Any real solution for the "Charging System Service Soon" message?

Love it.
Using the Powerboost as an onboard 12V battery charger.

The truck has a fair amount of utility available. I have powered the RV many times. Charged the EV (Mach-E) once. This morning I used it to run a 120V air compressor to air up a tire on a car. And I've used it as a mobile office for countless hours.

Mobile Office mode IS a 12V battery charge session simultaneously.

And no error message when I left work a bit ago. If it's gone in the morning, the BMS reset fixed my issue.

Additional more key cycles and have not seen error come back ?

Well, for me it was swapping out for a Duralast Platinum H7 AGM battery and doing a BMS reset. No issues since. The truck should NOT have that much parasitic draw.

Hey so my dealer is saying the same thing if they change the battery to another oem would that fix it like it did for you or would I need to go to another brand? I plan on just a bms reset as well thank you in advance

2 months in, after doing the BMS reset and ALL battery issues are gone and have stayed gone.

Charged the batt directly to the posts until charger said float. Immediately did the BMS reset. Its important that on this one time, to charge directly to the posts, not the BMS.

Like magic.

https://www.f150gen14.com/forum/threads/no-more-battery-problems.24011/so do you need to charge the battery first before resetting the bms?

Edit. I misread. Thought you said change, not charge.

Yes, I charged the battery.

Just as I wrote and nothing more.

No worries Thank you

I ended up going with a slightly better battery, but can't hurt to try a free OEM battery if they're buyin

I had the same problem on my 2021 F-150 Powerboost XLT. Took it to the dealer. They applied the procedure in TSB 24-2442 and so far I haven't seen the message again. Cost me $225 in labor, since it's past the 3 year warranty period. Here's the entire text of the tech's notes on my service invoice:

INSPECTED VEHICLE, MESSAGE ON DASH DID NOT APPEAR, UNABLE TO DUPLICATE. CHECKED FOR DTC CODES USING FDRS, FOUND DTC B11D9-BCM FOR BATTERY VOLTAGE. CHECKED OASIS FOR FSA, TSB AND SSM'S, FOUND TSB 24-2442. TSB APPLIES TO VEHICLE. PERFORMED TSB 0.40 PERFORMED TSB 24-2442, CHECKED BATTERY STATE OF HEALTH USING BATTERY CHARGER/TESTER, BATTERY PASSED. PERFORMED BCM UPDATE USING FDRS, FOLLOWED ON SCREEN INSTRUCTIONS. AFTER UPDATE, PERFORMED BMS RESET, CLEARED DTC CODES. VEHICLE OK AT THIS TIME.

(not yelling, that's just how they write on the invoice. lol)

Hope this helps someone.
