As for the battery choice, I'd personally opt for the Varta. The main reason being the service life you have received from the original battery. I wouldn't worry too much about the Varta's lower rating as the original has seemed sufficient over approximately 6 years and most Phaeton owners are reporting excellent life from the original batteries.
Owner reviews for battery
i've got the yellow top, installed from the previous owner. it doesn't fit my battery cover too well, but boy does the yellowtop have plenty of CCAs, my start is much stronger than my friend's .:R32 (battery from dealer).
get an acdelco group 47 battery fits perfect is the identical size as oem and is probably wayy cheaper than an oem, i paid 85 idk how much oem ones are
Just get a good battery from a known "brand" manufacturer (Bosch, etc) - they will last much longer than a supercheapie
I just have a red top Optima in there. It is the only batteries I'll buy after the one in my truck went through so much hell and survived many years of abuse.
I got a Bosch Battery from Pep Boys. It was 90 bucks but it has a KILLER warranty. I forget exactly but it has road side assistance. 3 year free replacement and like 7 year total I think. Fit PERFECTLY. It looked exactly like the old stock battery other than the acid level thingy.
I replaced mine with an OEM battery from the dealership. Both mine and my wife's OEM batteries lasted 5+ years. We replaced hers 3 years ago with a Duralast or whatever - starting to leak at the terminal I'll be going back to OEM on hers very shortly.
Yup, that's the one. The R is for reversed terminals to make it a more ideal fit for our application. Sadly I couldn't find one locally when I needed it so I got the 34/78. It works but isn't a perfect fit as it does require trimming to get the clips on the distribution block to snap back in.
I had an optima yellow top in my Jeep for 3 years. Then all of a sudden a cell died without warning, leaving me stranded in the desert when I went to start it. I will never buy another one. The duralast I replaced it with has been in there for about 4 years now with no problems. It also cost less than half what the optima was.
we see many 2 year old Duralast batteries that have failed.
