      Hearing Aid Batteries 

      Why are there batteries?

      Thanks to our modern age, hearing aids are becoming more powerful, more technologically advanced, and even smaller in size. As the landscape of hearing aids begins to change, so does the device requirements for power consumption and batteries size!

      At United Hearing Healthcare, we understand how complex it can be to navigate the onslaught of information about hearing aids, let alone their battery requirements. For this very reason, we have created a “one-stop shop” for everything you need to know about hearing aid batteries, sizes, lifespan, and brands!

      Sizes of Batteries

      (Hearing aids come in a variety of different sizes, styles, and different power needs. Larger hearing aids require larger batteries and smaller hearing aids require smaller batteries…you get the point! Additionally, hearing aids for people with severe or profound hearing loss typically require more power, and therefore, larger batteries.

      There are five sizes of hearing aid batteries currently available on the market. From smallest to largest: 5, 10, 312, 13 and 675. Due to the small size of the batteries, they are not often referred to by size; instead, color coding is used. From the smallest to the largest, their coordinating colors are: red, yellow, brown, orange, and blue.

      Battery Life

      Hearing aid batteries, on average, can last anywhere from 5 to 14 days based on usage and daily activity. How long each individually lasts is dependent upon the size of the battery and the amount of power needed by the hearing aid. Typically, smaller batteries have shorter battery life than larger ones. 

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

      Types of Batteries

      Nickel Metal Hydride

      A nickel metal hydride (NiMH) battery is a type of rechargeable battery found in many rechargeable hearing devices. Widely used and having been around for longer, these batteries provide reliable power for the devices you need most!

      Silver Zinc

      Silver zinc batteries may be a newer development in the world of rechargeable power sources, but that by no means counts them out! For those who travel often or have other concerns regarding being able to charge their devices frequently, silver zinc batteries can often be swapped out for a zinc air battery, enabling you to continue your activity without compromising your hearing ability!


      Trusted for use in a diverse array of devices, you may already be familiar with lithium-ion batteries! Packing a wallop of power while maintaining a small energy footprint, these rechargeable batteries can often deliver up to 24 hours of continuous use for your hearing devices!

      Zinc Air

      Zinc air button batteries are perhaps the traditional battery you think of when you think of hearing aids. These batteries are long lasting and disposable, providing convenience when a place to recharge your devices may not be available!

      Hearing Aid Leasing

      At United Hearing, we have developed a leasing program that is designed for those who are seeking an affordable alternative to the standard of spending $5-7k on hearing aids every 3-5 years. One of the major perks of our leasing program is that we make it worry-free!

      Final Thoughts

      The past ten years of hearing aid development have been characterized by significant technological progress. However, these advances have resulted in a massive increase in the level of power consumption. That means hearing aid batteries are a very important consideration, not just for manufacturers but also for hearing care professionals and consumers.

      In fact, today’s hearing aid wearers actively request environmentally friendly and hassle-free battery solutions. At United Hearing Healthcare, we meet these requests by offering rechargeable battery solutions and continuously recycle used battery components!
