This extra moisture might block your device's air vent, making it less efficient. Moisture can also interact with the chemicals in the battery, causing it to degrade more quickly. Here are some precautions you may take to avoid moisture-induced battery drain: Before storing the hearing aids, open the battery door. This will remove any excess moisture that may have accumulated inside the case.
If the batteries show signs of corrosion or other damage, don't use them until they have been replaced by a qualified professional. Corrosion within the battery casing can lead to internal short circuits that could cause injury if not detected by regular inspection of hearing aid batteries.
Batteries lose their capacity over time, but this loss is much greater for rechargeable batteries than primary batteries. Primary batteries cannot be recharged; they must be replaced once they reach end of life. Rechargeable batteries can be replaced at any time without damaging the device, but they should never be used after their expiration date. This limit varies by model, but generally ranges from one year for small, inexpensive devices to three years for larger, more expensive models. Replacement of rechargeable batteries before their expiration date prevents them from being damaged or destroyed while still providing enough energy to operate the device.
Hearing aid batteries are essential to maintaining your assistive listening devices. Without these batteries, you would be unable to listen to music or conversations with the touch of a button.
Unused batteries should be stored in a cool, dry area. Extreme heat and dampness can also limit their lifetime. Use only clean hands. Before changing the battery, wash your hands since oil and grime might harm the hearing aid. Do not use cotton balls or similar items as these could become flammable if soaked with fuel or alcohol.
The best way to protect your hearing aids is not to wear them. Hearing loss due to aging affects many people in the United States. Some studies show that almost half of all Americans over the age of 60 suffer from some degree of hearing loss. Hearing aids are very effective at restoring sound perception to those who have hearing problems. However, they cannot restore sound perception to those who want it gone. If you are facing hearing loss, talk with your doctor about whether hearing aids are right for you. He or she will be able to help you decide what type of hearing aid is best for your situation.
