sbs-battery.c: Capacity attr = remaining relative capacity
Currently, the capacity exported by this driver refers to reg 0x0e, which is the absolute state of charge which according to SBS refers to the design capacity/ energy of the battery. It can be > 100 % and drops below 100 % for a fully charged battery with the battery aging. This is not what the user exspects of a remaining capacity indication between 0 and 100 % with 100 % referring to a fully charged battery. This is provided by SBS reg 0x0d, which is the relative state of charge referring to the full charge capacity.
