Abstract
Systems and methods for estimating a state of charge of a hearing aid rechargeable battery for rapid user feedback and charge management are provided. The method includes detecting a rechargeable battery of a hearing aid received at a battery charger. The method includes retrieving a last state of charge (SoC) of the rechargeable battery and a time in use of the rechargeable battery. The time in use is a time the hearing aid is out of the battery charger. The method includes estimating a current state of charge (SoC) of the rechargeable battery based on the last SoC and the time in use of the rechargeable battery. The method includes causing a display of the battery charger to present the estimated current SoC.
