Battery OPTIMA or OEM Mercedes

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 replaced it with a new optima battery anyways. Still have the issue.... Moved onto the car alternator. Tested it with my DVOM and it was giving out 13.7V at idle.

My last Optima was outlasted by a Sears Die Hard.

Optima was once a great battery. However a few years back they moved their production and since then its been a nightmare of failures.

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.
