So far on my new battery I have had no problems either but I carefully manage my electrical load making sure
I always push the Start/Stop button twice before locking the car. I also turn off the seat heater once my butt is
warm and turn off the rear window defroster once the window is clear. I trickle charge if the temperature goes down past -15C/0F or if I will be away for two days or more. After reading magnumforc's farewell post today I can't help wondering if two new batteries in the family's
GTs would have solved much, if not all, of his problems.
