Hearing Aid Battery Size 10: What It Is, How Long It Lasts, and Where to Buy It Online

Hearing Aid Battery Size 10 is the smallest and lightest hearing aid battery on the market, designed for discreet devices that prioritize comfort and low profile. If you’re a consumer replacing batteries regularly—or a reseller stocking dependable options—knowing how Size 10 works, how long it lasts, and where to buy hearing aid batteries online can save time and money.


What Is Hearing Aid Battery Size 10?

Hearing Aid Battery Size 10 is a zinc-air battery commonly used in completely-in-canal (CIC) and invisible-in-canal (IIC) hearing aids.

Key characteristics:

  • Smallest standard hearing aid battery

  • Zinc-air chemistry (activated by air)

  • Lightweight and discreet

  • Shorter runtime compared to larger sizes

Once the tab is removed, the battery begins activating—so timing matters.


Which Hearing Aids Use Battery Size 10?

Battery Size 10 powers ultra-small hearing aids designed to sit deep in the ear canal.

Common device types:

  • Invisible-in-Canal (IIC)

  • Completely-in-Canal (CIC)

  • Some micro receiver-in-canal models

If discretion is the top priority, Size 10 is usually the trade-off for shorter battery life.


How Long Does Hearing Aid Battery Size 10 Last?

How to Get the Most Life Out of Size 10 Batteries

Size 10 batteries are small, so smart handling matters.

Best practices:

  1. Remove the tab and wait 1–2 minutes before inserting

  2. Turn hearing aids off when not in use

  3. Store batteries at room temperature

  4. Avoid humid storage areas

  5. Don’t refrigerate zinc-air batteries

That short wait after removing the tab allows full air activation and noticeably improves performance.

Why online buying makes sense

  • Bulk quantities for resellers

  • Consistent availability

Specialty battery suppliers like MicroBattery focus on high-turn inventory, which means fresher zinc-air cells and reliable performance.
