How to use

Remove one battery from the package and peel off the protective adhesive tab to activate the zinc-air cell. Wait a few seconds after removing the tab to allow the battery to reach optimal output before inserting it into the hearing aid compartment. Ensure the battery is placed with the correct polarity as indicated in the device; close the battery compartment securely. Replace batteries as performance decreases or according to the device manufacturer’s guidance, and dispose of spent cells in accordance with local regulations for battery waste.

Usage recommendations

Store batteries at room temperature in a dry place and keep them in their original packaging until use to preserve shelf life. For best performance, remove the protective tab shortly before use and allow a brief activation period. Replace all batteries at the same time if your hearing aid uses multiple cells, and carry spare cells when away from home to ensure uninterrupted device operation.
