Different Types Of Hearing Aid Batteries

Hearing aids are designed to amplify the sound which hearing impaired are unable to hear otherwise. Hearing aids can be analog as well as digital, although now more and more people are shifting towards digital aids. These come with microprocessors or electronic chips that work to increase the quality of the sound amplified.

The types of batteries used in a number of hearing aids will also make the difference, since better the battery installed, better will the quality of output. Here are a few standard battery types which are used in common hearing aids.

The size 675 which has a blue color code, with dimensions 11.6mm x 5.4mm, powers mostly behind the ear (BTE) hearing aids.

The size 13 which has an orange color code, with dimensions 7.9mm x 5.4mm, generally used for behind the ear (BTE) and in the ear (ITE) aids. The average life of this battery is between 6–14 days, again depending on the use.

The size 312 battery is brown color coded, with dimensions 7.9mm x 3.6mm, used for mostly mini behind the ear (BTE), receiver in the ear (RITE), and in the canal (ITC) hearing aids with an average battery life of 3–10 days.

The size 10 battery which is yellow color coded, with dimensions 5.8mm x 3.6mm, is generally used for mini receiver in the ear aids and completely in canal hearing aids.

There are a number of easy ways to extend battery life, for example, proper storage under normal temperatures. Batteries tend to deteriorate if stored under extreme heat or cold weather. Switching off the hearing when not in use is the easiest way to save battery life. Batteries should not come in contact with any other metal object like keys or gem clips in your purse which can short circuit it and cause damage to the hearing aid as well.
