A car battery is a crucial component of any vehicle. But what exactly is inside of it?
Inside a car battery, you will find several key components working together. These include lead plates, sulfuric acid, and a plastic casing. The lead plates and sulfuric acid produce the chemical reaction needed to generate electrical power. This power starts the engine and runs electrical systems in the car.
The plastic casing protects and contains these elements. Understanding these components can help you better maintain your car battery. It can also explain why car batteries eventually wear out and need replacing. Knowing what’s inside a car battery gives you insight into its function and importance.
