I got my 2005 with the Varta in it in 2011, I thought I had better replace it after two years. It had never faltered once, I kept it charged for three more years. I replaced it with a top of the line lead/acid CTC battery, it failed in two years. With the remaining warranty I upgraded to a AGM battery, it hiccuped once after less than five years so I replaced it with another of its kind. The existing one has done three years thereabouts. You can never tell with batteries one minute they are great and then suddenly fail. Four years is about the most you can rely on them, less if used daily in cold climates. I keep my car in a garage that rarely goes below 3 deg.C. During its hibernation period. I still have only taken it around the block this year.
