Preserving the Life of your Hearing Aid Batteries
How long a hearing aid’s battery lasts depends on several factors, first of which is the battery size. Small discreet hearing aids require a smaller battery with a shorter expected life. The smallest is size 10, which with typical use will last between 3-4 days. On the other hand, a large loss of hearing will require a more powerful hearing aid, and therefore a larger battery is required, with size 13 batteries lasting 12-14 days and size 675 batteries used in superpower hearing aids lasting 3-4 weeks. The most common size, a 312 battery, lasts around 7-9 days.
It is important to keep in mind that hearing aids are miniaturized computers making thousands of calculations every second, and then amplifying the processed sound into the ear. The more advanced features that are activated, such as wireless connectivity, the faster the battery drain. A very steady voltage is required and so Zinc-Air batteries are used, which are very different than most other batteries used around the home. Once the sticker is removed from the battery, air enters the cell and activates the current producing process. The battery will then produce voltage for a limited time, regardless of how many hours of use which is why occasional use to save battery life is often futile! Environmental factors can also reduce battery life, such as very low or very high humidity, very cold conditions, and high altitude. We recommend you keep them in a cool dry place such as a desk drawer or bedside cabinet.
Sustainability - Recycling
At Bay Audiology, we are proud to operate our Battery Recycling Programme. Hearing aid batteries contain chemicals and heavy metals which can be environmentally hazardous, so it is important to dispose of them appropriately. It's free to join and the programme is available at all of our clinics.
How does the Battery Recycling Programme Work?
We will provide you with a hearing aid battery recycling box, which holds approximately 70 - 80 hearing aid batteries, and is provided FREE of charge to all hearing aid wearers. You do not have to be a Bay Audiology client to take part in the recycling programme.
Simply fill the box with your old hearing aid batteries, and drop it into your local Bay Audiology clinic.
So how do I start?
Pick up your recycling box from your local Bay Audiology. There is no cost to join our hearing aid battery recycling programme.
We are genuinely committed to ensuring that every used hearing aid battery gets recycled and does not end up in one of our lakes or streams. Please help us to help the environment.
