Understanding Hearing Aid Batteries

Hearing aid batteries come in four common sizes: 10, 13, 312, and 675. Each size has its own average lifespan. According to the Australian Government’s Department of Health, over 20% of Australians could benefit from using hearing aids, and knowing the battery lifespan can significantly impact the efficiency of these devices.
  • Size 10 (Yellow): Last for 3-7 days
  • Size 13 (Orange): Last for 6-14 days
  • Size 312 (Brown): Last for 3-10 days
  • Size 675 (Blue): Last for 9-20 days
These durations are averages and may vary based on factors discussed in the next section.

Factors Affecting Battery Life

Several factors can influence the longevity of your hearing aid batteries. By understanding these, you can enhance the life of your hearing aid batteries, which is an essential aspect of hearing aid maintenance.
  • Hearing Aid Type: Different models require different battery sizes. Generally, larger devices require larger batteries, which tend to last longer.
  • Usage: The more frequently you use your hearing aid, the shorter the battery lifespan. Daily use, volume level, and even the type of sounds you listen to can affect battery life.
  • Environment: Batteries tend to drain faster in hot, humid environments. Keep your hearing aids in a cool, dry place when not in use.
  • Storage: Incorrect storage can shorten battery life. Always store batteries at room temperature, and never refrigerate them.

Extending the Life of Hearing Aid Batteries

Here at Audi Hearing, we want to ensure you get the most out of your hearing aid batteries. Following are some simple tips to help maximise battery lifespan.
  • Turn off your hearing aids when not in use.
  • Keep the battery compartment open overnight to let moisture escape.
  • Remove the batteries if you won’t be using your hearing aids for an extended period.
  • Store your batteries properly.

The Role of Technology in Hearing Aid Batteries

Over the years, technological advancements have significantly improved the lifespan of hearing aid batteries. Take, for example, the rise of digital hearing aids. These little marvels are not just a technological triumph, but they’re also champions of energy efficiency, giving your batteries a big leg-up in the longevity department. Moreover, the development of rechargeable hearing aids, such as those offered at Audi Hearing, means you no longer need to worry about frequently changing batteries. Rather, you have the convenience of recharging your device akin to how you power up your mobile phone or laptop. This approach not only simplifies the usage of hearing aids but also aligns with a more eco-conscious lifestyle, making a small yet significant contribution to our planet.

The Importance of Quality Batteries

Another crucial aspect to ponder upon is the intrinsic quality of the batteries. You see, not all batteries are born equal. While it may seem insignificant, choosing to spend a bit more on superior quality batteries can make a notable difference. This seemingly modest investment can work wonders in extending the life of your batteries. Ultimately, it’s about squeezing every drop of value from your hearing aids, making sure they serve as your reliable connection to the vibrant world around you for as long as possible. At Audi Hearing, we offer a range of high-quality batteries that are designed to provide consistent power and longer life. They also reduce the risk of damage to your hearing aids caused by battery leakage, which can be an issue with cheaper batteries.

A Word on Battery Safety

While chatting about batteries, it’s of paramount importance to acknowledge the potential safety risks associated with their size. Hearing aid batteries, due to their petite size, can pose a significant choking hazard, especially to inquisitive little ones and curious pets. Taking heed from the Australian Competition & Consumer Commission, it’s highly recommended to always stow your batteries somewhere that’s beyond the reach of children and pets. And when the time comes to part ways with your old batteries, it’s crucial to send them off responsibly. It’s about taking that extra step to make sure they’re disposed of properly, keeping safety front and centre for everyone involved. Moreover, swallowing a battery can lead to serious health complications. If you even remotely suspect that a battery has been swallowed, time is of the essence. It’s absolutely crucial to reach out for immediate medical assistance without any delay. Above all else, your safety and well-being take precedence. If there is any suspicion of a battery being swallowed, it is imperative to seek immediate professional assistance. Don’t hesitate to reach out for the necessary help to ensure your health is safeguarded. For further information or guidance, you can look towards the Australian Government’s Poisons Information Centre, which serves as a valuable resource in such situations.

Recycling Your Hearing Aid Batteries

When it comes to disposing of used hearing aid batteries, it’s essential to remember that they should not be thrown in the regular trash. Batteries contain harmful chemicals that can be damaging to the environment. Instead, you should take your used batteries to a recycling facility. Many local councils, retail outlets, and of course, our Audi Hearing centres offer battery recycling services.
