Will Leaving A Car Running Charge The Battery. In the case of petrol engine cars it also helps to prevent engines from flooding with fuel. How long should I leave my car running to charge the battery.
Yes your Vehicle Battery Charge while it is inactive and this is due to the alternator built into the battery. But there are a few cases where it is probably wise to remember to unplug them each time. Answered 1 year ago Author has 19K answers and 8348K answer views.
If your car battery has never been dead then you must drive the car most of the times.
While you are driving the car the alternator is charging your battery. The alternator will continue to charge the battery as long as the engine is running. My hunch is that more activation energy is required to start a sitting car than the amount of energy that can be gained after a car runs at idle for a few minutes. Leaving the headlights on when the car is not running will drain a significant amount of the batterys charge.
