Idling your car to charge its battery is less efficient than driving, but if necessary, it should be done for at least 5-10 minutes. However, for best results, driving your car for 15-30 minutes, especially at highway speeds, is recommended. This helps ensure the battery is adequately charged without causing unnecessary wear on the engine. If the battery is frequently dying, it might be time to test its health or consider a replacement.
