Systems and techniques that enable a user to selectively extend the time prior to providing an indication of power source depletion, e.g., allow an extended the recommended replacement time (RRT) prior to providing an elective replacement indication (ERI), are described. The user provides input, which may indicate an acceptable level of implantable medical device performance, e.g., that lesser performance for a period between a default RRT and an extended RRT is acceptable. In response to the input, the time until providing an RRT/ERI notification, or some other indication of depletion of the implantable medical device power source, may be extended.

The implantable medical device system of claim 1, wherein the default time comprises a default recommended replacement time for the implantable medical device and the extended time comprises an extended recommended replacement time for the implantable medical device, wherein the extended recommended replacement time is later than the default recommended replacement time. 5. The implantable medical device system of claim 1, wherein the prompt indicates a future level of performance of the implantable medical device with respect to the performance characteristic. 6. The implantable medical device system of claim 1, wherein the prompt prompts the user to select a level of performance of the implantable medical device with respect to the performance characteristic, and the user input comprises a selected level of performance. 7. The implantable medical device system of claim 1, wherein the implantable medical device comprises at least one processor of the one or more processors. 8. The implantable medical device system of claim 1, further comprising an external user interface device that is configured to communicate with the implantable medical device and comprises at least one processor of the one or more processors. 9. A non-transitory computer-readable storage medium comprising instructions that cause one or more programmable processors to: determine a default time to provide an indication of depletion of a power source based on a default level of performance of an implantable medical device with respect to a performance characteristic of the implantable medical device, wherein the performance characteristic of the implantable medical device changes as the power source of the implantable medical device is consumed over time;provide a prompt to a user for user input that indicates an acceptable level of performance of an implantable medical device with respect to a performance characteristic of the implantable medical device;receive the user input, wherein the user input indicates that the acceptable level of performance of the implantable medical device with respect to the performance characteristic is lower than the default level of performance of the implantable medical device with respect to the performance characteristic;determine an extended time to provide the indication of depletion of the power source based on the user input, wherein the extended time comprises a future time when the performance characteristic of the implantable medical device no longer meets or exceeds the user-indicated acceptable level of performance, and wherein the extended time is later than the default time to provide the indication;monitor the level of the performance characteristic of the implantable medical device; andprovide the indication of depletion of the power source at the extended time, wherein the prompt prompts the user to select the extended time to provide the indication of depletion of the power source in response to reaching the default time to provide the indication of depletion of the power source. 10. The non-transitory computer-readable storage medium of claim 9, wherein the performance characteristic of the implantable medical device comprises a charge time of a discharge capacitor of the implantable medical device. 11.
