Battery Deka or Duralast

Great thread. I have used lightweight batteries in all of my builds. Dont buy Braille or any high end BS. They are all rebranded Deka. Ended up grabbing a etx14 power sports battery from autoquest for $70. Same as the Deka ext14 just rebranded.

I ended up purchasing a Duralast Gold from autozone. It's actually Manufactured by DieHard of Sears. it's money back for the first 3 years. you get half your money back if it dies in years 4 or 5. Oh well lets hope the Duralast treats me good.

In sum, I can fully recommend the Deka ETX30L battery for long-term and continuous use in our cars.

I have some extended experience with a lightweight battery in my daily driven 2006 Boxster S, which is well known for the demands it places on the battery. In spite of that, I successfully used the Deka ETX30L (21 lbs.) for almost 3.5 years.

2 weeks ago, I brought in a totally dead, 16 month old Duralast battery to Autozone. The girl threw some meter thing on the battery, saw that it was bad, and swapped it out for a brand new one.

EDIT: Confirmed fitment (duh) and ordered the Deka through Batteries Plus. This battery seems to be best fit as its reserve capacity is nearly double that of the Optimas.

I have had excellent results from a Deka Intimidator 9A48 High Performance AGM Battery Deka / Remy part # 9AGM48 installed Dec 2010

I don't recommend anything less than the DEKA ETX-20L for a car that see true street duties. The ETX-14 is 200 CCA @ 12 lbs, and the 4 lbs weight loss isn't worth it for 70 CCA loss on a small battery in charge of starting a car. The ETX-18L does 270 CCA @ 16 lbs and much more suitable for our 4 banger application. The ETX-18 however is the one I recommend to 95% of readers of this thread. It cranks out 300 CCA at 18 lbs, which is still plenty light.

My 2.8-year old mk6 GTI OEM battery started to show signs of aging about a month ago. It took longer to start when the car is cold and finally it failed to start yesterday. I called VW roadside assistance, got a jump start and went to Autozone, bought a Duralast Platinum AGM battery with size H6/48 . More to follow after the pics.

I had a duralast battery that I had originally bought for my beater mk2 that ended up in the Corrado, it then let go last week after only 11 months. I would go with the Bosch at all costs.
