Battery OEM Mazda or OEM Subaru
Reviews
The Mazda OEM battery only lasts 3 years it seems. I have a 2021 and just changed the battery for similar reasons. It still started with no issues but it was pretty weak and was immediately noticeable after installing the new one. If you can afford it, the extra money for an AGM is worth it.
Pros: noticeable improvement with new battery
Cons: OEM battery weak
Vehicle:
Mazda
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.
Pros: new larger battery, no problems
Cons: dead battery multiple times
Vehicle:
Subaru Outback

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

My 2025 CX-30 battery is already showing signs of dying but I bought the car in April but then had surgery in June and only went back to work today so it sat for long periods and I do leave my dash cam in parking mode. It might come back some after being driven more or it might not.
Cons: showing signs of dying
