How Many Amps Does a Car Battery Put Out?

 There is often some confusion around the question, "how many amps does a car put out?".  

This is because it heavily depends on the car, as not all cars are equal. 

Throughout this article, we'll try to guide you through how many amps an average car puts out. But, keep in mind this could be completely different for your car, or any other car.

What Is an Amps and How Do They Work?

When we are talking about amps, we are referring to the amount of electricity in a battery.

Cars use quite a lot of amps compared to other smaller electrical devices, as they need more electricity. But, the battery of a car is also usually quite powerful, meaning you won't have to recharge your car battery too often. 

How Many Amps Does a Car Battery Put Out?

How many amps a car puts out depends on the type of car. For this, we use a measurement called amps hours which allows us to measure how long the battery will last between charges. 

If a battery has amp hours of 100Ah, it would mean that it can put out 5 amps for 20 hours. If you were to use 20 amps, then it would last 5 hours. 

So to find out how many amps your car puts out, you need to find the amp-hours, and then you can calculate how many amps your car puts out. 

How Fast Does a Car Battery Charge? 

In general, car battery chargers will have a power of around 2 amps. And, most car batteries will have a capacity of around 48 amps when fully charged.

This means it will take around 24 hours to fully charge the battery. It makes sense to use a lower charger like this, as then the chances of your battery overheating are extremely low. Other chargers deliver more amps quickly but watch out as these can also overheat your battery.
