We bought our new 2012 fw in August of last year (2013). A couple of months ago, the battery would not hold a charge. Since it had a 12 month free replacement warranty, I called a local dealer for the battery and the guy says to bring it in. I take the battery to him and he takes one look at it and says that it was made in December of 2010 and couldn't do anything for me, it was just too old. Since I had to get a battery I went to another dealer and bought a different make of battery. I also contacted the original battery company (Deka) and explained the situation. I provided proof of when I bought the trailer and yesterday I get a check from them for the replacement cost of the competitors battery. Kudos to them
