Your car battery isn’t the powerhouse you might think. Many people think it’s the car battery that powers the electrical components while you’re driving. It’s actually the alternator that makes the electricity for your car. The battery starts you car and provides power to the electrical components when the engine is off. For example, the car battery keeps the digital clock running when your car is turned off. Understanding how the alternator works can help you when you’re having problems with your car or motorcycle battery.

How Does an Alternator Work?

The alternator is a component of your car’s engine about the size of a coconut. It takes the mechanical energy from the belt and rotors and transforms it into electricity that powers your windshield wipers, headlights and car components that use electricity. The alternator also charges the battery. The power from the alternator flows into the battery, allowing the battery to use that power to recharge. Alternators generate a lot of heat when they produce electricity. Older alternators were made with an external cooling fan. Technology has improved. Newer alternators have an internal fan.

It takes between 13.5 and 14.5 volts to keep your battery charged. Alternators with bad diodes can cause your battery drain. Finally, old batteries drain quicker than newer batteries. You should be replacing your car battery every four to five years. As the battery gets older, it may not hold a full charge when the alternator isn’t running. Your battery should have a manufacturing date on the case to let you know how old it is.
