according to ACPI spec the "Power Unit" of _BIF (Battery Information) object can be: 0x00000000 – Capacity information is reported in [mWh] and charge/ discharge rate information in [mW]. 0x00000001 – Capacity information is reported in [mAh] and charge/ discharge rate information in [mA]. The kernel ACPI battery driver uses this information and exposes charge_battery_props (i.e. the CURRENT_NOW) or energy_battery_props (i.e. the POWER_NOW) according to value of "Power Unit".
