Using the cars alternator to bring the battery to a fully charged state when starting from a low charge state(10.0V) is not cost/time effective.The car doesn’t have to be moving,the idle does not have to be high,just “off idle”.A loaded charging system test is done with the engine at 1500-2000 rpm (depending on what manual you use)I dont think your running the car at 1500 rpm in the driveway.The real question is does anything need to be done in regards to the batterys charge and a lack of vehicle use. You will get many opinions,several a week on this forum.It depends on what the parasitic draw on the battery is and how long the inactivity time is,combined with battery health and vehicle storage enviroment.You need to set some tighter parameters to get a quality technical answer.
