Battery OPTIMA or Deka

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.

Deka aka East Penn is the best battery manufacturer out there. They dont leak as much, they last typically 3-6 years depending on circumstances

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.

Used redtops for years. Had a couple go bad, but 3 year free replacement warranty solved that.

I just upgraded mine a few weeks ago, ended up getting a DEKA AGM 9AGM47 More CCA and far more reserve capacity than the stock battery (120 mins) I was at ~35k miles and my OEM battery was failing fast.. I couldn't leave it in the accessory position without the engine running for more than a minute or two or it would barely be able to crank. The OEM battery is crap as far as I'm concerned

Optima isn't nearly as good as it used to be. I've owned a lot of their dry cell batteries and they've gone to **** over the years. They don't hold up well to this kind of use, and if they drop below 11V they **** the bed.
