Battery OEM Mazda or Duracell

I've had good results from East Penn Duracell at Sam's Club. I just replaced one nearly 8 years old.

The best way to check is to go with a multimeter and get the highest voltage/closest manufactured date. Duracell might just be EverStart rebranded BUT NO the Walmart battery will last around 1-2 years, maybe less. If you want to make sure your covered with a good battery, that’s when you go to Advance Auto or AutoZone and get the battery with 3 years of warranty and swap it out right before the 3rd year ends and I find the batteries last me forever.

The best lead acid type of battery is a Duracell/East Penn hybrid/house AGM deep cell. These have thicker plates and are typically used for RVs and boats. They can tolerate deeper discharge and are less susceptible to damage (AGM). They sacrifice a little instantaneous current output, but that's not needed on an EV.

We’ve always had luck with Duracell in our cars.

The replacement battery I bought was a Duracell from Sam’s Club. Fit and worked fine.

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

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
