Battery Panasonic 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.

My 2019 Mazda 3 died on me randomly a couple months ago. The dealership ran a test on it and it came out fine. I changed it anyway as it was a stock 5 year old battery. It’s been fine since, even in the -20°C temps where I am.

I just replaced the battery on my eco drive from maybe 2008ish? Battery itself was 14 bucks on ebay, oem brand(Panasonic). Swap took 5 minutes.

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 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.

The only time I had issues with my battery was the original one when it was on its death bed. But I remember needing to clean the posts a few times and it would start right up. Never was left with a check engine light but when it acted up it would do weird things here and there.

I’ve had my 3 for 4 years and I’m on my 3rd battery.

Incan confirm they suck… i have a 2023 mazda and i have gone through two batteries. The second one died on me this week. Both were mazda batteries

Mazdas OEM batteries are horrible. Had the one that came with the car be weak so Mazda replaced it under warranty. Not even 5 months later that new battery dies, tried jumping and it was completely dead and a jump could not start it.

My'21 CX9 battery is weak, and i can clearly tell its low on voltage after sitting without being started for a week. Never tried playing music on battery though in this car.
