A car battery is a rechargeable battery that supplies electric energy to a car. Its main job is to start the engine, but it also provides power to electrical components when it is not running. The battery stores energy in chemical form and converts it to electrical energy when needed.
When you turn the key in the ignition, the battery sends a burst of power to the starter, which starts the engine. Once the engine runs, the alternator takes over, providing power to the car's electrical systems and recharging the battery.
A typical car battery comprises six cells, each producing 2.1 volts for 12.6 volts. Each cell contains a positive and a negative plate, separated by a piece of plastic. The positive plate is made of lead dioxide, while the negative plate is made of lead. These plates are submerged in sulfuric acid, which acts as an electrolyte.
When the battery discharges, the sulfuric acid reacts with the lead dioxide and lead plates to create lead sulfate and water, releasing electrical energy. The process is reversed when the battery is recharged, converting the lead sulfate back into lead dioxide, lead, and sulfuric acid.
The construction of a car battery is quite robust and can withstand harsh conditions under the hood of a car. Here’s a breakdown of the main components:
