How to use

Before installation, remove the protective tab or strip to allow the cell to contact air and begin producing voltage. Insert the cell into the battery compartment of the device following the polarity indicators and any device-specific instructions. Allow a short activation time if recommended by the device manufacturer, then verify device operation. Replace all batteries in multi-cell devices at the same time if advised by your device manual to ensure balanced operation.

Usage recommendations

Store unused cells in their original packaging at room temperature away from direct sunlight and moisture. Dispose of used zinc-air batteries according to local regulations for battery waste; do not incinerate. If you experience unexpected performance, consult the device manual or a certified hearing care professional for guidance on correct battery type and installation.
