so I have had my MacBook for a little over 2 months now and according to iStat Pro that my battery's health is only 97% good. Is this good or bad that it has already lost 3% of its battery health in a 2 month time frame?
 
no thats fine! how many charge cycles do you have? you should have a health of around 80% after 300 charge cycles.
 
274 cycles and my battery capacity is higher than when it started. 😛

I use the AC adaptor most of the time.
 
I've had 7 cycles and i'm at 97% and my battery will only reach 98% on a full charge.

Have i got a bad battery?
 
so if i were to use the power adapter continuously would that affect the battery's performance?
