Hi there, I have had my Macbook Pro for 10 months now. The battery was at 99% health up until a month ago or so. Two days ago I saw that the battery health was at 97%, which was in order I figured. Yesterday it hit 81%, later in the day it was 79% and now (like 5 hours later) the health is at 70%. I checked it with Coconut Batter and iStat Pro and confirmed the mAh number with that of the system profiler. My battery has had 20 cycles and is not eligible for the exchange program (Macbook Pro Core 2 Duo, running leopard). Is there any way this is a false reading? Because it seems if this is going on my battery will be down to 0% health in no-time. Thanks for any advice.
