I have a 2015 Si, 45k miles, and I just replaced the battery at the beginning of the season in March, with a duralast gold battery. I usually drive the car on the weekends, but the couple times that the car sat for more than a week, it needed to be jumped. Other than that no issues. I know un used car is not friendly to a battery, but I still feel like it should be able to sit for two weeks and not be dead. Am I wrong?
