My battery was new 9/2020, came out yesterday morning and it is dead, registering 1.7V. Finally got the trunk open and got a new battery via my warranty on the old one, no additional cost. Everything lights up etc., but the car won't start. I have a red triangle showing and an image of a battery showing? Can't seem to find any help in my owner's manual. I really don't want to tow it to my mechanic or even the local Ford dealer money is a bit tight right now, hoping to getting it going on my own. Any help??
