Our picks for the best disposable hearing aid batteries of 2024

Duracell hearing aid batteries

Founded in 1965, Duracell is a trusted and well-known battery brand. Duracell disposable hearing aid batteries come in all four sizes in packs of eight, 12, 16, 24, and 32 and start at around $0.32 per battery (for the larger pack sizes). The batteries boast extra-long tabs for simpler handling and lightweight, easy-to-open packaging. In fact, these hearing aid batteries are recommended by the Arthritis Foundation for ease-of-use. ^[3]Procter & Gamble. Arthritis Foundation Grants Ease-Of-Use Commendation to Duracell EasyTab Hearing Aid Battery. April 9, 2008. Found on the internet at https://news.pg.com/news-releases/news-details/2008/Arthritis-Foundation-Grants-Ease-Of-Use-Commendation-to-Duracell-EasyTab-Hearing-Aid-Battery/default.aspx

These batteries have one of the longest shelf lives at four years. (Shelf life can be affected by temperatures, humidity, and other factors. Always follow tips for storage to maximize shelf life.) Duracell hearing aid batteries are easy to find at most pharmacies, grocery stores, drugstores, and online. If you’re looking for a brand you can find almost anywhere, it’s Duracell. The company has 4.6 out of 5 stars on Amazon. But these hearing aid batteries are the most expensive in our review, so we don’t recommend them for the price-conscious buyer.

Powermax hearing aid batteries

Another popular and recommended brand for hearing aid batteries is Powermax USA. The brand offers hearing aid batteries in the three most common sizes: 10, 13, and 312. While these batteries are advertised as having “extra-long tabs,” the tabs are not nearly as long as some other brands (like Duracell). Easy-to-open packaging—used for the opening and retrieval of individual batteries—is nearly identical to Duracell’s, except they are arranged in a circular pattern instead of in a row.

Compared to Duracell, these batteries have a slightly shorter shelf life of three years. They’re available in bundle options of 8, 16, or 24 packs (eight batteries per pack) and a low starting cost of $0.22 per battery. Powermax USA hearing aid batteries are not commonly available at drugstores and pharmacies but are easily found on Amazon, where they have 4.6 stars out of 5. Note: Powermax USA is the only brand of disposable batteries in our review that does not offer a 675 battery size option.

Rayovac hearing aid batteries

We also recommend Rayovac hearing aid batteries. These batteries are made in the United States, have 4.6 stars on Amazon, and start at $0.45 per battery. Rayovac packaging includes a dial dispenser similar to Powermax USA. For the 10, 13, and 312 battery sizes, the brand sells packs of eight and 16, while the 675 size comes in packs of six. Rayovak also offers extra-long tabs and easy-open packaging. These tabs are the widest in our review, making them the best for larger fingertips. Plus, you can close Rayovac packaging after opening, so it serves as a storage case. Rayovac claims the longest battery life and a four-year shelf life.

Whitleey Smith, of Batteries Plus in Denver, Colorado, told us, “We sell and recommend Rayovac for hearing aids because they last 30% longer than Duracell, are made in the USA, and the company owns Energizer.”

Panasonic hearing aid batteries

Panasonic hearing aid batteries come in packs of six in all four sizes: 10, 13, 312, and 675. They start at $0.35 per battery for 60 batteries on Amazon, and have a 4.8 star customer rating. These batteries have the smallest tabs in our review, so they may not be suitable for those with dexterity issues. The Panasonic hearing aid battery shelf life is quoted at three years. They feature a Teflon layer for optimum airflow through the battery, aimed at improving performance in a wide range of temperatures. Panasonic batteries are made in Japan. While they seem to be less popular and more difficult to find both in person and online, we think they’re the most economical battery option on the market.

Power One hearing aid batteries

Power One batteries are made in Germany, and the company promises that every single battery is tested in production. Power One batteries are the second least expensive in our lineup, starting at $0.25 per battery for 80 batteries on Amazon, where they have 4.5 out of 5 stars. Their packaging and tabs are on par with Panasonic and may not be a good choice for people with dexterity challenges.

How do hearing aid batteries work?

Hearing aid batteries provide the necessary power to hearing aids, allowing them to perform a range of complex functions, like amplification, noise reduction, and connectivity with other devices. Hearing aid batteries come in two types: disposable and rechargeable.

Disposable hearing aid batteries

Disposable batteries are designed for a single use and, once depleted, must be discarded and replaced. They come in multiple sizes to accommodate different models and styles of hearing aids. All hearing aid disposable batteries are now zinc-air type batteries, which are mercury-free. This transition was completed in 2011 in an attempt to remove toxic mercury from our products and landfills. Disposable batteries are readily available and often cheaper than rechargeable batteries when you compare the upfront cost. They can be a good choice if you live in an area with an unstable electricity supply or travel frequently, as you won’t ever have to worry about charging your hearing hearing aids.

