A battery cycle count of 60 is reason to worry. The definition of a "full" battery cycle is full charge to full discharge, in other words 100% to 0% battery charge. Normal use is defined as 1 cycle every few days. I've had my MBP 15" for about half a year now and I only have 25 battery cycles used. Don't worry, you have 1000 cycles before the battery degrades past 80% health, that is part of the warranty (only if you have the new unibody with non-replaceable battery).
