I see, so the batteries are still somewhat funcional and are keeping the 
"cpu" onboard running, just not the transmitter.  Thank you for helping me 
to understand this.

Just one more question:
What might happen when the battery fails completely?  will the satellite 
require new software to be uploaded just as some other satellites also do?
