    PRODUCT EVENT SUMMARY: THE BATTERY WAS RETURNED FOR EVALUATION. THE REPORTED EVENT COULD NOT BE CONFIRMED DURING TESTING. FAILURE ANALYSIS OF THE RETURNED DEVICE REVEALED THAT THE DEVICE PASSED VISUAL EXAMINATION AND FUNCTIONAL TESTING. THE BATTERY WAS ABLE TO ADEQUATELY PROVIDE POWER TO A TEST CONTROLLER. IN ADDITION, THE BATTERY WAS CHARGING WHEN CONNECTED TO A BATTERY CHARGER. A REVIEW OF THE BATTERY'S INTERNAL LOG REVEALED THAT A CELL PAIR, AT ONE POINT IN TIME, PASSED THE VOLTAGE THRESHOLD. WHEN THIS OCCURS, THE BATTERY WILL NOT CHARGE UNTIL THE VOLTAGE DECREASES BELOW THE THRESHOLD. HOWEVER, THE BATTERY WAS RECEIVED WITH NO FLAGS ENABLED. IF THE BATTERY REMAINS CONNECTED TO THE BATTERY CHARGER WITH A CELL-OVER-VOLTAGE FLAG, THE BATTERY CHARGER STATUS INDICATOR WILL FLASH RED AFTER 8 HOURS DUE TO A CHARGE TIME-OUT. AS A RESULT, THE REPORTED BATTERY NOT CHARGING WAS CONFIRMED. HOWEVER, THE REPORTED BATTERY NOT PROVIDING POWER COULD NOT BE CONFIRMED. BASED ON THE AVAILABLE INFORMATION, A POSSIBLE ROOT CAUSE OF THE BATTERY NOT CHARGING CAN BE ATTRIBUTED TO AN OVERVOLTAGE FAULT DETECTED BY THE ANALOG FRONT END (AFE) INTEGRATED CIRCUIT. BASED ON AN INTERNAL INVESTIGATION, BATTERIES WITH A CELL OVER VOLTAGE CONDITION CAN BE ATTRIBUTED TO BATTERY CHARGERS ASSEMBLED WITH INCORRECT INDUCTORS. MEDTRONIC, INC. (MEDTRONIC) IS SUBMITTING THIS REPORT TO COMPLY WITH 21 C.F.R. PART 803, THE MEDICAL DEVICE REPORTING REGULATION. THIS REPORT IS BASED UPON INFORMATION OBTAINED BY MEDTRONIC, WHICH THE COMPANY MAY NOT HAVE BEEN ABLE TO FULLY INVESTIGATE OR VERIFY PRIOR TO THE DATE THE REPORT WAS REQUIRED BY THE FDA. MEDTRONIC HAS MADE REASONABLE EFFORTS TO OBTAIN MORE COMPLETE INFORMATION IN THE TIME ALLOTTED AND HAS PROVIDED AS MUCH INFORMATION AS IS AVAILABLE TO THE COMPANY AS OF THE SUBMISSION DATE THIS REPORT. THIS REPORT DOES NOT CONSTITUTE AN ADMISSION OR A CONCLUSION BY FDA, MEDTRONIC, OR ITS EMPLOYEES THAT THE DEVICE, MEDTRONIC OR ITS EMPLOYEES CAUSED OR CONTRIBUTED TO THE EVENT DESCRIBED IN THE REPORT. IN PARTICULAR, THIS REPORT DOES NOT CONSTITUTE AN ADMISSION BY ANYONE THAT THE PRODUCT DESCRIBED IN THIS REPORT HAS ANY "DEFECTS" OR HAS "MALFUNCTIONED". THESE WORDS ARE INCLUDED IN THE FDA 3500A FORM AND ARE FIXED ITEMS FOR SELECTION CREATED BY THE FDA, TO CATEGORIZE THE TYPE OF EVENT SOLELY FOR THE PURPOSE OF REPORTING PURSUANT TO PART 803. MEDTRONIC OBJECTS TO THE USE OF THESE WORDS AND OTHERS LIKE IT BECAUSE OF THE LACK OF DEFINITION AND THE CONNOTATIONS IMPLIED BY THESE TERMS. THIS STATEMENT SHOULD BE INCLUDED WITH ANY INFORMATION OR REPORT DISCLOSED TO THE PUBLIC UNDER THE FREEDOM OF INFORMATION ACT. ANY REQUIRED FIELDS THAT ARE UNPOPULATED ARE BLANK BECAUSE THE INFORMATION IS CURRENTLY UNKNOWN OR UNAVAILABLE. A GOOD FAITH EFFORT WILL BE MADE TO OBTAIN THE APPLICABLE INFORMATION RELEVANT TO THE REPORT. IF INFORMATION IS PROVIDED IN THE FUTURE, A SUPPLEMENTAL REPORT WILL BE ISSUED.
