We have a 2013 Cmax Energi that is about 6 years old. We bought it while Ford was closing out the 2013's and got a pretty good deal on it. When all this Covid crap started, I stopped driving it and it stayed in the driveway for over 3 months. Last month when I started driving to work a few days a week, the first time I went to start the car it was dead as a doorknob! This has happened a few times, but normally after I jump start it, then drive it a bit, everything returns to normal. I just figured it was dead because I had not driven or started it in 3 months. Last week when I was going to take it to work, it was dead again. I connected our portable charger to it to jump the battery, and it started. I only let it run for about 5 minutes or so as it was really hot outside, and did not drive it. After I disconnected the battery, it went dead again. This morning I went out and the car was dead again, and I put a multitester to the terminals under the hood where I attach the jumper cables to, and it registered 2.1V. After jumping and starting the car, I drive it for about a mile or so, and after turning off the engine, the battery tested at 12.6V. The car started and the electronics seemed to work afterwards also. I will see how it is later today, but my big question is, is our 12V battery going bad? We thought we had it replaced last year, but we cannot find the receipt. Last year we had an issue where the car was dead almost every time I went to start it, and even when it did start, some of the electronics in the car like the audio system and electric windows did not work correctly. I saw on another post how to get to the battery, but apparently to get the date on the battery it has to be removed, and I just do not feel comfortable doing that. Any ideas???
Yeah! Something strange lke this happens to my 2013 Cmax. Every few weeks, I wake up to a dead battery. I spoke with a couple of Ford experts about it and they told me hat the problem is a random parasitic draw. And that it is difficult to find where the draw is randomly occurring. So I bought me a jump pack. After I jump the battery, the car works fine until it happens again.
