I bought my MBP around late 2007. I just upgraded to SL and the battery indicator had a message that says "Condition: Replace now". Checking for more info, it also says "Replace Now: The battery is functioning normally but holds significantly less charge than it did when it was new." Searching around, I came across a battery checking program named coconutBattery and it says that my original battery capacity is 5500mAh but is now 2208 mAh. (40%) So now, 40% is my maximum charge. My MBP is not even 2 years old. Anyone else have the same problem with their MBP battery? Is this normal?
