Battery OEM Mazda or OPTIMA

The OEM tundra batteries only last me 3.5 years at best. I always replace with an Optima battery.

I always buy an Optima battery for all my cars cuz they last a lifetime.

When I replace mine I went with the Optima Yellow Top. Seems to be hanging in there 6 years later.

I've never had a problem with one

I had a couple of Optimas back in the early 00’s that I took from truck to truck to truck. I had a couple of them for about 10 years. they used to be nearly indestructible.

My 09 yellow top just bit the dust. I was able to get it charged back above 13v but it's so old I didn't want to risk it with winter coming.

I replaced it with an Optima Yellow top battery. It lasted just shy of 3 years. Replaced it in July with another Yellow Top under warranty.

Optima batteries have, in my experience, gone downhill over the last few years. For their price, I don’t think they’re worth considering.

I have the same problem with my Mazada 3. Changed the battery while still under warranty and still does it. I don't leave anything pluggeded in and it still dies overnight. I purchased a battery tender and have to hook it up every night or get a boost in the morning.

I purchased one because of my car stereo upgrade, thinking it would be a better choice. Within a few weeks, I noticed that my cranking was slow and labored. It is almost seven months later, and I find myself having to randomly jump-start my car. Note: At first, I was concerned that my audio amps were not turning off properly and checked to confirm that everything was off. I think I may need to go with a different solution now.
