Battery Panasonic or OEM Mazda

My original Panasonic lasted seven years in my car when new

After the original battery, i replaced it with a Panasonic battery (nasa ₱5k that time) in 4th quarter of 2019. Etong panasonic battery life, last June 2024 ko lang napalitan (after 4 to 4.5yrs of service )????

Out of stock yung Panasonic so pinagtyagaan ko nalang yung Motolite priced at ₱7k recently (shucks i hope this battery lasts kahit 2yrs).

The Mazda OEM battery only lasts 3 years it seems. I have a 2021 and just changed the battery for similar reasons. It still started with no issues but it was pretty weak and was immediately noticeable after installing the new one. If you can afford it, the extra money for an AGM is worth it.

Still running on its original battery that came with the car.

I run Panasonic in ours, so far so good.

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
