I have no idea, because my Ford dealer has had my car for an ENTIRE MONTH doing testing. Ford engineers now say "normal wear and tear." Mileage was showing 21-22, now showing 13-14. I never paid attention to KWH bc I am a layperson and I just wanted to drive my car and forget about all technical stuff. I was never told ANYTHING about charging TOO MUCH. I am so disappointed in Ford. I am currently on hold with Ford Customer relationship center, I have been on hold for like 30 minutes. And, I know this is a pointless phone call, because if my dealer has had the car a month and done days and days of testing and wasting several cycles of my battery/putting more miles on my car, and they can't get Ford to get a new battery, how can I?
