Abstract
Processing circuitry associated with an implantable medical device (IMD) may store a value of a shared voltage as a battery voltage threshold. A shared voltage is a voltage magnitude at which the voltage curves for the population of batteries converge at a particular percent depth of discharge (% DoD). The shared voltage is a consistent voltage magnitude across the population of batteries. Based on the indication that the battery has reached the shared voltage, the processing circuitry may determine any or all of: the battery % DoD level, the amount, e.g., the percent of electrical energy remaining in the battery and the amount of time remaining before the battery reaches its end of service life. In some examples, the processing circuitry may output an elective replacement indicator based on the calculated amount of time remaining before the battery reaches its end of service life.
