No a car battery does not have the ability to recharge itself. To simply put the battery wont recharge itself its there to help start the car and also provide power for the electronics in the car when the engine is turned off.
This of course only gives a brief surge of power if the battery had been previously drained.
A car battery can do a lot but it cant charge itself. No motorcycle charging system will recharge a battery. So with that said can a car battery recharge itself. A car battery can do a lot but it cant charge itself.
