Outback has a Duralast Gold. If it helps, we’ve had some harsh -30°f days the last few years since I upgraded my battery. No issues what so ever on it.
Best Battery for Subaru Outback
I've installed the Odyssey Extreme battery in my Outback. These are AGM with 99% pure lead, not the alloy. Best battery I've come across.
I got a red top optima, put the subaru battery blanket on it. Good down to -10f.
I had my battery moment on my 2011 Outback, I bought a Duralast Gold 640 CCA and it's been working fine ever since.
So we bought a new 550CCA battery and installed it and it started right up. When I pulled the 18 month old OEM battery out, I was shocked at the CCA rating: 356. 356!!!! That's insane.
I've been running a redtop in my Outback for 8 years now. Still shows no signs of slowing down. Will be getting another one for sure.
The OEM battery sucks I upgraded mine to an AGM with an extra 100 or so CCA. A better battery will also let your auto start stop last longer. Stock battery would never last a stop light for while under load new battery gives me a lot more time even under load.
However, I have had nothing but bad experiences with Exide batteries. I've bought three, and all have died within 2 years.
