Anyone have a reliable place to get a good Varta Battery for an FTYPE R stateside. Seems like lots of retailers in Europe but I cant find any here in the States.

 

It doesn't have to be a Varta any good brand AGM of the right spec and size/shape will do the job.
Plenty here have fitted others such as Interstate or Duralast (I think these are well known US battery brands!) and the size H8 rings a bell.
