Battery OPTIMA or Duralast

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,

My last experience from them was a yellow top from 2015 that I got for my '01 Mustang. Had it for 4+ years starting up just fine and survived despite having been drained dead 5 times or so. Sold the car before the battery died.

I had one. It lasted a good seven years. Still good quality, its worth it if you can swing the price.

The yellow top is what I have in my car and there is one issue I have with it, the amp hour rating. The yellow top is only 38a/h where the OEM is about 45a/h. This will lead to the inverter using a lot of energy charging the 12v battery and decrease fuel efficiency.

Purchased one a few years ago, bad a year later and yes I have a good battery tender.

The "new" Optima in my RX7 died after a very short life

Optimas are garbage. Mine didn't survive a 3 month work assignment. The battery was less than 2 years old, and fully charged when I left. Dead when I came back. Blew up like a football when I tried to charge it.
