   I used the break-in mode on some batteries, and when the process was   
   finished the cell capacity showing was about 15% of the marked   
   capacity. Now, I'll grant that these batteries might not be usable any   
   more, but that seemed a long way out from what I expected. I shall have   
   to see if they're usable and see what happens after a cycle.   
      
   You could enquire of their tech support people as to what's going on....
