To find the right compatible batteries for your hearing aid, you need to know the hearing aid battery types, size, battery life, brands, and the list goes on.

Which Batteries Are Compatible With My Hearing Aid?

It is not compulsory that every hearing battery type meets the criteria for your given hearing machine. Hearing aid manufacturers have produced various types of hearing aid batteries depending on the need of their weavers.

Types of Hearing Aid Battery

For most of the hearing aid users, everyday choice for hearing aid batteries are the button cell batteries, which is a type of micro-batteries. Micro batteries are the small, flat, round shape which is like a customary button. The most common type is a zinc-air button disposable battery. These are air-activated.

Among all the rechargeable batteries, Zinc batteries are the most common type of battery. Zinc-air batteries usually have a tab for the energy source. Previously hearing batteries were made using mercury, to provide help in the conductivity and also stabilize the hearing device’s internal parts, but today mercury is not used in hearing aid batteries.

Made from Varta, power one hearing aid Zinc-air hearing aid batteries are manufactured in the world’s largest and most advanced hearing aid battery plant located in Ellwangen, Germany. Well known for its quality and reliability, they are extremely long-lasting and comfortable.

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 air-activated, a factory-sealed sticker allows them to remain inactive until it is removed. Once peeled from the back of the battery, oxygen will interact 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.

Battery Life

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.

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

To know how long your battery lasts, you need to first calculate the battery life formula. The simple equation for estimating battery life –

Battery life (hours) = battery mAh rating/battery current.

Hearing Aid Battery 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 in your life, it helps to stay connected, so it is important to keep them at your best size.

1. Step 1: Know when to change the battery. Have you heard that your hearing machine is continuously beeping? In actually it is warning you that the battery needs to be replaced. The warning usually takes from a few minutes to half an hour before starting the battery fully, so replace them quickly.

2. Step 2: Use the right batteries for your hearing equipment. Batteries come in various sizes, types, and performance levels, so it is important to use suitable batteries for your listening devices. Contact your audiologist, which can help ensure that your hearing aids are matched with the appropriate battery products.

3. Step 3: Remove old batteries After detecting the battery door on your listening device, drag or press it to open it using the attached nail grip, stepping, or lever. Remove the old battery, and be sure to check with your city, county, or local domestic hazardous waste management facility for the proper recycling or disposal options.

4. Step 4: Prepare new batteries With the removal of the old battery, remove the colorful tab of the new battery. Allow the new battery to sit three to five minutes before the installation so that it can be activated. Also, make sure you are going to use a new battery, which can not be deactivated after the tab is removed.

5. Step 5: Install new batteries. It is simple to insert a new battery: Just align the bus with the same mark on the battery door on the flat side of the battery, set the battery in place slowly, and close the battery door.

What are the estimates provided by hearing aid manufacturers?

You should keep caution while reading the manufacturer’s estimates because the manufacturers often overestimate the battery life and as there are other factors involved which are mentioned above such as hearing device configuration or lifestyle of the user. It is very difficult to calculate the exact battery life until you are using the hearing device.

Also, some of the hearing aid manufacturer’s estimates are not standardized. As, some of the manufacturers usually use a higher capacity (mAh) battery, which increases the number in the estimated figure when compared to the other manufacturers, who use a standard capacity battery of a similar size.

Hearing Aid Battery Power

The survey estimated the hearing aid battery power based on the hearing device user experiences.

How Long Do Hearing Aid Batteries Last, On Average?

As mentioned above hearing aid lasts depending on their capacity. A small hearing device of size 10 battery has 93  mAh capacity whereas the powerful size 675 shows 627 mAh capacity.

The table shows the Average hours of hearing device use by battery size.

How Long Do Hearing Aid Batteries Last With Audio Streaming?

The table shows Average hours of use without and with audio steaming depending on battery size.

How to extend the life of a hearing aid battery?

There is no step by step way in order to extend battery life. Although, there are tips that will ensure that your hearing device will last longer.

Accidentally swallowed a battery? Call the National Battery Ingestion Hotline: 202-625-3333

Some of the care and maintenance practices are given below to extend your hearing battery life. Follow these best practices to keep your batteries well-maintained and make them last longer:

• For keeping your hearing aid last longer, keep your batteries sealed 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 and get exhausted easily in 4 to 4.5 weeks, 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.
• At the time of removing the hearing aid battery, remove the tab first and 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 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.
• Try to use a hearing aid dehumidifier. As you know, 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.
