Battery Deka or Duracell
Deka is the best I’ve found.
Pros: best performance
Replaced with: Duracell Ultra Platinum AGM Battery SLI49AGM
Vehicle:
Porsche 911
Part number: SLI49AGM
Yes and you can go the route I suggested earlier, with a Group 47 AGM , Deka brand. I paid $135 for mine 4 years ago at Battery Mart. Fit is good, just add a wedge under the battery hold clamp. Cannot leak acid due to the design. I run diesel farm tractors, too. AGM's are the only batteries I can get a decent life from due to the vibration. The extra capacity over the standard lead acid batteries is great for the cold morning diesel start. My point is that they are quite durable. An AGM for a Rabbit is not overkill when you consider the quality problems in regular lead-acid batteries these days.
Pros: durable, cannot leak acid
Cons: add a wedge
Vehicle:
Volkswagen
Part number: 47
I've always been a fan of Deka batteries, their ETX15 should be the correct battery.
Pros: good batteries
Part number: ETX15
Deka aka East Penn is the best battery manufacturer out there. They dont leak as much, they last typically 3-6 years depending on circumstances
Pros: best battery manufacturer
Cons: depends on circumstances
I'm using Deka. But it's a good choice. I haven't any problems with it.
Pros: good choice, no problems
Deka batteries are still good quality. They are somewhat harder to find than other brands.
Pros: good quality
Cons: harder to find
Standard sealed lead acid batteries from duracell will work great for several years.
Pros: work great for years
Fall 2016 Update: I just installed a new battery. It is a Deka Group 47 AGM. Cost was about 135$ at Battery Mart, 20$ more than the standard battery the store offered. It is odd in that the carry handle is square to the battery length. The specs say it weights 37-1/2 lbs. 600 CCA at 0 F. Two minor things: The battery foot flange is not thick enough to match the battery holding channel or the holding clamp. Some sort of wedge needs to be used. There are probably height adapters or spacers sold for that. Second, the hood release cable will need to run on top of the battery corner, unless you slide the battery out toward the radiator more than I want to.
Pros: 600 CCA at 0 F
Cons: wedge needs to be used
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
Pros: more CCA, more capacity
Cons: OEM battery is crap
