Battery Duracell or OEM Volkswagen

OEM Volkswagen of America has the best battery for your Corrado. It's currently $110 and worth that ****. You look at the top of my battery, it says Manfacture Date December 2005. This thing has gone through hell and back. Everytime, it has cranked that starter with no issue.

i had my left side battery replaced about a year ago and i watched the shop (not a dealer) do it. the starter battery was not disconnected, the hardest part seemed to be lifting the battery out (fits tightley in there and isn't feather light).

Jack on my visit the battery was also replaced. Part# 000-915-105-CE. They also replaced two modules that were causing a drain on the battery.

The VW service called yesterday (I took my car in that morning) and stated the battery (driver side) was bad, and was replaced ($347, if not in warranty). Other battery OK.

So ever since I put subwoofers in my car they seem to be killing my batteries. My original battery lasted about 2 years (car was barely used for these 2 years), battery after that lasted a year (replaced last summer), and now it seems as if my current battery is going. I wanted to grab food before going to work yesterday so I got some food at Mcdonalds and sat in my car for 20-30 mins eating and listening to music. I went to fill my car up with gas after work (gas station not even a mile away) and the car barely started, normally it turns over very quickly, you could tell the car was REALLY struggling due to battery (everything dimmed as well). This was at night so my headlights were on while I was filling up. At the beginning of summer I went to a drive-in and was able to watch an entire movie without my battery dying. The battery is a Duracell with 725 CCA and 890 CA @ 32F
