Thanks for the offer to check @rugedraw . My VIN is 1FTEW1EP7NFB83076

 

OTA trigger was created on 1/10 and is good for 30 days, so you have until 2/9 to get it to go through. It is failing due to very poor battery conditions.

Battery capacity if you have the OEM battery should be at 70 and yours is at 18. SoC is at 53 out of 100. I would recommend fully charging the battery, reset the BMS and then try the update again. If you have a good charger (20amps +), I would leave the charger on the truck while you attempt the install.

 

Interesting. Thank-you for that. I've never had issues with the truck/battery. Would you say this needs a trip to the dealer for them to test the battery?

 

Man, what a resource you are! Ever consider changing your ID to "SaintRuge"?

 

The dealer would have to perform a Rotunda battery test that takes 2-3 hours to do. If it fails that test, they will replace under warranty. If it does not fail, they can't bill Ford for the new battery. I would try charging it up first before going that route.
lol I have not, but it does have a nice ring to it.

 

With all the issues owners have been having with their batteries from Ford, if charging doesn't get you there, I'd take it as a sign and just go to an automotive store and replace that Motorcraft battery that came with the truck with a good AGM battery.

Does anyone have a recommendation for a battery charger for our trucks?

 

This one was recommended on another forum because it can double as a power supply to hold the battery up during long OTA updates:

Clore Automotive PL2320 20-Amp Fully-Automatic Smart Charger, 6V and 12V Battery Charger, Battery Maintainer, and Stable Power Supply with Temperature Compensation https://a.co/d/itHMwYU

 

The charger that @RossRR mentioned above is great. That's the one I have and it is still on sale for $80 from $180.

 

NOCO GENIUS5, 5A Smart Car Battery Charger.

I got this one a year ago when I first got my truck, and I could not be happier.

I got the extension cable (below) and ran it through the grill, (the charger is directly wired to the battery) and I can be charging in 30 seconds without opening the hood, (truck is parked in garage). The pigtail end to the cable tucks perfectly into the hollow space on the back side of the grill and is not visible when not in use.
