Best Battery for Volkswagen Passat

Update: it was just the battery, everything works fine after replacement and coding/adaptation. No error codes. Thanks everyone

Halt nur die Klassiker, alle 15j mal eine Batterie tauschen oder die wasserpumpe.

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.

I bought my 2008 3.6 4motion wagon a little over 3 years ago. It came with the original OEM battery, part number 4F0 915 105 E, and I was both impressed that it lasted that long and curious as to how much longer it would last.

just replaced 4 year old battery in my 2010 Wagon. It was not really a rocket science but it was nice to have a write up nonetheless. The biggest issue for me was to figure out group size for my battery: supposedly both 47 and 48 work but I wanted to get an exact model. After some online research and hard measurements it was clear my current battery was group size 48. Went with Bosch from Pep Boys for 108 (with tax and after 30% coupon). Despite the car being without the battery for 8+ hours, I had no issues with codes, errors, etc. The only thing I needed to adjust was the time.

Next battery I am going to put in my Passat is going to be something made by Exide . I mentioned before that I changed my OE battery in the winter 2007-2008, was concerned with low temperatures of this winter, but battery seems to do very well, started at 9*F and still work without a problem.

Went with an Optima at Wal-Mart. $100, no issues.

My Passat still has the battery it came with lol 6 years in the Arizona weather, I'd say that's pretty good.

On a Jetta, it will leave you stranded, and it being a VW, the symptoms will be nothing like a dead battery, most likely.

I compared the dimensions of both batteries (stock vs Optima) and the Optima is shorter, skinnier, but like 1/4 wider. Optima did not fit, or would not fit without modification to the positive terminal. Ordered the OEM from Keffer.