Rechargeable hearing aid batteries

Rechargeable batteries, on the other hand, are designed to be recharged and reused, eliminating the need for frequent battery replacements. They are typically built into the hearing aids and can be charged overnight for a day’s use. Most rechargeable hearing aid batteries are lithium-ion type batteries. Rechargeable batteries are more environmentally friendly, as they generate less waste. They also save you from the inconvenience of regularly changing small batteries.

What do the different numbers mean?

Disposable hearing aid batteries come in four common sizes: 10, 13, 312, and 675. The number represents the size of the battery. Size 10 is the smallest, and size 675 is the largest. The battery size you need depends on your hearing aid model and the power it requires.

• Size 10 batteries are the smallest type, with a diameter of 5.8 millimeters and a thickness of 3.6 millimeters. They’re most commonly used for in-the-canal (ITC) and completely-in-canal (CIC) devices.
• Size 13 batteries have a 7.9-millimeter diameter and a thickness of 5.4 millimeters. They’re most commonly used in in-the-ear (ITE) and behind-the-ear (BTE) hearing aids.
• Size 312 batteries also have a diameter of 7.9 millimeters and the same 3.6-millimeter thickness as the size 10. They’re most commonly used for ITC and ITE hearing aids.
• Size 675 batteries are the largest size. They’re 11.6 millimeters in diameter and 5.4 millimeters thick. These are typically used in BTE hearing aids and cochlear implants with more complex circuitry.

What do the different colors mean?

Each battery size is also associated with a specific color to make identification easier:

• Size 10: Yellow
• Size 13: Orange
• Size 312: Brown
• Size 675: Blue

Are hearing aid batteries interchangeable?

While all hearing aid batteries work off the same basic principle, they are not interchangeable. Each battery size is designed for specific types of hearing aids, and using the wrong size could damage your device.

How to store and use disposable hearing aid batteries

For optimal performance and lifespan, hearing aid batteries should be stored in their original packaging, in a cool, dry place. Avoid storing them in hot places, like near a window or in your car, as heat can cause the batteries to lose charge. They also should not be stored in a refrigerator or freezer due to moisture. It’s also essential to keep them away from metal objects and coins to prevent short-circuiting. Always keep batteries out of reach of children and pets. ^[4]Medical Health Authority. The Ultimate Guide to Storing Your Hearing Aid Batteries: Tips and Tricks. Updated May 27, 2023. Found on the internet at https://medicalhealthauthority.com/blog/hearing-aid-battery-storage-case-tips-and-tricks/ You can purchase a hearing aid battery storage case to preserve the shelf life and quality.

Zinc-air batteries use zinc as the active material because it keeps weight to a minimum while preserving performance. Since they are oxygen-activated, after tearing off the tab, oxygen reaches the components, and they’re ready to use about a minute later. We now have evidence that waiting five minutes leads to longer battery life. ^[5]American Speech-Language-Hearing Association (ASHA). 5-Minute Rule Extends Battery Life. Aug. 1, 2015. Found on the internet at https://leader.pubs.asha.org/doi/10.1044/leader.NIB3.20082015.11 Do not pull off the tab until you are ready to use the battery.

Which type of battery is better?

The “better” type of hearing aid battery really depends on the individual user’s lifestyle, hearing aid model, and personal preferences. Each type comes with its unique set of advantages that might make it more appealing to certain users. It’s always best to consult with a hearing specialist to determine the most suitable option for you.

Disposable batteries

Disposable batteries are often praised for offering versatility and convenience. They’re available in a variety of sizes to fit almost any hearing aid, and because they’re widely available, you can find them in most grocery stores, pharmacies, or online. Users also appreciate the peace of mind that comes with having a fresh pack of batteries on hand, especially when traveling. Disposable batteries typically last three to 10 days, depending on the power demands of the hearing aid and the amount of daily use.

Rechargeable batteries

Rechargeable batteries, on the other hand, are known for their longevity and eco-friendliness. Users enjoy the ease of recharging their hearing aids overnight and not having to worry about changing batteries regularly. This is especially beneficial for people with dexterity issues or those who would rather not handle small batteries on a recurring basis. The battery generally lasts all day and has an overall lifespan of three to five years.

How much do hearing aid batteries cost?

The cost of hearing aid batteries varies depending on the type (disposable or rechargeable), brand, and where you choose to buy them.

Purchasing in bulk vs. buying as needed

Disposable hearing aid batteries typically come in packs of six to eight, but many retailers offer larger packs or bulk options that provide better value. For instance, a single pack of six batteries might cost around $5–$7, but you could find a bulk pack of 60 batteries for around $20–$30, depending on the brand and size.

