Battery Panasonic 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 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.

I run Panasonic in ours, so far so good.

Replacing my battery recently

A new battery at 10k miles.

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.
