Battery OEM Mazda or OPTIMA

I have a VR6 swap that Sal at S&P did for me and we used an Optima Red Top.

I've had an Optima battery for several years. Still cranks my G20 van as if were brand new.????

I run optimas because of the extreme temps here. Can be -40 outside and over 120 in the summers. They've been great for my old 454 powered truck.

I’ve had mine in for about 3 or four years. The only thing I’ve noticed is I don’t have to change my battery every year now.

I had an Optima battery in my 2006 WRX for about 7 or 8 years before deciding to replace it with another Opitima battery. I ran that second Optima battery for about 5 or 6 years before trading in the vehicle towards a 2021 WRX. The OEM battery may end up turning over just fine when the temperature is -20F'ish, but Optima batteries have never let me down in the past.

Bought the Optima, not yet installed. Have had good luck with them, 5 yrs or more each,

I always liked Optimas, but I bought mine 2-4 years ago. I heard the quality has gone down but haven’t checked myself.

I got stuck getting an optima for my truck because the one that was in it literally exploded.

10 years ago, in Florida, I bought the red top battery for my F250 diesel. It blew up under the hood and sprayed battery juice on everything. It was only a few months old. Discount Auto replaced it for free under warranty. But I wouldn't buy another red top.

20 years ago optima was good. Now its 300 dollars for a 50 dollar battery. Used to get them super cheap as a jci employee and they would last made in Colorado but the quality control has been gone for decades.
