1. A method of adjusting a charge strength indicator for an implanted medical device, comprising:
- transcutaneously transmitting electrical energy to charge the implanted medical device;
detecting an electrical parameter; and
adjusting a threshold at which the charge strength indicator generates a user-discernible signal based on the detected electrical parameter.

Abstract
Electrical energy is transmitted to charge the implanted medical device, and an electrical parameter (e.g., a steady-state voltage) indicating a rate at which the implanted medical device is charged by the electrical energy is detected. A threshold (e.g., by modifying a stored threshold value) at which the charge strength indicator generates a user-discernible signal is adjusted based on the detected electrical parameter.
