Battery OEM Chevrolet or OEM Mazda

Just last week I had to change the original battery, because I was abroad for almost three months and the car had not been started even a single time. I left it outside and it's been constant -1/-5 Celsius here. So naturally the battery went.

Our household got its first EV earlier this year, mainly for the daily 20-25 km commute form my SO, and it’s been the best car purchase we’ve ever made (only bested by my 3, which made it to 10y w/o problems this year). That “small battery” that once worried us (or more like we intentionally went with the smaller offering)? Barely a drawback - in the summer, a single charge lasts a whole week. This EV has become our go-to for short trips, and while cutting running costs by 2/3 was a big motivator, it’s now just a nice side benefit. I love the torque and started to love the silent driving. especially in a traffic jam.

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.

Still running on its original battery that came with the car.

What is the sound of one hand clapping? Does a bear sh1t in the woods? If the bear does, is the turd a uniform size and power that will work with attributes of all the other different sized bears out there?

Mazda uses cheap batteries, I have had to swap them on my last two CX5s

My cx30’s 2023 battery died as I was coming to a stop sign. As I was rolling to the stop sign my breaks failed hit the car Infront of me and the could not get my car to start.

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.
