Battery Deka or OEM Subaru

Deka. Solid battery.

Of course, you can get a new battery, and I recently had a new battery 80% covered by the dealer, since this is a very well known and documented problem. (My battery was going on 6 years old, so I felt like the discount made it a good time to replace it anyways. The discount was specifically because it is a known issue, and supposedly the new battery is more powerful and “solves” the problem, per the dealer.)

My Mechanic had me get non-AGM style from Deka. I have the dual battery setup, and have drained my spare a few times already and it’s out performed the previous brands.

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

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.

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

Battery died around 50k miles.

My 2020 Outback OEM battery only lasted 3-ish years.

The OEM Subaru battery does not have a lot of reserve power.
