According to The Royal National Institute for Deaf People, there are in total 8,945,000 deaf and hard of hearing people in the UK. For many people, the recommended solution by their audiologist or GP is to use a type of micro-computer to enhance external sound, called a hearing aid.
These micro-computers run on batteries which are likely to last anywhere between 4 week to 6 weeks depending on the type and amplification of the device. Therefore, if you are able to extend their use, you will be saving thousands of pounds over the lifespan of the aid.
Tips To Prolong The Lifespan Of Your Hearing Aid Batteries:
1. Pay attention to their shelf life - This refers to the time an inactive battery can be stored before it becomes unusable. Make sure that the battery which you have bought is still within its calendar life. If you purchase from a reputable source, such as a busy high street or online seller, their rapid turnover will almost guarantee that only new stock goes on the shelves.
2. Be sensible - When the device is not in use, switch it off. There are certain activities where you should not wear a hearing aid, such as sleeping, swimming, bathing etc. By switching off the device, you will greatly extend the battery's life. You will also likely to prevent damaging the device due to excessive moisture.
3. Avoid exposing the device to extreme conditions - Certain temperatures, either too hot or too cold might expedite the depletion of the battery. Keep the device indoors when it is not in use at room temperature.
4. Use dedicated hearing aid batteries - There are number of hearing aid batteries manufacturers such as Rayovac whose batteries are designed for hearing aids, and for optimising performance and longevity.
5. Minimise use of extra settings - To maximise battery life, only use the settings you really need. Limit the times you switch between settings and only use the settings you were recommended to use.
Despite your best attempts, the battery might lose power when you need it the most. It is therefore recommended to always carry extra hearing aid batteries with you to avoid losing your hearing at critical times.
