Battery OPTIMA or OEM KIA
I have a red top in my XJ and people say the quality has gone down every time Optima is mentioned but I've had nothing but stellar performance from mine. I was about 7 miles in on a trail 2 weeks ago and my alt died. The battery got me back to the main road before it died enough to not run the engine anymore. A little more than an hour back out and some gnarly rock crawling.
I got 7 years out of my 2010 6V Red Top in the Porsche which I replaced with another and recently purchased a 12V Red Top for the Bus. Battery is more expensive than standard but getting 7+ years vs 4 makes it worth while.
The Optima in my Infiniti is 10 years old and still going strong but I've read so many bad things about them recently, I would be hesitant to buy another one.
I have a red top in my 4 motion b6 Passat. I have not had any electrical issues. As long as the optima matches or exceeds the oem battery cca you’ll be fine.
We have one in our 2007 and it has been going strong for almost 7 years.
Optima battery recommended. Expensive but large capacity for emergencies.
So I've been looking to replace the stock battery doesn't seem to hold a charge as well as before. Always wanted to put an Optima Yellow Top in it
My optima failed after 1.5 years
Johnson Controls ruined Optima.
Optima batteries have taken a hit in quality in recent years.
