To be clear, not everyone is suggesting that; there's just a little bit of ... fanaticism on the subject that surfaces here regularly. And it's a mischaracterization to call Subaru batteries "crappy" -- they're just typical OEM batteries.

Subaru is very unlikely to help you pay for a third-party battery. I would accept the free replacement from Subaru with the knowledge that if you don't mistreat it, it will serve you well. A few years down the road, you can decide how much you want to spend for your next battery, but with a free battery in the offing now, you might as well hold onto your money till then.
Yeah, I agree. That is my plan, to have them replace it until my warranty covers it. When it runs out, I'll buy a better one. I honestly don't mind if it takes a bit longer, it's their reluctance or inability to give me an ETA that is bothering me a lot. Next plan is to call SOA to see if they can figure out if other dealers nearby have the battery in question in stock and if not to at least get me a loaner for the time being. Regardless, this forum is proving to be very informational and helpful. Like I said before, I have almost zero experience with cars, but I am learning a lot here, particularly about OEM batteries and AGM batteries and such. I am gonna read up a bit more on this stuff to get myself familiar with other related terminology.

I don't think it's so much that Subaru provided crappy batteries. They are just a bit undersized as far as CCA.
The stock Crosstrek battery has a Group 35 with 550 CCA.
I replace mine with a Group 35 with 640 CCA, better battery for our colder climate.
A quick google search revealed that the CCA metric helps with the colder climate like you said. This car has never been outside of Texas, so I am not sure temperature's the culprit here, especially the last few weeks when it's been in the higher 70s.

The problem we had with the 1yo Panasonic OEM battery was in the mountains when it had been 13F overnight. To me, it's worth a few bucks to get a battery that can cope with that. After all, that's one of the reasons we got a Subaru!

@AstroKats I want to preface this that I'm not being snarky, just genuinely curious. I've read so many times about your ordeal with the battery in the mountains almost not starting, and also have repeatedly read that you don't have a long daily drive with the Crosstrek living in LA and working from home. So I'm curious if you ever put a maintenance charge on it leading up to your mountain scare. Could it have been in poor health from not much use? I'm not doubting that the OEM isn't the best battery, or that you could have had a bunk from the factory unit. I've had mine about a year now with many nights this winter between 0-20's F and it's done well so far. I do top off the charge now and then tho.

No snarkiness taken, LOL!

No maintenance charge which, btw, is tricky for the millions of us who live in condos or apartments. I would expect a battery in a brand new car to last more than a year, even if not fully charged by short commutes in traffic and grocery shopping runs. Again, this is typical for millions of people who can't trickle charge their cars. I've had many other cars before and since without this problem, with the same usage (my L-car has has been driven even less). I've acknowledged that the OEM battery may have been a random dud, or that it was abused before we took delivery of a brand new car. Not sure what else to report. Since we were regularly going up into the mountains with sub-zero temps I thought it was worth investing in a high-end battery, much as one would buy chains, etc. I haven't taken the L-car into the mountains yet due to the ground clearance and approach/departure angle, LOL.

Heat kills batteries. After the heat weakens it, it will not start in the cold.

I have a '21 Limited and the OEM battery: CCA = 620A. Still have the original battery in New England BTW - I disabled the auto Stop/Start feature. I wonder how much effect that feature has on the battery's life span.

They upgraded a lot of features to handle stop/start. Maybe the battery, too.

My 2019 and my 2020 had/have Group 35 550 CCA batteries from the factory. The 2019 has been replaced, the 2020 is chugging along just fine on the OEM battery since birth.

My 2021 is out on "maneuvers" this week so I can't check it.
Maybe Subaru wised up and decided to stop using under powered batteries.

Have you considered a solar panel charger? (didn't you mention you had?) Plugs into the OBD-II port. Cable has a short piggy tail such that the panel can be unplugged without taking the OBD-II connector off and on.

Solar charging doesn't work so well in an underground garage. You're right that I tried a solar panel in the moon roof but that didn't work either, too much tint.
