Abstract: A rechargeable hearing aid including an internal power unit such as a lithium ion battery having a short recharging time and a portable hearing aid charging and protection system for charging it. The charging system includes a protection system to prevent overheating and overcharging of the battery, an interface apparatus such as a Micro-USB connector, an induction charging device, a wireless induction charging device, or other suitable charging system interface apparatus to uniquely couple a charging power source, the charging and protection system and the internal power unit together. Among other features, the charging system communicates with the hearing aid to protect it by automatically turning off the hearing aid power while charging the hearing aid battery, turning the hearing aid power back on when charging is complete, and stepping the normal output voltage of the power unit down to the much lower operating voltage of the hearing aid.
