Chemical Process inside Batteries

Car batteries work by utilizing a chemical process to produce electricity. Inside a traditional car battery, there are six cells containing lead plates and a sulfuric acid solution. The process starts when the acid solution reacts with the lead plates to produce lead sulfate and hydrogen gas.

This reaction releases electrons which flow from the negative terminal of the battery to the positive terminal through a circuit. As the battery discharges, the lead sulfate and hydrogen gas build up on the plates and the acid solution becomes weaker. To recharge the battery, an external energy source is needed to reverse the chemical reaction and restore the sulfuric acid concentration.

This is done by connecting the battery to a power source and allowing an electrical current to flow in the opposite direction, causing lead sulfate to break down into lead and sulfuric acid. In short, car batteries work by converting chemical energy into electrical energy and back again in order to power your vehicle.

Voltage and Capacity of Batteries

Car batteries are essential for the proper functioning of a vehicle. They are rechargeable batteries that provide electrical energy to power various electrical components of the car, such as the headlights, radio, and GPS.
