Battery OEM Mazda or OEM Hyundai

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.

my 2022 Hyundai Ioniq 5 has 71k+ miles and coming up on 3 years of ownership. I plug in when, where, how I want. ONE thousand charging sessions. It has ZERO range loss.....300 miles per charge still. I have no battery degradatiion. State of Health = 100%.

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.

Basically many of the oem stock items for mazda are fine, but have notoriously short life expectancy. They have to cut corners somewhere. Battery and tires are the ones I've noticed that are good for a couple years at most before they are ran through. So yeah, I've had a mazda thay needed a new battery after 2 years, one that needed a new battery after 3 years. Just how they go.

Worst part about Mazda cars - battery can silently die on you. Instead once you're ~3 years in you're gambling every time you go for a drive.

OEM batteries are crap, replace it with something better, preferably an EFB one. Also, a healthy battery should withstand that time and even more, so yours was definitely at its end.

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.

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.
