Hearing aids are life-changing devices that help people reconnect with their surroundings, enjoy conversations, and improve their quality of life. Yet, for hearing aids to function at their best, they need a reliable power source. That’s where hearing aid batteries come in.

From rechargeable hearing aid batteries to traditional disposable hearing aid batteries, choosing the right option and understanding how to maintain them is crucial for long-term performance. In this detailed guide, we’ll explore everything you need to know about hearing aid batteries. their types, lifespan, sizes, and tips for replacement.

Why Hearing Aid Batteries Matter

Hearing aids are sophisticated devices, often equipped with features like Bluetooth connectivity, background noise reduction, and directional microphones. All of these functions demand steady power. Without the right battery, even the best-designed hearing aid cannot perform effectively.

When batteries are weak or drained, you may notice:

  • Lower sound quality
  • Reduced amplification
  • Hearing aids shutting down unexpectedly
  • Connectivity issues with Bluetooth-enabled devices

This is why understanding your battery type and how to extend its life is essential.

Types of Hearing Aid Batteries

There are two main categories of hearing aid batteries: disposable and rechargeable. Each has its own advantages and considerations.

Disposable Hearing Aid Batteries

These are zinc-air batteries that come with a small sticker tab. Once the tab is removed, air activates the battery, and it starts working. Common hearing aid battery sizes include 10, 13, 312, and 675, each designed for different types of hearing aids.

  • Pros:

    • Easy to replace
    • Widely available
    • No need for charging equipment

  • Cons:

    • Shorter lifespan (3–10 days, depending on usage)
    • Recurring cost over time
    • Less environmentally friendly

Rechargeable Hearing Aid Batteries

Rechargeable models have become increasingly popular in modern digital hearing aids. Most use lithium-ion technology, similar to smartphones.

  • Pros:

    • Convenient—charge overnight and use all day
    • More eco-friendly than disposable batteries
    • Long lifespan (typically lasting the entire life of the hearing aid)

  • Cons:

    • Require access to a charging unit
    • Higher initial cost
    • May degrade after years of use, requiring professional servicing

At The Hearing Centre Singapore, audiologists can guide you in selecting the right battery type based on your lifestyle, hearing needs, and device type.

Hearing Aid Battery Size Guide

Choosing the correct hearing aid battery size is important, as not all batteries fit every device. The industry uses a standard color-coded system for easy identification:

  • Size 10 (Yellow) – Smallest, used in invisible-in-canal (IIC) and completely-in-canal (CIC) devices
  • Size 312 (Brown) – Common in smaller behind-the-ear (BTE) and receiver-in-canal (RIC) aids
  • Size 13 (Orange) – Used in larger BTE hearing aids
  • Size 675 (Blue) – Largest size, mostly used for power BTE aids and cochlear implants

When getting a new hearing aid, your audiologist will advise which battery size is suitable. If you’re unsure, you can always consult a qualified audiologist in Singapore for guidance.

Battery Life in Hearing Aids

Battery life in hearing aids depends on several factors:

  • Battery size – Larger batteries last longer than smaller ones.
  • Hearing aid features – Streaming music or calls via Bluetooth drains power faster.
  • Usage time – The more hours per day you use your device, the quicker the battery depletes.
  • Environment – Humid climates like Singapore can affect performance.

On average:

  • Disposable batteries last 3 to 10 days.
  • Rechargeable batteries last a full day on a single charge and 3–5 years overall.

For patients receiving hearing loss treatment in Singapore, understanding these factors helps ensure that your device works optimally without interruptions.

Safe Hearing Aid Battery Replacement

When it’s time for hearing aid battery replacement, proper handling is important. Here are some safety tips:

  • Wash and dry your hands before touching batteries.
  • Store batteries in a cool, dry place.
  • Remove the tab only when ready to use the battery.
  • Keep spare batteries away from children and pets.
  • Dispose of used batteries properly, as they contain metals.

If you face frequent issues with batteries dying too quickly, consult a hearing specialist in Singapore to check whether the problem is with the device or the battery.

When to See a Specialist

Sometimes, issues with hearing aid performance are not just battery-related but due to ear conditions. If you notice persistent problems like reduced clarity, tinnitus, or sudden hearing changes, it’s important to get checked.

At The Hearing Centre Singapore, you can access services such as:

Specialists can help determine whether battery replacement is enough or if you need further device adjustments or medical care.

Tips to Extend Hearing Aid Battery Life

To maximize battery life in hearing aids, try the following tips:

  • Open the battery door at night to reduce moisture buildup.
  • Turn off your hearing aids when not in use.
  • Store batteries at room temperature, away from heat and humidity.
  • Use a dehumidifier kit for hearing aids in humid conditions.
  • Avoid carrying loose batteries in your pocket or bag where they can short-circuit.
