Abstract
Methods, devices and program products are provided for determining an early battery depletion condition for a battery powered device. The method determines a charge consumption drawn externally from a battery cell by the device for a select period of time, obtains a measured cell voltage for the battery cell of the medical device, calculates a projected cell voltage based on the charge consumption and usage conditions, and declares an early depletion condition based on a relation between the measured and projected cell voltages.
