ok i've owned this car for about 6 years and a big problem is in the winter if i leave the car outside of the garage or out from a covering the battery has no power and it will not start, but when i put a charger on it, it will start right up. So i replaced the battery a couple years ago and even with a new battery i still had the same exact problem still. So question is why do i have problems starting my car when it gets below freezing?
