How Long Do Hearing Aid Batteries Typically Last?

Whether you’re researching the difference between disposable and rechargeable hearing aid batteries or looking to learn more about maintenance for your device, our team at Sound Advice Hearing Doctors, with locations in MO, AR, and OK, can help you get the most out of your hearing aids. For many with hearing loss, hearing aids significantly improve daily life. Most modern hearing aids now come equipped with rechargeable batteries, a feature welcomed for its convenience and ease. However, if your device isn’t rechargeable, understanding the typical lifespan of hearing aid batteries is crucial for maintaining the optimal performance of these products.

What Determines Hearing Aid Battery Life?

No matter which type of battery your device uses, its longevity is affected by various factors. Battery life can vary significantly depending on:

• Battery Size – Battery power for any electronic equipment is determined by the battery’s size. Even when it comes to tiny batteries that fit into hearing aids, the slight difference in size among the various options will make a difference.
• Hearing Aid Size – Hearing aid size comes into play for different reasons. For one, smaller devices can only accommodate smaller batteries, which means shorter life. But a larger device with more features will also draw more from its battery.
• Usage Habits – How long you use your hearing aid during the day will affect battery life. If you wear them all day, they will need to be replaced or recharged more frequently than those who only wear them in limited scenarios throughout the day,
• Hearing Aid Style – Certain styles may consume more power due to their features and technology.

Disposable Battery Lifespan

Among disposable battery options, there are several types that have predominantly been used in hearing aids. Since the devices range in size, batteries do too. Here is a general guide on how long each type lasts, but remember that the actual time will differ for every user.

• Size 10 Hearing Aid Batteries – This is the smallest size used in invisible-in-canal (IIC) and completely-in-canal (CIC) devices, which last three to seven days.
• Size 312 Hearing Aid Batteries – These are most common because they’re found in the most popular types of devices, including receiver-in-the-canal (RIC), mini behind-the-ear (BTE), and in-the-canal (ITC) products. They last three to 10 days.
• Size 13 Hearing Aid Batteries – Standard BTE and ITE hearing aids use these, lasting from six to 14 days.
• Size 675 Hearing Aid Batteries – The largest size lasts nine to 12 days and is used to power hearing aids with more power needs.

Rechargeable Hearing Aid Batteries

Rechargeable batteries are a game-changer for hearing aid users, ending the constant need for replacements. Rechargeable hearing aid batteries are becoming the norm in modern devices as disposable batteries continue to be phased out. Since hearing aids are small, the batteries are small, so eliminating the need to handle and switch out tiny batteries is a welcome change for users. Ask your hearing care provider about rechargeable options during your hearing test and assessment. How long do hearing aid batteries last when fully charged? It will all vary, but users should know:

• Hearing aids can be worn about 16 hours per day and will require charging nightly
• The device’s power consumption will vary with its size and style
• The use of advanced features like Bluetooth technology and streaming can drain batteries quicker

Replacement of Rechargeable Batteries

While modern convenience favors rechargeable batteries, they don’t last forever. Based on the manufacturer’s specification and usage, rechargeable batteries in hearing aids can often last one to four years before requiring replacement. Hearing aids themselves last anywhere from three to seven years. Your rechargeable batteries could last long enough that by the time they need to be replaced, it will also be time to replace your hearing aids. However, if the rechargeable batteries need to be switched out but the hearing aids are still in good condition, our hearing care professionals are here to assist with that process.

Recognizing When to Replace Hearing Aid Batteries

It’s essential to recognize the signs when your hearing aid batteries need attention. These include:

• A decline in sound quality or intermittency
• The hearing aid no longer powers on, or it turns off unexpectedly
• You receive a ‘low battery’ indicator or hear a low battery beep

Tips for Maximizing Battery Life

Here are ways to ensure you get the most out of your hearing aid batteries:

• Turn off hearing aids when not in use
• Store batteries and hearing aids in dry, room-temperature environments
• Use a hearing aid dehumidifier overnight
