Battery driver also can use this attribute just to inform userspace

about maximal and minimal voltage thresholds of a given battery.



VOLTAGE_MAX, VOLTAGE_MIN - same as _DESIGN voltage values except that

these ones should be used if hardware could only guess (measure and

retain) the thresholds of a given power supply.



CHARGE_FULL_DESIGN, CHARGE_EMPTY_DESIGN - design charge values, when

battery considered full/empty.
