Everything You Need to Know About Car Batteries

A car battery is a rechargeable battery that supplies electrical energy to a vehicle. It is also known as a lead-acid battery, as it consists of lead plates immersed in an electrolyte solution of sulfuric acid. The battery provides the initial electrical charge to start the engine and supplies power to various electrical systems in the vehicle, such as lights, radio, and air conditioning.

Car batteries are designed to provide a large burst of power for a short period of time, allowing the starter motor to crank the engine. Once the engine is running, the alternator takes over to supply the electrical power needs of the vehicle. However, the battery still plays an important role as a backup power source when the alternator fails or when the vehicle is turned off.

It is important to regularly check and maintain your car battery to ensure it is functioning properly. This can be done by checking the battery's voltage, cleaning the terminals, and making sure the battery is securely fastened. If your battery is more than three years old, it is a good idea to have it tested to ensure it still has enough capacity to start your engine.
