I live in deep southern Texas right on the border with Mexico and it's still mid 90's most days. Last night we had a cold snap for us anyway, and this morning it is 50 degrees. My 2016 ED has only 5200 miles on it and it works great. I was just surprised that last night the battery was at 89%. With this cold weather the battery is only showing 69% so a full 20 point drop. Is it normal for cooler weather to effect the battery to that degree. Was just surprised.
