I guess in my mind I just shouldn’t have to use a tender once a week or so. I’m just wondering if my battery is just shot and not going to ever return and maintain full capacity. I don’t mind ASS either. And I’m not trying to get my battery up necessarily to get that function running, I just want my battery to be stable and not leave me stranded in the near future. I’ve just been using the lack of ASS as an objective measure as to whether my battery is healthy or not. I do know battery isn’t the only condition when deciding whether that system activates or not but certainly a big component of it.

The "Space GhoST" has lost its powers....

I think you need to do a little test. Drive somewhere at freeway speeds for at least 30 minutes and then back home. Then test the battery. I am going to venture that the battery will be back to 12.8. Short trips (10 minutes) slowly drain the battery, as the short run is not sufficient to replace the power used to start the vehicle. And there seems to be a pretty good phantom load when the vehicle is off. Good luck.

Because all of these control modules are voltage sensitive, my experience is the ST has to have a good charged up battery or you'll see all kinds of errors. Probably 2 1/2- 3 years is maximum. On the bright side $200 for a new battery every three years isn't all that bad.

well there's always going to be a drop. the car doesn't charge the battery to 100%. On a good battery, it'll stop charging when the battery target is reached and the alternator won't be active. I have always used my radar detector in voltage mode to see the changes in real time. I knew my battery was on the way out when the alternator was always on, which for me is around 14.6-14.8V and with the car off, voltages went from 12.3-12.4 to 11.9-12.1.
I took my ST in to the dealer yesterday with 35,200 miles on it because for the last week or two the vehicle goes into deep sleep mode, within a few hours, every time I turn it off. I told the service advisor that it was going into deep sleep mode and the response I get is "what the hell is deep sleep mode?" (He wasn't being shitty, I think he was genuinely confused or likely had never heard of it). So I showed him the app and he asked if I spoke with the Ford Pass people to make sure it wasn't an issue with my phone 
I told him that never happens with my 22 F-150 and that those same errors I get on the Ford Pass app should show up in PTS or OASIS, I cannot remember which.
Anyways, It did it again overnight while the vehicle was sitting at the dealer and hopefully they can just replace the battery under warranty. But I'm sure I'll get the "it tested fine so there's nothing we can do". This dealer I took it to isn't all that great, but the good dealer in town is about 40 mins from my house and this one is 5 mins from my house, so I figured I'd give it a shot.

This is a voltmeter that will plug into a car 12 volt outlet. They are commonly available on the Internet. I leave it plugged into the outlet at the front of the console under the lid. It is easily readable while driving when the lid is opened. If I have just been doing short trips it will show 14.7 volts while driving, bu if I drive on a longer trip it will reduce to 12.9 volts. This shows that occasional longer trips are required to keep the battery properly charged. BTW the power to the outlet is automatically removed a few minutes after the car is turned off.
This is one example:

Well after being in service today my battery tested good. What they did find was DTC U0102 stored in the ABS module. They reprogrammed the ABS module per SSM 49045. https://ford.oemdtc.com/7190/awd-va...er-police-interceptor-utility-lincoln-aviator Also has the backup camera recall done while there. On a side note had an oil change while there. When checking the cabin air filter it looks like a mouse chewed a hole in it. Didn't appear to be any other damage from it. Plan to order that voltage meter Kansas posted. Looks like any easy way to keep an eye it. Thanks for the suggestion.
