ABSTRACT:
A battery monitoring system monitors status of a battery in an implantable medical device by comparing a measured battery status trend to a calculated battery status trend. The measured battery status trend is a trend of measured parameter values each indicative of an actual state of depletion of the battery. The calculated battery status trend is a trend of calculated parameter values each indicative of an expected state of depletion of the battery.