Buying in bulk is generally more cost-effective, especially for those who use their hearing aids all day, every day. But because disposable batteries have a shelf-life, it’s not advisable to buy more than you can use within three to six months.

Cost of disposable batteries vs. rechargeable hearing aids

When considering the overall costs, it’s essential to note that while disposable batteries are relatively cheap, the cost can add up over time. For instance, if a hearing aid user changes batteries once a week, the yearly cost of batteries could range from $40–$70.

Rechargeable hearing aids typically cost more up front, with prices varying widely based on features and brand. But considering you won’t need to purchase batteries continuously, the long-term cost could end up being comparable, if not cheaper, especially over several years of use.

How to save money on hearing aid batteries

Given the cost of disposable hearing aid batteries, finding ways to save can provide significant financial relief. Below are several strategies to help you cut down on these costs.

Health savings accounts and flexible spending accounts

If you have a Health Savings Account (HSA) or a Flexible Spending Account (FSA), you will likely be able to use these funds to cover the cost of your hearing aid batteries. Check with your account provider to confirm what is and isn’t considered a qualified medical expense.

Medicare and other medical insurance

Original Medicare does not cover hearing aids or hearing aid batteries, but some Medicare Advantage (Part C) plans may offer benefits related to hearing aids. Also, some private insurance companies may cover a portion of the cost. Always check with your specific plan and provider.

Bulk discounts

Buying batteries in bulk can often lead to significant savings, especially if you’re a frequent user. Many online retailers, like Amazon, offer bulk discounts and “subscribe and save” discounts for signing up for repeated subscription purchases, which can save up to 15%.

Affordable providers

Price comparison is key when purchasing hearing aid batteries. Retailers such as Amazon, Costco, and Walmart typically offer competitive prices. Also, some online specialty stores focus solely on hearing aids and batteries, often offering excellent deals.

Organizations providing assistance

Organizations such as the Starkey Hearing Foundation are committed to assisting deaf and hard-of-hearing people with limited financial resources. The American Speech-Language-Hearing Association provides a comprehensive list of national support resources, and you may visit the NCOA BenefitsCheckUp page to find local support resources.

Prolonging battery life

You can also save money by extending the life of your disposable hearing aid batteries. Simple strategies, like turning off your hearing aids when not in use and storing your batteries in a cool, dry place, can help them last longer. The five-minute rule refers to letting a new battery sit for five minutes after removing the sticker tab and before placing it in the hearing aid. This allows the battery to fully oxygen-activate and can help prolong its life for up to two to three additional days.

Hearing aid companies providing batteries

Some hearing aid companies provide free batteries for a certain period or even the life of the hearing aid with purchase. Starkey and Phonak are examples of companies that have offered such promotions.

Where to buy hearing aid batteries

You can buy hearing aid batteries in many locations, both in-store and online. Here are some options and things to consider:

In-store options

• Pharmacies: National chains, like Walgreens, CVS, and Rite Aid, typically carry a variety of hearing aid battery brands and sizes. The advantage of purchasing in-store is you can easily return faulty batteries or unopened packs you no longer need.
• Big-box retailers: Stores like Walmart, Target, and Costco also stock hearing aid batteries, often at competitive prices. Costco, in particular, has its own brand (Kirkland), which is known for its affordability.
• Specialty stores: Specialty hearing aid stores or hearing centers also sell batteries, and staff can help guide you toward the right size and brand for your specific hearing aid.

Online options

• Amazon: Amazon has a wide range of hearing aid batteries from various brands. Its customer review and ratings section can be helpful when comparing brands. Remember to check the return policy before purchasing, as it may differ between sellers.
• Hearing Direct & HearStore: These are examples of online specialty stores that focus solely on hearing aids and batteries. These stores usually offer competitive prices, bulk discounts, and useful resources for hearing aid users.
• Brand websites: Many hearing aid brands sell batteries directly from the brand websites. This can be a good option if you prefer to stick with a specific brand.

Return policies

Regardless of where you choose to buy your batteries, always check the return policy before purchasing. Most retailers will allow you to return unopened battery packs, but some may also provide refunds or exchanges for batteries that didn’t meet their expected lifespan. It’s a good idea to keep your receipt in case you need to make a return or exchange.

Hearing aid battery accessories

Beyond the hearing aids themselves and the batteries they require, there are some additional accessories, which can significantly enhance the user experience.

