I have a 2009 Infiniti G37 coupe with a manual transmission (a dinosaur by today's standards) that I love. Got it used about 4 years ago. It is my wife's car. Low miles when I got it and we still don't put a lot of miles on it but it gets driven almost every day.
For the last two years it has been ruining batteries. Cheap batteries. Posted a while back about terminal clamps not fitting properly. Got a new, cheap, battery. Worked fine for about 6 months then crapped out. Got a middle of the road battery, started to fail immediately, took car to Nissan dealership. They said it was the wrong kind of battery (???). The place where we bought it acknowledged this and gave us a new, correct battery. Now that its cold, it is failing. Had to jump it yesterday.
Car functions properly otherwise. No warning lights. No codes. Wife, who has to deal with all this, called local Nissan dealership that we have dealt with a lot. They said they could run an expensive diagnostic and would still not likely find the problem and said not to waste our money and that we needed to take it to an Inifiniti dealership (an hour away). ?????
Battery takes a jump and charged fully off my trickle charger.
So......questions..........how does one go about finding what is draining the batteries in this car........very slowly and over long periods of time? Seems impossible to me. Second question, would buying a high end, high amp (or whatever spec) battery be likely to change anything or would I just be ruining a more expensive battery? Any thoughts welcome. We love this car and would hate to have to sell it...................you can't find them with manuals anymore.
