Manufacturer Narrative
|
An investigation was performed by product engineering to assess the reported issue.Due to the hazardous condition of the failed battery and the shipping restrictions for damaged/defective lithium batteries, the device could not be returned for a detailed failure analysis from philips or the supplier.However, evidence reviewed by philips electrical engineering confirmed the battery underwent thermal runaway.Thermal runaway is an extremely rare event caused by several possible flaws within a cell which causes a reaction that spreads to the other cells in the battery.When this unavoidable issue does occur, the battery is contained in a metal enclosure behind a plastic shroud that protects patients and users from contact with the failed battery.
