Battery OEM Mazda or OPTIMA

2014 Mazda 3 with 322,000 kms, it's doing fine. I'm still on original engine, transmission and starter. I use it almost daily in traffic. The only problem is that the battery is slightly more costly than a standard one, which offsets the miniscule fuel savings you're getting from the system

Currently running a yellow Optima, 3 years and going strong. I don't recall what the OE battery was but it crapped out after 2 years in mild California weather.

I had an older optima yellow top last about 10 years. I miss when that quality was available

On my 2014 Leaf SV I put in an Optima Yellowtop and it lasted over 7 years.

I have a 10 year old yellow top Optima (not even the nicest thing out there) that starts a 440 (often 9 months between starts) every time. I haven't even put a tender on it in the last 5 years.

Optima seems to be the only brand of cylindrical Pb batteries for automotive use... pretty much every other automotive Pb battery is prismatic.

That's the first I've seen one fail this way.

Mazda OEM batteries are trash. Always have been. 35 years with Mazda and we stocked a ton of them.

The only time I had issues with my battery was the original one when it was on its death bed. But I remember needing to clean the posts a few times and it would start right up. Never was left with a check engine light but when it acted up it would do weird things here and there.

I’ve had my 3 for 4 years and I’m on my 3rd battery.

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
