Battery OPTIMA or Deka

I got the yellow top but it was worth every cent fwiw. Swapped to a yellow and feel like I could start first time every time in the tundra.

I've always been a fan of Deka batteries, their ETX15 should be the correct battery.

My yellow top in my mk1 is 8 years old. My yellow ro in my R is 7 months old. They're great.

I installed an Optima Yellowtop D35. The D35 is shorter than the Q85, but the terminal cover provided by Optima doubles as a base to increase the batteries height. Great design Optima! Immediately after installing the battery, the "Battery Management System Malfunction" message still displayed. Finally after leaving the car overnight, the message went away on its own. The i-ELOOP system is now functioning as normal.

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 an optima, have had others, love them. The only issue I've ever had with an optima is getting a severely discharged battery to take a charge, but through youtube i figured out it was an issue with my charger and started putting another one in parallel.

No they are garbage now. Source: we sell them at work. We also warranty them. Don't buy an Optima. Ever since Johnson bought them, they went downhill.

I've never been impressed with an Optima battery.
