Purchasing hearing aids is not just about acquiring a product; it involves a series of operations, usage, and maintenance considerations. That's why we often say that the day the fitting is completed marks the beginning of wearing hearing aids.
The small details, tips, and subtle precautions in using hearing aids often play a decisive role in adapting to them. Today, let's explore the common issues with rechargeable hearing aids!
Charging the Hearing Aid Charging Case with a Fast Charger for Smartphones?
No, using a fast charger for smartphones can easily damage the charging case and the hearing aids. Please use the official dedicated charging case and charging cable for charging.
Hearing Aid Making Whistling Sounds in the Charging Case?
Possible reasons include: when the charging case is out of power, placing the hearing aids in a closed space while they are not turned off may cause whistling. Press and hold for 5 seconds to turn off if the hearing aids are not in the induction area or placed incorrectly in the charging case.
After not using the hearing aids, should they be placed in the charging case or a drying box?
It is recommended to place them in the charging case after removal to keep the hearing aids ready at all times. If the weather is humid, they can be placed in a physical drying box for dehumidification. After drying, place them back in the charging case.
Does continuous charging of the hearing aids affect their lifespan?
After removing the hearing aids, they can be continuously charged in the charging case without significantly affecting their lifespan.
Can they be placed in an electronic drying box for dehumidification?
It is not recommended to put them in an electronic drying box for dehumidification because:
- The rechargeable hearing aids are made using integral molding technology, with a fully sealed design, making them less prone to moisture.
- The optimal temperature for lithium batteries is between 15°C and 35°C, while electronic drying boxes can generate temperatures exceeding 50°C during drying, potentially affecting the lifespan of lithium batteries. Therefore, it is not advisable to put rechargeable hearing aids in electronic drying boxes for dehumidification.
Can a vacuum maintenance device be used for dehumidification?
It is not recommended because the working principle of the vacuum dehumidification maintenance device for hearing aids is to create a vacuum in the container through a vacuum pump, achieving the dehumidification of the hearing aids. The hearing aids are in a negative pressure state in the vacuum dehumidification maintenance device, which imposes high requirements on the sealing of lithium batteries. There is a risk of expansion or overflow of liquid inside the lithium batteries, potentially damaging the hearing aids.
