*dbg python 2.6.5 Ted, you are most correct. The problem is that we are at that same 'indefinite' stage that TC108 has found with IEC62368 . A member of the SC contacted me through a customer, and it would seem that UL's rep has determined that things will have to wait until a second edition of 62133 to satisfy requirements from electric code, IEC, UN, etc. And according to this member, the transition WILL be pushed back (again).
Perhaps I can talk my employer out of this crazy battery charger business - too many amateurs to compete with...
