“What hearing aid battery kind should I buy?” is a hard question to answer generally, because there are many distinct models of hearing aids, and each takes a battery that matches it and contains adequate energy to operate it. The simplest situation to deal with is if you currently use a hearing aid; if that’s the case, look at the owner’s manual that came with it or contact the hearing care provider who sold it to you to identify the correct battery. If you are still looking for a hearing aid and attempting to choose which style is right for you, you might wish to do some comparison shopping to assist you in your decision. Different sizes of hearing aid batteries vary greatly in cost, and in the life of the battery, so your selection of hearing aid can affect how much money you spend in the long run using it.
The manufacturers of hearing aids and hearing aid batteries have made life simpler for you by implementing a standardized color coding system, to make finding the right size easier. Batteries of the same type and size will always have the identical color code on their packages, no matter who made them.
The most common ones are:
Size 10 / Yellow – Hearing aid batteries with a yellow color code are Size 10, and can be the easiest to obtain because they are typically used in Completely-In-Canal (CIC) and In-The-Canal (ITC) types of hearing aids; their battery lifespan is shorter, generally 80 hours.
Size 312 / Brown – Size 312 hearing aid batteries carry a brown color code, and are often used in In-The-Canal (ITC) and In-The-Ear (ITE) hearing aids; Size 312 batteries have a normal battery life of approximately 175 hours.
Size 13 / Orange – Orange corresponds to Size 13 hearing aid batteries. These batteries are intermediate in size and hold a charge for about 240 hours. This size battery is commonly found in In-the-Ear (ITE) and Behind-the-Ear (BTE) hearing aids.
Size 675 / Blue – A color code of blue always identifies Size 675 batteries, which are often found in larger Behind-The-Ear (BTE) style hearing aids and in cochlear implants; these batteries have a normal battery life of about 300 hours.
Some varieties of hearing aids call for different batteries, however that is uncommon. Getting alternative sizes can be a bit more difficult since many merchants do not stock or advertise them, but if you inquire they can be ordered for you.
Prior to stocking up on batteries, make sure to read the manual that was included with your device to be sure it doesn’t run on rechargeable batteries; if it does, you need disposable batteries only as back-up. To keep your batteries fresh and fully charged after you buy them, always store them inside at room temperature and in their original, unopened packages.
