In the past few decades, hearing aids have become more efficient and compact. It means people with hearing impairment do not have to attach a massive device to their ears.
Instead, the designs could be superb-simple most of the time. As you can guess, many factors have contributed to this development.
For instance, newer microchips have helped cut down the size of hearing aids while improving essential features.
But none of these could have been possible if we did not have modern hearing aid batteries. We believe it is one thing people take for granted in a hearing aid.
However, if you need a hearing aid for yourself or your loved ones, you should know a thing or two about hearing aid batteries.
You will have to replace these batteries once in a while. And, as you can guess, there are many varieties in the market.
In this guide, we have explained the basic things you need to know about hearing aid batteries.
We will first look at the common types of hearing aid batteries out there.
Types of Hearing Aid Batteries
You can find two major types of batteries used in hearing aids in the market.
#1 Rechargeable Batteries
As you can guess, you can take this type of battery from the hearing and charge it when the battery level is low.
You can find these batteries, mostly Lithium-Ion, on some of the premium and semi-premium hearing aid options in the market.
Even though rechargeable batteries have been in the industry for a while, not many hearing aid manufacturers have started using them.
While there are so many advantages to this type of battery, the customer will have to charge them overnight.
As we indicated earlier, you will have to spend a considerably high amount for a hearing aid equipped with a rechargeable battery.
#2 Disposable Batteries
Disposable batteries are primarily found in entry-level and mid-range hearing aids in the market.
It is safe to say that a typical hearing aid you see from the crowd will be using disposable batteries.
As you can guess, these batteries are designed for one-time use. Once the hearing aid has used up all the battery power, you will have to dispose of the battery and get a new one.
In most cases, disposable batteries are made using an alloy of zinc and other components. In case you did not know, these batteries require the presence of air to work properly.
While these are the major types of hearing aid batteries, other classifications and subclassifications also exist. We will take a look at some of them.
Color Coding for Hearing Aid Batteries
The color codes attached to hearing aid batteries tell a lot about the product. You can understand where it fits the most and where you should mainly use the battery.
More importantly, the color code also indicates the average lifespan of the battery. We will talk about some of them.
You can find the following color codes on hearing aids:
Here is the thing, though. The color does not mean anything in the world of hearing aid batteries.
As opposed to that concept, hearing aid battery color codes are linked to the size of the battery.
However, since people may find it difficult to remember the size of the battery, color codes are used.
Different Sizes of Hearing Aid Batteries
Given below are some of the standard sizes of hearing aid batteries. The size also determines the lifespan of the battery.
- Size 10 batteries are denoted by the color Yellow, and you can find them in mini RICs, CICs, and IICs.
- Size 312 batteries are denoted by the color Brown, and they are found in mini BTEs, RICs, and ITCs.
- Size 13 batteries are denoted by the color Orange, and you can find them in BTEs and ITEs.
- Size 675 batteries are denoted by the color Blue, and they are primarily used in Power BTEs.
Depending on the hearing aid you are getting — RIC, CIC, IIC, BTEs, ITCS, ITEs, or Power BTEs —, you would need a different type of hearing aid battery.
How Long Do Hearing Aid Batteries Last?
Of course, the answer depends on the hearing aid battery you are using.
If you are using a rechargeable hearing aid battery, you will have to recharge the battery every day or once a week. In most cases, these hearing aids are designed for full-day use.
So, when the user goes to sleep at night, they can put the hearing aid in the charging case, and it will recharge the battery.
You can find it quite similar to modern wireless Bluetooth earbuds.
Things are a bit different in the case of the disposal of hearing aid batteries. The lifespan of the battery is based on the type of the cell.
Therefore, all the battery types we have mentioned above have different lifespans. The major ones are:
- Size 10 batteries can last anywhere between three to seven days, requiring weekly replacement.
- Size 13 batteries can last between six to 14 days, requiring fortnightly replacement.
- Size 312 batteries can last between three to ten days, lasting a little more than a week.
- Size 675 batteries are the biggest in that they can last for nine to twenty days, requiring replacement once in three weeks.
As you can see, if you do not want to replace the batteries too often, you should get a hearing aid that uses the size 675 type of batteries.
Since they can last almost three weeks, a good supply of batteries should help you throughout a year.
The best way to figure out the right time for replacement is to listen to the sound quality.
If you feel the sound is getting distorted and unclear day by day, you will have to replace the hearing aid battery.
But there are always some methods to increase the lifespan. For instance, turning off the hearing aid when not in use can improve the battery life by a long shot.
We hope you got the basic ideas about hearing aid batteries from this article.
Considering that you have to choose between multiple options, make sure you prioritize the factors important to you, including the size and lifespan.
