Hi, new here...I have a 2003 Infiniti Q45. I am about to sell it and trying to get it all squared away maintenance wise! When I first got the car from my brother-in-law, a year ago, I replaced the battery...I had to do it in a hurry as the car was dead and went to Walmart to get one, not too expensive...but whatever I could get. This is what is going on: car has been maintained perfectly by brother-in-law. About 6 months ago, got in car and it would not start. No "clicking", just nothing...lights on however, all power stuff working. Then I would try again and it would work perfectly. I can go for a month without it doing it...then it happens again. Once I cleaned the remote key and it worked fine...then it starts doing it again. Now I don't want someone to charge me for something I don't need...done enough reading...could be 1) battery? 2) starter?, or 3) ignition needing a part?, or anything else? Car runs great, no other problems at all. Is there such a thing as my battery not being "ENOUGH" for this car? Thank you kindly for your help and insight.
