Battery Energizer 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.

I have a snap-on torque wrench and duracell keeps doing that, I switched over to energizer and it stopped.

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

I'm still running on the original battery, which does surprisingly well until subzero temps set in, and then the poor thing just cries a lot and breaks my heart, so I jump it with my Noco and things are fine.

I had this problem with my 2019 Forester in stop and go traffic on the Dallas North Tollway. I was able to force the car into park and shut it off and back on manually, and this happened about a half dozen more times before my dealer finally admitted that there was a class action on those batteries. I’ve since had it replaced two additional times under a labor warranty. Like I guess it’s fine because it’s free, but very annoying that I bought a Subaru for reliability and I’m in the shop at least every 9 months for a new battery.

The auto start/stop failed to start the car today while waiting in a left hand turn lane at a red light in traffic. Potentially dangerous situation for anyone. Fortunately the person behind me got out of his car and pushed my car across two traffic lanes to the right curb. The Subaru dealer told me last week when I had the 42k mile maintenance done that the battery was fine based on a battery test. I had specifically asked for the battery to be checked because the starts sounded weak. Now I’m back at the dealer after the failure incident and the diagnoses is a bad battery. It is not safe to have the car automatically shut down on the road when the battery does not have the power to auto start.

I started using Energizer a few years ago after EVERY SINGLE DURACELL BATTERY in a 24-pack I bought corroded just as badly as the 1st battery on the left in your picture! This was regardless of whether the battery was in a device like a clock that was always running, in a device that is used when needed like my flashlight, or stored in my home office.

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.
