Size H3 starting battery replacements?

[tls]

This is a picture of the internals of an Ohmmu 12V battery. Ugh. I would consider Ohmmu a "name brand" in this space but if you're thinking of others, I'd love to hear about them.

Never heard of that brand. I use Ecoworthy exclusively in both my home solar system 51.2V, and in my road service van to run the 12v air compressor. DC House is another good brand (owned by Ecoworthy), WattCycle is another good brand, those are the few I know right off the top of my head.

I am happy to be corrected. But not happy to learn my model has NCM.

Why not happy? The LFP will get some more longevity, but it has lower energy density and performance. I would have been upset if I got the LFP battery...

Same! Also LFP is more sensitive to the cold!

Just a preference. Longevity, durability in charging, greater charge cycles, safer regarding thermal runaway and the absence of cobalt. I don’t live in a very cold place so that advantage of NCM is irrelevant to me. It also means more attention/care consideration toward charging applies. Don’t get me wrong, I am not going to rush out and trade it in.

You may want to clarify your statement. The Lightning HVB is not NCM as you have stated. They are LFP.

SOME Lightning batteries are LFP, but most, at this time, are NCM

Check your research. Only certain models get them and the Lightning only gets it in the standard range battery beginning in 2024, the Mach E gets it as well. The extended range batteries in the Lightning are still NMC

There is NO Lightning (2022-2025) with a LFP HVB. It was mentioned in the 2024 Order Guide as late availability but never materialized. All Lightning HVB modules use Li-ion pouch cells.

You may be confusing this with Mach-E's. Some newer, lower trims have LFP.

As I said - it never materialized on the Lightning. But did on the Mach-e. They may have tested it but it never went into production. FYI, the engine code (8th character of the VIN) would be "S". You won't find any production vehicle with an "S".

The Lightning LFP battery factory is still under construction.

They mentioned in the article that's one of the reasons they are building that new battery plant to supply its own LFP batteries as they currently have to purchase the cells thru CATL, a Chinese company.

Again - those LFP are going to the Mach-E, not the Lightning. The page you link clearly states the Lightning does not use LFP but uses NCM chemistry (in the form of Li-ion pouch cells). This fact is also in the 2022, 2023, 2024, and 2025 service manuals.

I see that now.

It’s so cool how a thread about 12V battery replacement devolved into an HVB chemistry debate!

I read a post here recently about someone ordering a motorcraft battery from RockAuto.com and it being less than the $215 you quoted. I'll try to find the post.

Yes! RockAuto has the Ford battery for $85.79 plus a $18 core charge plus $11.99 ground shipping. Seems like the best price going by far. Thank you!

The direct link to the product page is https://www.rockauto.com/en/moreinfo.php?pk=15222013&cc=3446918&pt=2476&jsn=8 but note it displays strangely on mobile, at least for me - searching for "BAGMH3" in the search box on the main page of rockauto.com let me buy it easily on my Android phone.

Check costco. I think they should be around $110-130.

Does the Lightning need to be programmed to tell it you put in a new 12V? I know on some cars it's recommended since it optimizes charging based on age degradation.

I said "need" to be programmed, I know it likely doesn't really matter. Just wondering if the truck has the capability of being told it has a new LVB.
