| Hearing Answers: Batteries for Hearing Aids |
|
| Hearing Aid Batteries |
|
| All hearing aids have batteries. Just like hearing aids, batteries come in different sizes. Although their small size can make batteries difficult to handle, especially for seniors, you must take care to insert the batter properly into the hearing aid so that the positive and negative sides are facing in the right direction. |
|
| Hearing aid batteries can be used for 1 to 4 weeks depending on the size of the battery, the power of the hearing aid, the setting of the volume control and many other things. |
|
| All batteries now sold are the Zinc-Air type. These Zinc-Air batteries last longer than the older mercury batteries and are better for the environment. The paper tab glued to the battery prevents the battery from draining while it is being stored. These batteries can be stored for one to three years, as long as the paper tab is never removed. You need to remove the paper tab to use a zinc-air battery. By removing the paper tab, the battery is activated and will begin to drain. While putting the paper tab back on the battery when it's not in use may slow the drainage slightly, the battery eventually will drain completely. |
|
| You should store batteries in a cool, dry place. Do not refrigerate them as this may shorten the life of the battery. Hearing aid batteries are different then normal batteries in that they operate at full power until they are almost fully drained, and then they stop quite abruptly. They do not slowly get weaker and weaker like most other batteries. Because of this, a hearing aid user should own a battery tester and should always carry extra batteries.
If a hearing aid is not going to be worn for an extended period, the battery should be removed from the hearing aid to prevent corrosion. The battery should also be removed if the hearing aid accidently becomes wet.
Batteries may be purchased from your audiologist, drug stores, and even some national organizations. Some brands do last longer then others and it is important that the batteries you purchase are as fresh as possible. |

| Battery Sizes |
|
| Here are common battery sizes: |
|
 |
#675 The largest size battery. It is usually used in Behind-The-Ear hearing aids. It has the largest storage capacity of hearing aid batteries. |
|
|
#13 The most common size of battery used for In-The-Ear hearing aids. It has less storage capacity then the #675, but it is also a smaller battery. |
|
|
#312 A smaller battery often used for In-The-Canal size hearing aids. It is thinner then the #13 battery and has a shorter total lifetime. |
|
|
#10 One of the smallest sizes available and is used for the Completely-In-the-Canal size of hearing aids. They don't have much storage capacity, but the small size makes them ideal for the very small hearing aid sizes. |
|
|
#5 The smallest size battery currently available. It is not carried by some distributors. This battery is usually used when even a #10 battery is too large to be put into the hearing aid. |
|
|
| Battery Safety |
|
| All batteries are toxic and dangerous if swallowed. Keep all batteries (and hearing aids) away from children and pets. If anyone swallows a battery it is a medical emergency and the individual needs to see a physician immediately. |
