11.7 volts at rest, 2.0 Ecoboost, 235 miles

[LM42]

I purchased a Diehard battery and replaced it myself, why? Because I knew it would take days to get an appointment, then my truck would sit at the dealership for a week while 3 guys named Ernie making $17 an hour tried to troubleshoot the issue, then someone would slam their door into my fender leaving me a nice dent, and then a week later I would get my truck back (best case) with grease tracked in it with another questionable Motorcraft battery with unknown date code that came from who knows where (and may have come out of someone else’s Maverick with the same issue). Then if it failed again, I would have zero confidence in the repair or replacement battery.

It was far, far less painful to spend the $200 for a fresh date coded (non Motorcraft) replacement battery, know it was installed properly, then go from there if further troubleshooting was needed.

I’m now on day 24 of the new battery and my Hybrid appears to be fixed...

A couple of things. You have a hybrid and the OP has an ecoboost. It is possible if not likely that they are not the same concerns at the root. And now thanks to the sleuthing of another member we see that the OP has only accumulated 235 TOTAL miles in 2 months? Of course that is a contributor. If he had that mileage on a new luxury car with more tech it would have been dead 6 weeks ago. This is an owner responsibility issue. Not a manufacturing defect. Also, you have obviously been soured with previous dealer experience and that is too bad. But all of the conjecture you posted above is just that. It is fantast until it is real. I am glad you have the funds and the patience to just put a battery in it yourself and move on. But, I would be lying if I said I did not LOL at your remark about buying a Diehard battery and that someone being automatically more reliable than an OEM battery. And the mere idea that your truck would end up with someone else's battery in it. THIS is why these forums are so hard to take seriously. The likelihood of that happening are at near zero. Like as close to zero probability as you can get. Yet you post it with confidence.

You know what else makes it very difficult for people looking for helpful information? Hecklers talking about word salads and complaining about complaints. Some of you who do this look like sycophant fanbois

In this context I am not sure you know what a "sycophant" or a fanbois is

"A couple of things":

I never responded to the OPs concern, I don't care about hybrid vs EB, my response was only to your post above: "I am baffled by posts like this. Why would you have to fix it or figure it out yourself? Pickup the phone, call a Ford service department and get it in".

I haven't been soured by anything, stop making things up. Mine is over 50 years of experience, and if you re-read, most of my service experiences have been positive, but in this case I would rather assume the responsibility and cost to attempt the repair myself.. .

I posted zero conjecture, I posted that I would rather spend $200 and know the battery is replaced correctly, than invest a ~week of my time and hope the troubleshooting and subsequent replacement was done correctly. No delays, no subsequent damage, etc. The cost doesn't move my needle, the time sink does.....

Do you know with 100% certainty I couldn't get another bad Motorcraft battery or do you know exactly where the replacement would come from or its date code? No, you do not

Can you guarantee the replacement battery's date code wasn't similar to mine? No, you cannot

I wanted "Motorcraft battery" out of my failure equation and I took the steps to provide the remedy..

Your comment "If he had that mileage on a new luxury car with more tech it would have been dead 6 weeks ago. This is an owner responsibility issue. Not a manufacturing defect"... is 100% conjecture and not based on fact. Again you continue to make things up as you go..... You have zero idea what the OP's root issue is, but want to latch on to Fossil's keen mileage observation and make it your own.... and then extend it to 'luxury cars'. LOL, please define 'luxury cars'.

And, oh, in your post #6, your comment: "many of you live in small towns. And with that comes a lack of talent" Pure ignorance......

This is all made up bullshit for something that "might" happen. Based on no real evidence. Just a couple of bad experiences over your 50 year history. Of course I would not know with 100% certainty that another Motorcraft battery would not have the same issue, and neither do you with regards to the Diehard, or literally any other brand you would buy, no matter the cost. And yes, a new replacement Motorcraft battery does in fact come with a date code. In case you don't know (I would not expect you to) I am a service advisor for a foreign luxury brand. I see this stuff on a daily basis. Many new luxury cars state directly in the manual now that the car needs to be driven regularly and cannot be left to sit and expect the battery integrity to remain. This is not made up, I do this for a living and get paid will to do so.

The OP has driven ~200 miles in 2 months. I can tell you it is factual that this is not only not enough to maintain his battery, but he has likely driven multiple short distance trips that would deplete the battery even further than just sitting.

So if you are going to pick a fight on here, make sure it is with someone who does not know what they are talking about. I am not that guy.

fun fact, neither Motorcraft nor Diehard make their own batteries. Johnson Controls is the primary maker of Motorcraft and some Diehard batteries. Clarios LLC makes the remainder of the Sears/ now Advance Autos Diehards. Motorcraft is made in the USA and Mexico. Clarios - USA
I had to replace two Motorcraft batteries in the past 18 months. Both were original equipment on my 2010 Raptor and 2011 E450 motorhome. I guess the E450 battery was defective as it failed before the older Raptor.

You certainly got your $$ out of yours...LOL Yep, there are surprisingly few battery manufacturers these days.... I've had what appears to be an infant mortality issue with a few of my Motorcraft batteries in the last 15 years. . My 2016 Platinum Expedition battery failed in 6 months. My wife's 2017 Platinum Explorer's died in about the same time, now my Maverick's.... My other 3 Expeditions, my 2019 Raptor, etc. had zero issues. It's seems like if mine made it by ~6 months they were good to go for years. I still have an original (not repro) Autolite battery for my 1968 1/2 CJ Mustang and '70 BOSS 2 car that still works fine, but it spends 363 days a year on the shelf and I run a Repro Autolite AGM's normally.

My Maverick's Motorcraft was manufactured in Spain.... I've searched all sides and have yet to see anything that looks like a date code,.

Once a battery OCV has dropped below 10 volts it is considered dead and will not recover to it's full capacity with 'normal' charging (some specialist chargers claim that they can recover a 'dead' battery).
Your OEM battery may have gone dead during shipping - doors left agar, transmissions left in drive etc. or on the dealer's lot then got a quick charge and delivered to the unsuspecting customer who then has problems with it 'down the road'.

You probably miss read my post. Both batteries lasted longer than usually expected.

I did have a marginal battery delivered in a Ranger, would go dead after sitting over three days. Took it in twice and it passed their test. After that I called them to tow it, it only took one time to get a replacement.
