Optima Red Top has been treating me well.
I like AGM batteries. Using optimas now, whenever these finally die I'll try another brand. 4 years in now and I can't notice any loss of capacity yet. They work amazing when it is like 0 degrees F, too.
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.
My original vw battery made it 8 years and 170k miles, but 10 years is pretty damn good!
I've had an Optima battery for several years. Still cranks my G20 van as if were brand new.????
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.
Optima used to be a big name but they switched manufacturing to Mexico and ever since they just don't hold up.
Optima are junk now as well since they were bought out a few years ago.
Optima has been garbage for about a decade now, ever since they were bought out and production moved out of the country. Quality immediately took a huge dive.
