My son has my dart in AZ (I'm in UT) and says the battery died. He's not mechanically inclined so needs help changing it. Went to a shop to have them do it and he was told the dealership has to do it. This can't be right can it? I mean it's just a battery or is there something a little different in this battery install? I can't drive 700 miles to change a battery but I don't want him to get taken either. Is this install just like any other battery install?
