Batteries, power hearing aids, and different models use different types of batteries, which all require different care levels. However, many still opt for traditional replaceable button batteries’ modern rechargeable hearing aid battery offers wearers a more convenient and cost-effective solution than ever before. 

In this blog post, we’ll cover all the types of hearing aid batteries and examine how each model works to determine which one might best suit your needs. 

So, whether you’re new to using hearing aids or looking for advice on switching from one type of device to another, this guide will help make your next step easier!

Two main types of hearing aid batteries

Two hearing aid batteries are available in today’s market for people with hearing loss- rechargeable and disposable. 

Rechargeable hearing aids require the user to plug in their device overnight to a wall charger, typically providing up to 24 hours of listening time on one charge. 

Disposable or traditional hearing aid batteries, on the other hand, are available in sizes ranging from 10A to 13 zinc-air cells. These models offer power for up to 7 days, depending on their size and the user’s listening needs. 

Ultimately, both types provide a reliable energy source for individuals with hearing aids, allowing them to stay connected with the world.

Rechargeable Hearing Aid Batteries Overview

Rechargeable batteries are revolutionizing the world of hearing aids. They are an excellent innovation for many people with hearing loss.

People with hearing impairments no longer have to worry about constantly replacing their hearing aid batteries since modern rechargeable models allow them to recharge their battery, usually after a few hours of charging, and then return to enjoying improved sound quality without the hassle of tiny button batteries. 

Modern rechargeable hearing aid batteries have various protective functions, such as overcharge and temperature protection. These options help make sure your device is always safe and provides optimal power efficiency. Even better, many of these devices can last up to 24 hours, making them incredibly convenient for everyday use!

How Do Rechargeable Hearing Aids Work?

Rechargeable hearing aids utilize the same technology as power banks since they enable wearers to plug their devices into a charging station at night and wake up with a full battery ready for the day. This is convenient since it eliminates having to constantly remember to buy and change out button batteries every few days. 

Not only does this feature provide convenience, but it can also lower overall costs related to buying additional batteries. Although rechargeable hearing aids sometimes come at a higher initial cost than their non-rechargeable counterparts, they quickly pay for themselves over time – making them an ideal choice for those wanting long-term value from their devices.

How Long Do Rechargeable Hearing Aid Batteries Last?

With rechargeable batteries becoming ever more popular in hearing aids, it’s no surprise that their extremely long life cycle is becoming an attractive bonus to those with hearing difficulties. 

Rechargeable hearing aid batteries last for many usages. Some models give wearers up to 30 hours of power from one charge. While battery performance depends on the make and model of the hearing aid, most rechargeables can last between 24 and 36 hours above a 50 percent volume setting before recharging. 

Generally, once charged every night, battery replacement cycles can last several months or even a year before needing a new battery.

How Do You Recharge Hearing Aid Batteries?

Replacing batteries in hearing aids isn’t the most convenient task; it can be time-consuming and messy. To simplify this chore, some hearing aid models now come fitted with rechargeable batteries – which are much easier to keep power and running smoothly. 

Recharging your hearing aid batteries is simple; place them in a charging unit overnight (or five to seven hours for a full charge), and you’re good to go! This is an easy solution for keeping your hearing aids up and running all day! Charging units are small and discreet, so your battery charging won’t disrupt everyday life.

Standard Disposable Hearing Aid Batteries

Hearing aid batteries are essential in providing users with convenience and powered performance. Zinc-air button batteries have quickly become the standard for disposable hearing aid batteries due to their portability, reliable power output, and low maintenance upkeep. 

Utilizing zinc dioxide to generate power oxygen from the air, these energy capsules can be used for anywhere from 3 to 14 days, on average. Being small and lightweight makes them ideal for travel and everyday tasks, such as listening to music or attending meetings. Plus, most models of hearing aids are compatible with button batteries, giving wearers additional flexibility when it comes to their battery choice. 

