raaizin, you live in New Jersey?
Just go to NAPA and pick up an 8448, which is a rebranded East Penn/Deka Group 48, fresh from across the river:
Battery Cold Cranking Amps @ 0 Degrees F : 730
Battery Cranking Amps @ 32 Degrees F : 895
Battery Reserve Capacity (Minutes) : 120
This is a 70ah battery, and is what we use in our '09 Mk5 diesel.
The OE batts are made by JCI, almost certainly in Mexico, as it is closest to VW's assembly plant down there.
I'll take the PA one over one made in Mexico.
