摘要:
The present subject matter includes systems and methods for detecting a new hearing aid battery and estimating hearing aid battery life by analyzing changes in battery voltage signatures during the hearing aid device booting process. The analysis may include analyzing a boot signature voltage drop occurring upon initial application of a higher load. The analysis may include analyzing a boot signature voltage slope occurring during sustained application of a higher load. The analysis may also include analyzing a boot signature voltage droop occurring throughout application of a lower load and application of a higher load.
