Recently my friend came into possession of a used iBook G3 (I don't know the specs off hand; but it runs Tiger okay), and ran into a slight problem. It appears as though the battery doesn't fully charge, and loses power 5 minutes after it being unplugged. I've looked at the battery, and it appears okay--although possibly lose. I'm sure that Apple wouldn't do repairs on it anymore, but does anyone know why the battery might not be working? If specs are needed I can provide them. But its an iBook G3 running Tiger.
