Does Your Car Battery Charge At Idle. When the engine is not running the battery voltage is usually somewhere between 124 V and 126 V. Just go get a battery from KmartWalmart or something like that it wont cost more than 30 bucks and in teh long run will be better.
So before I go freeze to death in this -39 pure Canadian cold to replace my alternator does anyone have any final suggestions. As I said before it is inefficient a waste of gas and causes wear and tear on your vehicle. You may have been sitting in your car with it running thinking if your car will keep charging your car while it is currently idling.
You will need several hours to recharge your car battery completely.
The good news is that yes your car battery will charge when idling. If your car engine is at the idle state it takes a considerable time for the car alternator to charge the battery. The short answer is yes but it may take several hours to fully charge your battery wasting fuel. This can happen when cars are running idle even while charging your phone for a long period of time or with your car accessory equipment on in the background.
