Modern hearing aids are small, smart, and powerful — but what keeps them running all day? The answer lies in the tiny yet powerful batteries, often referred to as cells, that provide the essential energy for these life-enhancing devices. In this blog, we’ll answer a common question: Which cell is used in hearing aids?, and explain everything you need to know about hearing aid batteries.
What Type of Cell is Used in Hearing Aids?
The most commonly used cells in hearing aids are zinc-air batteries. These small, button-shaped batteries are specially designed for hearing aids and offer stable power in a compact size.
Zinc-air batteries are activated by air. Once the protective tab is removed, oxygen enters through small holes, triggering a chemical reaction that generates power.
Common Sizes of Hearing Aids Cells
Hearing aids use four standard sizes of zinc-air batteries, each identified by a color code:
| Battery Size | Common Color | Usage Type | Battery Life |
|---|---|---|---|
| Size 10 | Yellow | Mini CIC, IIC | 3–7 days |
| Size 312 | Brown | RIC, ITC | 5–10 days |
| Size 13 | Orange | BTE, ITE | 7–14 days |
| Size 675 | Blue | Power BTE | 9–20 days |
Note: Battery life varies based on device model, usage time, and features like Bluetooth.
At Soft Hear, we help you choose the right battery size based on your hearing aid model and usage habits.
Rechargeable Hearing Aids Cells
Alongside traditional zinc-air cells, many modern hearing aids now use rechargeable lithium-ion batteries. These batteries offer:
-
Longer lifespan (up to 24 hours on a single charge)
-
Eco-friendliness (no disposable waste)
-
Convenience (no battery changes)
-
Built-in charging cases
Rechargeable models are especially popular in premium hearing aids from brands like Phonak, Signia, and ReSound, all of which are available at Soft Hear clinics across India.
Tips for Using and Storing Hearing Aids Batteries
To maximize battery performance:
-
Wait 1–2 minutes after removing the tab before inserting the battery (activates air reaction).
-
Turn off the hearing aid when not in use to preserve battery life.
-
Store batteries in a cool, dry place – avoid extreme temperatures.
-
Keep batteries away from children and pets — they can be harmful if swallowed.
At Soft Hear, we not only provide high-quality batteries but also educate our clients on how to use and store them safely.
