The car has been taking longer then usual to start in the mornings for past week or two so I knew the battery was on its last leg. It wouldn't start at all yesterday and I had left nothing on for it to drain so I guess its dead. I replaced it with Kirkland(costco) size 11 yes'day and so far its fine. Would it be dead in jsut 3 years? I remember the battery in my maxima lasted me more then 8 years.
