I'm older and don't drive much in my 2015 BMW (9000 miles in 4 years) so had problems when he told me it won't charge etc. Now I connect this when I it do. Don't use it and there will be no more problems! Automatically knows which battery, etc. is being charged, and then just does more when the battery gets low. Seems only necessary in winter.
