A REVIEW OF DEVICE MEMORY REVEALED THAT THE DEVICE DECLARED ELECTIVE REPLACEMENT INDICATOR (ERI) AFTER EXPERIENCING TWO CONSECUTIVE CHARGE TIMES GREATER THAN THE EXTENDED MID-LIFE ERI CHARGE TIME LIMIT. THE OBSERVED RATE OF BATTERY USAGE WAS COMPARED TO THE EXPECTED RATE OF BATTERY USAGE; THE RESULTS INDICATED THAT THE MONITORING VOLTAGE WAS NORMAL. ALTHOUGH THE BATTERY ITSELF HAD NOT DEPLETED PREMATURELY, ERI WAS TRIGGERED EARLIER THAN EXPECTED BY EXTENDED CHARGE TIMES DUE TO A HIGHER-THAN-TYPICAL BUILD-UP OF INTERNAL BATTERY IMPEDANCE. THIS DEVICE IS INCLUDED IN THE MID-LIFE DISPLAY OF REPLACEMENT INDICATORS (NOVEMBER 27, 2007) ADVISORY POPULATION. THIS ISSUE IS DISCUSSED IN THE Q2 2010 PRODUCT PERFORMANCE REPORT.
