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

This property specifies characteristics of the battery used. The format
|

|
|
of this binary blob is kept secret by CellWise. The only way to obtain
|
||
|
|
it is to mail two batteries to a test facility of CellWise and receive
|
||
|
|
back a test report with the binary blob.
