5 Tips to Extend the Battery Life of Your Hearing Aids


Give Your Hearing Aid Batteries a Longer Lifespan

Hearing aid battery life directly impacts your hearing aids’ efficiency. These devices are life-changing and wearers know that when they hear that little beeping noise, they need to have a spare pack of batteries handy. 

Our team of Manhattan audiologists at Audio Help knows how important your hearing devices are to your overall wellness. To help you enjoy the most efficient hearing experience possible, we’ve compiled this simple guide for extending the life of your hearing aid batteries. 

How Long Do Hearing Aid Batteries Last? 

A standard hearing aid battery’s lifespan varies depending on a few factors. On average, it will hold a charge between 3 and 7 days. 

Some factors that affect a hearing aid battery’s lifespan include: 

  • Size of the battery 
  • Type of battery used 
  • Hearing aid use frequency 
  • Use of hearing aid’s auxiliary features
  • Exposure to extreme hot or cold temperatures
  • Exposure to excessive moisture

How to Extend Hearing Aid Battery Life

There are a few simple steps that you can take to improve the battery life of your hearing aid. Putting them into practice will help ensure that you are changing batteries less frequently and saving on replacement costs. 

Here are 5 easy tips to keep your batteries running at peak efficiency for longer: 


1: Follow the “5-minute rule” after you remove the plastic tab. 

The plastic tab found in new hearing aid batteries prevents them from using their power prematurely. When you take the plastic tab off, the zinc in the battery mixes with the air to provide energy for your device. 

Studies show that waiting five minutes before inserting the batteries into your hearing aid can extend the battery’s life by up to 3 days. Rather than draining power from the battery immediately, the zinc and air can blend to more appropriate levels for efficient use. 


2: Keep your hearing aids cool and dry.

Extreme temperatures and high humidity reduce the lifespan of your hearing aid batteries. As much as possible, try to store them in dry, temperate environments. 

Here are some tips for keeping your hearing aids cool and dry: 

  • Do not store hearing aids in extreme temperatures
  • Do not store hearing aids in high-moisture rooms like the bathroom 
  • Keep your battery door open at night in case any moisture was trapped during the day


3: Turn off your hearing aids when not in use.

Keeping your hearing aids on when not using them is a major preventable cause of premature battery drainage. When you are not using your hearing aids, such as when you are sleeping, make sure that they are turned off. 


4: Use a dehumidifier.

Dehumidifiers and dry storage kits protect both your hearing aid batteries and the devices themselves. They also provide a safe place to store your hearing aids when you take them out. This extra layer of moisture damage prevention can give your batteries a chance to breathe. 

People living in humid environments should especially consider getting a dehumidifier to protect their hearing aid batteries. These spaces can expose your hearing aids to excess moisture on a daily basis and can also potentially damage spare loose batteries you might have on hand. 


5: Use your oldest package of hearing aid batteries first.

While hearing aid batteries can be safely stored for some time, it’s a good idea to use your oldest package first. The longer the batteries sit in storage, the shorter their life will be. Like any other battery, ones for hearing aids can lose their effectiveness if left unused for a long period of time.
