Dos and Don'ts for Hearing Aid Batteries

Woman with Hearing Aid

When you're prescribed hearing aids, your audiologist will give you guidance on how to clean and maintain them. As well as taking care of your hearing aids as a whole, you'll need to give some thought to their batteries too.

Although there is a wide array of hearing aids on the market, the majority still run on zinc-air button disposable batteries. While you should always follow your audiologist's instructions, there are some commons dos and don't when it comes to carrying for zinc-air button disposable hearing aid batteries:


Choose the right size

This may sound obvious, but using the right size battery in your hearing aids is vital. If you're unsure, ask for assistance so that you get the size you need. Trying to use an alternative size could be dangerous and may cause irreparable damage to your hearing aids. Fortunately, most hearing aid batteries are color-coded, so you should find it relatively easy to locate the appropriate size and shape.

Store them at room temperature

Hearing aid batteries usually last for around three years at room temperature, so you can have a small stock at home without worrying about them expiring. Keeping spare hearing aid batteries means you'll always have something to use if your existing batteries run out or are lost.

Remove the activation sticker

Zinc-air button batteries are activated when they come into contact with air. To extend their lifespan, manufacturers place a clear sticker over part of the battery. Before use, this should be removed so that the air activates the battery and it begins to work. Many patients forget to remove this sticker and assume the battery is faulty or that their hearing aid has malfunctioned. If you're experiencing issues are changing a battery, always check to make sure the activation sticker has been removed from the battery.

Leave battery compartments open overnight

Depending on battery size and your usage, you can expect your batteries to last anywhere from three to 20 days. However, turning your hearing aids off when they're not in use and leaving the battery compartment open overnight can help you to maximize the lifespan of your hearing aid batteries. In addition to this, leaving the battery compartment open overnight will ensure any moisture evaporates and reduces the risk of damage occurring.

Store them carefully

As hearing aid batteries are so small, they can easily be picked up by young children and pets. If swallowed, zinc-air batteries can be extremely harmful, so it's vital you seek urgent medical assistance if you suspect anyone or any animal has swallowed a hearing aid battery. To try and reduce the risk of hearing aid batteries falling into the wrong hands, identify a secure storage location which children and pets are unable to access.


Put up with a reduced battery life

Although the life of a hearing aid battery depends on your usage, size 10 batteries usually last between three to seven days, while size 312 can last from three to 10 days. For patients who use size 13 or size 675 batteries, you can expect them to last from six to 14 days or nine to 20 days, respectively. If your hearing aid batteries aren't lasting as long as they should, it may be a sign that your hearing aid isn't working properly. Visit your audiologist so that your device can be tested and any faults rectified.

Store them in humid areas

Batteries should be stored at room temperature, and keeping them in a humid environment can affect their performance. Kitchens and bathrooms can be particularly humid and have a relatively high moisture content, so avoid keeping them in these rooms if you can. Similarly, don't store hearing aid batteries in an environment which is too cold. Some people believe that putting hearing aid batteries in the refrigerator will make them last longer, but there's no evidence that this is true and the refrigerator may actually cause them to deplete faster because of condensation causing the tab to become loose.

Put them in the garbage

When your hearing aid batteries have run out, don't simply discard them or put them in the trash. Batteries need to be disposed of carefully, and in accordance with specific regulations, so you'll need to find out what your state guidelines are. Many audiologists provide a drop-off facility which enables you to dispose of hearing aid batteries safely, so it's best to make use of these services when you can.
