Batteries are perhaps one of the most important hearing aid accessories; without them, the hearing aid wouldn’t have any power.
Hearing aids come in many different sizes and styles and with different power needs. Larger hearing aids require larger batteries. Additionally, hearing aids for people with severe or profound hearing losses typically require more power and larger batteries.
There are five sizes of hearing aid batteries available on the market. The sizes from smallest to largest are; 5, 10, 312, 13 and 675. Size 5 hearing aid batteries are rarely used. The four most common hearing aid battery sizes are all smaller than the diameter of a dime:
- Size 10 – 5.8 mm wide by 3.6 mm high
- Size 312 – 7.9 mm wide by 3.6 mm high
- Size 13 – 7.9 mm wide by 5.4 mm high
- Size 675 – 11.6 mm wide by 5.4 mm high
Because size differences may be hard to notice and difficult to remember, battery packaging is color-coded so finding and purchasing the correct ones is easier.
- Size 5 batteries – red label
- Size 10 batteries – yellow label
- Size 312 batteries – brown label (most common in the U.S.)
- Size 13 batteries – orange label
- Size 675 batteries – blue label
Listening Tube – Listen to the hearing aid every day. Using a listening tube, you can listen to the hearing aids to be sure that they sound clear and not weak or scratchy. Your audiologist will teach you how to listen for intermittency and internal feedback.
Forced Air Blower (not a hair dryer) – Check for dirt and grime. Earmolds can be removed from the hearing aids and cleaned with a mild soap solution. Dry them carefully using a forced air blower (not a hair dryer!). Be sure they are dry before reattaching them to the hearing aids.
Hearing Aid Drying Container – This is important for proper function. A hearing aid drying container will help keep moisture from building up inside the hearing aids and will lengthen their life. Be sure to take the batteries out of the hearing aid before placing them in the storage containers.
Volume Limiting Earphones – ETY-Kids safe-listening earphones are engineered to limit sound output while maintaining sound quality. By controlling the earphones, it is not necessary to restrict the volume setting on the player and sound coming through ETY-Kids earphones will not exceed safe levels. The main reason listeners of all ages turn up the volume is to block out distracting background noise. ETY-Kids earphones seal the ears with close fit ear tips so volume levels stay safer. With an adequate seal plus the sound output-limiting of ETY-Kids earphones, parents are assured their kids are listening safely.
Tubing, Domes & Tips
Hearing Aid Tubing – All Behind The Ear (BTE) hearing aid tubes harden and should be changed at least every six months. Many people find it beneficial or necessary to change them more frequently. BTE hearing aids become uncomfortable and more difficult to wear as the tubes become progressively stiffer. Also, it is claimed the sound transmission through hearing aid tubes deteriorates as the tubes harden.
Hearing Aid Domes – A hearing aid dome is the small plastic bell-shaped piece at the end of the tube. This is the actual physical piece that is inserted in your ear. A proper fitting dome can make a huge difference in both comfort and quality while wearing your hearing aid.
Hearing Aid Tips – Soft and comfortable Eartips can be used on behind the ear hearing aids, in the ear hearing aids, and pocket hearing aids.
