I received a friendly phone call from Steve Gomez at Springer. He explained that the battery cover is not available through their parts manufacturer as a single piece. When you order one, you get the entire plastic housing for the BP, that's why it is $23. APH does not carry that in their inventory which is why I had to go to Springer directly. They have only had three requests for a battery cover, including mine, in five years so it is not economical to stock them. I am satisfied with his response and feel that he is doing the best he can do in this rare situation. Peter
