Robert, socketed meaning you can take the silver battery easily out from it (pop it out). I believe that yours is soldered to the board, that is unless someone has previously modified your B1230-IV with a socketed battery.
Let me make it a bit clearer for you. If your battery's surface looks like it's covered slightly with a brownish wrap around it, such as the one seen in
this picture, then it's soldered (non-removable).
