The best hearing aid batteries are batteries that ensure hearing aid users get the most out of their devices by providing maximum comfort, convenience, battery power and shelf life.

Hearing aids have undoubtedly been one of the most innovative inventions of the last century making it possible for individuals with some sort of hearing impairment to lead normal lives, free from disability. The battery-powered form makes for increased portability and comforts as they’re almost weightless and fit snuggly into your ear(s).

Hearing aid batteries are arguably one of the longest lasting batteries, at least compared to smartphone and computer batteries. Eventually, even the best batteries for hearing aids get weak or die. How do you now select the best hearing aid batteries from a sea of types and sizes?

5 Best Hearing aid Batteries: Editor Recommended

This hearing aid battery review does the work for you and makes a comprehensive list of the best rated hearing aid batteries. The batteries included here were a select few out of the numerous manufacturers and brands available, based off of results of tests carried out on all of them by professional purchasers.

Product Guide

Understanding how a product works goes a long way in deciding what product works for you. This way the decision on the type, size, manufacturers, brand would be a joint one between you and your audiologist. So, in this section we may tend to get a bit “techy” in describing how hearing aids and hearing aid batteries work, their types and sizes.

How do hearing aids work?

Hearing aid are like mini speakers within the ear. They basically receive sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier then increases the power of the signals and sends them to the ear through a speaker. Simple enough right?

What are the types of hearing aids and how does it relate to battery life?

  • The larger sized hearing aids (like the ones that are hooked around the back and into ear) generally have large batteries and are usually the longest lasting hearing aid batteries. This is because they have more physical space to accommodate larger batteries.

Larger hearing aids tend to have more features which may actually decrease the life of your battery if you’re constantly making use of all the features.

You may also have to trade in a longer battery life for comfort as the larger sized hearing aids are more bulky and heavier than the smaller options.

  • This contrasts the smaller sized hearing aids (the in-canal versions that are directly in your ear canal and lack a hook) that are typically accompanied by smaller capacity batteries due to size limitations. They are generally more comfortable.

So, size should not be the only factor you consider when discussing what hearing aid is right for you with your audiologist. Although the larger ones come with larger batteries, it may not be the one you need. Other factors such as; features you use regularly and convenience should be on your mind.

Types of Hearing Aid Batteries

Conventionally, hearing aids came with small “button” batteries that users had to change within a period of days to weeks. The current technology also features hearing aid models that run on rechargeable batteries. It is best to decide which battery types is more convenient for you.

There’s two main types of hearing aid batteries based on whether it’s rechargeable of not.

1. Rechargeable Batteries

The most modern hearing aid models come with rechargeable lithium-ion batteries. These are primarily found in the behind-the-ear style devices. Charging is mainly done during the wearers sleeping hours, so mostly at night. Popular rechargeable hearing aid manufacturers on the market include; Oticon, Starkey, Phonac, Widex.

The lifespan ranges from 3-5 years before they need replacement unlike the disposable varieties which typically last a few days. In terms of how long they last after a single charge, the range is 30-35 hours which is more than enough for a full day’s use without before the night charge.

  • Pros
    1. Easier handling
    2. Safer for kids
  • Longer shelf-life
  • Cons
    1. Not suitable for individuals with active lifestyles
    2. Additional cost
  • Fewer styles to choose from

2. Replaceable Batteries

Zinc-air button batteries (simply known as button batteries) have been around for close to a century and were the first types of hearing aid batteries to be used. They are still being used till today by some of the most popular hearing aid manufacturers like Harbor Audiology and Hearing Services.

They are called zinc-air batteries because they are activated by contact and reaction with air. A factory-sealed sticker allows them to stay “dormant” until it is taken off. As soon as it is removed, oxygen in air reacts with the zinc within the battery and “activates” it. Professionals recommend waiting a full minute after removal of the seal to let the zinc react completely before placing it in the device. Once the seal is removed, the battery remains active even if the seal is replaced until it is drained of power.

As long as the seal remains intact the zinc-air batteries can be stored for long periods of time (up to 3 years) at room temperature and a low-humidity environment. So, purchasing them in bulk is a good idea as they have prolonged shelf lives and you avoid getting stranded and having to run to the store when the one in use runs out.

  • Pros
    1. Long shelf-life
    2. Suitable for individuals always on the go
  • Cheaper than their rechargeable counterparts
  • Cons
    1. Serious choking hazard for kids
    2. Has to be replaced frequently

Seeing that both types of batteries have their pros and cons, it’s ultimately up to you the user to decide which is more suitable to your lifestyle.

