Can a car battery recharge itself?

I know you can jump a car battery, but I was wondering if there’s any way the battery can charge on its own due to the electrical workings in the engine. Can a car battery recharge itself?

Unfortunately, the short answer is no—but how great would that be!
Most car insurance policies renew automatically, but car batteries aren’t able to recharge themselves. Car batteries store energy, but don’t actually produce it themselves—the energy is produced externally.
The battery needs an external power source in order to work. When the car is running, the battery is charged by the alternator, which powers the car’s electrical accessories. If the car battery dies and you can’t turn the car on, you’ll need to jump-start the battery to get it working again.
