The 12v battery in our 2013 FFE is dead, according to my multimeter. Not surprising since it looks to be original (we bought the car used in late 2015). I'm assuming that replacing it is similar to an ICE car and something I can do myself without difficulty, but you know what they say about assuming! So, is there anything special I need to know about the 12v battery in the FFE, or can I just swap in a new one without a trip to the dealer? Thanks in advance!
