I have also gone through 2 batteries in just over 2 years. The first was fully recharged quite a bit seeing as I was always working remotely. The second battery went through much fewer charge cycles since I was working from home and I was making attempts at improving the life of the second. Each of the batteries I purchased died out at about the same time. Unless I got two bad ones, it seems to me that mac batteries weren't of the best quality during the time of my purchases.
