Given
You sure, capacity in mA? Then I don't know. But you can safely fallback and create your own attribute (just as in David's battery class, where every battery required to create its own attributes), plus create capacity_units attribute. So, user space will know your driver's specific units. > the lack of a constant voltage, how do you accurately convert between > the two?
