Battery Tesla or OPTIMA

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.

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.

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.

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

I've owned an optima before. Will never buy another one. I used one in my 4x4 to listen to music while camping, play it until the sub cuts out, get a jump, charge it and repeat. Ended up damaging the battery and it would never hold a charge and struggled to start the truck after a weekend of camping. Tossed it out after 2 years.
