Hello I am new to the forum but I was reading about the batter life of the MB (I have the 2009 MB). My battery has a negative amperage (-349) even though it is fully charged and it says its on AC power. Is this normal? Because isn't negative amperage mean that energy is coming from the batter but its on AC power as well.... If this has been addressed please refer me to the thread i just did a quick search but couldn't find anything. Also, I don't know if this matters but I am at cycle count 9 and 96% capacity (Coconut) and 97% (iStats) and its 3 months old. Full Cap: 5272, now 5111. Thanks for your help!
