"It is important to cover some basics of how an alternator works. The alternator is located on the engine itself and plays the critical role of providing power to the battery. It keeps the battery continuously charged and the car’s electrical and computer systems up and running.

Several factors can impact the lifespan of your alternator, including the quality of the part, the overall condition of the vehicle, and how many electronics are being used.”
