“Which kind of hearing aid battery do I need?” is a difficult question to answer generally, because there are numerous different types of hearing aids, and each needs a battery that matches it and offers enough energy to power it. For anybody that currently owns a hearing aid the owner’s manual should clearly indicate which battery is required. Conversely you may call the professional that sold you the device to ask. If you’re still shopping for a hearing aid and attempting to choose which model is right for you, you might wish to do some research to assist you in your selection. The explanation for this is that hearing aid batteries vary in price and in battery life, and so a rough knowledge of how many batteries you will need over time may influence your choice of which hearing aid to get.
The makers of hearing aids and hearing aid batteries have made things simpler for you by coming up with a standardized color coding system, to help make finding the right size easier. Regardless of who the maker is, hearing aid batteries of a specific type and size will always have the identical color code on their packages.
The 4 most common varieties are:
Size 13 batteries are generally used in Behind-the-Ear (BTE) and In-the-Ear (ITE) hearing aids, and have an expected battery life of 240 hours.
Hearing aid batteries with a color code of yellow are Size 10, and can be the easiest to obtain because they are widely used in Completely-In-Canal (CIC) and In-The-Canal (ITC) models of hearing aids; their battery lifespan is shorter, an average of 80 hours.
A color code of brown corresponds to a Size 312 battery, generally used in In-The-Canal (ITC) and In-The-Ear (ITE) styles of hearing aids; due to their smaller size they typically have battery life near 175 hours.
Size 675 is coded blue, and is frequently used in Behind-The-Ear (BTE) hearing aids and in some cochlear implants; these batteries are comparatively large and have the benefit of a long charge – up to 300 hours.
These are the most widespread sizes of hearing aid batteries, however there are hearing aids that require different ones. If yours requires one of these alternate types, most retailers that sell batteries can custom order them for you.
Don’t forget to consult the manual that comes with your device before purchasing batteries, because a number of the new hearing aids take rechargeable batteries, so disposable batteries are only needed for emergencies. To keep your batteries fully charged after you buy them, always store them in the original unopened packages at room temperature.
