Batteries

Important battery information:

There are many factors that affect how long a hearing aid battery lasts:

An individual’s hearing loss – As severity increases:

• Increased amplification is required
• Increasing current
• Reducing battery life

2. The battery size – As the physical size of the batteries decrease, the amount of ingredients needed o power the battery also decreases, making the battery life shorter for smaller batteries and longer for bigger batteries.

3. An individual’s hearing aid usage – Two things to take into account:

• How many days a week do you wear your hearing aid?
• How many hours a day do you wear your hearing aid?

4. Instrument Differences – Sophisticated features such as noise cancellation and multi-channel processing may reduce battery life by up to 20%. Wireless and Bluetooth features when in use can increase the current up to 300% further reducing battery life.

5. Environment – Low & High humidity can affect the battery in different ways.

Low Humidity:

• Batteries may dry out, reducing the battery life.
• Drying out may be occur if users are indoors during the winter months in northern climates & if wood buring appliances are used to heat the home. Keeping the battery in dry aid kits in an already dry environment & using the hearing device intermittently may also cause the battery to dry out.

High Humidity:

• Batteries may take on moisture, interfering with the natural discharge expansion, resulting in swelling/leakage and reducing battery life.
• Your batteries may take on moisture if you work outdoors for extended periods in high temperature/high humidity areas or you live in a non air conditioned environment in high humidity areas

6. Temperature

As temperature is reduced:

• Hearing aid battery voltage is lowered and reaches functional end point earlier, reducing battery life.
• Thic can be an issue if individuals are working outside in the winter or in a refrigerated environment.

7. Altitude

As altitude increases:

• Percentage of oxygen level in the air is reduced, lowering the hearing aid battery voltage, causing the battery to reach the endpoint earlier and reduces battery life.
• This can be an issue if individuals live in areas at high altitude or travel by plane when battery is in late discharge.
