battery deep sleep mode resurfaced

[stlgrym3]

My 2023 powerboost was having deep sleep mode issue since i took delivery last February. Finally 8 months ago, dealer replaced the battery, and it's been fine up until last week when the battery save mode resurfaced. funny thing is i have been driving the truck way more now than 8 months ago, and the fact it's still going to deep sleep mode really doesn't make any sense. i took the truck in for dealer to check, and of course they said no error codes on the vehicle. i noticed there's this OTA update 6.50 that's keep failing every night during the install, maybe that drained the battery? or, could it be the other way round, the voltage in the battery was too low so it was not able to install the update?

I read about the truck needs to be driven at least 30 mins a few days a week for battery charge stays in optimum range, this weekend i took the truck for a trip (around 700 miles round trip), after i got home, i immediately manually push out the update via the "UPDATE NOW" button, it worked, the update finally got installed. but this morning the truck was in "semi" deep sleep mode again, meaning I don't see the warning on the app yet, but the proximity light feature and dome light upon entry were off when i got in the truck. i think it'll go into deep sleep mode for sure tomorrow.

here are my options:

1. keep bugging dealer for another battery replacement, but even that is like crapshoot, depending on which batch of batteries dealer gets the replacement from.

2. get a battery tender plug in every night, seems ridiculous for a 80k truck which i do drive everyday. (need some recommendations on the battery tender)

3. get a battery charger and Fordscan, whenever this issue happens, charge the battery and reset the BSM.

which route would you go? or are there any other solutions to this? thanks in advance.

There are very many threads about this. Truck really struggles with short trips and sitting. I can park at 5pm friday night with 12.65 volts and be in the mid to low 12.2's on monday morning if i don't touch it all weekend. Depending on the way the wind blows, it might not even charge on your 30m drive if all the conditions are not met.

A charger is prolly the way to go.

FWIW, My Dad's 2023 Tacoma cant take sitting either. He drives it maybe 30-45 min a week.Not enough. Its on a trickle charger now. This is going to be more and more common with newer vehicles.

Split for a non-Ford battery - I think that'll fix it.

Good morning. I can take a closer look at your deep sleep concerns. To get started, could you please send over a message with your VIN and estimated mileage?

I was having deep sleep mode issues with my ‘21 for months . I did a battery monitor reset and it hasn’t been a problem since I did it. Simple to do , turn key on flash the high beams 5 times and hit brake pedal 3 times and wait for battery indicator on dash to flash .

I can only speculate as to the reason why... But it appears to me that the Ford Batteries just have problems that seem to go away when a new and non-Ford battery is installed. In my case the "funny" readings began at about the 4 month point after delivery. Because I was on the road for Thanksgiving, and didn't want to risk getting stuck somewhere, I pulled into a nearby NAPA dealer and bought a catalog specified, off-the-shelf, new battery. I wasn't smart enough to do a battery monitor reset. Not a peep since out of the truck's electrical system through two Wyoming winters (EG as low as -40ºF and commonly -20ºF).

Makes me wonder, Can you reverse charge the battery thru the trailer connector? Obviously nothing huge, but a low amp trickle charger wouldn't be too much of a load..............

I had no stop related issues with my '21. Tired the charger/tender, tried changing the management in forscan, tired the headlight/break reset thing. None of it worked for me. I finally got a AMG battery from sam's, I haven't had any issues since then. The factory batteries are junk, imo.

I ened up getting the larger one for the diesel f150. I can grab the part number later if you want it. You just have to remove a spacer they put in there. The trays are the same size. Im not sure if its the same post refresh though

I know that I've posted it many times, and thus sound like a broken record.....

But in examples like this, it would at least remove the guesswork regarding the battery SOC, as well as a historical log to help understand the ups/downs of the battery 24/7

Install a cheap Bluetooth voltmeter. Use your smartphone to monitor and access the logs. You don't have to touch the truck. You only need to be within 30 feet of it to "sync", and then see the current SOC, as well as access the log data.

I'm still on my OEM Motorcraft battery in my 2022. (~900 days in service)
I used to have to nurse the battery with a battery charger/maintainer, but a few months ago Ford updated the charging strategy and now I only have to intervene if the truck has sat for a lengthy number of days. (It's a Powerboost, so I can either put it on a charger, or just start it and leave the key inside and walk away. The truck will use the DC-DC converter to charge the AGM for the 30 minutes that the truck will be on.

My 22 was having issues going into deep sleep mode , weird random faults like trailer brake controller , active air dam faults , wouldn't do OTAs unless left on a trickle charger etc. Luckly for me one of my buddies is the lead wrench at the ford garage and every time i would get a weird fault id text him a picture , he would log into my truck via his work computer never once did it show a fault on his end , he knew what it was instantly as the BMS wouldn't let the truck charge the battery over 50 percent state of charge , He reprogramed the BMS and bingo back to normal .

I got it on your strategy... But at the end of the day, the day I put in a non-Ford battery was the day I began doing nothing but run the truck when I needed the transportation. I later put in a separate voltmeter to keep track of things. Yes Ford does program the charging to bring the battery up to about 80% or about 12.9 VDC. I believe this is their design to prevent overcharging damage to AGM Batteries. On the other hand I now see cold weather voltages remaining around 14.9VDC even long after the engine compartment has to be fully warmed up. I don't think this is a good idea, but whether this is a good idea remains to be seen. Apparently the voltage temperature compensating circuit sensor is located outside in the Pax side mirror thus explaining the lack of responsiveness to engine compartment temperatures. So what's up with Ford Batteries? No idea, my initial take was trucks left out "in the field" awaiting parts. That's behind us now, so I conclude that the contractor supplying their batteries is using a faulty mix in their alloying process.

Has anyone tried the 12v lithium "starter" batteries in the powerboost? Mine is about 2 years old and has started having issues with sleep mode.
(Do not post info on lithium vs lead; I'm well aware of charge curve and voltage differences, these are allegedly managed by the "starter batteries" BMS.)
I've search the forums and don't see any threads but I'm sure how good the search function is.

so two things to point out. A lithium battery will not charge properly with the truck. A Powerboost does not have a “lead” battery. It has a AGM so you might want to adjust your line of thinking to the proper battery.
