Battery OEM Mazda or OEM Honda

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.

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.

I drive a 2019 CRV and was thinking about a new battery, doing research man it seems like today's batteries don't last, I figured i got 6 yrs with a Honda so I stuck with their brand

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.

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.
