22volt battery issues just get the AGM battery

[Smendelsohn]

I spent a year reading about the 12 volt battery drain issues as I have the low battery charge state issue every time the weather turns cold. I finally went to Walmart and bought their 12 volt Everstart AGM battery did a battery replacement in the parking lot and have never had a problem since. Also Consumer Reports gives a High rating that specific battery. I wish I had decided long ago to spend the $189
(My take is that Ford in their effort to optimize MPG does not place an adequate battery or overly fine tunes the charging and perhaps is ducking what could be a very expensive mass recall of batteries.)

[RR - All the way]

May want to edit the thread title to 12 rather than 22???

My '22 hybrid battery's still kicking, had to put a charger on it twice last winter so we'll see when the first time comes this winter

That's the battery I'm going with when the time comes.​

"never had a problem since" - I can't really pick a time line out of that story.

2 weeks ago ... less than a year ago ... almost 2 years ago?

That brand has gotten good reviews over many many years.

So 2 weeks may prove you didn't get a dud that gets replaced under warranty (another nice reason for Walmart).
Less than a year - no big whup yet, give it more time.
Almost 2 years - that's good to know.

I can't imagine how drained a 22volt battery would be in this truck!

The more expensive AGM battery is more resistant to sulfation damage, but it will still occur eventually. Since the real problem is incorrect BMS software, an AGM only delays the issue until Ford does not have to pay for a warranty battery. Its a warranty cost reduction, that's all. The corrected BMS software is now 2 years late for delivery...

Just checking as I will eventually replace my lead battery BUT will TRY to get Ford to replace mine one more time,. Maybe even get an AGM next time will see.

BUT this is the battery you got right?

For normal battery charging issues, I would suggest that re-training of the Mavericks battery charging system is necessary (BMS). A Chronically under-charged 12 volt battery is a symptom.

It has been well discussed on other threads, but I thought I would mention it here again.

If the 12v battery is being under-charged, changing the battery is only a short term fix...eventually the new battery will also fail.

The page indicated below will get you in the ballpark in your manual, but I will clarify a few things I have learned here and do myself.

I still have my original AGM battery (truck purchased 25 January, 2025). Read the manual on how to do it.

My notes in addition to manuals instructions learned here on MTC as well as experience.

- Manual says 8 hrs of sleep...make that 10 hours to allow all the modules/electrical background stuff to shut down before the 8 hr clock actually begins...it takes about 75 minutes after you lock the truck for everything electrical to shut down.


- Now...before doing anything use an appropriate smart battery charger (Flooded Lead Acid or Absorbed Glass Mat, new ones do both) of at least 4 or 5 amps to fully charge the battery as it must be a fully charged battery so the BMS learns what a properly charged battery looks like.

-Once satisfied the battery is at optimal charge condition, set the park brake, ensure ALL ELECTRICAL LOADS ARE REMOVED.

' Disconnect everything you have added that plugs in, GPS, dash cam, flashlight etc. This should be done before beginning charging the battery now that I think about it.

- Remove the charger, close and lock the truck up, all doors, windows, tailgate, rear window...everything closed and locked

Take your keys and store them far away from the truck so no inadvertent pushing of fob buttons occurs.

- Do not open the truck doors etc as you will need to start over with the recharge and relearn cycle.

- DO NOT USE YOUR FORD APP while doing your charging and BMS re-learn!

- Opening and refreshing your app will awaken your truck and again you would need to restart the charge cycle and then the re-learn cycle as well.

- Again, if you are having other problems with your system - parasitic draw, whatever...this will not fix that. This is only to train your truck to charge your 12 volt battery properly.

- I also hook my battery up every month or two and do several recharge cycles, to make sure the battery is kept in the best condition possible.

- If you have changed your battery, there is info in the manual in the area of the page. If you haven't read it, it is on your best interest to have a look...we can't just throw any new battery that fits in, anymore.

Cheers

Andy
