“What kind of hearing aid battery will I need?” is a hard question give a single answer to, because there are numerous different types of hearing aids, and each requires a battery that matches it and provides enough energy to operate it. If you already have a hearing aid, consult that device’s owners manual or the hearing care professionals who sold it to you to identify the proper battery type and size. If you don’t wear a hearing aid yet and are trying to decide which type and model is right for you, do a little research to help you decide. Different sizes of hearing aid batteries vary greatly in cost, and in the life of the battery, so your selection of hearing aid will affect the amount of money you spend over time using it.
The makers of hearing aids and hearing aid batteries have made things simpler for you by implementing a standardized color coding system, to make locating the correct size easier. Irrespective of who the manufacturer is, hearing aid batteries of a specific type and size will always have the same color code on their packages.
The main battery types to be aware of are:
Orange (#13) – Batteries with a color code of orange are Size 13, and fit In-the-Ear (ITE) and Behind-the-Ear (BTE) types of hearing aids; their battery life is considered to be up to 240 hours.
Brown (#312) – The color brown corresponds to Size 312 batteries. Size 312 batteries are on the smaller side and normally hold a charge for around 175 hours. Size 312 batteries are common in In-The-Canal (ITC) and In-The-Ear (ITE) hearing aids.
Yellow (#10) – The color yellow always means Size 10 batteries. Size 10 are the smallest and most plentiful size of hearing aid battery with a normal battery life of 80 hours. Size 10 batteries are standard in In-The-Canal (ITC) and Completely-In-Canal (CIC) hearing aids.
Blue (#675) – Blue always means Size 675 batteries. These batteries are fairly large and can hold a long charge – up to three hundred hours. Size 675 batteries are prevalent in larger Behind-the-Ear (BTE) hearing aids and in cochlear implants.
Some kinds of hearing aids demand alternative battery sizes and types, but these are the most common. If yours need one of these alternate types, most merchants that sell batteries can custom order them for you.
Don’t forget to consult the manual that comes with your unit before buying batteries, because some of the new hearing aids take rechargeable batteries, so you need disposable batteries only as a backup in the event of emergencies. Furthermore, always store your hearing aid batteries in their unopened packages and at room temperature to make sure that they hold their full charge.