Hearing aid battery case/caddy

Hearing aid battery cases can be a valuable tool for anyone who uses disposable-battery hearing aids. These small, compact cases are often designed to attach to your keychain and hold two batteries, ensuring you always have a backup when needed. They usually have individual compartments for each battery, which help to keep the batteries organized and prevent them from touching each other. This is important because when hearing aid batteries come into contact, they can short-circuit and lose power. Hearing aid battery cases are typically made from sturdy materials, like plastic or metal, to protect the batteries from moisture and damage. Some even feature a built-in battery tester, allowing you to check the power level of your batteries on the go. These cases are widely available and can be found in most stores that sell hearing aid batteries or online. They are relatively inexpensive ($5–$10) but can provide high value in terms of convenience and peace of mind.

Hearing aid battery tester

While some battery cases include built-in testers, standalone battery testers can be a valuable tool. They allow you to quickly check the power level of your batteries, which helps you avoid unexpected hearing aid shutdowns. They also commonly attach to a keychain and cost $5–$10.

Hearing aid battery magnet tool

Handling small hearing aid batteries can be tricky, especially for those with dexterity issues or vision impairment. A hearing aid battery magnet is a tool designed to make this process easier. These magnets can help you pick up, hold, and insert the tiny batteries into your hearing aid. Cost ranges from around $6–$20.

Tips before you decide on a hearing aid that uses disposable batteries vs one that uses rechargeable

Choosing between disposable and rechargeable hearing aid batteries often comes down to your personal lifestyle and specific needs. Here are some factors to consider before making a decision:

Power supply

If you live in an area prone to power outages or you frequently travel to places where a consistent supply of electricity can be a challenge, disposable batteries might be a better option. They can be used immediately after purchase, without the need for an initial charge, and are readily available in most convenience stores and online.

Travel frequency

Frequent travelers might find disposable batteries more convenient as they’re lightweight and easy to pack—you also don’t need to carry a charger or worry about finding a power outlet. But if you’re traveling to remote areas where it might be challenging to find replacement batteries, rechargeable batteries could be a better option, provided you have a reliable way to charge them.

Daily usage

For individuals who use their hearing aids for extended periods each day or have high-power-demanding settings, rechargeable batteries may be beneficial. Modern rechargeable hearing aids can typically deliver 24 hours of use with a single three- or four-hour charge.

Handling capabilities

Rechargeable batteries require less handling because they stay in the hearing aids, which can be beneficial for people with dexterity issues, arthritis, or visual impairment. Disposable batteries, on the other hand, are small, can be tricky to handle, and require frequent changes.

Environmental impact

Rechargeable batteries are more environmentally friendly than disposable ones, as they result in less waste. If environmental considerations are essential to you, rechargeable batteries might be your preferred choice.

Cost considerations

While hearing aids with rechargeable batteries often have a higher upfront cost, they can potentially save you money in the long run because you won’t be continuously buying replacement batteries.

What is the correct way to dispose of used hearing aid batteries?

Used hearing aid batteries, whether disposable or rechargeable, should be disposed of properly to minimize environmental impact. Here’s a step-by-step guide on how to do it:

#1 Recycle: Recycle whenever possible. Options include:

• Local recycling programs: Check with your local waste and recycling facilities to see if they accept used batteries. Some facilities have special programs for battery recycling. You can often find these facilities by searching online for “battery recycling near me.”
• Retailer programs: Some retailers, such as electronics stores or hearing aid providers, offer in-store recycling programs for used batteries. These programs can be a convenient way to dispose of your batteries when you’re out shopping.
• Special battery recycling programs: You may have access to mail-in programs that will recycle batteries. Battery manufacturers, environmental organizations, and some hearing aid manufacturers offer these programs. You typically have to package and mail your used batteries.

#2 Safe disposal: If you can’t recycle your batteries, and need to dispose of them in the regular trash, make sure to follow safety guidelines. For instance, place tape over the battery terminals to prevent any residual charge from causing sparks in the garbage truck or landfill.

#3 Never incinerate: Never attempt to incinerate used batteries. This can cause the batteries to explode, leading to potential injury and environmental harm.

Bottom line

The world of hearing aid batteries is vast, with multiple factors, like cost, lifespan, and rechargeability, influencing what might be the best option for you. Both disposable and rechargeable batteries have their pros and cons, and their suitability depends largely on individual needs and lifestyle. Rechargeable batteries are convenient, reducing the frequency of replacements and providing a green solution. Though they might require a larger upfront investment, their longevity often makes them cost-effective in the long run.

Disposable batteries, on the other hand, are economical and easy to find, but they do require frequent changing and can pose an environmental challenge. Buying them in bulk and proper storage can help prolong their life and save on costs. We recommend Duracell for reliability and availability, Powermax USA for affordability, Rayovac for ease-of-use (especially when dexterity is a concern), Panasonic for a widely available mid-priced option, and Power One for affordability and reliability.
