Does Driving The Car Charge The Battery. Risk To Battery Charging By Driving. Low voltage battery is mostly experienced in vehicles that have not been used for a long time.
The amp used to charge your battery will depend on the type of your battery. Older cars do need higher revs so the alternator will provide sufficient energy to keep. This will make it ready to receive increased amperage from the alternator.
The answer is YES yes the car battery does charge while the engine is idling.
Any other method is what you may need to use in the case of an emergency or when your battery is dead and you need to jump start the car. That is why short trips wear batteries out they never get back up to full charge and the drain from starting the car. Driving for at least half an hour will continue to charge the battery. While driving the power from engines goes to the battery.
