I have never charged my battery beyond 90%, and most of the time I don't charge it above 50%. I have an 85D with just under 6,000 miles. This Sunday I am taking a road trip and will do a range charge for the first time. If I time it to finish when I want to leave, how much extra time should I allow to get to 100%? I normally get 29-30 mph of charge on my home charger. Is there a taper on a range charge using a Level 2 charger?
