Hybrid 12V Battery Charging

[NedF]

Apparently it's a Ford/FordPass feature: 14 days w/o manually starting.

Vehicle inactivity for 14 consecutive days
The battery voltage drops below 9.5 volts
Extremely cold/hot weather conditions

Good to know, I will fire it up once a week until I figure out what’s happening with it.

I am not allowed to drive at the moment, and whether I ever can drive again is currently in flux at the moment.

Hope there's a positive resolution to your situation which is preventing you from driving.

As I am still not allowed to drive (I had a stroke that took away some of my vision - some or all of it may return, but only time will tell). As I mentioned before My truck sat for a week and did not go into deep sleep with the newish AGM battery installed. I put the truck on a battery maintainer, and it is interesting seeing how the charger reacted (You can see I fired up the truck once to bring it back from the 14 day deep sleep timer). The time between charge cycles is closing and the time it runs reduced to flatten out the averages.
