Battery OPTIMA or OEM BMW

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.

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.

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

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.
