Battery OEM BMW or OEM Subaru

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.

Regardless, while that’s sorta old for a battery, I have OEM BMW batteries going on 12 years with 89% charge capacity.

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.

Subaru are known for using cheap batteries, winter just makes it even worse. within the first 2 weeks of buying a 2022 Outback, i junked the battery and put in a great aftermarket one.

Wife’s Ascent had a factory battery that last maybe 2 winters. Replaced it was a yellow top and haven’t had any problems since. Subaru even gave us credit for it so that was nice

My car does not start well. I had replaced the battery myself, which helped it not be so bad.

I had Subaru batteries last me only 2 years in upstate NY. I kept getting them for free under warranty. I probably got 4 this way. Finally, the dealer said your alternator is bad and that's why they are going bad (completely bogus). I started going to a local mechanics soon after that and they told me that super OEM batteries are complete garbage.

I have a 2019 Subaru outback. The battery dies every two months and I am left stranded.

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.
