1. How long will my batteries last?
They will last for up to 3 years if you keep them in the package and don’t use them. But, we know that's not what you're trying to do. Hearing aid batteries typically last about 5 to 7 days, depending on usage. If you use a lot of Bluetooth streaming from your phone to your hearing devices, you may have to replace your batteries sooner. Users that make a lot of phone calls or listen to music through their hearing aids may need to replace their batteries every 2 to 3 days.
2. Are your batteries any good?
Our hearing aid batteries are mercury-free Power One brand zinc air batteries. They’re manufactured in the world’s largest and most up-to-date hearing aid battery plant in Ellwangen, Germany. We provide eco-friendly battery technology, produced under clean room conditions, with an Enhanced Safety & Performance housing coating.
3. What if my batteries don't seem to work?
We have never heard of a case where our batteries arrived drained. To activate the battery, remove the protective tab from its back and let it sit for a few minutes before putting it into your hearing aid. Removing the tab from the back lets the metal surface come in contact with air, which starts the chemical reaction to release the stored energy and power your hearing aids.

8. How should hearing aid batteries be stored?
Ideally, you don’t need to store your hearing aid batteries at all. We will take care of that for you and send you fresh hearing aid batteries each month. Any unused batteries should be stored in a dry and cool location.
In any case, please don’t store your hearing aid batteries in the refrigerator. Zinc air batteries have holes in the top and if you store them in the refrigerator, the holes will allow moisture to get into the battery. This moisture can cause a premature failure of the battery. If you want to preserve the life of your hearing aid batteries, keep them out of the refrigerator.
9. How do I dispose of a used hearing aid battery? Are they recyclable?
Our zinc air hearing aid batteries are classified as non-hazardous waste and can be easily disposed. However, with an eye on our environment, we would love to receive the batteries back from you to recycle them. Simply put them in an envelope, put a stamp on it, and send them to OTOjOY, 221 E Indianola Ave, Phoenix, AZ 85012. If you don’t want to send them back, we recommend bringing the batteries to a common local collecting point to make sure they can be recycled.
10. How are mercury-free batteries different from standard batteries? How do they compare in performance?
The lifetime for mercury-free zinc air and standard batteries is identical. Mercury-free cells, however, are classified non-hazardous, because there is no mercury added, making these batteries more environmentally friendly. With its high energy density and almost flat drain curve, zinc air batteries also provide perfect characteristics for hearing aids. They are the ideal power supply for hearing aids, including those with digital functionality.
11. What should I do if a hearing aid battery is swallowed?
Hearing aid batteries must be stored out of the reach of small children and pets to prevent them from swallowing a battery. If batteries are ingested, call the 24-hour Button Battery Ingestion Hotline at (202) 625-3333, provide them with the battery type, and seek medical help immediately.
