John, Most of the time these batteries are not replaceable (ie they are soldered to the board) and servicing of the board is not likely in the field. In this case, you need to provide service instructions with the battery statement. Now, if servicing is done at your factory, it simply means that your in-house procedures should follow the manufacturer's disposal instructions.
John, it is not UL only who sits on the IEC WG8 IEC 950 Committe. There are many manufacturers like you sitting on the committee. If you wish your voice heard, you need to join the group. Beware, it can become an expensive activity!
