vs
Battery Deka or OEM Audi
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.
Pros: lithium ones better
Cons: drains quickly
My current dead battery is a Deka - lasted 3.5 yrs, can't complain.
Pros: lasted 3.5 years
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.
Part number: ETX20
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.
Pros: works like a charm
Part number: ETX14
In sum, I can fully recommend the Deka ETX30L battery for long-term and continuous use in our cars.
Pros: long-term, continuous use
Vehicle:
Porsche
Part number: ETX30L
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.
Pros: reliable lightweight battery
Cons: trickle charger needed
Vehicle:
Porsche
Part number: ETX30L
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.
Pros: best fit, high capacity
I have had excellent results from a Deka Intimidator 9A48 High Performance AGM Battery Deka / Remy part # 9AGM48 installed Dec 2010
Pros: excellent results
Part number: 9AGM48
Sounds about right for a dealership, just had my battery replaced at a euro shop and it was 448 total
Pros: battery replaced
Cons: expensive
Vehicle:
Audi S3
Switched to a stock mk5 4cyl battery though as the Deka couldn't handle sitting for more than a couple days without being on a trickle charger.
Cons: couldn't handle sitting
Vehicle:
Volkswagen Golf
