Yesterday I did a test using headphones with the Ben.  The BL-5C was charged
the evening before and was taken out of the Ben.  I then putit i n the Ben 
this morning and  started the music.  At 6 hours and 39 minutes. I stopped
the test when the voltage was again 3.65 volts.  So apparently the 
load from head phones and the load from PC speakers is about the 

Playing music for 6.5 hours non-stop is a good outcome, in my opinion.
