How to Use:

1. Remove the protective sticker from the battery and wait approximately 2 minutes before inserting it into your hearing aid. This allows air to enter the battery and activate the zinc-air technology.
2. Insert the battery into the hearing aid according to the device manufacturer's instructions. Keep the battery compartment open overnight where recommended to allow air circulation and help reduce moisture build-up. Switch off your hearing aid when not in use for extended periods.
3. Store unused batteries in their original packaging in a cool, dry place at room temperature. Do not store batteries in the refrigerator or expose them to extreme temperatures.
4. Do not mix new and used batteries or batteries from different brands. Keep batteries away from metal objects and out of reach of children. Always follow the hearing aid manufacturer's instructions.
