   13   The driver can utilize information from a simple-battery linked via a
   14   phandle in monitored-battery. If specified the driver uses the
   15   charge-full-design-microamp-hours property of the battery.

   29       This property specifies characteristics of the battery used. The format
   30       of this binary blob is kept secret by CellWise. The only way to obtain
   31       it is to mail two batteries to a test facility of CellWise and receive
   32       back a test report with the binary blob.
