Can a car charge the battery while idling?

[DelAriel]

Yes, a car can charge the battery while idling. When the car is idling, the charging system supplies power to the battery. This is because after the engine starts, various components such as the car's computer, processor, sensors, wiring, and relays consume battery power. If the charging system fails to recharge the battery during idling, the engine would not be able to idle properly. As long as the car is running, if you see a battery-shaped indicator light on the dashboard that turns off immediately after the engine starts, it indicates that the charging system is functioning normally and is actively charging the battery.
