New battery insertion instructions

Remove the tab from the battery. Next, let the battery sit for 3-5 minutes before putting it into the hearing aid. Your hearing aid takes zinc air batteries, which need air in order to charge to their maximum potential. By letting the batteries sit before placing them in your hearing aid, you will gain one to two days of extra battery life.

  • Note: You only have to let your battery sit the first time you use it, after you initially remove the tab.


  • Keep your battery door open at night to turn off your hearing aid and get maximum life out of your batteries!
  • Throw away your old set of batteries before removing the tab from new set to avoid mixing up the old and new batteries.
  • To remember the last day you changed your batteries, stick the battery tab on your calendar every time you change batteries.
  • A warning signal will be played when the battery is low in each hearing aid.
    • Most hearing aids give a two to ten hour notice of low battery.

Important Reminder

Batteries are toxic and not to be swallowed; please dispose carefully. Keep batteries away from small children and animals. If you have ingested a battery, immediately call the national battery hotline at (202)-625-3333.
