Additional Manufacturer Narrative
Product event summary: the device was returned and analyzed.The returned device indicated shorting/low impedance in the battery.Hybrid analysis revealed that the device loss of telemetry and all functions were due to a severely depleted battery.The device was fully functional and operated under normal current drain when powered with an external supply.There was no evidence of a high current drain condition, and no hybrid anomalies were observed.Battery analysis revealed that lithium plating was found to initiate from the case, extended under the head space insulator (hsi) and contacted the cathode tab.The tab is located in segment 3 of the coil.Based on this analysis, the premature battery depletion was the result of an internal short from the plated lithium material bridging the case (negative polarity) and cathode tab (positive polarity).If information is provided in the future, a supplemental report will be issued.
