Batteries are the main source of power for small or portable equipments which needs to move a lot dynamically and hearing aids are one of them. Because you can not plug your ear device at a fixed power source all the time and use. You may need to use it while walking, at the market, at home, in a car, train or airplane, etc. Therefore battery plays a very important role in maintaining the hearing aid life expectancy.
The life prospect of a hearing aid battery mainly depends on its –
- Hearing aid battery capacity
- How much the machine drains the battery?
- For how long the hearing aid is worn?
For increasing the lifespan of hearing aids at full potential, you need to understand your hearing machine parts and components. Among all the components or accessories that keep your listening device in the best condition, ear machine battery is the essential purchase for hearing aid users. This is the main requirement of any of the equipment because without a battery they are nothing but an earplug.
But now the question arises that how to choose the right hearing aids batteries? because they come in various types, sizes, and capacities. Also, they have color codes according to their category. Hence, To find the right compatible batteries for your hearing aids, you need to know the hearing aid battery types, size, battery life, brands, and this list goes on.
Everything You Need to Know About Hearing Aids Batteries
Which batteries are compatible with my hearing aids?
It is not compulsory that every button cell battery type meets the criteria for your given hearing machine. Because of their different sizes, capacity, and lifespan various hearing aids need specific batteries for them. Therefore, these listening devices manufacturers have produced various types of hearing aids batteries depending on the need of their wearers.
Hence to find which battery is compatible with your hearing aid? you must know about all the required sizes of the battery that your ear machine accepts. Because due to its compact size every listening equipment has a particular space available in it to fit the appropriate button cell more accurately. Also, it is next to impossible to use the wrong sizes of the button battery in any hearing device because they do not fit in it.
Types of Hearing aids Batteries
For most of the hearing aid users, everyday choice for hearing aids batteries are the button cell, which is a type of Micro Batteries. These micro-batteries are the small, flat, round shape. Therefore it looks like a customary button. The most common type is a zinc-air button disposable battery. These are air-activated so they do not start loosing their power until getting contact with air.
Among all the rechargeable batteries types, Zinc is the most common type of battery. Zinc-air button cells usually have a tab for the energy source. Previously hearing aids batteries were made using mercury, to provide help in the conductivity and also stabilize the listening device’s internal parts. But today mercury is not used in the ear machine batteries.
Power one hearing aid is made from Varta. Zinc-air hearing aids batteries are manufactured in the world’s largest and most advanced battery manufacturing plant which is located in Ellwangen, Germany. This is well known for its quality and reliability, they are extremely long time lasting and comfortable too.
Best Hearing Aids Batteries
Zinc-air batteries are ideal for today’s digital hearing aids due to its high energy density as well as an almost flat drain curve. This means that the hearing machines can perform at a consistent level throughout the lifetime of the battery. With a protective tab to keep the batteries in an “inactive state”, you can be sure that the batteries you get are in the best possible condition.
As zinc-air batteries are activated with air, hence a factory seal or sticker allows them to remain inactive until it is removed. Once it is peeled from the back of the battery. Then oxygen will react with the zinc in the battery and “turn it on.” To get the best performance from a zinc-air battery, wait about one minute after removing the sticker to fully activate before placing it in the hearing device.
Replacing the sticker will not deactivate the battery, so once the sticker is removed, the battery will remain in an active state until the power is drained. Zinc-air batteries remain stable for up to three years when stored at room temperature and in the dry environment. Storing zinc-air batteries in the refrigerator has no benefits and could cause condensation to form under the sticker, which could reduce battery life prematurely.

Hearing Aid Battery Capacity
Hearing aid last depending on their capacity. The more the capacity, the more the hearing device battery lasts. According to the survey of around 500 hearing aid users, you can have a better idea about the battery life. In this survey, hearing device users were asked about their hearing aid style, the type of brand they use and in case they use streaming technology. These questions are the parameter to judge the usability and popularity of various kinds of hearing aids batteries.
Your hearing device battery life is affected by some of the variables such as –
- Size and type of battery
- Size and type of hearing aid
- The technology level of the machine
- Time duration or number of hours, you are using the battery
- Gain control
- Sound input
- Signal intensity
- Discharge voltage level
- Dry-aid kit usage
- Temperature and humidity
- Environmental factors
Battery Life Formula
To know how long your battery lasts, you need to first calculate the battery life formula. This is the simple equation for estimating battery life –
Battery life (hours) = battery mAh rating / battery current
Hearing Aids Batteries Drain
All the manufacturers have given all the required information about their hearing device battery usage. In the survey mentioned above, as an example, it is shown that Resound datasheet for the Resound LiNX2 LS61 provided information about the hearing device which uses 312 battery drains 1.3 milli-Amps (mA) from the hearing device battery, which when tested in “test mode” through the ANSI S3.22 standard.
Using the battery life formula, estimated the battery life of size 312 hearing aid which has a capacity of 145 milli-Amp-hours (mAh) which is 111 hours.
In the survey, the average receiver-in-canal (RIC) hearing machine user reports total use- time per battery of 82 hours. An expected 6.3 days of battery life is calculated by considering the hearing aid user report time of 13 hours per day and which when compared with Resound’s datasheet. It is found that the datasheet suggests 8.5 days per battery usage by the user.
So, there is a difference between the survey estimates by the hearing device and the hearing aid manufacturer datasheet.
The problem with calculating these estimates
There is a difference because it is difficult to find the estimates using the battery current drain. Usually, hearing machines are kept in test mode while calculating the current drain which results in disabling the advanced processing technologies such as digital noise reduction, wireless connectivity, and feedback cancellation.
Quick Steps To Change Your Hearing Aid Battery
The hearing aid is the most important thing that can change your life. It helps you to stay connected with your family and friends.

- For keeping your hearing aid last longer keep your batteries sealed.
- Do not open until the time you really need to put them to use.
- Try to make use of the oldest package of hearing batteries first.
- Be cautious that after removal of the label they tend to lose power.
- They will get exhausted easily in 4 to 4.5 weeks even if not used.
- It’s better to put them to use right after the removal of the label.
- Batteries when placed in a cool climate last for a longer period of time.
- But please make sure you don’t store them in very cool or hot places.
- Any of that leads to the draining of the battery’s life more quickly.
- At the time of removing the hearing aid battery, remove the tab first.
- Leave it for a few seconds before inserting it in your hearing device.
- Ensure that the changing of your hearing aid batteries is done in an uncluttered place.
- That place having a soft surface like a table with a tablecloth is perfect.
- Before replacing the battery, wash your hands first.
- In case you are not going to use your batteries for a longer period of time.
- Then remove your batteries from your hearing aid entirely.
- As keeping them inside your hearing device can lead to corrosion and damage from trapped moisture.
- As you know, to make your device dry try to use a hearing aid dehumidifier.
- These dehumidifiers and dry storage kits help in protecting your battery and hearing aid both.
Signs to know the battery is in the hearing aid correctly
- The positive sign(+) is generally flat in all the hearing aids.
- The negative sign(-) or the bottom side usually have rounded edges in all the aids.
The negative sign (-) or the bottom side of the hearing device drawer is also found in a rounded shape. Therefore, the battery can easily fit inside if you insert it in the right direction. In some of the hearing device, the battery door didn’t get close unless the battery is placed correctly. Therefore, it is very important to place the battery in the right way.
Hearing Aid Battery Tester
