An automotive battery is a crucial component of a vehicle’s electrical system, serving as the primary power source for starting the engine and providing electricity for various accessories when the engine is not running. These batteries are typically lead-acid batteries, although newer vehicles may use lithium-ion technology.

The automotive battery works by converting chemical energy into electrical energy through a process of chemical reactions. When the engine is started, the battery delivers a burst of high electrical current to the starter motor, which then turns the engine over. Once the engine is running, the alternator takes over the task of providing electrical power to the vehicle’s systems while also recharging the battery.
