One aspect of this disclosure relates to a system for dynamic battery management in implantable medical devices. An embodiment of the system includes two or more devices for measuring battery capacity for an implantable medical device battery. The embodiment also includes a controller connected to the measuring devices. The controller is adapted to combine the measurements from the measuring devices using a weighted average to determine battery capacity consumed. According to various embodiments, at least one of the measuring devices includes a coulometer. At least one of the measuring devices includes a capacity-by-voltage device, according to an embodiment. The system further includes a display in communication with the controller in various embodiments. The display is adapted to provide a depiction of battery longevity in units of time remaining in the life of the implantable medical device battery, according to various embodiments. Other aspects and embodiments are provided herein.

We claim: 1. A system, comprising:a first battery capacity measuring device configured to calculate battery capacity consumed during a first time period for an implantable medical device battery;a second battery capacity measuring device configured to calculate battery capacity consumed during a third time period for the implantable medical device battery;a controller connected to the measuring devices, the controller configured to determine a weighted average of the calculations from the first and second devices to determine battery capacity consumed during a second time period for the implantable medical device battery, wherein the weighted average varies linearly based on capacity consumed; andwherein the first time period begins at the beginning of life of the battery and ends at the beginning of the second time period, and the third time period begins at the end of the second time period and ends when the battery capacity expires.
