Battery Tesla or OEM Mazda

Yes. '19 M3 SR+. Mobile tech came, better battery than the original. Didn't want to get scr\\*wed with a shutdown.

Just got the notification on my 2019 m3p. Scheduled an appointment for Tuesday. 6 years and 1 month of ownership 77k miles in Ohio. Pretty good longevity if you ask me!

The batteries easily last 300k miles even if they're not well taken care of.

I\u2019m glad I have a Tesla with a 16v LV lithium Ion battery. Should last the life of the car like the HV battery.

My battery conked out at the normal time after 6 years. But it still didn’t give me any warning that it was dying. 2019 Mazda 3 here

As promised: 2019 M3 LR , 55k miles/88514km, latest Tesla Battery Health Test 83%

A bit worse than expected.

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.
