How to charge properly.

[Kanuck]

Mine will show steady green until I "WAKE UP" the truck and then go to 1 red light. I can just come home, park the truck and plug in the Noco and it shows 1 red. The battery should be fully charged. I figure it is the logic in the charger that is doing it. Slow starting charge until the charger figures out where the battery charge is.

Cool, thanks for the info!

Like @Kanuck, I have also been using the NOCO, and when I check my SOC I have consistently been above 80% - 85% before I go to bed with the hood latched but not closed.

I have a NOCO on my wife's 2024 Escape (both on the fuse box using velcro), and both negative cords are connected to the body ground bolts.

Like others, if you wake the vehicle up for any reason, it returns to one red light.

Interestingly enough, when I went to lunch today, I noticed the battery gauge in the truck was reading 12V while driving. I stopped and shut the truck off awhile, and when I restarted it, I got the "Ford F-150 Saved" message again. When I started driving it took awhile for the gauge in the truck to go back up to 13.0 or 14.0 volts, and when the auto-stop/start action happened and the truck restarted, I saw that gauge dip down into the 10.0 - 11.0 range at times.

I wonder if I have a bad battery?

Keep in mind the BMS and other computers will control the alternator to output only what the computers think it needs to output so as to (supposedly) prolong battery life and save a few drops of fuel by not driving the full output of the alternator all the time. Also that readout you are looking at will only show whole numbers (12.0 or 13.0 or 14.0), so the rounding error and the above varying alternator output make it nearly worthless to look at. That said I never have seen 10 or 11.

not sure on this one…but the “F150 saved message” I think is just the APIM (Sync) message booting up into the saved configuration that you used on the screens last time. It is not the “shutting off system to save battery” message that everyone with battery problems talk about.

You know you may be right about the f150 saved message. Though in the past it seems to have gone away when the truck was driven for a more prolonged period, and likely a higher state of charge on the battery. I guess I just keyed in on it, when it started showing up after the truck sat for a week, along with the older chime sound which is indicative of a low battery. But I agree those things are probably independent of each other.
