Will using the car air conditioner drain the battery?
1 Answers
Turning on the air conditioner while the car is idling will not deplete the battery. Here are the relevant reasons regarding battery drainage from air conditioning: 1. Idling does not consume electricity: The idea that idling can drain the battery is fundamentally incorrect. As long as the engine is running, the alternator continues to work, so there's no need to worry about the battery being depleted. 2. Air conditioning cooling mechanism: The air conditioner's cooling function is powered by the engine driving the air conditioning compressor. The only electrical component is the blower fan at the vents. During idling, the alternator remains operational, so there's no concern about the air conditioner draining the battery while the car is idling.
