That document says it is not charged until it has been down to 40% for 48 hours when the car is not on. I don't believe it is good for a battery to be discharged to that level in cold weather on a regular basis.Theoretically, shouldn’t matter, because 12v batt charges whether plugged in, driving, unplugged in garage or whatever so long as HVB is over a certain percentage charge.
Have a look at attached from page 4, very interesting!
