The car alternator is an ingenious piece of engineering. It takes energy from the motion of your car and turns it into electricity, rather like a windmill. This electricity keeps your car battery charged and your car's electrical components running smoothly. You can thank your alternator for consistent operation of your car's power features, the infotainment system, defroster, windshield wipers, and headlights.
A Constant Source of Renewable Energy
Think about it: without a source of renewable energy, your car battery would just run out of juice and die.
