At Bryce Hearing Services we provide hearing aid batteries in sizes – 10, 312 & 13.
All batteries are priced at £2.50 for 1 packet of 6 batteries.
A box of 10 packets, containing 6 batteries each, is priced at £20.
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.
- 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.
- 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
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.
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.
