I still have my original batteries in my 21 PB with under 29,000 miles.

Nov 2021 PB.

Replaced both OEM under hood and under seat batteries Sept 2025, just shy of four years old.

Why did you replace yours?

Why did you replace yours?

Deep sleep warnings and low voltage warnings within a week of driving over a few months period earlier this year. No amount of noco charging, fan speed settings, nor BMS resets would resolve. After replacement, no issues in the last two months.

Hm. Okay.

My truck has 65K on it now and I'm getting little weird things at increasing rates. Like the other day, my sunroof buttons didn't work. Turned the truck off, waited, restarted and all good. Like things aren't booting correctly.

Still going with my 21 PB battery. Build was March 30th 2021 but sat for 4 months waiting for chips or something like that. Delivery was in August. Came with a 800 CCA battery and dealer test last month with oil change showed 760 CCA.

I had both original batteries until Oct 1st, 2025 on my '21 job one PB. Long story, but constant deep sleep mode, no OTA updates, etc. Always started, even after two weeks in the garage. Main original H7, 12v tested 13.5 volts with 80% SOC. Both the auxiliary battery under the seat and the main 12v were replaced approx Oct 1st, out of abundance of caution before long road trip. OTA updates instantly started rolling in and no more deep sleep. FWIW I'd bite the bullet and replace the main with an OEM H7. Dealer said H8 was not an "approved" size per Ford.

This thread is as encouraging, as it is curious.

I thought the battery issues were more or less universal, especially of the earlier issues.

No issues to date on my original battery, I'm at 78k miles on a Job 1 2021 Powerboost.

Sorry for beating the dead horse, but I've been watching the battery threads for a couple of years now and I've been using a BatteryMINDER Plus periodically to top off my battery. I also run my AC/Heater fan speed at 5 or higher on occasion. My truck is now fully 4 years old. It sits in the garage quite a bit and can go a couple weeks without being started. I checked the resting voltage this morning after sitting for 8 days without any supplemental charging. It reads 12.45V. This seems pretty good to me considering the age of the battery and other's experiences. I've never had any low battery warnings. I wonder if I'm the only one with an original battery and no history of trouble? Maybe 12.45 isn't that great?

Picked mine up in October of 21. 78k and original batteries

Not trying to be a jerk but your 2019 isn't a Gen14 F150 and doesn't really apply to the conversation here. Asking in earnest, why are you on these forums with a truck that doesn't even go here? It would be like posting about a Ranger here.
