Battery Exide or Deka

I have personal experience with with both battery technology and the litium ones put the conventional small battery to shame. If I left my car with the small Deka that's in it for a few weeks without starting, or turning off the cut-off switch, the alarm and small draw I have from a wacky door switch would completely drain it.

My current dead battery is a Deka - lasted 3.5 yrs, can't complain.

Me too. Using a Deka ETX20 right now. Scooped it for $85 shipped from Tri-State Battery. I just got my car back on the road, so I haven't seen how well it holds its charge without running the car every day though.

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.

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

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.

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.

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

My Tiguan factory battery was an Exide and it failed after 2 years, mostly in the Northeast US weather.
