Car Battery Charging While Idling
Car batteries charge while idling. The alternator produces enough power to charge the battery when idling. The battery charges as long as the car runs. But it charges slower than when driving.
- Charging rate while idling depends on alternator output, electrical load, and battery condition. Turn off unnecessary electronics to speed up charging.
Battery Charging Efficiency
