Hearing aid battery
All Hearing aids button cell air batteries except body-worn aids.
In order to fully utilize the performance of the air battery, the following points should be noted when using the air battery.
Winter battery use precautions
The use of carbon dioxide generated by heating equipment can degrade the battery electrolyte and fail to perform its original performance. Therefore, in a room where heating or a large number of people are used, the battery life is likely to be shortened. When the temperature is too low and the battery temperature drops, it will also affect the operation of the power. When using the heater in winter, keep the room ventilated. When the battery temperature is too low, please use the body temperature for a little warmth before using.
Battery life as indicated in the catalogue and instruction manual
The battery life indicated in the catalogue and the instruction manual is the value of the continuous use of the hearing aid under normal conditions. The actual battery life will vary depending on the user's hearing settings and the environment in which they are used.
Precautions for hearing aid failur
When the hearing aid is suddenly silent, the problem may not be the battery, but the hearing aid malfunctions. When the battery is exhausted in one or two days or in a very short time when uses, please go to the hearing aid center for further testing.
