Recall: 25S02 12V BATTERY INSPECTION

[CurtisB]

My VIN# and build date isn't in this recall. But I am in the rear camera recall.

everyone advocating against a BMS reset is crazy. it has fixed deep sleep in many occasions and there's no downside in the method I mentioned (long drive after to fully charge).

The downside is (in case you missed it) the process "tells" the system this is what a healthy 100% charged battery looks like.

If you do this with a 50% charged battery, this is the new normal the vehicle's system expects. So it can be harmful, if improperly done.

You can unwittingly "lower the bar" so to speak.

Correct me if I'm wrong , but wouldn't sitting , in the run position ( hybrid ) charge the battery as well as a long drive ?
Weekly I pick up a granddaughter from school , 25 minutes early to assure a parking spot , and leave it in the run position . The ICE may start once or twice in that time .
My plug in voltmeter shows approximately 15 volts the whole time , the same voltage as driving .
And yes , the voltage reads less than 12volts when I monitor it , in the morning ...

And yes , FORD needs to speed up the fix !

My 2022 manual says that the relearn MAY have to be done AFTER RECHARGING or when new battery installation.

I'm wondering if they figure a majority will already meet the conditions required for it to happen on a regular basis anyway.

But just in case you have garaged the truck and don't lock the door, here's what you need to do.

Yes to all.

The batteries are most likely defective, not the truck. Or the batteries soon become defective because of the truck.

At 6 months old, my 12v would test "weak" with unlimited hours of charging.

this recall mentioned in the first post and title of this thread currently has a scope of only enhanced flooded batteries used on certain (early) ecoboost Maverick and Bronco Sport models.

every single reply I've posted in this thread is specific to ecoboost. this hasn't stopped GPSMan/TheRealMaverick, HayBales and plenty of others from chiming in about things that may or may not be relevant to hybrids, but they definitely are not relevant to ecoboost and this recall.

if you have an ecoboost that shows a deep sleep message, regardless of what battery you have, the best thing to do is reset the BMS, start the truck, disable autostop and go for a long drive then park it for 8 hours. why is this helpful? because the BMS may be set wrong from the factory and/or its self-learning has set bad values. will this help every ecoboost having deep sleep issues? no, but it's easy and free, so people should try it.

You are correct - driving doesn't change anything that I've ever recorded, compared to just sitting with HVB recharging.
The 15 V is fooling the figures though.

Actual charge rate starts at around 10 A charge to the battery for some seconds, down to 5-6 A for perhaps a minute, then drops 2-3 A for another min or minutes depending on where SOC is, then down to 1 A or below afterwards.

I had several short trips Fri night, with truck off for minutes at a time, and got the SOC up there better than I'd get with a straight drive home, and it was starting at 10 A with the quick drops each time. Compared to I've noticed sitting in driveway waiting, then a turn off, wait 30 seconds, and turn back on - does not fool the system, it went back to 1 A or less charging rate.

So you've got the following going on basically. Except the logic for how long each charge rate should last seems to be Ford's weird screwed up method. Those figures x 6 for cells.
This is what the EB system is attempting too.

At times I will put my truck into run (ready) position and let it sit. As monitored by some the 12v rate of charging drops to 2amp rate at about ,80% and shortly to 1 amp rate. Sitting in ready for about 1.5 hours will not fully charge battery but will get it to about 12.3-12.4 volts after about 1 hours of rest. Driving 9-10 hours with one gas, 3 potty/lunch stops will get 12.5 volts. Then depending on how long it's been since the battery has been treated for sulfation what percentage of the original reserve capacity remains available? There does appear to be problems with "the enhanced battery also" which Ford is intending to fix. Any 12v battery not fully charged will have a shorter life than one which is but may last longer than OEM due to primarily reserve capacity. Any battery I have in any brand of vehicle will have at least two 6-12 day visits on a multi phase maintainer.

I'm thankful I've never had the "deep sleep" issues some have had. My 2022 XL EcoBoost will go into a "light sleep" after three days of no driving (no interior lights when you open a door), and a "deep sleep" after 14 days (cellular connectivity shuts off). I'm sure there are other things that shut off in both of those modes, but those are the ones that come to mind.

I've had similar experiences with my 2023 EcoBoost.

I think those timeouts are the way it was designed. "Deep sleep" after 24 hours suggests something is broken.

My truck is sitting at the dealer for some warranty work and they have verified that the latest recall is not for a new battery. It will be an over the air software update for the truck once its released, per Ford.

I don't think the Maverick supports OTA updates outside of the WiFi updates to the infotainment. Hmm..

There are 2 Recalls. I think they are getting the battery recall confused with the backup camera recall.
