@asemaster and @tester that is why I always use either my memory saver, that plugs into obd2 or cig lighter, Daughter needed a new battery, and said lets go to auto whatever for a free new battery install, Do you have a memory maintainer, not sure the guy says, I said can you check? after a bit of fumbling around and disconcerting looks they found one, and the guy who did it said this is a really good idea, we replaced a battery in a honda last week, and had to buy a new computer for it, transalate as you wish.
