What are the different types of hearing aid batteries?

Hearing aid batteries are typically divided into two main categories: disposable zinc-air batteries and rechargeable batteries. Here’s a closer look at each type:

  • Zinc-Air Disposable Batteries: These are the traditional, non-rechargeable batteries used in most hearing aids. Zinc-air batteries are air-activated, which means they start working when the tab is removed, allowing air to enter the battery and start the chemical reaction. They are available in different sizes, each designed for specific hearing aid models. The sizes are color-coded for easy identification:
    • Size 10 (Yellow): Smallest size, commonly used in completely-in-canal (CIC) and in-the-canal (ITC) hearing aids.
    • Size 312 (Brown): Used in in-the-ear (ITE) and some behind-the-ear (BTE) hearing aids.
    • Size 13 (Orange): Larger size, used in BTE and ITE hearing aids, providing longer battery life.
    • Size 675 (Blue): Largest size, typically used in high-power BTE hearing aids and cochlear implants, offering the longest battery life.
  • Rechargeable Batteries: Rechargeable hearing aids use either lithium-ion or silver-zinc batteries. These batteries are designed to last a full day on a single charge, and they are recharged overnight using a charging station. Rechargeable batteries are becoming increasingly popular due to their convenience and environmental benefits.
    • Lithium-Ion Batteries: These are commonly used in many of today’s modern hearing aids. They offer a long lifespan (usually a full day’s use per charge) and can last for several years before needing replacement.
    • Silver-Zinc Batteries: These batteries offer a similar daily charge capacity but are typically smaller, making them suitable for smaller hearing aids. They can be easily replaced by the user, unlike lithium-ion batteries, which usually require professional replacement.

 

Choosing the right type of battery depends on your hearing aid model, lifestyle, and personal preferences. At Melody Audiology, we help you navigate your options, ensuring you have the right batteries that match your hearing needs and provide the best performance for your devices.
