Upon visual inspection it appears that a thermal event occurred.It is not possible to determine the exact sequence of events that led to the thermal event.However, there is evidence that a short circuit occurred in the lower battery pack between the cells and printed circuit board (pcb).There was a blackening on the top of the lower battery pack and its pcb.Cells 1,2, and 3 appear to have been involved in the thermal event, likely by supplying energy into a fault in the board.Additionally, there was a slight melting of the handset plastic enclosure.This concludes the investigation.Upon initial receipt of the complaint, aribex did not believe that the event was a reportable event.However, on 02/06/2017, an investigation determined the event to be reportable.A recall is ongoing.Reference recall z-2016/2017-2016.
