Both your 2013 and 2014 MK3 have the smart charging system. The US models have conventional lead acid batteries.So. Stupid question, how can I tell if my focus has the BMS and smart charging system that needs to be reset? Is there something I should be looking for like a sensor somewhere or is a different type of battery than a standard led acid battery? I've got 2 Foci (13' & 14') both will need batteries before the heat of the summer. Thanks for any assistance!
