vs
Battery Tesla or OEM Mazda
If I could easily repurpose the cells in my 140k mile Model 3 into home storage for my solar I would rather do that than sell the car. 3% degradation the car itself needed more work than a replacement battery ever would have cost.
Pros: minor battery degradation
Cons: car needed more work
Mileage: 140000 km
Stock OEM Mazda CX5 battery is weak AF. My 2019 battery died in Jan 2024 after coming back from Disney trip that lasted 7 days. Got one from Costco. Higher CCA for less than OEM from Mazda. Installed myself.
Pros: Higher CCA, less expensive
Cons: Stock battery weak
Vehicle:
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.
Pros: long lasting
Vehicle:
Mazda 3
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.
Pros: love the torque, silent driving
Vehicle:
Mazda 3
I have an early VIN 2020 MYP with 80,000 km; the diagnostic says 87%, so 13% drop in battery health. Range calculation at 100% SOC dropped 4.9%.
Pros: diagnostic says 87%
Cons: 13% drop in health
Mileage: 80000 km
The only issues my wife and I have had on our 2021 CX9 and 3GT are dead battery issues. And we had dash and reverse cams fitted, which run and film continuously. If our street is busy, they can run the battery flat within 2 days.
Cons: drains quickly with accessories
Vehicle:
Mazda
My car was sitting in parking lot with engine OFF and ignition ON - Android Auto was working and headlights/interior lights -> after about 15min music stops playing and I thought okay it's energy saver mode let me start engine.
But NOPE, there were some error messages, and engine couldn't start - battery was DEAD, I read battery are shit on new Mazdas and didn't want to deal with it myself and get it towed because of warranty.
Cons: battery dead quickly, no warning
Vehicle:
Mazda
Mileage: 45000 km
Mazda uses cheap batteries, I have had to swap them on my last two CX5s
Cons: cheap quality, frequent replacement
Vehicle:
Mazda
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.

Vehicle:

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.
Cons: underpowered, short shelf life, prone to failure
