NAPA. Only had one go bad early after my old truck damaged it. They replaced it quick and easy. Plus they’re located everywhere.

All good suggestions, if your going to buy a battery then get it from a national seller. As suggested these are gapped. Cisco, Sams club, Walmart, Autozone, ORelily, and even Napa. That way you can get it replaced if under warrantee almost anywhere. I buy from Sams club for my 6 Volt Gold cart batteries and I scored a HD 950 CCA battery from Walmart for my chassis battery.

Jay Leno swears by the Optima hello top (?) for his cars. They sit on trickle chargers and don’t off gas and promote rust and rot.
More $$ though.

some people say Optima batteries are not what they used to be, but others say they are great.
I have to admit, my coach starting battery is a optima blue top. My in-laws paid probably close to $400, when they were doing their fishing thing and had the nice boat and wanted the best trolling motor battery money could buy..... When they sold the boat, they kept that spendy battery, and maybe a year of looking at it in the garage they gave it to me thinking I should use it in my house bank. I would drag it with me a couple weekends we were off-grid to maybe use as a second battery, Then my 2nd new since I had owned the GMC battery went bad, so I put that battery in as a starting battery. so that battery still seems to work great, and is probably 6-7 years old.
my other experience, is I have a blue top starting optima battery in my Mastercraft boat. that battery probably has been starting my boat for 14+ years now. I had cranking issues with that boat when I first got it, and had to jump it a couple times. I then replaced the cables(like 8' long- battery is up front) with made cables from work we use for our construction equipment, and bought that blue top battery at that point. that had to be a over 15 years ago.
so my luck with Optimas are good, but those batteries are older when some claim they went bad. The AGM's also seem to not develop any corrosion issues.

I'm experimenting with a $60 wlamart battery, It will be interesting to see how it does.
It sure cranks ice now, I'll tell you that.
Biggest issue is it's side post only, so I have to figure out how to connect a boost cable
The starter rebuild guy says this starter should draw 150 amps, but that might be in a stall condition

These engines don't seem to need a whole lot of cranking power.
I did measure the cranking current at some point, but I do not recall what it actually was but I was impressed by how little it took.
This was with my overhauled 455 and a recently rebuilt 10MT starter.

Old Optimas WERE good and lasted. So that data while encouraging is now outdated because you can’t buy the old ones any more. 😆

I’ve found that battery care makes a bigger difference in battery life than
brand. In my runabout boat which sat idle every winter I would have to
replace the battery at least every two years. Once I added a battery
disconnect switch on the negative terminal AND kept the storage area heated
I never bought another battery while I owned the boat. 6+ years. I know
it’s a pain to pull the batteries out of a GMC but if not used in the
wintertime and not stored in a temp controlled space, pulling the batteries
will save u $

I have one friend that still buys optima batteries for his vw's, and says they are still good. If you ever noticed 95% of VW's have a battery size hole in the floor under the rear seat where the battery used to sit. So when you restore one, you are best to put a AGM in so you don't have to replace the floor again.
What is interesting is optima took the time to explain themselves on their website:
https://www.optimabatteries.com/experience/blog/optima-batteries-suck-the-truth
If I was them, I would of paid for a different URL, so it does not seem so biased? Who knows.
since I live in MN, I know not to let a battery go dead, so that might help... but I did have 2 Lead acid go bad on my coach. I bought some High cranking amp lead acid starting batterys. I was told that is not always a good thing because some of the higher cranking amps in a smaller case, the plates can be closer together, and can short out easier. But I used to go by the thought that if they sold a 900 cca battery in the same size as a 750. I would spend more for the 900. I have seen this also with my friends TDI new beetle. It takes a higher CCA and more expensive battery then the standard beetle. And he is on his 3rd battery, all replaced under the warranty time frame.

Since you live in MN are AGM batteries compatible with cold climates?

yes. I would say AGM are preferred for cold climates. The only downside is the cost.

Matt,
Tell us what the results are when you try to rescue the old Opitma's. I just accidentily had a new Costco battery fall to 7.9 volts because of a combiner shut down. Putzed with the combiner and it reset and seems to be working normally now but now I don't know if I can trust the Costco battery. The Optima AGM's might be worth the expense if they'll recover from an incident better than flooded.
