Description: 

Please NOTE: We improved this item by adding a clear plastic dielectric piece in the unit since Nov.7th 2015, which ensures all batteries protected from short circuit and accidental activation. 
Therefore, please open the battery cover and remove this little plastic dielectric piece under the battery before using(See the 6th picture for reference). Or the unit may not work. But it's also possible that you received our old version without such clear plastic dielectric piece. In this situation, the battery is packed in a separate bag which you need to put it in the computer yourself.
