Cleaning your hearing aid device
If you are not using your hearing aid for an extended period of time, we advise you remove the battery. Removing the battery and replacing the tab will prevent air entering the cell, preserving battery life. When you aren't using the hearing aid, leaving the battery door open will allow it to dry out to prevent condensation forming and extend battery life.
If you own a hearing aid drier or dehumidifier, do not place your batteries in this, as they may get dried out, reducing battery life.
When you want to use your hearing aid device again, remove the tab once more and replace the battery as normal.
You should regularly clean your hearing aid - any dirt or debris can severely affect the performance of your device and its battery. Ensure your hands are clean when handling your device and battery.
Avoid bringing your hearing aid or batteries into contact with sprays, creams or oil, including sun cream, perfume or hairspray. These products may clog parts of your device.
Do not wear your hearing aid in wet environments, such as in the bath or shower. Similarly, your device may also be damaged of it is worn in swimming pools, steam rooms, saunas and other humid environments.
