Battery AC DELCO or OEM Subaru

I bought my last battery from Menards. They sell AC Delco batteries. They come with a full non prorated 3 year warranty at least they did last year

with the auto start/stop eliminator installed after 1 year of ownership (using the auto start/stop feature the first 6 months and manually disabling it the last 6 months), my 2019’s battery lasted 5 years and 160k km before it started feeling weak and was replaced as a precaution.

My 2021 with 84k miles was very similar. Even had the auto start fail to restart the car once when it was cold. I just had the battery replaced with the new larger size one and it made a huge difference.

Replaced original battery at 93,000 miles. I live in Detroit. Cold winters. I guess I got lucky.

Battery didn't outright die but it was weaker starting and with winter coming I didn't want to trust it.

The only issue I had with any of them were the shitty batteries in the first two.

My 2018 has had zero problems except for a recall for battery.

My OEM battery died in 17 months. Their replacement OEM battery died in three months.

Battery died last month at 39,000 miles.

Our ‘17 Outback went through 4 batteries in the 7 years we owned it.
