I bought my first Mac (the 13 inch unibody MacBook) last month and love it. However, I was hesitant about buying it because of the non removable battery. After a month's use (probably 2-3 hours each day), iStat Pro says that I have 98% health, 19 cycles, and 96% charge now. Is it normal for it to go down that much within so little time? Also, if I decide in the future that I need a replacement battery, how would I go about getting it replaced? Thanks.
