Forward to December 20, 2021, my AAA battery tested 247/600 during an oil change service. The replacement battery was installed on May 19, 2020. I have been using a battery tender, plugging it in almost every night. I have had no issues with starting since using the tender. I thought the tender would keep the battery charged. There is still a draw on the battery. The battery drain has been a problem almost since the card was purchased on May 15, 2018. See prior post for history.

Did you ever find the cause of the battery drain?

No I did not. Thanks for asking. The Ford Service (Dealer) wants me to have it towed in without restarting (there is a way to put the car in neutral (car manual) if the battery dies). I am not confident the Ford Service could find the cause even then. I have gotten a portable battery jump starter and have put the car/battery on a charger (when not in use) to try to maintain the battery. I am using a Cen-Tech Battery Charger. Use of the charger has only been less than a week. I have been physically turning off the radio, heat/cool and lights when we park the car (not sure this does any good). We also have tried to drive the car more. The Pandemic has reduced the amount of driving we do. If I find an answer, I will post it. This is a very difficult thing to diagnosis from all reports. Ford Service has made a good faith effort to find the cause but the Ford Motor Company has not provided a way to diagnosis this type of issue. My goal is to try to get another year out of the Edge and then sell it or trade it.

I have experienced a series of battery related issues since we purchased the vehicle which I attribute to a parasitic drain. I have had the vehicle checked four times at the Ford Service (Dealership) but they have been unable to determine the cause of the drain. This is the time line of the battery failures and what was done along with some comments: 5/15/2018: Purchase of vehicle 1/14/2019 Mileage 9327: Battery failure occurred in North Carolina. The vehicle had not been driven for two days prior to the failure. AAA Road Service determined that the battery had failed. The battery was replaced by AAA Service as this occurred while we were out of state. I submitted a warranty claim to Ford Service with documentation. The claim was approved and I was reimbursed for the coast of the battery. I think the battery could have been jump started but we had a 625 mile trip ahead and I did not want to take a chance. 5/19/2020 Mileage 26,500 + Battery failure occurred while vehicle was in the garage. The vehicle had not been driven in about 6 days prior to the failure. AAA Road Service was called. The Tech determined that the battery had failed and it was replaced at no additional charge as the battery was under AAA warranty. As the Tech was finishing up, I heard him comment that the battery may not have failed but only needed recharged. 6/3/2020 Mileage 26,581: The vehicle was check by Ford Service. No problems were detected. This was covered under warranty. 11/3/2020 Mileage 32,140: The battery failed in the garage. The vehicle had not been driven in two days. I had the vehicle towed by AAA Road Service to Ford Service where diagnostics were done but nothing was detected. The AAA Road Service jump started the vehicle to get it out of the garage so the system or failing part may have reset. (I should have had the vehicle put in neutral and not jump started it.) 4/8/2021 Mileage 35,960: The battery was in a failure mode but not completely drained. Vehicle was in the garage. Some accessories were powered but there was not enough cracking amps to start the vehicle. I jump started the vehicle and it operated okay. This failure occurred two days after we had completed a 700 mile drive. One would think the battery would have been fully charged. The vehicle was not driven the day before the failure. 4/14/2021 Mileage 36,097: Ford Service again tried to find the source of the battery drain was unable to find anything. Ford Service did indicate the CCA was 543 out of 600 and gave it "Yellow" rating. This battery was about 11 months old. 5/3/21 to 5/10/21 Mileage 36510: Ford Service kept the vehicle for 7 days but were not able to duplicate the failure and, therefore, not able to find the cause of the parasitic drain on the battery. They checked the alternator, the battery and the amp draw (50 ma) on the battery. All were okay. Ford Service indicated they cannot find the cause of the drain unless the vehicle is in a failure mode. They suggested having the vehicle towed in when it fails and without (jump) restarting it. I am not real positive that they can even find it then but that may be my only option. The Ford Service Rep did not think it was the Body Control Module. I believe that Ford Service has made a good faith effort to find the cause of the battery drain. This intermittent type failure is not easy to diagnose. I am pretty confident that no lights or accessories have been left on or doors open which could have contributed to the failures. I can see one battery being defective but not three.
