I have a new 2003 Infiniti QX4. If I let it sit for 3 days or more, the battery needs to be charged .. it will not start. I took it to the dealer and he checked the battery. It checks out good on his meter showing no bad cells and a normal amp/hour rating. According to their policy, they cannot replace the battery because their test unit shows it to be OK. Obviously, by the time I drive it to the dealer it has fully recharged.
As I see it, there are two possibilities: the battery is defective and looses its charge over the 3 day period or something is drawing current over those 3 days. Can anyone advise me as how I can test for both of the above problems.
I could always go over to Costco and pick up another battery for under $50 which would be the easiest thing to do if it were a battery problem. However, I would like to accurately diagnose the problem since I am under warrantee.
