How Car Batteries Are Charged When The Engine Is Running?

Like our wallets, batteries are storage, and no matter how much they got, the amount that they can offer will always come from a source. They don’t have the ability to generate the charge or money.

If a wallet that can generate money is invented, all of us will surely buy it, right?

When it comes to automotive batteries, the source of energy that they store is the alternator of the vehicle. It is the component of the car that generates the AC current to charge the battery by converting the mechanical energy of the crankshaft to electrical energy. That is how the car recharges our automotive batteries.

When it comes to dead batteries, they won’t be able to receive and store the charge even if the alternator is perfectly fine. In a case like this, the options you will have is to get a new replacement or attempt to revive the battery. ​

Proper Ways Of Manually Recharging A Car Battery!

Charging the car battery while the engine is running is the automatic way of recharging an automotive battery. If the car’s alternator is failing or busted, the battery won’t be able to take or receive enough amount of current to get it charged. However, there are several ways you can do to charge your car battery manually.

 To find out about these methods, they are listed below and explained below.

・Using A Battery Charger - One way of manually recharging a car battery is by using a device specifically designed to charge an automotive battery. With a car battery charger, all you have to do is to connect the cables to the right battery terminals of your automotive battery then start charging.

Most of these chargers are built to be portable to allow drivers to bring them all the time, but there are also chargers that you can use at home. The older ones which are not yet equipped with the sophisticated features that the new ones offer today.

・With A Speed or Trickle Charger - Same as using a battery charger, you can also charge a car battery by using a speed or trickle charger. However, this method will require you to place the device on a stable surface.

From there, you will have to connect the cables to the respective battery terminals of the car battery. Then plug the device into a power source then select the mode of charging before turning the device on. Once the device is turned on, you can leave it to until the battery is fully charged.

・Utilizing Jumper Cables - In this method, you are going to charge your car battery with the help of another car’s battery. You are going to use the jumper cables to connect your car battery to another charged battery then start your engine.

That way, the electrical system of your vehicle will start to function and charge your car battery. Just make sure to connect the right polarity of the batteries and then make a secured connection to make sure that your battery will take charge efficiently.
