How Many Amps Is A Car Battery?

How many amps does a car battery have?

An automotive power cell, commonly known as the car battery is one of the most important component of an automobile. Its main purpose is to provide the cranking amp the vehicle needs to ignite the spark plug and start the engine.

The battery is also the one that powers all the electronic components of the vehicle when the engine is not running. If this component is well-maintained, it will greatly enhance the performance of the vehicle.

This article will provide you a detailed overview of a car battery. Giving you all the basic information that you have to know about a car battery.

Information about how many amps is a car battery and how it is related to the size of the vehicle. It will also guide you in choosing the most suitable power cell that will perfectly suit your car.

To expand your overall awareness with regards to car batteries and how they work. Being familiar with this information will help you in situations where you will need to replace your car battery, and you need to choose the best suitable one to ensure better car performance.

The Typical Amps Value Of Average Automotive Power Cells

A car battery’s amp rating mainly refers to its electrical storage capacity or the maximum amount of electric current that it can store. Typically, most car batteries have an amp rating that ranges from 550 amps up to 1000 amps.

However, when it comes to automotive batteries, people are more concerned about the Cranking Amp (CA) and Cold Cranking Amp (CCA) ratings. A lot of consumers base their choice in these two battery ratings.

The Cranking Amp rating is the amount of current the battery at 32°F can deliver for thirty seconds and maintain a minimum of 1.2 volts per battery cell. In layman terms, cranking amp rating is the amount of power the battery can provide to start the engine in normal climate or temperature.

While Cold Cranking amp rating refers to the amount of current, the battery at -4°F can deliver and maintain 1.2 volts on every battery cell. Or simply the amount of power the battery can deliver to start the engine in cold weather or climate.

Does The Vehicle Size Matter In Selecting The Suitable Battery?

When it comes to choosing a battery that will suit a vehicle, the amp rating that you need is not determined by the size of the vehicle. Deciding what’s the amp rating the battery should have will be primarily based on the total electrical load of the vehicle.

You have to base your decision on the how much ampere your car needs to start its engine in both normal and cold weather as well as overall electrical requirement of your car.

If the amp rating of the battery is lower than the vehicle’s overall electrical requirement. It simply means that the battery doesn’t have the capability of supplying the power the car needs. So, in this case, we can say that size doesn’t matter.

How To Choose The Right Auto Battery That Will Suit Your Car

Choosing the right automotive battery that perfectly suits your car will provide a lot of great benefits. By carefully choosing the automotive power cell with a reasonable and affordable price tag and at the same time satisfy all of your needs.

Buying the car battery that perfectly suits your car enhances the performance of the vehicle allowing you to enjoy smoother drives and better experience.

However, to get the best suitable battery for your car will require you to consider the significant aspects listed below.

● Battery Size – The first thing that you have to consider is the size of the battery. You have to make sure that the battery that you will buy has the exact size and specifications that will fit your car’s battery tray. Failing to do this will force you to return the battery and replace it with the right size, wasting precious time and even money.

● Cold Cranking Amp – In choosing a car battery, you want to look for the ones that are capable of providing the amount of power to start your engine. It also has to be capable of starting your engine in cold weather where it will have to work harder and provide enough amount of current.
● Reserve Capacity – The battery’s reserve capacity refers to its standing power. This is the specific amount of time that the battery can provide the power the car needs when the alternator is not working. It determines how long the battery can stand on its own without receiving a charge.


Finding out how much amps is an auto battery will tell you how much current the battery can store. Amp rating determines the entire electrical storage capacity of the battery which simply means the maximum amount of energy the power cell can store.

However, in choosing an automotive battery, the Cold Cranking Amp is more important than its amp rating. This is because the CCA determines the battery’s capability of starting the car in cold and demanding weather.
