To simply put, the battery won’t recharge itself – it’s there to help start the car and also provide power for the electronics in the car when the engine is turned off.
Moreover, batteries don’t produce energy – they only store it. The main function of a battery is to power the starter motor, allowing the car’s engine to start.
And when an engine runs, the alternator also runs, which charges the battery. So, no – a car battery doesn’t and can’t charge by their own.
Basically, it is the alternator that charges the battery itself. Once the engine is running, the alternator take charge and provide power for the entire car’s electrical system.
Also, having a dead battery is unavoidable, and this fact just proved it. But that’s nothing to worry about. You can always recharge a dead car battery with a jump from another car battery.
