Dead battery on 2012 edge se

Any other electrical issues with the Edge? Sometimes, if the Battery Monitoring System is not reset when a new battery is installed, the charging does not occur properly because the computer thinks it is still dealing with the old battery. Best/easiest way is to have the dealer reset the BMS.

 

Sometimes Motorcraft batteries give up the ghost early, it happens even in their Tough Max offerings. Try having it loadtested with a digital load tester.

 

Another possibility is that the alternator is not charging properly, and if you track the voltages while the Edge is running, it should be between 14 and 14.5V consistently, preferably towards 14.5V than not. With engine & every accessory off, voltage should be about 12.6V or so.

Like what "WWWPerfA_ZN0W" stated, may be the Battery Monitoring System requires resetting. There is an another to reset it yourself:

 

From this post:

Carry out the Battery Monitoring System (BMS) Reset using the scan tool after the battery is connected. If the BMS Reset is not carried out, it takes approximately 8 hours for the Body Control Module (BCM) to learn the new battery state of charge. During this 8 hour period, the vehicle must be undisturbed, with no doors opened or keyless entry button presses. If the vehicle is used before the BCM is allowed to learn the new battery state of charge, engine off load shedding can still occur and a message may be displayed."

I had a battery that was dying and had no battery light and everything was seemingly OK, but a close scrutiny of the charging system revealed that the alternator was putting out just enough charge to say it was working and if you do not REALLY REALLY investigate it and test it hard you will not find the problem turned out the voltage regulator could charge under idle but when a load was placed on it it charged but not enough to keep up with all the accessories running. This video shows the issue.

Ok just had my edge at ford dealer and they said it was dead battery and my capless fuel filler was not letting pressure escape or something so they replaced battery and fuel filler