Sizes Of Disposable Hearing Aid Batteries

Disposable hearing aid batteries can come in various sizes and are often referred to by their size number, such as 10, 312, 13, and 675. These numbers can provide clues about the battery’s shape and specifications. 

The model type 10 and 312 batteries are typically the smallest in size and have become popular choices for receivers due to their discreet form factor. Meanwhile, 13 and 675-type batteries are more significant than the first two sizes. However, they are still comfortably small for behind-the-ear hearing aids or other receivers. 

Ultimately, the size chosen depends on the individual and their specific device. Still, it is essential to always note the battery number before replacing it.

Color-coding For Disposable Hearing Aid Batteries

How To Extend The Life Of A Hearing Aid Battery

Maintaining hearing aid batteries is integral to maintaining a healthy lifestyle for those with hearing impairments. Handling and storing your hearing aid batteries correctly can help you get the most out of them. Store your battery correctly when not in use by keeping it away from moisture and extreme temperatures to prolong its’ longevity. 

It’s also best to turn off the hearing aids completely when not in use, as leaving them on in standby mode can drain the battery over time. For rechargeable hearing aids, investing in a portable charger can help maintain the battery’s charge so that it’s ready to go when you need it.

Hearing Aid Battery Safety

With advancements in battery technology, rechargeable batteries have become the norm in many hearing aid models. While these are more economical and convenient, they can also pose an additional risk due to their lithium-ion makeup. 

Users should always be sure to treat them safely and with care, following all of the instructions provided by the manufacturer while charging or replacing batteries. 

It’s also important to remember that, if dropped, a rechargeable cell can ignite due to the high-pressure situation created in case of punctures. So for those wearing hearing aids with rechargeable batteries, special attention should be paid to battery usage and safety instructions.

There are multiple options when it comes to purchasing hearing aid batteries. Depending on the make and model of your hearing aid, you might be able to find replacement batteries in stores selling hearing aids and electronics, as well as drugstores and supermarkets. Alternatively, you can purchase batteries online—many vendors offer various products at discounted prices. 

If your hearing aid is one of the models with rechargeable batteries, your best bet is to source the specific battery charger accessory offered by your manufacturer or an approved third-party provider. 

Whichever option you choose, always let your audiologist know what kind of battery you are using. That way, they can help you get more out of every battery cycle!

Does Medicare Pay For Hearing Aid Batteries?

Medicare generally does not pay for hearing aid batteries since standard medical coverage doesn’t include these types of supplies. However, the policy might cover hearing aid battery replacements if you have a Medicare Advantage Plan. 

It’s essential to check the details of your plan so you know exactly what is included in the coverage. With hearing aid batteries needing to be changed regularly, knowing if your goal will help take care of that expense is helpful. 

For example, some plans may reimburse required hearing aid batteries once or twice a year. So, if you’re relying on hearing aids to help manage your hearing loss and budgeting for those battery changes can be difficult, it is beneficial to research whether Medicare Advantage Plans may assist with those costs.

Types Of Hearing Aid Batteries Recap

All in all, hearing aids require special batteries to operate. There are two main types of batteries for hearing aids available: rechargeable and disposable. Rechargeable hearing aids contain a lithium-ion battery that is recharged nightly for up to 24 hours. They may need replacing after about two years and cost significantly more than disposable ones. In contrast, disposable hearing aids use zinc-air button cells that come in varying sizes and can last 3-21 days, depending on the size. 

Both batteries can typically be recycled, although some facilities do not accept used hearing aid batteries. Additionally, checking with your local municipality, pharmacy, or recycling center is an excellent way to find out where you can recycle the batteries safely and sustainably. It is also essential to ensure the proper disposal of used hearing aid batteries and double-check that all safety protocols are followed. 

Lastly, although different hearing aid battery brands are available, you must consult a healthcare provider and ensure you have an appropriate fit before purchasing any hearing aid battery, as they vary by model/size/voltage/brand. 

Hopefully, you will be able to discover the kind of hearing aid battery that is best for you using this guide. Understanding the basics will set you up for success when deciding which type of power source is best for your lifestyle and needs!
