The battery for my early 2003 12" PowerBook G4 lasts for about 1.5 hours of YouTube playback and has no bulging and doesn't get very hot, but using coconutBattery I see that the current max capacity is being reported much higher than the original capacity. System profiler also reports the battery as having a huge capacity. Should I be concerned? What can I do to fix this? It causes issues with reporting how much power is left. It takes an hour to go from 100% to 94% charged, then goes to 5% charged instantly. It lasts for another hour after that. The same thing happens when charging. The battery has 75 cycles and is supposedly 4 years old, but it is from Apple. This is not the original battery, the original battery lasts about 10 minutes these days.
