Size 10 hearing aid batteries

The smallest hearing aid batteries available, size 10 models, primarily power mini receiver-in-the-ear (RITE) devices and completely-in-canal (CIC) hearing aids. These compact batteries measure 5.8mm in diameter by 3.6mm in height, with all manufacturers adopting a universal yellow coding system for easy identification.

Due to their diminutive dimensions, size 10 batteries are perfectly suited for the most discreet hearing aid styles available today. Users can typically expect each battery to provide power for between 3-10 days, depending on hearing aid usage patterns and features.

Size 13 hearing aid batteries

Orange-coded size 13 batteries are the preferred power source for behind-the-ear (BTE) and in-the-ear (ITE) hearing aid models. These medium-sized batteries feature dimensions of 7.9mm in diameter and 5.4mm in height, with the distinctive orange colour coding providing universal identification across all manufacturers.

The larger capacity of size 13 batteries makes them well-suited to power the more robust features found in BTE and ITE devices. Users can anticipate a battery life ranging from approximately 6 to 14 days, with longevity dependent on individual usage habits and the specific power requirements of their hearing aid's features and amplification needs. 

Size 312 hearing aid batteries

Brown-coded size 312 batteries are commonly utilised in mini behind-the-ear (BTE), receiver-in-the-ear (RITE), and in-the-canal (ITC) hearing aid styles. These batteries measure 7.9mm in diameter by 3.6mm in height, with the universal brown colour identification system used across all battery manufacturers.

The moderate size of 312 batteries makes them an ideal power solution for mid-range hearing aids that require more capacity than the smallest models but don't need the full power of larger batteries. Users can generally expect these brown batteries to provide reliable power for approximately 3 to 10 days, with actual performance varying based on hearing aid usage patterns and device power consumption.

Size 675 hearing aid batteries

Blue-coded size 675 batteries are specifically designed for high-power behind-the-ear (BTE) hearing aids that require maximum energy output. As the largest standard hearing aid battery available, measuring 11.6mm in diameter and 5.4mm in height, these batteries are engineered to support the most demanding hearing aid applications.

The substantial size of 675 batteries translates directly into superior longevity, making them the longest-lasting option in the hearing aid battery range. Users can typically expect each blue battery to deliver consistent power for approximately 9 to 20 days, providing exceptional value for those with severe hearing loss who rely on high-powered amplification systems.

Cost of hearing aid batteries

Hearing aid batteries in Australia generally cost between $10-30 per pack, depending on the battery size and brand you choose.

How long do hearing aid batteries last?

Many factors can influence how long each hearing aid battery lasts. The type of hearing aid, the amplification power, and the available features all play a part in battery length. For example, more hearing aid power is required when streaming television or music. Standard hearing aid batteries can last between 3 to 22 days.

How often do you need to change hearing aid batteries?

Hearing aid battery longevity typically ranges from 3 to 22 days, with actual performance influenced by several key factors including your specific hearing aid model, battery type, and daily usage duration. Individual listening habits and device features significantly impact overall battery life expectancy.

Several warning signs indicate when battery replacement becomes necessary. If you notice sound quality becoming unclear or distorted, or find yourself turning up the volume beyond your usual settings, these symptoms often signal declining battery power. Many modern hearing aids incorporate low-battery warning systems that emit brief beeping sounds when replacement becomes urgent - immediate battery changes are essential upon hearing these alerts.

To prevent unexpected hearing aid failure, it's advisable to carry spare batteries at all times. When storing replacement batteries, ensure they remain separate from metallic items such as coins, keys, or other metal objects, as contact can cause premature battery discharge and reduce their effectiveness when needed.

How to get the most from your hearing aid batteries

1) Battery activation tip

Our hearing aid batteries are air-activated, which means they do not begin working until the coloured tab is removed and air enters the battery cell. Remove and discard the tab only when you are ready to use the battery. The tab cannot be reused.

2) Conserve battery overnight

When not in use, it’s suggested to turn off the hearing aid batteries. To do this all you need to do is open the battery door. The added benefit from leaving the battery door open is that it allows any excess moisture to dry out, this helps extend the life of your hearing aid batteries and your hearing aids.

3) Storing hearing aid batteries

The ideal temperature for hearing aid batteries is between 10 and 25°C, so it is recommended to keep them in a dry area inside at room temperature.
Due to the small battery size, ensure they are kept out of reach around children.

4) Battery life length

Get the most out of your hearing aid batteries by turning them off at night and reducing your streaming of television or music.

FAQs on hearing aid batteries and rechargers

Why are my hearing aid batteries dying so fast?

If your hearing aid batteries are dying too fast, the battery may be getting depleted by moisture which makes it less reliable. Ensure you follow our tips to get the most from your hearing aid batteries. If you have noticed a change in how long your batteries last, we suggest you visit your local clinic for a free clean and check of your hearing aids.

Should you change both batteries at the same time?

It is not necessary to change both hearing aid batteries at the same time. You will receive a similar performance from two hearing aids regardless of battery life. It is recommended to replace your batteries either when they die or on a regular basis on the same day - whichever works best for you.

What to do with dead hearing aid batteries?

Most hearing aid batteries contain zinc. Whilst convenient, you should never dispose of your zinc batteries in household waste as it is harmful for the environment. Instead look for drop off centres which accept batteries.

Which is better: a hearing aid with battery or rechargeable?

Both options have pros and cons. Here’s a quick breakdown:

Battery-powered hearing aids:

  • Easy to replace batteries
  • Widely available
  • Frequent replacements needed
  • Less eco-friendly

Rechargeable hearing aids:

  • Convenient daily charging
  • More environmentally friendly
  • Ideal for users with dexterity issues
  • Higher upfront cost

Are hearing aid batteries free?

In Australia, free hearing aid batteries for pensioners and seniors may be available under the Hearing Services Program (HSP). Eligibility includes:

  • Age Pension recipients
  • Veterans Affairs card holders
  • Aboriginal and Torres Strait Islander peoples (in some cases)

Contact your local Amplifon clinic or visit the Hearing Services Program website for more details. Terms and conditions apply under the Hearing Services Program.

Are hearing aid batteries lithium?

No. Most disposable hearing aid batteries are zinc-air batteries, not lithium. Zinc-air batteries activate when exposed to air and are safe, lightweight, and reliable for medical devices.

Rechargeable hearing aids, however, often use lithium-ion technology, which is durable and long-lasting.

Can hearing aid batteries be recycled?

Yes, hearing aid batteries can be recycled, but not through regular household recycling bins. Look for:

  • Special bins at hearing clinics or pharmacies
  • Local council hazardous waste collection points

Never throw batteries in general waste, as they can be harmful to the environment.
