Try putting an AM radio near the charger and listen to the changes in RF
emission as it goes through its various charge conditions.  I'm finding that
this works, at least for switching-type chargers.  Someone may have to tell
you the state of the LED the first few times you try this, and it probably
won't work if this is a conventional charger.
