1. A method comprising:

  • measuring a battery terminal voltage of a battery of an implantable medical device;

    measuring a charge delivered by the battery during a first time period after the device has been implanted and before the battery terminal voltage falls below a first voltage threshold, wherein the first voltage threshold is a function of a measured rate at which the charge is delivered by the battery;

    calculating an available or depleted battery charge using the measured charge delivered by the battery during the first time period;

    communicating to a user an indication of the available or depleted battery charge; and

    communicating to the user an indication of whether the battery terminal voltage has fallen below the first voltage threshold.
