These AGM batteries are pricey but great. I put one in my V6 Camry and it’s 5 years later and cranks like a demon even at 5 below zero.
Can’t find a battery replacement

Seems as though this one fits our CX-30 (if it fits a 2021 then it should also for 2022 version). I was thinking about upgrading my factory battery at the 24 month mark.

That’s a good one and it is the correct size. I think the Autozone model has 680 cca as opposed to 650. Not a huge difference but every amp counts!Seems as though this one fits our CX-30 (if it fits a 2021 then it should also for 2022 version).

Mazda and batteries are an old story... I had many Mazda3s, higher trims - 2004 GT, 2009 Mazdaspeed, 2012 GT and 2015 GT. All of them needed at least one battery replacement and I live down south where temperatures rarely get below 40F. It is something that if you love Mazda you have to learn to live with. Other than that I love my Mazda's. Now in process of buying a 3 Turbo Premium Plus knowing that this will happen again.
Seem like a common problem with all automakers & newer cars these days. Barely adequate (cost cutting) factory batteries provided for newer "tech-bloated" vehicles that sport more passive/parasitic draw than ever. My new-gen TNGA 2020 Corolla SE had all sorts of OEM battery failure problems (3 new batteries in 2 years). My older-school tech (but better vehicle) 2015 Yaris SE Toyota was still using its original factory battery 4+ years into ownership without issue.
Battery. I put mine on a charger and it 12.47 volts when charged, then it dissipates overnight to 9.5 volts or so. It was never that strong to begin with, it always felt a bit sluggish in turning over the engine.
So the dealer wouldn’t talk upgrades or credits, but they did warranty the battery, as it had, as it turns out, a defective cell. So I’ve got a new OEM battery with the same 550 CCA and conventional lead acid technology. I will live with it for the warm months, but in the fall it will become a backup battery and I will just buy a new AGM 680 CCA. Issue resolved, back to just driving and enjoying my hot CX30!
