Hearing Aid Batteries

Hearing devices can be life-changing, but they can’t help you if the hearing aid batteries are dead. Hearing device users know when they hear that little beeping noise, they’d better have a spare pack of batteries handy.

Hearing aid batteries typically last between 3-7 days, depending on factors like:

  • The type and size of hearing device you have
  • The type and size of the battery
  • The number of hours per day you’re using your device
  • The technology level of the device
  • The environmental requirements placed upon the hearing devices to process sound
  • The shipping and storage of a battery before you purchase it


Luckily, there are several best practices to keep hearing aid batteries well-maintained and help them last as long as possible.

  • Always use your oldest package of hearing aid batteries first.  

Although hearing aid batteries can be stored for quite a while, the longer the batteries sit in storage, the shorter their life will be. If you always use the oldest package first, your spare batteries will never get too old.

  • Store extra hearing device batteries in a dry, room temperature place. NEVER refrigerate them!

Extreme temperatures—both hot and cold—and high humidity levels are not good for the life of your hearing device batteries.

  • Don’t remove the plastic tab from each pack’s battery until you’re ready to use it.

This plastic tab keeps the battery fresh while it’s in storage, and as soon as you take it off, the battery is activated. It will start to lose its “juice” once removed and  replacing the sticker won’t save the battery.


  • Wash your hands before replacing your hearing aid battery.

Grease and dirt on your hands can be transferred to the battery, which could affect the lifespan of the battery.

  • Let the battery sit out for five full minutes after you remove the plastic tab.

When you take the plastic tab off, the zinc in the battery mixes with the air to power it up. It is unclear why,  but recent research has shown that if you wait five whole minutes, you can extend the battery’s life by as much as 2-3 days.

  • Leave the battery compartment open when you’re not using your devices.

Whenever you’re not using your hearing aid, turn it off, put it somewhere safe and dry (don’t leave it on the bathroom counter while you shower!), and leave the battery door open. This allows excess moisture to escape and reduces the drain on the battery. It also keeps the battery from corroding, which is not good for the hearing devices.

  • Remove the batteries entirely if you won’t be using the device for an extended period of time.

This also helps to avoid corrosion and damage from trapped moisture.

Rechargeable Hearing Aids

Rechargeable Hearing Aids

Wouldn’t it be great if instead of replacing batteries every week in hearing devices, there were rechargeable hearing aids ?  Well, that is exactly what is available today.

While hearing aid technology markets advances and exciting new features and capabilities every year that more often than fall short of expectations, there has been innovation in one area, and that’s rechargeable hearing aids. If not having to buy disposable batteries frequently and handling those tiny batteries each day sounds appealing, rechargeable hearing aids might be just what you need.

ZPower Rechargeable System

In the last few years, a company named ZPower is a game-changing creator of the ZPower Rechargeable System. This innovative and award-winning system turns compatible hearing aids into rechargeable hearing aids. The system can be ordered at the time of a new hearing aid purchase or, if the hearing aids are compatible, it can be retrofit on existing devices. This system is ideal to those individuals who struggle with the following pitfalls with traditional hearing device batteries:

  • Dexterity issues
  • Vision loss
  • Environmentally conscious and want to reduce the number of disposable batteries that end up in landfills.
  • Inconvenient to repeatedly purchase batteries every several months

Rechargeable hearing aids are convenient, easy to use and environmentally-friendly.


The downside is that the ZPower rechargeable hearing aid system is not exactly cheap.  The cost of the unit is approximately $200-$300, and the rechargeable battery, which needs to be replaced every year, is approximately $50 per hearing device. Compare this to traditional hearing aid batteries which can be purchased for as little as 25 cents apiece, resulting in an annual cost of $50-$75 for a pair of devices.

Extending Hearing Aid Battery Life

Extending Hearing Aid Battery Life

Hearing aid battery life is approximately 7 days. Historically, this depends on several factors:

  • The size of the hearing aid device and size of the battery. The smallest hearing devices use a size 10 battery, which is the smallest sized battery available. The largest hearing devices for severe to profound hearing impairments, use a size 375 battery which can last 10-14 days.
  • The degree of hearing loss. If a hearing device is adjusted to the maximum levels, it will drain the battery faster.
  • The environment the user is in while wearing the hearing device. Hearing devices process and analyze tens of thousands of incoming sounds in milliseconds. This requires a lot of power from the battery. If a user is in an environment where a lot of sound and noise is present as opposed to one who is a home alone without any extraneous noise, that battery while drain more quickly.
  • Squealing. If a hearing device is not fitting in the ear appropriately, sound can leak out and squeal, a term in the hearing industry named feedback. Feedback significantly reduces hearing aid battery life.
  • Poor storage. If a hearing aid battery is stored in an environment that is much too cold (refrigerator) or too warm (near a heater or in the sun), the chemical processes inside the battery can become altered, leading to poorer battery life.


Although hearing aid batteries are typically not expensive (they can be purchased online or at big box warehouses like Costco for as little as 25 cents/battery when purchased in larger lots sizes of 100 batteries or more), it is inconvenient to have to change them approximately once a week.

Recent Discovery

Although some hearing aid manufacturers have recommended users wait 5 minutes after pulling off the sticker of hearing aid batteries to make them last longer for several years now, no one has studied the effects of this recommendation….until now. 8th grade student Ethan Manuell, a hearing aid user since the age of 4, studied the effect wait time has on the performance of hearing aid batteries for a school science project. What he found was that the optimum time between pulling the sticker off a hearing aid battery and actually using it in hearing aids was 5 minutes, which lead to batteries lasting 2-3 days longer. If one uses the average of 7 days for the life of a hearing aid battery, waiting the extra 5 minutes after pulling off the sticker could improve hearing aid battery life by as much as 43%.

Because of his discovery that led to extending hearing aid battery life, Ethan has won several awards for his experiment, including earning a US Naval Science Award.
