Hearing Aid Batteries

Cary Audiology offers hearing aid batteries for various types and sizes of hearing aids in Cary, NC, and nearby locations.

Thanks to technological advancements, modern hearing aids now come with rechargeable batteries. When choosing a hearing aid, you should take into consideration what type of power source would work best for your needs – disposable or rechargeable?

The right choice will depend on how often the device needs to be charged in order to maintain its functionality. You can also weigh the pros and cons of having rechargeable batteries versus disposable batteries and see how each option fits into your lifestyle and budget.

Two Types of Hearing Aid Batteries 

Rechargeable Batteries

Rechargeable hearing aids can be plugged into a charger at night. They never need to be taken out of the device. If the hearing aid doesn’t have a battery door, it usually contains a Lithium-Ion rechargeable battery that takes 3-4 hours to fully charge. In most cases, the battery itself should last the entire life of the hearing aid.

Standard Disposable Batteries

Before rechargeable hearing aids were offered for purchase, hearing aids were powered with disposable batteries, specifically zinc-air button batteries. Once the sticker or tab of the disposable battery is removed, it triggers the activation. After a period of time the battery life will drain and require replacement.

Sizes of Disposable Hearing Aid Batteries 

Hearing aids are available in various styles and sizes with different power needs. Bigger hearing aids need larger batteries. Hearing aid batteries are available in five sizes: 5, 10, 312, 13 and 675. Size 5 hearing aid batteries are the least used. The four most common hearing aid battery sizes are smaller than a dime:

  • Size 10 – 5.8 mm wide by 3.6 mm high
  • Size 312 – 7.9 mm wide by 3.6 mm high
  • Size 13 – 7.9 mm wide by 5.4 mm high
  • Size 675 – 11.6 mm wide by 5.4 mm high

Color-coding for disposable hearing aid batteries 

Due to the subtle size differences of disposable hearing aid batteries, it can be hard to notice and difficult to remember. Manufacturers of hearing aid batteries make the packaging color-coded to ensure that finding and purchasing the correct batteries is easier.

  • Size 10 batteries – yellow
  • Size 312 batteries – brown
  • Size 13 batteries – orange
  • Size 675 batteries – blue

Battery Life of Hearing Aid Batteries

A person’s daily wear time will affect the longevity of their disposable battery. Generally, the larger the device, the larger the battery required to power it. A larger battery size typically yields a greater battery life.

The average lifespan of hearing aid batteries is as follows:

  • Size 10 – 3 to 7 days
  • Size 312 – 3 to 10 days
  • Size 13 – 6 to 14 days
  • Size 675 – 9 to 20 days

How To Extend the Life of a Hearing Aid Battery 

Part of taking care of your hearing aid is knowing how to extend the life of hearing aid batteries. Below are some practical tips to practice:

  • Turn off the hearing aid when not in use.
  • Leave the battery compartment door open overnight to allow evaporation of any moisture buildup.
  • Store them at room temperature. Exposure to extreme temperatures may affect battery life.
  • Avoid putting batteries where they may come in contact with metal objects that might short-circuit them.
