The electrical system is controlled by the BECM and the factory setting is at 70% ,at which the alternator clutch will stop sending voltage, into the battery, most likely to prevent overcharging or battery exploding.
Sounds good, right. But the Start stop system is disabled, Ford says at 75% or so. Ford says run your Bronco at least every 14 days.
Ford Pass keeps only the current battery voltage, but sometimes records alternator output like 14.9 v. You will not see it on Ford Pass, but girls can give you the actual voltage, except as stated before.
Took MY22 Bronco in Feb 2023 and asked to have AGM checked out. They charged for one hr. and said good. Readout 12.43 v or say 80%/ never got higher per Ford Pass. Why. Three stages in battery charging: bulk 80%1 hr; absorption +2-6 hrs; float 100% 4-6hrs. This prevent sulfide issues, which kills batteries!
Ford supervisor in CRC said her technical people said can't change factory 70% BECM computer setting, so if battery is not removed from Bronco you will never have a fully charged (13v) AGM.
If AGM under-charged, like 70% it will last 3 years even with a trickle charger. Why 70%! The owners manual cautions you where to attach the jumper cables. Red to red battery terminal but black to ground lug, not black terminal. WOW does the tow truck guy know that.
Today after 21/2 Hrs a supervisor CRC calls her tech guy and he gives statement " change 70% in BECM will void your warrantee" . Dealers get .2 hr warrantee or say $27 for a one hour BULK charge to 70% and my start stop is still disabled, in summer the a/c will also get disabled by the BECM and Ford will do nothing.. They say drive your car, get to 36,000 miles and " Sorry Charlie" or take your roof off! COOL?
To make matters worse, Ford Pass reset its "Deep Sleep" computer settings on AMG now to 9.5v. Dead!
If they can't get battery management software right , how are Ford EV with new EV factory under construction work. Planned obsolescence ! Nothing new to Ford. That is why I just ordered my second MY 23.5 DEFENDER 110. You heard me one for Florida and second for New York, so the MY 22 Base Bronco don't feel alone in the barn. Build "Ford Wild" if your battery works! Give it 36 months like the AGM labke says! Another $350.00 installed. So change the oil every year and AGM every third oil change!
