Choosing a Hearing Battery

There are many different types of hearing aids on the market today. Likewise there are also many different hearing batteries on the market. Unfortunately one hearing battery may not be nearly as good as another battery. So people must choose which type of battery they need and which type of battery is best for them.

It can sometimes be tough to know which hearing battery goes with which hearing aid. Luckily most of the batteries are color coded. (see above)

Once a person discovers which colored hearing battery is needed, then the person should consider how long each brand of hearing battery lasts. For the most part each battery should last one to two months. The life of the battery is determined by the brand and by how much or how little a hearing aid does.

Of all the types of hearing aids, BTE or Behind the Ear microphones, are probably the best to use. This is because Behind the Ear microphones allow the user to know where the sound is coming from. Just like we have two ears so we know where a sound originates, BTE microphones allows the hearing aid user to know where the sound is coming from. Of course, a hearing aid like this would more quickly drain a hearing battery.

The amplifier also affects how long a hearing battery will last. The amplifier makes sound louder and they are classified in one of three categories. The categories are Class A, Class B, and Class D. The categories are based on output abilities, gain, and - what determines the life of the battery - power consumption.

The speaker in the hearing aid is another part that determines the life of the hearing battery. Of course the speaker is what transmits the sound from the outside to the person needing the hearing aid. With the new technology with hearing aid speakers many of them are very small and fit right into the ear. The hearing aids with this type of speakers are called RITE (Receiver-in-the-Ear) and they are not much more expensive than other hearing aids with other speakers. They also don't consume any more of the battery.

People who need to buy a hearing aid need to consider their wants and needs. Another thing they also must consider is the type of hearing battery the device takes. Often this factor is overlooked.

A hearing battery should be chosen based on price and how long the battery is supposed to last. People who wear a hearing aid should continue to test out different batteries until they find a hearing battery that is a good price and lasts a long time.
