Got an oil change the other day and they noted that the battery seemed to be running a bit less than ideal. I live in Minnesota so it gets really cold and believe it or not really hot too. My question to you fine folks, what is a good replacement battery for a 2021 CX-9 Signature? I am not going to do a 1K lithium crazy crap I have seen out there but thinking up to $300USD is reasonable for a good battery.
Good replacement battery for the 2021 CX-9?

I think these are pretty good: Advance Auto Parts - Down for Maintenance
If you are a member at Sams Club they have good deals on batteries and an AGM battery may hold up better than regular flooded lead acid in your case.

I've had good luck with the Costco Group 35 batteries, but that's mainly because their warranty here in Canada is still really good. I've currently got an Energizer Group 24F AGM battery from Costco in the car (they didn't have Group 35 AGM batteries in stock), it's been working just fine for me here in central Canada. Doesn't fit perfectly, but it's very close.
In your case, I'd probably go with a battery from Walmart. I'm not familiar with their prices, but their battery warranty may be better than Costco.

I'm also from MN, so I know what you're dealing with regarding temps.
Honestly, these days it's a crap shoot for how long batteries last.
I've purchased batteries from multiple places in the past.
Throw out Fleet Farm as an option as well.
2014 Explorer - Original lasted a little over 5 years. That battery just flat out died one day (good in morning, nothing in afternoon). Have Napa replacement ~5.5 years. Started up when it was -32F back in mid-January in northern MN.
2009 CX9 - Original lasted about 5 years. Fleet Farm replacement was still going strong after ~6 years when we sold it.
1989 Mustang - Batteries Plus (Duracell). Only driven in summer, but lasted over 8 years and was still doing OK, but I replaced it ~2 years ago with Fleet Farm battery.
2007 Motorcycle - Fleet farm, Walmart, Menards - These all seem to last about 3-4 years.
2018 Edge - Original battery replaced by Fleet Farm 2 years ago. The original battery tested good multiple times, but I could tell it was getting weak.
