How Long Should Hearing Aid Batteries Last

How long should hearing aid batteries last? What determines a battery’s lifespan? Is there a difference in the type and brand of battery? In their publication Important Battery Facts for Todays Hearing Instruments,The Hearing Review details five factors that impact how long a hearing aid battery will last:

  • Severity of hearing loss
  • The degree of hearing loss will determine the level of amplification an audiologist programs into the hearing aid. The level of amplification will increase the amount of power needed to ensure the hearing aid functions properly. This directly impacts how much battery life is consumed to power the hearing instrument.
  • How many hours per day the individual uses the hearing instrument
  • The length of time the hearing aid is worn each day directly impacts the amount of battery life that is consumed.
  • The size of the battery
  • Larger batteries have a longer life than smaller batteries. Smaller batteries have less “ingredients” to power the device. Therefore, smaller batteries typically have a shorter lifespan than larger batteries.
  • Unique Features
  • Environment
  • Low Humidity
  • Less humid environments can cause batteries to dry out more quickly and therefore shorten their life cycle.
  • High Humidity
  • More humid environments can cause the battery to take on more moisture. This can also reduce its lifespan.
  • Temperature

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

    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.

    Hearing Aid Battery Safety

    Hearing aid batteries do have a potential for risk. Here are some tips to keep you and your loved ones safe:

    • Store them in a safe place: Batteries contain many compounds that can be dangerous if ingested. Protect your pets, children or grandchildren from these dangers by keeping batteries out of reach and in a safe place. You should also keep them away from medications, as they may be easy to confuse with pills.
    • Dispose of the batteries safely: Because batteries can be dangerous, its important to dispose of them in a way that doesnt put others at risk. Most audiologists offer free recycling programs where they recycle batteries safely.
    • Never place them in your mouth: While you might be tempted to hold a battery in your mouth if your hands are occupied, thats not a good idea. Likewise, young children shouldnt have access to batteries for this reason.

    Hearing Aid Battery Life

    Generally speaking, the bigger the battery, the longer it can power your device. However, your usage will affect the amount of use you get from your batteries. For instance, if your hearing aid has a lot of additional features, like Bluetooth, it will likely drain power faster.

    Disposable batteries can remain viable for about three years if you dont peel off the sticker that keeps them away from oxygen. However, once theyre exposed to the air, these batteries begin to lose charge.

    While disposable hearing aid batteries may not last long, theyre fairly easy to take out and replace, so the process becomes routine pretty quickly. If you or your loved one has limited manual dexterity, a rechargeable battery may be a better choice, though. Plugging in a rechargeable battery should require less fiddling than replacing tiny batteries.

    Rechargeable batteries can remain viable for up to five years, but the amount of use you can get before needing a recharge is often model-dependent. If youre shopping for a hearing aid with a rechargeable battery, look for a model that can run all day and fully recharge overnight.

    I’ve been using rechargeable batteries for several years for patients with dexterity issues. ;For the most part this has been very successful. ;I’ve found that in most cases the batteries must be changed about every year to 18 months. ;What happens is after multiple chargings, the battery tends to decrease in it’s the ability to stay charged. ;This results;in the hearing aids losing power prior to a full day’s use. ;When this time period becomes unacceptable, it’s time to replace the batteries. When using NiMh batteries, I always fit size 13 as that starts with about 22 hrs initially. 312 NiMh start with about 15 hrs initially therefore have to be replaced more frequently. ;Recently, there has been Lithium Ion 312 batteries released that have considerable longevity, lasting 30+ hours on a single charge and 18-24 months;replacement cycles. ;So far, these newer batteries are performing nicely and I encourage anyone not wanting to change standard batteries to research this new technology.

    Hearing Aid Battery Drain

    Hearing aid batteries you should know

    All the manufacturers have given all the required information about their hearing device battery usage. In the survey mentioned above, as an example, it is shown that Resound datasheet for the Resound LiNX2 LS61 provided information about the hearing device which uses 312 battery drains 1.3 milli-Amps from the hearing device battery, which when tested in test mode through the;ANSI S3.22 standard.

    Using the battery life formula, estimated the battery life of size 312 hearing aid which has a capacity of 145;milli-Amp-hours which is 111 hours.

    In the survey, the average receiver-in-canal hearing machine user reports total use- time per battery of 82 hours. An expected 6.3 days of battery life is calculated by considering the hearing aid user report time of 13 hours per day and which when compared with Resounds datasheet. It is found that;the datasheet suggests 8.5 days per battery usage by the user.

    So, there is a difference between the survey estimates by the hearing device and the hearing aid manufacturer datasheet.

    The problem with calculating these estimates

    There is a difference because it is difficult to find the estimates using the battery current drain. Usually, hearing machines are kept in test mode while calculating the current drain which results in disabling the advanced processing technologies such as;digital noise reduction, wireless connectivity, and;feedback cancellation.
