Assuming the alternator, engine, belt, and battery are all in working order, then yes, a car battery will charge when idling. The only caveat is that it doesn’t really “charge” that fast. This is solely due to the fact that the engine doesn’t have a load on it when your car is simply idling.

How long should I let my car idle to charge the battery?

Idling: it’s far from ideal.
