5 Proven Tips to Make Hearing Aid Batteries Last Longer [CC]

Common manufacturers of non-rechargeable hearing aid batteries include Rayovac and Energizer. However, many hearing aid manufacturers sell batteries wholesale to hearing care professionals, and the batteries may carry the brand name of that hearing aid manufacturer.

Another common practice is private labeling of batteries. This means the hearing care professional may purchase batteries wholesale and have them labeled with the name, address, phone number and logo associated with their office.

Regardless of the branding, most hearing aid batteries are made by trusted companies that produce other types of batteries for all types of electronics.

Types Of Hearing Aid Batteries

All hearing aids require batteries in order to operate. The batteries you will need will depend on the type of hearing aid you have. Different types of hearing aids require different sized batteries. The most common sized hearing aid batteries are 675, 13, 312 and 10, which are all colour coded to make it easier to identify their size.

Hearing aid batteries are zinc-air operated. This is because in order to activate them, you need to remove their colour-coded factory-sealed sticker to allow oxygen to interact with the battery to turn it on. The sticker cannot be put back onto the battery to turn it off. Once it is removed, the battery remains turned on until its power is drained.

Larger hearing aids such as behind-the-ear models require larger batteries, whereas more miniature hearing aids such as completely-in-the-canal models need smaller batteries. This table shows which battery size, dimension and colour you will need for your particular hearing aid type.

Its most cost effective to buy your hearing aid batteries in a larger pack to decrease their individual price. Its worth remembering when you are budgeting for your hearing aid batteries that the smaller they are, the more frequently they will need to be replaced in comparison to larger batteries.

How Do I Know Which Batteries I Need Fo My Hearing Aid

Hearing aid batteries come in standard sizes – no matter which make of hearing aid you have it will use one of the industry-standard battery sizes. To make things easier to remember, batteries are color-coded, the ones on sale here are ORANGE, also known as size 13.

If you are not sure which size you need check the packet/card that your current batteries came in, the packaging will clearly show the colour. If you do not have a packet/card then you may have a battery with the “tab” still on, which will also be colored for the size. No packaging and no tab on your battery? Look closely at the battery itself, printed on one side will be the size of the battery – the text will be quite small to read. Once you’ve found the size of your battery use the chart below to determine the color you need:

Our survey also asked participants about which hearing aid brands they use. As you can see Widex, Oticon, and Starkey were the highest rated on this measure. However we do want to draw attention to the fact that our sample size is likely too small to draw any firm conclusions from. Another factor is wireless streaming, and this may differ from brand to brand.

Tips For Rechargeable Aids

  • Some chargers are portable which means they hold approximately three days worth of charge in the charging unit itself. Perfect solution for weekend getaways
  • If you forget to recharge overnight, rechargeable hearing aids only need approximately 30 minutes of top up charge to get you an extra three hours of wearing time
  • Rechargeable hearing aids offer you the convenience of not having to change batteries meaning they are a more environmentally friendly solution.

How Long Do Batteries Last

There are many variables that determine how long your battery will power your hearing aids.

A standard zinc-air battery lasts anywhere from three to 22 days, depending upon the type of hearing aid, the capacity of the battery, and the amount of hearing aid use throughout each day. The smallest hearing aid batteries, used for 12 to 16 hours per day, may need to be changed every three or four days, while the largest hearing aid batteries used for only a couple hours each day may go several weeks without needing to be changed.

To minimize battery drain, turn off the hearing aid when its not in use. Opening the battery door is also an option, and a good way to dry out accumulated moisture. But if the hearing aids wont be used for an extended period of time , removing the battery entirely is the best method.

These Figures Are Not That Useful

First, the study was published in 2013. While zinc-air technology has not moved on that much, changes in manufacturing processes and chemistry can have a significant difference to the end result. Even something as simple as a change in factory something that is quite common in the business world can yield significantly different results. So the figures may well have moved on since then.

More significantly, the study itself was limited. It was restricted by geographical location, so only batteries available in Brazil were tested, and the laboratory was not strictly temperature and humidity controlled, so there were significant fluctuations on a day-to-day basis. This is relevant because zinc-air batteries rely on absorbing oxygen from the air to create a current. Humidity, in particular, can significantly affect batteries efficiency.

Even worse, the study only tested two batteries for each set of figures, and they were from the same batch. This means that individual performance was being tested, not the overall manufacturing performance of each battery. Creating a suitably rigorous study should involve 20 or 30 batteries, at the very least, all from different batches.

There are two basic categories of batteries that power most auditory aid devices today, and those are replaceable and rechargeable.

The advantage of rechargeable options is that you dont have to keep buying more for your auditory aid, and the advantage of replaceable options is that you are not obliged to go through the process of recharging them when they run low.

Its often a matter of personal preference as to which type you prefer, and the discussion below will consider how long each of these two types can be expected to last.

