2014 C-Max Energi
Not sure of build date (where do I find that?)
Drove to relative's house 200 miles away for Christmas.
10 degrees outside. Did not plug car in.
When we started to pack the car to leave, the liftgate wouldn't open easily.
Got in car to start it, and no sign of life. Screen said "System shutting down to save battery."
No warnings at all via MFM. None.
Turned off all possible functions in car. Waited a few minutes, and car started.
Plugged car in upon arriving home. Stayed plugged in for 2 days.
Tried to start it; same issue as before. Plugged it back in for a minute (I had unplugged it as usual to start it), sat in the car with dash activated, unplugged the car, and it started right up.
1. I know there's another thread or two about this issue. Given the age and mileage of my car, is it likely that the battery is truly dead, or should I look for a different root cause?
2. Someone remind me...how can I check the battery capacity without a voltmeter? Something about starting it while pressing the OK button????
As a side note: on another thread, someone indicated that if left running and you exit the car with the key, the car will shut off after 15 minutes. I can tell you this did not happen for me (and I'm glad it didn't). I left the car running for 2 hours while I was inside an Urgent Care clinic (because I was in a bind and did not trust the car to restart), and I came back out and it was still on, silently.
Thanks in advance for your help/advice.
