vehicle.

To use a jump box, follow the included instructions carefully. Make sure the jump box is fully charged before attempting to use it, and choose a model with the right specifications for your car battery.

Alternative Methods

In addition to these traditional methods for recharging a dead car battery, there are several alternative methods that some people use. One of these methods involves adding Epsom salt to the battery cells in an effort to revive the battery.

While some people report success with this method, it’s important to note that there are risks involved. Adding the wrong amount of Epsom salt can actually damage your car battery further, and there’s no guarantee that this method will work.

If you’re considering alternative methods, be sure to weigh the risks and benefits carefully before attempting them.


There are several methods for recharging a dead car battery at home. Whether you prefer a classic jumpstart or a more modern solution like a portable jump starter, the key is to follow safety recommendations and choose the right method for your specific situation.

Remember, a dead car battery can be a frustrating and even dangerous problem if you’re stranded. By knowing how to recharge your battery at home, you can save time, money, and hassle.

No matter which method you choose, make sure to prioritize safety and follow any included instructions carefully.
