Make sure you are sitting down with your battery pack and a pair of scissors, ideally over a table. Carefully use the scissors to cut and open the pack and access the hearing aid batteries one by one. Think of this as like cutting a slice of a pie. Remove the RAYOVAC hearing aid battery from the package. Remove the tab and let sit for one minute to allow air to activate the battery Then insert the battery into your device with the flat side facing up and close the door Your hearing aid should now be powering up and is ready for use
