Learn More About Hearing Aid Batteries
Hearing aids rely on batteries as their power source. Every device, from discreet completely in canal (CIC) and behind the ear (BTE) models to advanced Bluetooth hearing aids, depends on a stable energy supply to operate effectively. The two main types used in Australia today are rechargeable and traditional disposable hearing aid batteries.
Rechargeable hearing aid batteries provide convenient and long lasting power for many modern devices. Meanwhile, disposable zinc-air batteries remain popular for their reliability and easy availability across pharmacies, supermarkets, and audiology clinics. Hearing aid batteries can also be ordered online and delivered straight to your door.
Understanding how these batteries differ, their lifespan, care requirements, and environmental impact, can be beneficial for optimal performance and long-term hearing aid care and maintenance.
Australian Consumer Law ensures that consumers purchasing hearing aid batteries receive products that meet acceptable quality and safety standards.
Types of Hearing Aid Batteries
Hearing aid batteries vary by chemistry type and size, both of which influence device compatibility and battery life.
Common Hearing Aid Battery Types and sizes in Australia
| Type | Size Codes | Chemistry | Rechargeable | Common Use |
|---|---|---|---|---|
| Zinc-air | Size 10, Size 312, Size 13, Size 675 | Zinc-air | No | Traditional hearing aids |
| Lithium-ion | Integrated or removable | Lithium-ion | Yes | Modern RIC/BTE models |
| Silver-zinc (uncommon) | Size 312 | Silver-zinc | Yes | Select |
Rechargeable batteries, primarily rechargeable lithium-ion batteries, offer long-lasting power and a reduced environmental footprint. They are integrated into newer hearing aid models and can typically power the device for a full day on a single charge. Disposable zinc-air batteries (activated when exposed to air) are easily replaced for those with good dexterity, making them a practical option for users who prefer not to charge daily.
| Battery Size | Colour Code | Diameter (mm) | Height (mm) | Typical Weight (g) |
|---|---|---|---|---|
| Size 10 | YELLOW | 5.8 | 3.6 | ~0.3 |
| Size 312 | BROWN | 7.9 | 3.6 | ~0.5 |
| Size 13 | ORANGE | 7.9 | 5.4 | ~0.8 |
| Size 675 | BLUE | 11.6 | 5.4 | ~1.8 |
Battery Life and Performance
Battery performance depends on multiple factors: device model, battery chemistry, daily usage, and environmental conditions. Rechargeable hearing aids usually provide up to 20 hours of use per charge, while traditional disposable batteries may last anywhere from three days to two weeks. Some rechargeable hearing aids, such as the Diamond Stream 12 Bluetooth Rechargeable Hearing Aid, have a charging case that doubles as a power bank, providing enough energy for three extra top-ups without a wall socket. That’s up to 72 hours of total listening battery life.
Average Hearing Aid Battery Life (Indicative)
| Battery Size | Average Life (Standard Use) | Average Life (Heavy Use or Streaming) |
|---|---|---|
| Size 10 YELLOW | 3 – 5 days | 1 – 2 days |
| Size 312 BROWN | 5 – 7 days | 2 – 4 days |
| Size 13 ORANGE | 7 – 10 days | 3 – 6 days |
| Size 675 BLUE | 10 – 14 days | 5 – 7 days |
Factors affecting battery life:
- Wireless streaming: Bluetooth use increases power draw.
- Ambient temperature: Heat and humidity shorten zinc-air battery life.
- Daily use: The longer the aid is worn, the faster the discharge.
- Storage habits: Keeping batteries in cool, dry places preserves charge.
Rechargeable batteries are generally more resilient to environmental fluctuations but require consistent nightly charging. Disposable users benefit from rotating spare packs and allowing new batteries to “air activate” for a minute before inserting them.
Environmental Responsibility
Battery stewardship is an increasing area of focus in Australia. Through national initiatives such as B-cycle, consumers can return used batteries to participating collection points, where they are safely transported, processed, and recycled. The recovered materials, such as zinc, steel, and other metals, are then reused in new products, reducing landfill waste and conserving natural resources.
Hearing Aid Battery Care
Proper maintenance extends both hearing aid and battery lifespan.
Care guidelines:
- Keep the battery compartment clean: Dust or moisture can corrode contacts.
- Store batteries properly: A cool, dry environment away from metal prevents short-circuiting.
- Avoid touching terminals: Oils from fingers can reduce conductivity.
- Open the hearing aid door overnight: Allows moisture to evaporate and prevents drain.
Safety note: Batteries are hazardous if swallowed.
The Poisons Information Centre (13 11 26) offers immediate advice in battery-related emergencies.
Disposable Hearing Aid Batteries
These remain the most widely used hearing aid power source in Australia. The zinc-air variant dominates the market for its reliability and energy density – they are used in most hearing aids, including behind the ear and in the ear (or in the canal) models. Once unsealed, the battery reacts with oxygen to produce power until depleted.
They are generally available in four sizes: size 10, size 13, size 312, and size 675. Hearing aid batteries are colour coded for easier identification as follows: Yellow (Size 10), Brown (Size 312), Orange (Size 13), and Blue (Size 675).
Advantages:
- Readily available at supermarkets, pharmacies, and audiology clinics.
- Suitable for users without easy access to charging facilities.
- Cost-effective in the short term.
Disadvantages:
- Generates waste.
- Performance varies with temperature and altitude.
- Requires frequent replacement.
- Difficult to handle and replace for users with low or reduced dexterity.
- Getting the battery door open can be finicky with smaller hearing aids

Hearing aid batteries can be hazardous to pets if accidentally ingested. Dogs and cats are often attracted to the small, shiny appearance of batteries and the scent of earwax residue on used ones. Even a single zinc-air or lithium-ion cell can cause chemical burns or heavy metal toxicity if swallowed.
Preventive steps:
- Store spare and used batteries in closed containers, out of reach of pets.
- Dispose of spent batteries promptly using approved B-cycle drop-off points.
- Check the floor and furniture regularly for dropped batteries during battery changes.
If ingestion is suspected, contact a veterinarian immediately or call the Poisons Information Centre (13 11 26) for guidance. Early intervention is essential, as batteries can cause internal injury within hours.
Travelling with Hearing Aid Batteries
Travel introduces additional considerations for hearing aid users. Battery life, temperature changes, and airline restrictions can affect how devices perform while away from home.
Before departure:
- Pack extra disposable batteries or ensure chargers and adapters are compatible with your destination’s voltage.
- Keep batteries in their original packaging to avoid short-circuiting.
- Store them in hand luggage rather than checked baggage, where extreme temperatures can occur.
During flights:
- Hearing aids can remain on during security screening and flights.
- Lithium-ion rechargeable batteries under 100 watt-hours are generally allowed in carry-on luggage under Civil Aviation Safety Authority (CASA) guidelines.
Check airline-specific rules for medical electronic devices if unsure.
