I am going to be changing the battery in my Corvette soon. A quick couple of questions for the group, Usually I keep my battery tender on the car side of the cables when I pull the battery to keep some power going into the car so I do not loose any of the memory or settings. Is this the right way to do it or does it even matter if I just disconnect and hook up a new battery without doing that. If i just do the disconnect do I have to reset anything when the new battery is installed?
