Yeah they use undersized batteries, but just buy a good one and that's the end of it. my 2019 Legacy had is original battery after 4 years when I traded it in.
Yes. Subaru batteries are hot garbage. Go third party all day. I stand by any AGM I can pick up at Autozone, since they stand behind the batteries they sell.
I use a Group 27 battery in my Mustang and have found Bosch to work very well for me.
My dealer replaced the battery, updated the firmware and did a parasitic drain test.
Put a new Bosch AGM in.
Probably the easiest car to swap a battery on imo. Just remove and replace, negative off first. Bosch is good quality, but not required...Use 80Ah 12V.
At one time Bosch batteries had a terrible reputation but they now have their quality control back on track.
I bought these both for the same exact car but both the box and product appear very different, and the bottom set ended up being ridden with parasitic drain!
Bosch batteries are no poorly made in china
Subaru's factory batteries suck. I've had to replace them in several Subaru's that were only like 2 years old. Doubly tough if the car is just sitting for a period of time between uses.
