Battery OEM Mazda or ODYSSEY

Being designed for industry they have a reputation for much longer life (up to 10 years) and better performance at cold temperatures.

Odyssey batteries have served me well. AGM. My Benz has the battery under the passenger seat so I it’s irritating to change. My last Odyssey lasted 9 years and didn’t fail: I just decided to change it as a matter of maintenance.

I'm on my second Odyssey Extreme (first one lasted from 2017-2022) and they are pretty good. I got the 34R-PC1500T. I give it a charge once every month or two with the Odyssey charger.

Odessey batteries . 5 years in AZ heat and still cranks . IMO it’s the only one I get my monies worth.

I went with Odyssey Extreme gel cell and its worth the price!

I'd like to say Ive had good luck with the Odyssey but it has maybe seen 100 kms in the 7 years since I put it in so no comment on the quality of the battery.

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.

My battery died last July at exactly 2,5 year mark. Mazda OEM battery is a cheap trash and so are the replacements too.
