FAQs About Hearing Aid Batteries

Batteries are an essential part of your hearing aid. Your audiologist will answer any questions you have about them, but we have listed some helpful information below. 

What battery should I use in my hearing aid?

Hearing aid batteries come in four different sizes: 10, 13, 312 and 675. Battery manufacturers use industry-standard colors to help identify each size:

• Size 10 batteries: Yellow
• Size 13 batteries: Orange
• Size 312 batteries: Brown 
• Size 365 batteries: Blue

The larger the battery the greater the power, but you can find out which size of battery your device needs by referring to the manufacturer's manual. 

How long do hearing aid batteries last?

Hearing aid batteries generally last between three and 22 days. Most hearing aids will give you a warning signal when the battery is about to die. Battery lifespan depends on the type of hearing aid you own, the type of battery you buy and how often you use your hearing aid. 

How can I prolong the lifespan of my hearing aid batteries?

There are a number of things you can do to prolong the lifespan of your batteries.

• Only remove the battery tab when you are ready to use the battery.
• Let your battery breathe for three to five minutes before inserting it into your device.
• Store your batteries at room temperature.
• Leave the hearing aid battery door open to block corrosion.
• Use a hearing aid dehumidifier to absorb moisture out of your hearing aid battery.
• Remove the batteries when you're not using your hearing aid for an extended period of time.

For more advice, speak to your audiologist.

How do I insert a battery into my hearing aid?

Inserting a battery is easy to do. Here are the steps on how to do it:

• Open the door to the battery compartment.
• Place the battery into the hearing aid with the tab facing outward.
• Remove the tab and leave the battery door open for 60 seconds to let the battery air up.
• Securely close the battery door

Changing the batteries can sometimes be difficult for people with poor dexterity, so if you have any problems, speak to your audiologist.

How do I dispose of my old hearing aid batteries?

Hearing aid batteries are made with metals that are toxic to the environment. For this reason, you shouldn't just throw them into the trash, as they will cause environmental damage when they have made their way to your local landfill.

When it comes time to dispose of your old batteries, you have three options:

• Contact your hearing aid provider to see if they have a recycling program in place.
• Look for recycling programs in your local area.
• Contact electronic retailers to see if they have a recycling program in place.

Consider each option when it comes time to dispose of your old hearing aid too.
