Should you observe an aged appearance or white corrosion around the terminals, a battery test would be advisable.
Why do cars need a battery?
Cars need a battery because it is an essential component of the electrical system that powers the vehicle. The battery provides the electrical power needed to start the engine and to run the various electrical systems in the car, such as the headlights, the dashboard lights, and the radio.
The battery is also used to store electrical energy that is generated by the alternator, which is a device that charges the battery while the car is running. This stored energy is used to power the car’s electrical systems when the engine is not running, such as when the car is turned off or when the engine is not running at high speeds.
Without a battery, a car would not be able to start or run its electrical systems, which would make it difficult or impossible to use. For this reason, it is important to maintain the health of the battery and to replace it if it fails or becomes damaged.
