Interested in learning about the expected lifespan of your hearing aid's battery? This article provides valuable insights that you don't want to miss.

Hearing aids are a critical component for individuals who suffer from hearing loss. They help amplify sounds so that those with hearing loss can experience the world around them more fully. However, hearing aids require batteries to function, and the lifespan of these batteries is a critical factor in the overall effectiveness of the device.

In this article, we will explore how long hearing aid batteries last, what factors affect their lifespan, and how to prolong the life of your batteries.

How long do hearing aid batteries last?

Hearing aid batteries come in different sizes, and their lifespan can vary depending on several factors. On average, the lifespan of a hearing aid battery is between three and seven days. However, this estimate can vary depending on the size of the battery, the type of hearing aid, and the amount of usage.

The most common sizes of hearing aid batteries are 312, 13, 10, and 675. The 312 battery is the most popular size and is commonly used in behind-the-ear (BTE) and in-the-ear (ITE) hearing aids. This size typically lasts between three and seven days. The 13 battery is commonly used in BTE hearing aids and lasts between six and 14 days. The 10 battery is used in ITE and CIC (completely-in-canal) hearing aids and lasts between three and seven days. The 675 battery is used in larger BTE hearing aids and lasts between nine and 20 days.

What factors affect hearing aid battery life?

Several factors can affect the lifespan of hearing aid batteries. These include:

Battery size: As mentioned, the size of the battery is a significant factor in how long it lasts.

Type of hearing aid: The type of hearing aid affects how much power it requires to function. BTE and ITE hearing aids require more power than CIC hearing aids, which can impact battery life.

Usage: The more often you use your hearing aids, the more quickly the batteries will drain. Additionally, the amount of time you use your hearing aids per day can impact battery life.

Environmental factors: Temperature, humidity, and altitude can all impact battery life. Extreme temperatures can cause batteries to drain more quickly, while high humidity can cause moisture to build up and damage the battery.

Type of battery: Different types of batteries have different chemistries, which can impact how long they last. Zinc-air batteries, which are the most common type of battery used in hearing aids, rely on air to activate them. Once you remove the sticker from the battery, it begins to discharge, even if it is not in use.

How to prolong the life of your hearing aid batteries

While hearing aid batteries are an essential component of the device, they can be costly and inconvenient to replace frequently. Here are some tips to help you prolong the life of your hearing aid batteries:

Store batteries properly: Keep your hearing aid batteries in a cool, dry place, away from direct sunlight or heat. Avoid storing them in the bathroom, as the humidity can impact battery life.

Open the battery door: When you are not using your hearing aids, open the battery door to allow air to circulate. This will help prevent moisture buildup and prolong the life of the battery.

Turn off your hearing aids: If you are not using your hearing aids for an extended period, turn them off. This will help conserve battery life.

Use the right size battery: Using the correct size battery for your hearing aid will help ensure that it functions properly and prolong the life of the battery.

Use hearing aid accessories: Some hearing aid accessories, such as remote controls and Bluetooth streamers, can drain your batteries more quickly. Use these accessories sparingly to conserve battery life

Use rechargeable batteries: Rechargeable hearing aid batteries are becoming increasingly popular, and for good reason. They can save you money in the long run and are better for the environment. However, it is important to note that rechargeable batteries have a limited lifespan, and you will eventually need to replace them.

Keep the batteries fresh: Check the expiration date on your batteries before purchasing them. Using expired batteries can impact their lifespan and performance.

Clean your hearing aids regularly: Buildup of wax, dirt, or other debris can interfere with the function of your hearing aids and cause the battery to drain more quickly. Clean your hearing aids regularly to prevent this.

Use a hearing aid dehumidifier: Moisture can damage your hearing aids and impact battery life. Using a hearing aid dehumidifier can help remove moisture and prolong the life of your hearing aids and batteries.

Consider upgrading your hearing aids: If you are experiencing frequent battery drain, it may be time to upgrade your hearing aids. Newer hearing aids often have more efficient power consumption and longer battery life.

The Bottom Line

The lifespan of hearing aid batteries can vary depending on several factors. However, with proper care and maintenance, you can prolong the life of your batteries and reduce the frequency of battery replacements.

By following the tips outlined in this article, you can ensure that your hearing aids are functioning optimally and that you are getting the most out of your investment. If you have concerns about your hearing aid batteries or are experiencing frequent battery drain, consult with your hearing healthcare provider for personalized recommendations.

A hearing aid is a device that amplifies sound waves to make them louder so they can be heard better with pure and refined quality if you’re experiencing hearing loss. Usually, it has one or more tiny microphones inside that picks up the sound, an amplifier that does the job in increasing the sound volume, and speakers that will send this improved and amplified sound to your eardrums so you can hear them better. This may be worn in or behind the ear, depending on the design and style.

The price of a hearing aid may vary and this would greatly depend on several factors such as the hearing aid type, the technology being used, and the available features. On average, a basic pair of adult hearing aids may cost around $2,000 and $3,000, while the advanced models with more features and better technology may have higher price tags.

There is no definitive answer to which hearing aid brand or model is the best, as it all comes to your specific hearing conditions, preferences, needs, and budget. Every hearing aid manufacturer may offer their devices with different kinds of features and this could significantly affect their prices. Some of the most popular hearing aid brands include Jabra, Eargo,, Audious, MD Hearing, and Audien, so it’s worth checking out their products.