How Can I Extend The Lifespan Of My Hearing Aid Batteries

Unfortunately there is no way to extend the lifespan of your hearing aid batteries, but you can make sure that no power is wasted by following these simple tips:

  • Always turn off your hearing aids when they are not being used and open the battery compartment door to allow any build-up of moisture to evaporate.
  • Store your batteries at room temperature, and keep them away from humid environments as this can shorten the battery life.
  • Dont put your hearing aid batteries in contact with any other metal objects like your house keys or loose change as there is a chance they could short-circuit the batteries.

Unused hearing aid batteries will typically remain charged for up to three years if kept in a dry environment at room temperature.

Where To Purchase Hearing Aid Batteries

Batteries are typically available in mass retail stores, pharmacies, grocery stores, electronics stores and through online retailers.

You might also choose to purchase batteries through a hearing aid center near you. Because hearing care providers go through their stock of batteries quickly, many wearers feel they are getting fresher batteries. Also, if you forget what battery size you need for your particular device, the hearing healthcare professional will ensure you are purchasing the correct one.

Additionally, its worth asking if your hearing health practitioner offers any kind of battery club or discount program. These programs can save you money on your battery purchases and, in some cases, you can request the batteries be sent directly to you saving you a trip to the office.

Why Is My Hearing Aid Not Working After Inserting A New Battery

If your new battery is not working after being inserted into your hearing aid, there could be a few reasons as to why. Here are four common issues to check:

  • The battery might have been inserted too quickly after removing the factory-sealed sticker. Its worth waiting a minute once peeling off the sticker to allow the battery time to activate before fitting it into your hearing aid.
  • The battery is dead. Very rarely batteries can be bought faulty. Alternatively, make sure you have replaced a new battery and not mixed it up with an old, used one.
  • Dented battery. This damage to the batterys surface could affect the contact it has with the hearing aid.
  • The battery is the wrong size. Always make sure you have the correct battery size for your type of hearing aid.
  • The battery has not been stored in the correct conditions. Make sure you keep your batteries at room temperature, away from any moisture or metal.
  • If problems persist and your hearing aid batteries continue to not operate, you should contact your hearing aid provider for further advice.


    After my first contact I was quickly called and politely dealt with. I’m very happy with the customer care received from your staff.

    Secrets To Making Your Hearing Aid Batteries Last

    How Long Do Hearing Aid Batteries Last?

    How can you make your hearing aid batteries last longer? Here are a few tips and tricks.

    Ever notice how hearing aid batteries seem to die just when you need them the most? Hearing aid batteries can drain faster depending on how often you use them, whether you use them for streaming or constant noise or if you live at a high elevation.

    In theory, a typical hearing aid battery could get over 100 hours. But in the real world, you can get anywhere from 3-22 days out of a battery depending on whether you use advanced functions that take more energy or follow certain maintenance methods and precautions that impact battery life.

    Some of this extra battery drain is completely worth it. When youre celebrating your birthday with the family in a noisy restaurant, you want to be able to hear every word. Isnt that worth an extra 10 cents?

    But in other cases, you may be draining your batteries for no reason unaware that its even happening. Its important to have a little background on your hearing aid batteries so you can understand what theyre capable of and what causes them to die a little faster on you.

    Hearing Aids With Replaceable Batteries

    In a recent broad laboratory test conducted on several of the most popular brands of replaceable power cells, it was determined which ones had the longest battery life, and continued performing at a high level the longest. Power cell sizes are different between auditory aid devices, and these sizes beginning with the largest and proceeding to the smallest size, are 675, 13, 312, 10, and 5.

    These are found in most of todays best and most capable aids, including those offered by Harbor Audiology & Hearing Services.

    For the larger 675, the top performer was the Duracell, and for the size 13, the leader was a battery manufactured by Renata. Duracells was again the best performer in the 312 size tested, and the longest-lasting size 10 was made by Rayovac.

    Some manufacturers, like the Duracell size 13 battery, are made available to the public in value size packages which might contain as many as 80, and should last for at least several months before needing replenishment.

    Other options come with an EasyTab, which allows for easy replacement, for those who have limited hand dexterity or mobility. Some like the Duracell size 10 battery, are also sold in a protective case which will keep them from becoming loose and getting lost somehow.

    Others, such as the Rayovac 312, also come with a shelf life of several years, so they can be safely stored for a long period of time before being used.

    What These Figures Do Tell Us

    These figures do tell us that manufacturers figures are not consistent, and thats primarily down to the ways in which battery life can be tested.

    Essentially, manufacturers can make up any testing method that correspond as closely as possible to the performance results as experienced by consumers when using the product in practice. This is according to Annex G of IEC 60086-1. The only stipulation is that the results must be reproducible and that they should be useful to consumers.

    Given that the power draw between different hearing aids can vary wildly, manufacturers can essentially use any reasonable power draw conditions to paint their products in the best light possible. In addition, there is no requirement that they use the same methodology across each type of battery.

    The result is a huge discrepancy.
