Hearing Aid Battery Lifespan

How Long Do Hearing Aid Batteries Last?

With the rapidly aging population, hearing aid technology has evolved drastically, and the number of users is continually increasing. However, a common question that looms in the minds of both first-time users and experienced wearers is, “How long do hearing aid batteries last?” The answer varies depending on many factors, such as the battery size, hearing aid style, power requirements, and hours of use. Let’s dive into these factors to provide a comprehensive answer.

Hearing Aid Battery Sizes

Typically, there are four sizes of hearing aid batteries: 10 (yellow), 312 (brown), 13 (orange), and 675 (blue). The smaller the size, the shorter the lifespan of the battery. Size 10 batteries can last between 3-7 days, while size 312 batteries can run for about 7-10 days. On the other hand, size 13 batteries tend to last for 10-14 days, and size 675 batteries can work for up to 14-20 days.

Hearing Aid Style

The style of the hearing aid also plays a significant role in determining the battery life. Devices with more features or power requirements, such as those providing profound amplification or wireless streaming, tend to drain the batteries faster. Consequently, smaller, in-the-ear (ITE) models that have limited space for batteries will generally have a shorter battery life compared to larger, behind-the-ear (BTE) models, which can accommodate larger batteries. A hearing care provider will be able to help you determine what style is right for you. For the Pasadena and Thousand Oaks communities, our office offers a variety of hearing aid styles.

Power Requirements

The amount of hearing loss an individual experiences directly impacts the power required from the hearing aid, which in turn affects the battery lifespan. A device configured for profound hearing loss requires more power and drains the battery faster compared to a device designed for mild or moderate hearing loss.

Hours of Use

The more you use your hearing aid, the quicker the battery will run out. If you use your hearing aid for a few hours a day, your batteries will last significantly longer than if you use the device all day.

Battery Care and Storage

Proper care and storage can also impact your hearing aid battery life. It’s recommended to store batteries in a dry place at room temperature to maximize their lifespan. Avoid storing them in hot areas or in the fridge, which used to be common advice but is now known to cause harm to the batteries. When you’re not using your hearing aid, turn it off or open the battery door to reduce battery drain.

Hearing aid battery life is dependent on several factors, so it’s not a one-size-fits-all scenario. Generally, it’s always a good idea to keep spare batteries on hand and remember to take good care of them to maximize their lifespan. Monitoring your device’s performance and keeping an eye on battery life can help ensure your hearing aid is always ready when you need it. Any concerns you have with the performance of your hearing aid should be addressed with a hearing care provider.

Communication is a crucial part of our daily lives. Properly functioning hearing aids contribute significantly to our quality of life. Don’t let the worry of battery life keep you from experiencing the world of sounds around you.
