Battery AC DELCO or OEM Subaru

I have a 2019 got a discounted replacement battery at the dealer and the new one is much larger (more powerful?).

I'd recommend AC Delco - had 2 batteries from Repco (made by century) for my VZ Commodore Wagon and returned them both for dropped cells within a month of fitting - had no issues with the AC Delco at all, even leaving the car sitting for over two weeks it still started first turn of the key

I have a 2023 touring with the same problem. Dead battery multiple times within the first few months. The dealership put in a new larger battery (900 cca) Subaru brand, had to take out the factory battery tray to make room for it. No problems as of yet.

Subaru OEM batteries can be pretty shit in cold weather. Even the service department at my dealership admits this. I eventually fed up with my Subaru batteries chugging in cold weather and replaced them with Interstate AGM batteries (with more CCA). I haven’t had any troubles since.

Any tips or advice before I fork out money for a new battery? I have some anxiety hoping its not the alternator dying, or less likely the starter. All things point to a slowly dying battery but I want a second opinion.

This happened to me during rush hour on a busy street! 2020 Legacy, they told me it was a known issue with the battery and replaced it for free. It was an incredibly stressful morning though.

I had this problem with my 2019 Forester in stop and go traffic on the Dallas North Tollway. I was able to force the car into park and shut it off and back on manually, and this happened about a half dozen more times before my dealer finally admitted that there was a class action on those batteries. I’ve since had it replaced two additional times under a labor warranty. Like I guess it’s fine because it’s free, but very annoying that I bought a Subaru for reliability and I’m in the shop at least every 9 months for a new battery.

The auto start/stop failed to start the car today while waiting in a left hand turn lane at a red light in traffic. Potentially dangerous situation for anyone. Fortunately the person behind me got out of his car and pushed my car across two traffic lanes to the right curb. The Subaru dealer told me last week when I had the 42k mile maintenance done that the battery was fine based on a battery test. I had specifically asked for the battery to be checked because the starts sounded weak. Now I’m back at the dealer after the failure incident and the diagnoses is a bad battery. It is not safe to have the car automatically shut down on the road when the battery does not have the power to auto start.

Replaced battery in my 2012 Chrysler 200 - after being in car 12 years - yes original battery - bought car off show room floor. Replaced with AC Delco 580 CCA - as per manufactures specs - exactly 2 months to the date - battery absolutely DEAD !!!!!!
