Most hearing aids are powered by disposable batteries. The size and style of your hearing aids will determine the correct battery size and how long they will last. Here are some easy tips to ensure your hearing aid batteries last as long as possible.
- The first obvious thing is to remember to turn off your hearing aid when you are not using it. Do this by opening up the battery door. If you have a custom (or “in ear”) hearing aid, make sure to open the battery door the whole way. Custom hearing aids can be very small so the battery might still be connected if you only open the battery door slightly.
- It’s also important to know that hearing aids use zinc-air batteries. This means that once you take off the sticker from the battery, it draws in air and starts to run down. So keep the batteries in the packet until you are ready to use them. Did you know that before you put the battery in you should let it rest for a minute? It gives the battery more time to draw air in to charge up and helps it to last longer.
- Hearing aid dryers or dehumidifiers will shorten the life of the hearing aid batteries. If you use one of these, make sure to remove the batteries from the aids and store them completely outside of the dry aid kit.
