    I just got a new MBP 15" today, and for some reason my battery health is at 98%. Shouldn't it be at 100% when the machine is brand new? :confused:

    Is it useful in anyway to wait the 5 hours before recharging the battery ?

    Your battery is probably fine. Once the battery is fully charged, it slowly begins to discharge even if your MBP is plugged in. After it reaches 95% or so, it begins to recharge again. Your battery was probably charged a a few days ago. It should reach 100% a few minutes after you plug it in. If it doesn't, calibrate the battery.

    Be patient and wait. The battery needs to rest for a few hours in its discharged state.

    Exactly. I figure, Play with it all night on full battery when it's plugged in, then when you want to go to bed, stick in a DVD, set it to play (muted of course) and leave it. When the battery runs out 3-4 hours later, it will go to sleep for 5-6 hours, and then, 10 hours later when you've had breakfast and brushed your teeth, it's ready to be recharged and used!
