The reported events of premature battery depletion and no output were confirmed.The device was received with no telemetry communication and no output due to battery at end of life (eol) level.The device was cut open to enable further testing and the battery was found depleted.Analysis performed after replacing external power supply found high current drain.Hybrid leakage test did not find any anomaly.Capacitor leakage test was performed, and high current was noted on a capacitor which showed the most likely cause of high current to be a capacitor anomaly.Assessment of total projected longevity was performed, and premature battery depletion was observed.
