Ford pass saying battery saver mode

[HeyBales]

Should I disconnect the battery during charging after making the changes.Then reconnect and do the double lock and sit for 8? If not connect the charger at the battery or under the hood at the jump posts while leaving it connected.

I have to tell you, that if you own a Ford you must have Forscan. It gives you the ability to change and or fix and correct many functions. This is my second Ford. Last one was 40 years ago. I am again disappointed and this will be the last. Quality?

So to be clear - you are a test case, if you don't mind that.
As I mentioned - everyone else I've seen that posted making this Forscan change seems to have also swapped battery to AGM and/or removed fuse for modem - at the same time.
So hardly a proper experiment showing it was just this variable that gave the success they saw.

Because for awhile now - it seems to be known this setting is not actually for the hybrid.

Adjust Battery Target State of Charge (Ecoboost only)	BCM	(EZ) Change "Battery Target State of Charge" to desired value (% percent)				Factory = 80% , suggested change 95% (RESET BMS AFTER)

While you are getting into Forscan - you can search for other PIDs like Auto start stop and find settings that obviously don't apply to the hybrid - but they are there. And even some settings regarding a 2nd 12V battery - which obviously don't apply to the Maverick at all.
So all kinds of orphaned settings and PID readings that don't apply.
Like those I mentioned regarding the battery stats - the manual says for the EB version that stats should be changed if different battery is used. So those are likely for the EB only.

Charging can be on the posts, disconnected doesn't matter unless your charger says it'll do something special if not in-vehicle (like high voltage zaps for extra de-sulf has been claimed).
Truck only logs Amp hours charged when key is on - otherwise it uses the BMS Relearn to discern full charged battery. You can do the BS Reset routine too - but that did nothing for mine except Zero those PID values I gave above, I'd skip it since still the age in days is useful.
So yes to remove charger before you lock for 9-10 hrs.
(I say more than 8, because manual says 8 hrs in sleep mode - which occurs max 75 min after door closes/locks)
You are in a 24MY like me - I've not see the double-lock change anything on ours for lights, I think we got a software change already. Didn't help much frankly.

I actually do the reset every night. Also my last battery was a higher CCA of 470 and seems to be holding up better. We will see, it's only been a few months.

You do this every night?
So every night, not matter what charge level it's actually at - you are telling the system you have a new battery?
That ain't right!

Battery Sensor Reset
When you install a new battery, reset the battery sensor by doing the following:

1. Switch the ignition on, and leave the engine off.

Note: Complete Steps 2 and 3 within 10 seconds.

1. Flash the high beam headlamps five times, ending with the high beams off.

1. Press and release the brake pedal three times.

The battery warning lamp flashes three times to confirm that the reset is successful.

Op,
I got my 2024 Ecoboost Lariat on 12/31/24.
At 10,700 miles now, it came with a Motorcraft AGM battery.
It sat two weeks untouched last winter due to ice with all the from the factory battery drains on.

Never saw a Low battery sleep mode or anything. To this day I have never seen it.

That tells me it’s fixable.

Did mine get an update others did not ?
Because I purchased it so late in the year ?
I don’t have a clue.
Is it because I got a better than most AGM ?
I have not a clue.

My BMS (Battery Management System)
Charges my AGM to peak of 12.7 vdc at shut down after a drive and an at rest voltage (after 6 hours of sitting) of 12.5 vdc.
I am watching it closely,
Will it get through this winter ?
Who the F knows.

Did you know that,
Because of the ridiculous drains on a car battery in these over engineered over censored modern vehicles Interstate battery and several others only offer a two year pro rated warranty?

If I get a year and a half I’ll be happy.
I figure I’ll get one under warranty.
And the next one, the one I buy with my money I’ll set up an on board 1.5-2.0 amp tender/conditioner. And I’ll buy the biggest capacity , biggest CCA that will fit.

And Fagetaboutit!

Thanks I'm just going to send it. If i wake up one day with a dead battery then I'll replace with my own battery, with the highest cca. For now it literally is giving me no problems starting. Just the stupid modem isn't working. I got mine in late September. I pulled the fuse trying to wake the modem, and while I now have access to options on my app they still don't do anything.

Disconnect the battery, peak charge overnight then after that reconnect it.

I think that’s what the crew in here is recommending as a next step.

Batteries are living shorter lives because they are remaining at a TOO LOW average state of charge.
It seems.

Ain't that the truth.

Well - vast majority of battery issues is the hybrid - the EB's generally don't have them, unless one had that defective FLA that was installed for a range of vehicles.

To the above issue - that sounds like a connection/account thing - truck can report up stats perhaps on park, app allows seeing?, but reaching back out to truck fails.

The 14 days comment I'm surprised by in earlier post, may not have reached exactly 14 days in hrs since that's the timer, because it should have gone into Deep Sleep to conserve battery.

Also - if you go for bigger battery - the manual says for EB the battery stats need to be changed to match - you'll need Forscan for that, or dealer. (that's a difference with hybrid - no such comment on pre-25MY's)

More cca does has nothing to do with the computer. My 24s were not part of the battery recall. That's why we have an agm. Literally everything works except fordpass. Auto start. Remote/remote start, Still do, if they didn't than i would be more concerned. It just Literally gives me an error when I try to go to Fordpass thru the infotainment

I guess I misunderstood and don't do that complete operation you described. I have been doing the double remote push when leaving overnight.

I'm not in Kansas, and don't click my heals. Lmao.

Ya - account problem then, or modem problem.

My point about the battery stands - you said when it comes to it you'd get a bigger one.
Therefore this applies. Just keep it in the back of your mind when you finally do it.

Sorry what i meant, I'll just get another h6 just with way better cold cranking amps. There honestly not that much room for a bigger battery in that spot. Sorry for the confusion.

Oh, when I said bigger - I meant in stats like CCA which you said.
If you read the manual footnote you'll notice that is what it's talking about.

The charging system doesn't really care what physical size battery you have.
CA, CCA, RC, AH - that's what matters.

To many opinions with no resolution. Probably because the pros don't have an answer, and so it's left to us users to guess or make up a solution.

It's obvious that either a bigger CCA flooded or an AGM will last longer than the original. It still doesn't solve the real problem of the parasitic voltage draw on the battery while sitting causing sulfation and eventually failure. Also the possible lack of Fully charging the battery to keep up. IT'S NOT necessarily a BATTERY ISSUE. Read the years of threads on just this forum.

HeyBales, thank you for all your insight and actual knowledge. To much misinformation going on.

Yes yes agreed

I have to wonder why the app doesn’t show the level of charge or the current voltage of the battery. I know that my windshield washer fluid level is good though. Valuable information.
