Hearing Aid Battery Sizes

It’s important to recognize which battery works for your hearing aids and how your lifestyle and usage affect their performance. At Toronto Family Hearing, we offer various high-quality hearing aid batteries for different hearing aid models. For individuals who want to upgrade from disposable batteries, we also offer rechargeable hearing aids.

Size 10

These are the smallest hearing aid batteries used to power the smallest hearing aids on the market. They usually need to be changed every few days.

Size 312

These batteries are the most common size found in hearing aids. They will usually last about one week, depending on hearing aid use.

Size 13

These batteries tend to offer better longevity, depending on the degree of hearing loss, for larger hearing aids. On average, they last between 7 to 10 days.

Size 675

The largest batteries in size and power and used for larger hearing aids and cochlear implants.

How Long Do Hearing Aid Batteries Last?

There are several factors that can impact the longevity and performance of your hearing aid batteries. The size of the battery, your hearing aid model, and your lifestyle can affect the battery’s lifespan. Your hearing aids will notify you when you need to change your batteries by either emitting a beeping sound or telling you directly. We can offer advice and guidance for getting the most out of your batteries.

Maximize Your Hearing Aid Batteries

Store at Room Temperature

Hearing aid batteries are best stored at room temperature. Exposing your batteries to extreme temperatures with excessive condensation (such as leaving them in the refrigerator) can reduce their lifespan, resulting in you replacing your batteries sooner. Ideally, it's best to keep your hearing aid batteries in a safe dry place, away from direct sunlight and water, such as your bedside table or drawer.

Turn Hearing Aids Off When Not in Use

It's recommended that you turn off your hearing aids when you are not using them, such as when you're going to bed or having a shower. Simply leave the battery door open, as this helps dry out any moisture that has accumulated within the device. Turning off your hearing aids when you’re not using them can prolong their lifespan, ensuring you have fully functional hearing aids for the important things in life.

Extend The Life of Zinc-Air Batteries

Standard hearing aid batteries are classified as zinc-air, which activate when exposed to oxygen. Once you remove the sticker from the battery (which prevents oxygen from activating it), wait 20 seconds before inserting the battery into your hearing aids. This delay will extend the battery life, as it lets in the maximum amount of oxygen before use. Our professionals are happy to discuss management tips with you at any time.

We’re Happy to Answer All Your Questions

It all depends on the hearing aid device you use, your hearing loss and your lifestyle usage. Our professionals will happily discuss your options, so you get the most out of your batteries. If you’re tired of changing your batteries constantly, talk to us about rechargeable hearing aids.

If you put the sticker from the battery on your calendar, you can track battery usage and better predict when you’ll have to change your batteries (and avoid a situation where you don’t have a spare). This trick will also help you track any potential issues if the batteries aren’t lasting as long as they should.

Ideally, purchasing a 6 month supply of batteries at a time, or 1-2 boxes, is best. Plan to buy more hearing aid batteries once you’re down to your final four. This ensures you always have spares on hand when you need them.

Your battery size varies depending on your hearing aid model. There are four sizes of batteries available, from smallest to largest: Size 10 (Yellow), Size 312 (Brown), Size 13 (Orange), and Size 675 (Blue). Our professionals will explain which battery fits with your device.

It can be confusing changing your battery for the first time, particularly as each model is different. Our audiologists will go over the process with you, so you can feel confident the next time you have to do it. If you still have problems with changing your battery or suspect you might need hearing aid repairs, our team is ready to help.

Keep your batteries stored at room temperature, away from extreme heat and cold. Placing them in a drawer or bedside table is your best bet.
