Hearing Aid Batteries

Finding the right batteries for hearing aids has been simplified and is decided by brand. Although size and type recommendations are important, a color-coded system keeps things standardized. Pacific Audiology Clinic can help with the process before and after the initial fitting. For hearing aid batteries, patients will get all the information they need from professionals and the included guide. 

Zinc-air technology

Hearing aid batteries are powered by zinc-air technology. It uses oxygen and other unique materials to create a long-lasting battery with the lowest amount of interference. This applies to disposable battery types, and they are identified by a tab or sticker seal on the surface. This prevents dry out, so should only be removed when they are ready for use. Like any other type of battery, zinc-air performance is related to the environment it’s used in. Modern hearing aids with updated features will use more juice than traditional hearing aid devices. 

Main battery types

There are a lot of main battery types, so a standard was put in place to make things easier for patients. The color-coded system consists of four main batteries, and all of them are considered to be the most commonly used. 

  • Blue (#675) – Commonly used in Behind-The-Ear hearing aids, the 675 batteries can last up to 300 hours
  • Brown (#312) – Lasting up to 175 hours, these are one of the smallest from the main group and are used with In-The-Canal and In-The-Ear devices
  • Yellow (#10) – Yellow is usually attached to In-The-Canal and Completely-In-Canal hearing aids. On a single charge they can last up to 80 hours
  • Orange (#13) – Behind-the-Ear and In-the-Ear use size 13 batteries, capable of up to 240 hours on a single charge

Rechargeable batteries

Rechargeable hearing aid batteries are great for users that don’t want to swap their old batteries out. Its advantages don’t end there, as there are many pricing and quality of life improvements when using a rechargeable system. Getting the most out of rechargeable hearing aids requires understanding when and how to recharge. With the right setup, users can max out the capacity of a battery and only charge it when absolutely needed. Here are the benefits of rechargeable batteries;

  • Hybrid rechargeable devices can use normal hearing aid batteries during the charging period
  • Fast charging is possible with specific brands
  • Rechargeable batteries work well with modern hearing aid features and multiple connections
