Battery OEM Toyota or OEM Mazda

As someone who bought their first Prius V (Lithium Ion- Australian Model) in 2013 No issues with any degradation in battery from 12 years ago.

After 16 years and 140k miles, our Prius battery is still going strong.

I bought mine last year 2016 SR5 4WD at 116k miles. I'm at 140k today and it feels like new. I only had to swap the battery because I forgot to check how recent it was when I bought it.

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.

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.

Had the same problem today... Battery died (ok, a few cold days in Belgium , nights up to -5°C) and assistance for jumpstarting it was necessary, luckily I had autoclub membership. Car is only 30 months old. We drive it multiple times a week for shopping and trips to the seaside. Checked the car in to the Toyota garage and test of the battery was negative, battery was dead. I was very pleased they replaced the battery with a new one under warranty!

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.
