Battery OPTIMA or AC DELCO

If you do need one, optima is pretty good but expensive.????

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.

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.

my 2009 had an optima and it only lasted 2 years

I have only had poor luck with optimas

At 126,000 miles in 2016, we had the battery replaced with an Optima yellow top dry battery. It lasted around 2 years and was replaced in September of 2018 under warranty. Today, my car suddenly wouldn't start, and after getting a jump and going to Autozone, it showed the battery had zero charge. They didn't have another yellow top, so I got a wet battery, one of the only ones available. What sucks is I checked the warranty date and it expired 4 days ago. I'm quite disappointed that the average life I've seen with these are under 3 years.
