Tips and Techniques

Follow these tips for optimum battery usage and to protect your hearing instrument from battery-related damage.

  • Excessive heat or cold shortens the life of your batteries. Always store your batteries in a cool and dry place. Do not store your batteries in a refrigerator or freezer.
  • Moisture shortens the life of your batteries. Do not store batteries in the bathroom.
  • Batteries should not be carried in pockets/purse—they may touch metal objects and be prematurely discharged.
  • If the hearing aid is not worn overnight, ensure that it is turned off and the battery holder is fully opened to conserve battery power and reduce any potential damage from moisture.
  • If you do not intend to use the hearing aid for a few days, ensure the battery is removed.
  • Before inserting the battery into the hearing aid, please ensure the battery is dry and at room temperature.
