How Does a Car Battery Work?

A car battery is a vital component that serves as the electrical heart of a vehicle, providing the energy needed to start the engine and power various electrical systems. The fundamental principle behind a car battery’s operation is converting chemical energy into electrical energy. Typically, automotive batteries are lead-acid batteries.

When a driver turns the key to start the car, a circuit is completed, allowing electrical current to flow from the battery to the starter motor. Inside the battery are lead dioxide and sponge lead plates immersed in a solution of sulfuric acid, known as the electrolyte. These plates are arranged alternately in cells.

During the discharge (or power delivery) phase, a chemical reaction occurs between the lead dioxide and the sponge lead plates in the presence of sulfuric acid, generating electrons. This flow of electrons creates an electrical current, which powers the starter motor, igniting the engine.

Simultaneously, in the process, lead sulfate forms on the plates. During recharging, the chemical reaction is reversed when the engine runs, and the alternator is operational. The lead sulfate reverts to lead dioxide and sponge lead, replenishing the electrical energy used during starting.

In essence, a car battery works as a rechargeable energy storage device, converting chemical energy into electrical energy during use and reversing the process during charging to maintain its energy reservoir for future starts and to power the vehicle’s electrical components when the engine is off.

What Causes Battery Cable and Terminal Corrosion? 

Battery cable and terminal corrosion are common issues in vehicles and can be attributed to several factors:
