Q / X Series Battery & Bottom Moulding 

Compatible with X Series handsets V6.0 or newer. 

NOTE:

Your handset battery will come pre fitted to the back of a handset. All you will need to do is attach the white connector to the two prongs on the PCB. Making sure that the two silver dots on the white connector are facing you. 

Putting it the other way will damage the battery and your handset.
