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.
In my car (2021 Mach E AWD with standard battery), the battery state of health the first time I checked it was around 94% at around 48,000 kilometers. I’m not sure how accurate the car’s data is because it seemed to drop a percentage or so immediately after a couple of OTA updates. It sat at around 92% until between 80,000 km and 113,000 km, but now it’s says 92.5% at 120,000 km. Again, I’m not entirely confident at how accurate the car’s information is, but my range is still about the same as when it was brand new. I think I’m past any danger of manufacturing defects, so I don’t have any reason to suspect that the battery won’t easily last a couple hundred of thousand kilometers more.
Kakabili ko lang ng Everest, so far no problems minus that one time na itinirik ako ng wala pang 2 months of ownership kasi defective yung battery. Common issue siya that happens around 6 months - 1 year, kaya ina-advice na palitan agad yung stock battery sa fecp na group, pero ang OA ng 2. months. Granted, napalitan naman agad battery for free pero ang hassle parin.
The Ford battery in my Fiesta is as old as car so 10 years but despite still being able to start car it would only charge to 50% of capacity
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.
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.
