What Hearing Aid Battery Type Do I Buy?
It is difficult to give a definitive answer to the question “What type of battery should I buy for my hearing aid?” because hearing aid types and styles are so different, and so are the batteries that they use to power them. If you already own a hearing aid, review the device’s owners manual or the hearing care professionals who sold it to you to determine the right battery type and size. For anyone shopping for a first hearing aid you will be able to discover a lot with a little bit of comparison research. The reason behind this is that hearing aid batteries differ in price and in battery lifespan, and so a rough knowledge of how many of them you’ll need over time can affect your choice of which hearing aid to get.
The producers of hearing aids and hearing aid batteries have made life simpler for you by implementing a standardized system of color coding, to help make locating the proper size easier. No matter who the maker is, hearing aid batteries of a certain size and type will always have the same color code on their packages.
In all likelihood your hearing aid will use one of the following:
Orange (#13) – The color orange always means Size 13 hearing aid batteries. Size 13 batteries are intermediate in size and hold a charge for approximately 240 hours. Size 13 batteries are commonly found in Behind-the-Ear (BTE) and In-the-Ear (ITE) hearing aids.
Yellow (#10) – Batteries that have a color code of yellow are Size 10, and may be the easiest to locate because they are commonly used in In-The-Canal (ITC) and Completely-In-Canal (CIC) types of hearing aids; their battery lifespan is shorter, approximately 80 hours.
Brown (#312) – A color code of brown corresponds to a Size 312 battery, commonly used in In-The-Ear (ITE) and In-The-Canal (ITC) styles of hearing aids; because of their smaller size they generally have battery life of 175 hours.
Blue (#675) – The blue color code always identifies Size 675 batteries, which are generally used in larger Behind-The-Ear (BTE) style hearing aids or in cochlear implants; the 675 batteries have an average life of 300 hours.
These 4 battery types cover most hearing aids, but there are some exceptions that necessitate alternative batteries. If your device need one of these different types, most merchants that provide batteries can custom order them for you.
Be sure you read the owner’s manual that comes with your hearing aid before buying batteries, because some of the contemporary hearing aids have rechargeable batteries, so you need disposable batteries only as a backup in the event of emergencies. To keep your batteries fully charged after you purchase them, always store them in the original unopened packages at room temperature.
