Battery OPTIMA or OEM KIA

The nice people at Optima would love to hear from you.

I put an Optima Yellow Top battery into my 2018 OB 3.6R because the CCAs of the stock battery were pitiful (490 vs 720). Maybe check out other brands aside from Duralast? Also, get something that’s way beefier than the stock battery, especially if you live in hot or cold climates.

I don't see it as overkill. It might have unused capacity, but I'd also rather have a battery that stands up to more than just enough.

I e been happy with them in my last 3 vehicles.

I had an Optima red top in my 89 4runner and that thing lasted for 12 fucking years. Needless to say I bought another one.

Just did that on my 19 gsw, no battery management extra thing to deal with, just the two connectors and obd11 for coding to fleece (not binary agm). Only issue I have is the battery blanket doesn't fit the bigger size.

I bought an optima just because it and it's custom hold down looked cool. Unfortunately I let it sit with no tender for over a year and it discharged almost completely. I've been able to nurse it back and it is functioning at this time, but not sure it will hold a charge. We will see. I'm happy with it otherwise.

Optimas quality fell off hard when they moved manufacturing to Mexico. They've been riding on their previous reputation ever since.

I went through two of them in a season in my trail Jeep. I think years ago they were great batteries and the quality was there but now it’s just a brand name but junk product.

I also have an 18 and replaced factory with an Optima Yellowtop. Did not last long at all which sucks, was excited to try a battery I've heard so much good about. Went back to OEM since I didn't want any headache and it lasted me quite a bit the first time. Seems like Optima has declined in quality over time.
