Battery issues solved, finally!! Replaced battery with AGM

[MakinDoForNow]

After 3years of dealing with the issue re deep sleep, no auto stop, removal of ford pass and 3 trips to dealer I have solved my battery related problems (which dealer denied I had). No start 1 week ago, replaced battery with AGM and I have my truck back!! Every thing works as it should. And should have been fixed 3 years ago if dealer had put an AGM replacement that they told me wouldn’t help!! . I don’t trust dealers even more now. Even good mechanics have to follow the company word so it’s not their fault entirely but damn! Would it have hurt to take care of my problem 3 yrs ago?

still love my truck. Even more now!

Ok did some looking and found couple things:
#1: someone in F150 forum using forscan to set battery type to AGM. This was 2021 so maybe the codes then are not the same now and/or may have different ones for valid maverick. From what I've read the 01 is for a BC AGM and the code 02 is for AGM... etc.
#2: a link to different f150 thread has 86 posts from someone asking about installing different battery. Member bluegrass post quite a bit on the Ford BMS and in one past halfway if I remember correctly stated the different items (8+?) that the program used to charge the particular selected battery (variables different for different batteries, etc.).
Need to find the table for all Ford allowable battery types and their xx codes.

All depends on the dealer. I had my original battery replaced as defective by the dealer within the first 3 months I owned my truck.

No friggin way I'm paying for something that should and was covered under warranty. Way to cheap for that.

it’s on page page 314 of the manual for 2022 ecoboost

I don't see anywhere it's going to know it's an AGM.
I do see it says to do the same reset routine that's been mentioned.


The battery is in the engine compartment.See Under Hood Overview - 2.0L EcoBoost™.
Your vehicle has a maintenance-free battery. It does not require additional water during service.
If the vehicle battery has a cover and vent hose, make sure you correctly install it after cleaning or replacing the battery.
For longer, trouble-free operation, keep the top of the battery clean and dry and the battery cables tightly fastened to the battery terminals. If any corrosion is present on the battery or terminals, remove the cables from the terminals and clean with a wire brush. You can neutralize the acid with a solution of baking soda and water.
We recommend that you disconnect the negative battery cable terminal from the battery if you plan to store your vehicle for an extended period.
Note: If you only disconnect the negative battery cable terminal, make sure it is isolated or placed away from the battery terminal to avoid unintended connection or arcing.
If you replace the battery make sure it matches the electrical requirements of your vehicle.
If you disconnect or replace the battery and your vehicle has an automatic transmission, it must relearn its adaptive strategy. Because of this, the transmission may shift firmly when first driven. This is normal operation while the transmission fully updates its operation to optimum shift feel.

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.

Battery Management System (If Equipped)
The system monitors battery conditions and takes actions to extend battery life. If excessive battery drain is detected, the system temporarily disables some electrical systems to protect the battery.
Systems included are:

• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.

A message may appear in the information display to alert you that battery protection actions are active. This message is only for notification that an action is taking place, and not intended to indicate an electrical problem or that the battery requires replacement.
After battery replacement, or in some cases after charging the battery with an external charger, the battery management system requires eight hours of vehicle sleep time to relearn the battery state of charge. During this time, your vehicle must remain fully locked with the ignition switched off.
Note: Prior to relearning the battery state of charge, the battery management system may temporarily disable some electrical systems.

Your battery likely failed their load test, especially if you started having issues at 3 months.

When mine started going into deep sleep at 11 months, I took it to two different dealers.
They both said it passed their tests. When I asked why it kept going into deep sleep they had no answer, but still would not replace it under warranty.

Do you now have all of the WIFI connectivity activated?
I turned all of that off when I got mine, and have had zero issues for 11 months now.

I think mine just died this morning. I've been chronicling my issues all throughout this forum. A new battery is just kicking the can down the road.

 

[NJBob]

Didn't read it in the manual.

Because it's pretty doubtful we have the best system.

Sorry did not mean to say best. Was supposed to read bms.

Understand, others have been wrongly auto corrected by computer also.

It's the nature of the beast! Computerized. Plus relays, etc including non air gap switches which may not totally set h off and leak current. I regularly put mine on maintainer and have never had a no start. However one could kick the can further by Installing a second battery and relay to turn on a maintainer when ignition is turned off. Second battery with its own separate BMS would charge all the time if needed that ignition is on. The second battery most likely would double to quadruple the life of the perceived POS OEM 12v. Remember the truck never totally sleeps.

I agree. Yes, we all might be kicking the can down the road, but I don't want to be in the middle of a 200 mile drive, in the middle of the desert and have the truck die on me. I have an AGM battery. I carry a booster charge. I have not had my AGM battery die on me. The two flooded batteries (the original and one I replaced) died within 6 and 8 weeks after being installed. This tells me the system doesn't send enough charge for a flooded battery to maintain.

My next step is to buy one of those Forscan things and set my charge rate to 95%. I truly believe that once that is done, I won't have any sleep messages at all. To those who are still driving their Mavericks with the original batteries for 3 years and haven't had ANY issues......................happy for you!

I too put mine on about once a week. I haven’t swapped it yet but it’s not holding a charge as poor as it was before. Sadly it’s much worse.

Good luck to you also. In post #16 this thread I posted link to F150 forum discussing Ford's BMS. Control program for it selects vehicle it's in as well as battery installed. I suggest reading it paying attention to bluegrass members posts. He comments when BMS charges and doesn't charges and why. Here is screenshot of one post.

Please keep us updated.
Especially about how easy it was to use the Forscan when you get one.

When I put mine on (a Nico g5 multistage maintainer). I try to leave it on for several days maybe a week. Not necessarily continuous if I need to drive but back on ASAP. This allows the automatic optimization routines to run after battery is fully charged and replaces any drains ASAP. In order to keep battery topped off the maintainer needs to be at least 4amps (reported by someone here) to trickle battery and furnish current during the random charges. If you have OEM replaced keep the old one charge it and run a repair cycle one it then leave it on maintenance and swap with replacement when needed placing the removed one on repair/maintenance! Just a thought.

Here's some PID's with settings or values for Maverick that I'm thinking don't matter - IE value not used elsewhere if even stored. I'm thinking some of these likely came with code already written so they just kept them, and only use what they want. Or they forgot to access it.
But the module may store other info, much like the PCM logs seconds of engine idle time but not in a PID I can find.
2 of these do have values to display - Days in Service (or since last battery sensor reset in my pic, maybe not best to do that routine unless actually a new battery), and Battery Charge Mode - Standard.
I wonder if an algorithm uses that days of service...
Battery Capacity & CCA holds a value - but mine had no values so must not be used.
The check marks are in the middle of the options - not selecting an option - why I think it's not used on actual display of values.
