Battery Life For Hearing Aid Batteries

Non-rechargeable hearing aid batteries can last anywhere from five to 14 days, based on a 16-hour day of wear. This is dependent upon the size of the battery and power needed by the hearing aid. Typically, smaller batteries have shorter battery life than larger ones.

The average lifespan of hearing aid batteries is as follows:

  • Size 10 – three to seven days
  • Size 312 – three to 10 days
  • Size 13 – six to 14 days
  • Size 675 – nine to 20 days

If you are experiencing shortened battery life, there may be an issue with the hearing device. In this case, you should consult your user manual or contact your hearing healthcare professional to make sure everything is working properly.

Different Sizes Of Hearing Aid Batteries

Hearing aid batteries typically come in 4 basic designations of sizes. The difference between different models of hearing aid batteries come from their physical size as well as the power and output of the battery. The 4 main sizes of hearing aid batteries are Size 10, Size 13, Size 312, and Size 675. Hearing aid batteries are conveniently color coded in order to easily identify the size of the battery.

Hearing Aid Batteries Size 10:

Size 10 hearing aid batteries are identifiable by their yellow colored tab. The size 10 battery is a button cell type battery with physical dimensions of a diameter of 5.8 MM and a height of 3.6 MM. The overall power and discharge of the battery depends on the composition of the chemistry of the battery. Hearing aid batteries from different manufacturers will yield varying prices as well as performance.

The voltage output of these batteries is 1.45 volt and as per the company, they are the worlds longest lasting batteries.


  • 312 batteries available in a pack of 60 or in pack of 240.
  • Made in the USA and hence the quality is quite good.
  • The battery has an expiry of 3 to 4 years and hence you need not worry about the spoilage.


  • Some people reported an issue with the voltage.

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.

Pros & Cons Of Rechargeable Batteries

Rechargeable batteries have plenty going in their favor. Charging the batteries is as simple as docking the hearing aids every night, and theres no need to regularly replace batteries. People who struggle to replace disposable button batteries due to physical limitations may find that rechargeable hearing aid batteries make life much easier. Built-in batteries also eliminate the risk of accidentally ingesting batteries, so theyre a good choice for young children.

Thats not to say there arent drawbacks to rechargeable hearing aids:

  • The size of rechargeable batteries currently limits their use to behind-the-ear and receiver-in-canal hearing aids, limiting your choice of hearing aid models.
  • Recharging lithium batteries can take time, which is why rechargeable hearing aids are usually charged at night. There are some rechargeable models that offer a fast-charge option, which takes only 30 minutes to give the battery an extra four hours of life. Very active people may prefer the convenience of being able to replace disposable batteries on the go. Power outages or accidentally turning the charging dock off can also interfere with recharging.
  • When rechargeable batteries do need replacing, they must be replaced by someone with proper training, which can leave you with a loaner aid for a few days. While infrequent, such incidents should be considered when choosing between rechargeable and disposable hearing aid batteries.
  • Why Is Battery Life Important

    How Long Will Size 312 Hearing Aid Batteries Last

    Hearing aid batteries 312 size will usually last three to 10 days, or an estimated charge of 175 hours. The brand of battery, device, amount of time it is worn, amplification, and environmental factors can all play a role in how long your batteries will last. If your battery life is noticeably and consistently low, the culprit is more likely to be the device and/or usage rather than the battery itself.

    These Figures Are Not That Useful

    Hearing Aid Maintenance: How to Change a Size 312 Battery

    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.

    Can You Use A Hearing Aid Battery Past Its Printed Expiration Date

    You can use a hearing aid battery after it expired however you should not expect to get the length of time out of the battery as one that is freshly made. For example, if you typically get 7 days of use out of each zinc-air battery that you use, after it has expired by 6 months you might get the full life of 7 days or possibly get half .

    If it expired a few years ago you may get a full life or it could be completely dead as soon as it is removed from the package. So if you are going to run the risk of using an expired battery, it would be wise to have a spare set of fresh batteries on hand in case your battery unexpectedly dies.

    Hearing Aid Batteries Size 312 (brown)

    How long should hearing aid batteries last? What determines a batterys 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
