Batteries for Your Hearing Devices

Powering Your Hearing, One Charge at a Time.

Hearing aids are tools that help you connect with the world around you. For many people, they are essential, not just convenient. Just like many other devices, they need a consistent power source to function properly and perform at their best. At Denver Audiology, we want to make sure that you understand your options when it comes to hearing aid batteries. We want you to always get the most out of whatever type you end up choosing.

Even small fluctuations in battery power can affect how your hearing aids work. You may have a loss of clarity when listening to others speak, volume issues, or even consistency and performance problems when the hearing aid batteries start to lose power. That is why it is so important to choose the right battery type and know how to handle it the right way. It is also essential to understand when your batteries need to be replaced.

Type of Hearing Aid Batteries

Hearing aid batteries come in several standard sizes; thankfully, they also come color-coded, so it is easy to grab the ones you need if you forget the size that goes in your devices. The standard sizes include:

Size 10 – Yellow

Size 312 – Brown

Size 13 – Orange

Size 675 – Blue

FAQs

The majority of hearing aids that use batteries utilize zinc-air batteries, which activate when exposed to oxygen in the air. This means that to make sure you have fresh batteries, they need to be sealed in the original packaging until you are ready to use them. Once the protective tab has been removed, allow the battery to fully activate for around five minutes before inserting it into your hearing aid to ensure you receive the full power benefits.

Battery Life and Replacement Tips

The life span of a hearing aid battery depends on several different things, such as the type of device, battery size, and how much you use your hearing aids. On average, batteries last:

Small batteries (size 10) last 3–5 days with 12–16 hours of daily use.

Medium sizes (312, 13) last 5–10 days, depending on wear time and power needs.

Larger batteries (675) can last up to 3 weeks with lighter usage.

How to Care for Your Hearing Aids

In order to get the most out of the batteries your device uses, do the following:

Open the battery door at night to allow moisture to escape and preserve the battery.

Turn your hearing aids off when they are not being used.

Store batteries at room temperature in their storage container.

Wash your hands before handling batteries to avoid transferring oils or debris.

Remove dead batteries immediately to prevent swelling or corrosion inside the compartment of your device.

How to Replace a Hearing Aid Battery

Replacing the battery for your hearing device is a straightforward procedure, but it's essential to follow the steps correctly and in order to achieve the best results.

The steps are shared below for convenience:

Open the Battery Door

Use the notch or nail grip to open the battery door.

Remove the Used Battery

Remove the used battery and dispose of it safely.

Prepare the New Battery

Remove the tab from the new battery package.

Wait for Air Activation

Wait 5 minutes to allow air activation.

Insert the Battery Correctly

Insert the battery with the “+” side facing up, aligning it with the symbol on the battery door.

Close the Door Gently

Close the battery door gently—never force it.

Some hearing aids will provide a tone or voice alert to let you know when the battery is low. If your device does not do this, you may still notice that something is wrong. You may notice a distinct reduction in sound quality, distortion, or just abrupt silence. If you replace the battery and a new battery does not fix the issue, you need to take your device for servicing to an expert.

Rechargeable Hearing Aids: A New Age Solution

Recent technology has also enabled the development of rechargeable hearing aids that offer not just convenience but also fewer hassles and more eco-friendly power. You do not need to constantly replace small batteries every other day, but just place your hearing aids in the charging station at night. Once you charge them, you enjoy a full day of continuous hearing.

FAQs

Rechargeable models are much more widely available than ever. They are compatible with most modern hearing aids. There are even some older models that can be upgraded to include a rechargeable option. Some of the other advantages of a rechargeable hearing aid include:

All-day power on a single charge
Quick charging options for busy lifestyles
Eco-friendly – One pair replaces hundreds of disposables
No more battery changes or emergency store runs
Lower long-term cost – Just one battery replacement per year
Easy maintenance – Ideal for those with dexterity challenges

The standard zinc-air battery packs, which are typically sold in packs of 18, range from $10 to $17, depending on the size and brand. This means that you could spend between $30 and $150 annually, depending on how often you replace your batteries and the model of hearing aid you wear.
