Battery OEM Mazda or Duralast

The other one (duralast one) has a better cca and will perform better in the winter months.

This is really straightforward to do. I replaced mine last September and was concerned about coding or needing to go to the dealer. My 2017 required none of that. Just take the old battery out and put a new one in. You'll have dash lights on afterwards, but all you need to do is turn the wheel all the way to one side and then the other.

I replaced mine in my driveway with a same size AutoZone Duralast Gold. With a coupon, I was out the door for less than $200. The car wintered outdoors at a Vermont ski resort and always started.

I JUST replaced my wife's 2013 Beetle battery with a Duralast from Autozone.

2014 Mazda 3, about 65k km.\n\n2nd battery only because I left the lights on one time a few years ago and needed a replacement. Nil problems otherwise.

My battery conked out at the normal time after 6 years. But it still didn’t give me any warning that it was dying. 2019 Mazda 3 here

Mazda OEM batteries known for underpowered and short shelf life. If you are in any kind of extreme climate for more than one season, there's a likely chance of failure.

162km at 42% battery is still kinda poor for 2025.

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.

The OEM batteries are shit. It died around the two-year mark.
