I’ve got a 2007 STi that splits time with my truck as a DD. As such it gets driven only a couple times a week, and since work is only 3 miles away from home it doesn’t necessarily get run for long periods of time when it does run. After almost 10 years it finally failed to start for me the other week. I was able to charge the battery and get it started, but I suspect the OEM battery has probably given up the ghost at this point.
Rally Subaru in the snow for your time.
What do I get for a replacement battery? The replacement battery needs to be able to get things started even when it is stupid cold out (-25°F). Do I just get the highest CCA battery I can snag from Walmart, or do I spring for an AGM? The OEM battery has always managed to get things started in the cold, even if it can be pretty sluggish turning things over the first thing in the morning. Car is kept in an unheated garage, so that helps some but -25°F is still -25°F.

I asked a similar question this morning—wacko posted a link to discussion on AGM v lead acid, you may find some other useful info there, too:

Though I’m generally not a big fan of the quality of Walmart items, I do have to say they have a pretty good warranty on their top model battery (EverStart Maxx I believe it is). The warranty is 3 years full replacement, and then pro-rated for several years after that. So if the battery fails during the first 3 years, you bring it in for a test, and it if fails that you get a new battery with 3 MORE YEARS of warranty.
The warranty is on the battery, not the original purchase, so you can keep getting free replacements every few years if you have a car that likes to eat them.

Up here oem batteries last me about 4-5 years, so 8-9 years on oem is good.
I put AGMs in all my cars / toys. Difference in price ain’t that bad.
I have to go buy a new AGM battery for my snowmobile.

Just put a higher cca batt into the Forester. Oem lasted almost 9 years.. went with lead acid because the difference in price wasn’t worth the advantage for a family daily. Subaru factory cca was 480- replaced by a 640..

Optima red tops are always good to me. But any agm would be good. Maybe setup a maintainer hookup that you can plug in during the long periods of sitting? I used to do that for my truck that sits parked for the winter, but now I just yank the batteries and charge them in the garage before I reinstall in the spring. But it was pretty simple to rig up a plug using a trailer wiring pigtail.

Hell, I am only in New England and the stock batteries only lasted 18 months. I say batteries as my truck has 2. I replaced them and at least the replacements have been going strong.

I would try and get another oem. If the first lasted 9 years which is great for new England standard I’d stick with that.
maybe a battery warmer if worried about those -25F days

First of all....get a battery tender. If you live in temperatures that cold and don’t drive your car every day, you can expect that it may not start every day. Secondly, you could just DD your STi and so it wouldn’t be sitting. Also, AGM’s deal with the cold much better than lead acids in my opinion.
