I've got 620 charge cycles on my battery and I believe my MacBook battery is swollen. The bottom of the case is bulged a bit ( by the track pad ) and the trackpad itself doesn't seem to have the click depth that it use to have. Has anyone experienced this? Any ideas if Apple will replace this? My 1 year is up, the mac is about 1 year and 8 months old. Kind of disappointed, I've never had any issues with any mac batteries ( atleast not so soon ).
