Battery OEM Mazda or OPTIMA
I have a pair of Optimas (older) and they're dead-ass solid.
They’re pricey but I’ve always sworn by Optimas
General consensus is that the yellow top optima battery is best. Also, the optima is the only aftermarket battery that has the vent hole in the same place as the OEM battery.
I found my first optima red top. It was dead when I found it. I just happened to have an agm battery charger/restorer. It took three days of sitting on the machine reconditioning, and then a day or so of charging afterwards. It held a charge forever. It was made in 05 or something like that, and it ran great until this year. I have since replaced it with a new one, and it works great as well.
I have an optima red top 34/78. Its incredible. Been almost 3 years in and no matter how much I throw at it on the trails I dont get dead cells. The individual gel cells are less perceptible to shake damage from rough terrain.
I’ve got yellow top optima. Hasn’t failed me yet :)
While I did that I went ahead and grabbed a Red Top Optima Battery. Got everything back together, it turns over great but it doesn't spark.
I went through two of them in a season in my trail Jeep. I think years ago they were great batteries and the quality was there but now it’s just a brand name but junk product.
I also have an 18 and replaced factory with an Optima Yellowtop. Did not last long at all which sucks, was excited to try a battery I've heard so much good about. Went back to OEM since I didn't want any headache and it lasted me quite a bit the first time. Seems like Optima has declined in quality over time.
Replaced my OEM battery with a yellow top and it lasted less than a year. Complete junk imo.
