After removing the tab from the battery, let the battery sit for 3-5 minutes before installing it in your hearing aid. This “activation” time allows air to reach the materials inside the battery and activate them.
When you’re not wearing your hearing aid, turn it off or open the battery door to minimize battery drain.
If you won’t be using the hearing aid for an extended period of time, remove the battery entirely.
Avoid storing in extreme temperatures to keep from draining battery power and shortening battery life.
