Does The Car Battery Charge When Idling. When choosing a car charger bear in mind that fast chargers will do the job more quickly but may overheat the battery and the slower charging trickle-down varieties deliver a charge that will not overheat the battery. Charging while idling will charge your battery but slowly.
IF the battery and charging system are in good condition and the car starts up normally meaning within a couple of seconds for any modern car in good condition it takes only a couple of minutes or so to replenish the small amount of energy stored in the battery that was used. Of course this can be done if there are no damages to the battery and if the car battery can still hold a charge. Again I encourage you to watch the video above this answer will make more sense.
Yes the car battery charges while idling.
If all the electrics lights heated screem etc are off then just idling it will charge the battery. This results in the alternator sou. When the engine is running the armature in the alternator spins. That is being turned by the engine crankshaft.
