I know this subject came up on this list a long time ago..... My iBook G3/500 has a replacement battery from Apple that is only a year old and it holds a charge very well (several hours). However, no matter how long the laptop is plugged in, the charging indicator never goes above 98%. The battery seems to actually be fully charged, it is just off on its calibration perhaps?? Does anyone know the fix for this? Thanks, Tom
