We all know what a car battery is, and where it is. And we certainly know when ours isn’t working right! But many women don’t understand what a car battery actually does. Car batteries are just like the batteries we use in other devices, our remote controls, our cell phones, just bigger. In a car, the battery powers the electronic features, and also starts the car.
The car battery kind of works like a self-recharging battery, too. When you turn the key, or push your ignition button, the battery provides a burst of power to start the engine. Once the car is running, the engine’s alternator keeps the battery charged so it will work next time you start the car.
