Battery OEM Mazda or OPTIMA

I put an Optima Red Top in it when my tester showed it below 75% health, about a year ago.

IMO, the Optima Yellow top is your only option. It will last 5-10 Years.

Absolutely not true. I use an Optima battery, works great. Have for a few years now since my 2nd garbage oem battery went out. Or was it the 3rd?

I installed an Optima yellow top in my 2023 OBW. Works fine!

My wrx would be parked for long periods and I had optima yellow tops. I liked how hard it cranked, good for e85 cold starts. But wow, after the second one went flat I stop getting them. Bought some random battery and it\u2019s been holding charge no problem.

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

Red Tops are sh* and have been for 10+ yrs at this point. \nThe last 3 or 4 I had didn't last 2yrs and I got warranty replacements, which also lasted 2yrs. For $300+ they are sh*.

My brother and I both have/had 6 speed 2015 Mazda3 (me the hatchback, him the sedan), and both of us had terrible issues with the Mazda brand batteries.

One day my alternator went and killed the optima battery

These are excellent cars but for some reason the batteries they use are bad. I had a 21 Mazda 3. The battery failed in 2023. They replaced it under warranty. The new battery lasted literally less than 6 months.
