Systems and methods used to reserve a constant battery capacity
First Claim
1. A therapeutic medical device comprising:
- a housing;
electronic circuitry disposed in said housing and configured to generate a signal used in a therapeutic regimen;
a battery disposed within said housing and providing energy to said electronic circuitry for generating said signal; and
a battery control system operable to maintain a substantially constant reserve capacity throughout the life of said battery.

Abstract
Techniques are disclosed which provide a substantially constant battery reserve capacity with respect to therapeutic medical devices. Accordingly, a battery control system may be operable to maintain a substantially constant reserve capacity throughout the life of the battery. The battery reserve capacity activation threshold may be set and continuously or periodically updated so that a battery'"'"'s remaining capacity equals the predetermined reserve capacity when the measured parameter reaches the activation threshold, thereby allowing a maximum amount of a battery'"'"'s total capacity to be employed for therapeutic use and reserve only that portion of that capacity determined to provide for a desired level and/or period of device function after reaching the reserve threshold.
