Features of a Hearing Aid Battery

Hearing aid batteries are a vital part of the hearing aid itself, since none of the electronic parts work without being powered by the battery. Many individuals who have a hearing aid will also buy a hearing aid battery tester so that they can know when the battery is beginning to run out of power and have other batteries on hand to replace it. The length of time that a hearing aid battery lasts depends on the type of hearing aid that is employed by the individual. The smaller hearing aids that fit into the ear canal, either completely or almost completely, have a shorter battery life since they can only contain a smaller battery inside of them.

How It Works and Other Features

Older styles of hearing aid batteries utilized mercury to obtain the energy to power the hearing aid. These batteries are much less effective than the newer zinc batteries that are more commonly used today. The zinc hearing aid batteries use zinc air, meaning that the batteries use the oxygen outside the battery to combine with the zinc to provide the reaction that powers the battery, giving it about twice the life of the mercury battery systems.

The zinc hearing aid batteries come with a color coded tab on them which not only tells what the size of the battery is, but also keeps the air out of the battery until it is time to use it. Once the tab is removed, the oxygen in the air is allowed into the battery and activates it, since the zinc and oxygen begin to combine. For this reason the tab should not be removed until the individual is ready to use the battery so that it is fresh and new from the beginning.

There are four common sizes of hearing aid batteries on the market today so that every size of hearing aid has a battery that fits it. The smallest size is color coded with yellow and it labeled a ten. The largest size is six hundred seventy five and is labeled in blue. The hearing aids that fit inside of the ear canal typically use the smaller sizes and the behind the ear devices will use the larger sized batteries. Using the larger sizes insures a longer life before having to change the battery since there is more room for the zinc inside of the battery. However, because they are more bulky, many individuals would rather have to change the battery more often and have a less noticeable hearing aid, than to wear a noticeable device for the battery life.

Choosing Batteries

Choosing hearing aid batteries is probably more important than you realize. You want to choose high quality batteries that are going to be durable and last, so that you can hear as much noise as possible, the closest thing to having your full hearing back. Rayovac hearing aid batteries are one great option, but there are various others as well.

The Duracell hearing aid batteries are also quite popular and will make a great choice. The most important thing is that you choose high quality battery for your hearing aid that is going to last. It is worth it to spend a bit more money if it means that you are going to be getting a higher quality hearing aid battery.

Maintenance

Besides choosing your hearing aid batteries, there are also a few other steps that you are going to want to be aware of. To properly maintain your hearing aid, you want to make sure more than anything that you adapt the volume on the hearing aid to the situation. Depending on where you are and what you are doing, you may have to turn your hearing aid down or up.

By keeping your hearing aid set on the right volume for the right situation, you will not be straining and your hearing aid will be kept in best condition. Keep in mind that certain hearing aids actually have automatic volume adjusters, and in this case you would not even have to worry about it.

Also besides dealing with hearing aid batteries you need to make sure that you make the proper allowances for the effects of fatigue. This is probably the next most important thing, second to keeping an eye on the hearing aid batteries. Wearing hearing instruments and hearing a greater range of sounds, after all, may tire you or make you irritable at first, and you need to realize that it may take a bit of time for you to adjust.
