Hi all,
I always wondered how a car battery is able to charge cell phones, radio, dashboard and all other things that requiere electricity, and not need to to be recharged for a couple years. Why does it not die out sooner? Can someone please on how it’s able to achieve this curious feat?
Thanks!

The car battery’s main job is to provide power to the starter to start the car. While it can charge things inside the car, or power things in the car such as the headlights or the dash console screens, this is not done for any length of time other than when the car engine is turned off. The battery is recharged every time you drive the car or run the engine by the alternator. The engine generates power and the alternator uses that power to recharge the battery. This happens repeatedly as you drive. The battery is being drained and recharged over and over again.
