ABSTRACT:
A system and method monitors or reports the battery status of an implantable medical device to a user. The battery terminal voltage and charge delivered are measured. Before the battery terminal voltage falls below an Elective Replacement Indicator (ERI) threshold voltage, a charge-delivered indication of battery status is provided to a user. Thereafter, a battery terminal voltage indication of battery status is provided to a user. The Elective Replacement Indicator (ERI) and End of Life (EOL) threshold voltages are each functions of delivered battery current. A fault current detection is also provided to a user. A device temperature sensor discounts the battery voltage reading when the device is too cold.
