   36       The alert threshold that sets the state of charge level (%) where an interrupt is generated.
   37       If skipped the power up default value of 4 (%) will be used.

   41     description: |
   42       Certain devices return double the capacity.
   43       Specify this to divide the reported value in 2 and thus normalize it.
   44       SoC == State of Charge == Capacity.

   51       A value to compensate readings for various battery chemistries and operating temperatures.
   52       max17040,41 have 2 byte rcomp, default to 0x97 0x00.
