Samsung change the temperature range in battery discharing state from (0 <=temp < 100) to (-20 <= temp < 70) from this year. That's why we have to change the battery_temperature_range structure value as soon as possible so that our reliability team check the battery. BUG=chrome-os-partner:25731 TEST=Boot on the pit / pi and then check the battery is working or not in the oven.
