well you cant really tell accurately, you have to do that charging current check with a proper meter. The checks people have told you about here will work, but really, you need to have it checked properly with a quality test instrument. As I say, it's a 60 second job you are unlikely to be charged for. Then you will know for sure whether you are charging, and the battery is rewted, or you are not charging and the battery is ok. (the battery might be stuffed as well, but the charging circuit might be working ok.)
