The Battery & Automotive Electrical System


Electricity is a requirement for most vehicles. First and Foremost, all cars with an internal combustion engine need a battery that sends voltage to the starter to turn over the engine. The Battery is then recharged by the alternator when the electrical charge stored inside dips below a certain point. Your Battery will cycle through thousands of engine starts and recharges from the alternator. Once the engine is running, it is the alternator that supplies voltage to your vehicle’s electrical accessories.
