So it is all about how you charge the car 2amp or 10 amp switch on the leaf button. generally I can charge it at home at 4pm and be fully charged by 5am and I drive 27 miles every day to work. I would plug it in at work (630am) and it would be fully charged by 3pm. it is also how you drive. 80- mph will drain your battery faster vs 65 to 67 mph and up hills will make a difference as it is more power required to pull. quick charge is the way to go.
