I am in Texas ,my car stumbled when turning on recently.. I went and had a shop check the OEM battery and it is still putting out 700 CCA vs the original 760.
After researching this, I just recently found out that my battery tender is likely the wrong type and that the car should have an AGM battery.
However.. despite the climate, and the fact that my car does remain on the charger a lot.. I just went on a trip to a track (high plains raceway) in Colorado from Texas last weekend and the original battery worked flawlessly...
