Will Idling Charge Battery. The answer is YES yes the car battery does charge while the engine is idling. As such this technology may also limit your cars ability to charge at low RPMs.
But it is such a small amount of charge that it will not be able to top off a battery especially a battery that is about dead. My car battery is rated at 590 Cold Cranking Amps which I estimate to be about 60-65 amp-hours based on the work I did in an article here which estimates amp-hours based on cold-cranking amps.

Theyre not expensive and last forever so maybe think about buying one.
The laptop can detect battery type but is not allowing charge. The removal of electrical power from the engine erases idle memory from the PCM the computer where it is stored. Not usually Typically the alternator is not turning fast enough to charge the battery A vehicles electrical system is constantly consuming power while the engine is running at an engine idle the current produced by the alternator is usually not enough to keep up with the dema. Again I encourage you to watch the video above this answer will make more sense.