Sizes of Hearing Aid Batteries

Both the rechargeable and replaceable or disposable batteries come in different sizes and when sizes are listed they can be either. Although when a person says “size 312” batteries they most likely are referring to the disposable batteries even though rechargeable size 312 batteries also exist. So, it’s best to state both size and type to avoid avoidable mishaps.

Hearing aid batteries come in different sizes depending on the size of the device- larger hearing aids come with larger batteries, the degree of hearing impairment- individuals with more severe forms of hearing loss usually need more powerful and larger batteries.

There are 5 sizes of disposable hearing aid batteries which are, in order of decreasing size include:

  1. Hearing aid Batteries Size 675 – Width: 11.6mm, Height: 5.4mm
  2. Hearing aid Batteries Size 13 – Width: 7.9mm, Height: 5.4mm
  3. Hearing aid Batteries Size 312 – Width: 7.9mm, Height: 3.6mm
  4. Hearing aid Batteries Size 10 – Width: 5.8mm, Height: 3.6mm
  5. Size 5- No longer on the market.

Estimated Battery Lives Based On Size

The battery lives on non-disposable batteries generally range from 5-14 days, given the user wears it for 15-17 hours daily. This also depends on the extra features present and the size of the batteries as smaller batteries have shorter lives than larger ones. The average lifespan of hearing aid batteries includes:

  1. Size 675 – 6 – 7 days
  2. Size 13 – 6 – 14 days
  3. Size 312 – 3 – 10 days
  4. Size 10 – 9 – 20 days

Color Coding of Disposable Batteries

Having to memorize the sizes just based off of the numbering can be cumbersome. So, a universally accepted color coding system that allocated different colored seals to different sizes was devised which makes identifying and purchasing the right size a lot easier. They include:

  1. Size 675 – Blue
  2. Size 13 – Orange
  3. Size 312 – Brown
  4. Size 10 – Yellow

 What To Look For When You Hit The Market? (Buyers Guide)

We made a pretty inclusive list of the best rated hearing aid batteries based on a bunch of already stated criteria. But, the final choice of the kind of battery to purchase for your hearing aid would depend on the kind of hearing aid you own. Once you know the manufacturer and model number of your hearing aid, look out for the following:

  • The Size of the Hearing Aid Battery

This is first on the list because it simply is the most important factor to consider when purchasing a hearing aid battery. Though uncommon due to color coding, it is not unheard of purchasing the wrong size of batteries. Always double check the size compatible with your particular hearing aid before making the purchase.

  • The Manufacturer

Although the most popular brands can produce not-so-great products and vice versa, it is best to go for the known and reputable brands like the ones included in the list above with solid warrantees and return policies.

  • The Neatness of the Hearing Aid Battery Package

Sometimes judging a book by its cover might not be the worst thing particularly when it comes to batteries. This is because batteries lose their battery and shelf life the longer they stay in warehouse storage.

To prevent this, ensure that the batteries are shipped within a maximum of 6 months after the manufacture date on the package. The expiration date should also be at least 2 years into the future.

  • The Value for Money

As you can see from the list above, hearing aid batteries usually come in packs and not in single units. Do the math to find out how much you are paying for a single unit by simply diving the price by the number of units per pack. Also try to read user reviews on battery and shelf life to ensure you’re getting maximum value for said price.

  • Mercury-free status

Modern day batteries should be mercury free by FDA standard. Ensure the manufacturer guarantees 0% mercury levels before making the purchase.

  • Convenience/ Ease of handling

This is particularly important for older hearing aid users which make up the greater percentage of individual with some form of hearing impairment. Convenience features like larger tabs make it easier to install the batteries in these individuals who make be lacking adequate manual dexterity.

Tips To Prolong The Life Span Of Your Hearing aid Batteries

Here are a few Dos and Don’ts that help you prolong the life span and get the most out of your hearing aid batteries:

  • Do
    1. Let the battery breathe for at least a minute after taking off the tab
    2. Open the battery door at night
    3. Use the oldest pack of batteries first
    4. Store in a cool, dry place
    5. Consider getting rechargeable hearing aid devices
  • Don’t
    1. Use your greasy, dirty hands to handle the batteries
    2. Take the stickers off the batteries unless you’re ready to use it
    3. Keep the batteries in the hearing aid if you won’t use it for prolonged periods of time

Conclusion

The right choice of hearing aid batteries can greatly affect the function of your hearing aid even including the sound quality produced by the device. So, it is necessary to make the right choice and select the best hearing aid batteries that have the longest shelf and battery lives, come from reliable manufacturers, are easy to use and don’t require you to break the bank to acquire.
