Lead acid batteries are the most common types of batteries used in automotive. They play an important part in starting the vehicle and supplying current to the whole car. In addition to this, there are many other functions that are performed by the car batteries. 

From being the powerhouse of the car to powering the serge regulator, car batteries have a lot of functions to do. Later in this article, we will explain the top 4 functions of a car battery that will help you understand the true work a battery performs for your car. 

It is the PowerHouse of the Car

You may not think of a car battery as an important component of the vehicle, but it is actually the powerhouse of your car. The lead acid battery comes in a cubic shape container that contains a chemical mixture and positive and negative plates inside it. 

These plates help ignite the current, and the mixture acts as an electrolyte to provide a positive and negative charge to the plates. The capacity and strength of the plates vary from battery to battery, and these factors determine its price. 

Lead acid batteries store energy for later use and provide power to the whole vehicle. This is the reason; it’s called the powerhouse of the cell. 

It Powers the Ignition System

The ignition system of the vehicle is what starts the vehicle, and automotive batteries are what power this system. As soon as you press the start switch, it sends the signal to the batteries to ignite the system. 

The batteries then generate a high voltage that is sent to all spark plugs to ignite the fuel. This ignition happens in the combustion chamber, and the vehicle is started. This whole process is dependent on the batteries to generate current to start the vehicle. 

That’s why it’s recommended to keep your batteries charged at full potential so that they can ignite the engine in every weather condition. 

Battery is the Heart of the Car’s Electrical System

Along with powering the vehicle and igniting the engine, automotive batteries also have another important function to do. They are used to power a vehicle’s electrical system. There’s a lot of electrical equipment in the car that needs to be powered by the battery. 

Along with existing components like horns, lights, indicators, and wipers, the windows, power steering, side mirrors, and stereo are also powered by an electrical system. This has increased the need for automotive batteries in vehicles. Lead acid batteries handle all these things single-handedly while supplying power to the car. 

It Acts as a Voltage Regulator

The function of the battery does not stop once it has ignited the engine. The battery keeps working even when the vehicle is running. After you have turned the vehicle on, the battery is busy generating power and regulates voltage throughout the travel. 

Without the battery, the voltage may spike suddenly and cause a lot of harm to your vehicle. The battery also works to absorb the excessive voltage that other car parts may generate.
