Everything You Need To Know About Hearing Aid Battery Safety

Hearing aid batteries do a lot of good, which is why most of us don’t think about the dangers that can be associated with them in potential worst-case situations. Hearing aid batteries pose a decent amount of safety concerns that users should be aware of. They are more than just a choking hazard — the poisonous toxicity of a hearing aid battery can sometimes result in death.

If you or someone you know is a hearing aid user, we’ll go over everything you need to know about hearing aid battery safety to ensure you keep yourself and those around you safe in this blog post. Swallowing a battery may seem like a rare case, but recent data shows Canadians purchase about 550 million disposable batteries annually — accidents are bound to happen with a number that large.

Unfortunately, hearing aid batteries can be very dangerous if they are swallowed. This is most common among pets and children, but the effects are just as dangerous if an adult were to swallow these batteries.

Here are some common symptoms of hearing aid battery ingestion:

  • Vomiting/Nausea
  • Blood swelling in the back of the throat.
  • Drooling/Excessive drooling
  • Painful swallowing or difficulty swallowing
  • Pain in the chest or throat

If you or someone else has swallowed a hearing aid battery, please contact your local emergency department immediately. Have the battery identification number, which can be found on the packaging or a separate similar battery, handy, if possible. Do not let this person eat or drink anything, and avoid inducing vomiting.


There are multiple physical risks that can occur when a human or pet swallows a hearing aid battery. The alkaline material in the battery can leak, ultimately resulting in internal burned body tissues from the chemicals.

They are also potential choking hazards, and signs of internal burns from batteries can occur as early as 2 hours after ingestion. In the worst possible case scenario, the battery can burn through major internal vessels, which can result in death.


In the case of hearing aid battery safety, prevention is more important than cure. There are several ways you can keep hearing aid batteries out of the hands of those who aren’t responsible or competent enough to understand their dangers. Here are a few prevention tips:

  • Keep your batteries stored in a safe place, out of reach of children and pets.
  • Don’t let your children play with your hearing aid or hearing aid batteries.
  • When you change your hearing aid battery, do so over a flat surface — counter, table, etc. Also, flatten a cloth over the flat surface. This way if you accidentally drop one, it can be easily found, and the cloth will ensure the battery doesn’t bounce off the surface.
  • Don’t put your batteries near any food or drinks. This will keep them from being confused for a pill or piece of candy.
  • NEVER put a hearing aid battery in your mouth, and discourage others around you from doing so as well
  • Keep your batteries in an isolated, well-labeled bag so they don’t get mistaken for pills or some other type of small edible object.
