13. A method for determining a time remaining to a recommended replacement time of a battery of an implantable cardiac stimulating device, comprising the steps of:
-
monitoring device operating and battery parameters from the stimulating device; determining a first amount of battery charge actually depleted as a function of the battery parameters, the battery parameters including battery voltage, battery current drain, and internal battery impedance; determining a second amount of battery charge corresponding to a point in time at which the stimulating device is recommended for replacement; determining an amount of battery charge remaining to the recommended battery replacement time by subtracting the second amount of battery charge from the first amount of battery charge; and predicting the time remaining to the recommended battery replacement time based on the amount of battery charge remaining and the monitored device operating parameters. - View Dependent Claims (14, 15, 16, 17)
