Battery OPTIMA or OEM KIA

I have become a BIG fan of yellow top optima batteries. Mine tests out OVER 1000 CCA (only about a year old) sealed- Acid can never leak out. Deep cycle, you can run it dead without damage. Good warranty, The the batteries are built to take extreme vibrations, and have a superior design to connect the plates inside with a more solid connection.

I put one in my car and it worked fantastic for 3 years no issues and is still going strong.

I have the Yellow top in my 1983 Scrambler and have had no problems with it. I treat it awful in winter I will go weeks with out driving it and then crank the jeep and go use the winch and lights sometimes idle for long periods and the not drive for a few more weeks. Cranks every time.

On my Porsche I run an Optima which lasts 7+ years and is a very strong battery.

I like them and that's what I use in my Toyota (Lexus). Had it a couple of years and so far so good. One neat thing about the Optimas is that since it's 100% sealed there's no worry about tipping it or having to wear gloves during transport and installation. It's also lighter.

Get an Optima battery and the battery minder - it's just a trickle charger that slow charges the battery to a certain voltage and then turns itself off. That's what I use in my S2000.

The only advantage to Optima batteries is if they are used in an environment where they experience very high vibration or need to be mounted in unusual positions. The longevity of them is no better than a good quality lead acid battery, so unless you're hardcore offroading or need to mount the battery upside down for whatever reason, they really offer no benefit.

Optima batteries have been objectively awful for years. Don't buy them.

Optima batteries are not as good as they first were. Optima batteries have gone down in quality after being bought out, after Johnson Controls bought them and moved production to Mexico.

I had an Optima that behaved like this and took it back to AutoZone, they swapped it out without much hassle.
