Hearing aid batteries come in several standard sizes, each identified by a specific color code or number. The most common types of hearing aid batteries include:
- Size 10 (Yellow): These are small and typically used in smaller-sized hearing aids. They have a shorter lifespan compared to larger batteries.
- Size 13 (Orange): Larger than size 10 batteries, size 13 batteries are commonly used in behind-the-ear (BTE) and in-the-ear (ITE) hearing aids. They offer a longer lifespan than size 10 batteries.
- Size 312 (Brown): This is a mid-sized battery suitable for various hearing aid styles. It strikes a balance between size and lifespan.
- Size 675 (Blue): The largest of the standard hearing aid batteries, size 675 batteries are often used in more powerful hearing aids, particularly those with advanced features.
The color-coding and numbering system helps users easily identify the right battery size for their specific hearing aid model. Additionally, there are two main types of hearing aid batteries based on their chemistry:
- Disposable Zinc-Air Batteries: These are the most common type of hearing aid batteries. They use zinc and oxygen from the air to generate power. Once the tab on the battery is removed, the chemical reaction begins, and the battery starts providing power to the hearing aid.
- Rechargeable Batteries: Rechargeable hearing aid batteries use lithium-ion or silver-zinc chemistry. They can be recharged using a charging station. Rechargeable batteries are becoming more popular as they offer convenience and can be more cost-effective in the long run.
It’s crucial for individuals using hearing aids to check their device’s manual or consult with their audiologist to determine the specific battery size and type recommended for their hearing aid model. This ensures optimal performance and compatibility.
