The life of your hearing
instruments' batteries will vary
depending on length of daily
use, listening environments, and how your
hearing instruments are programmed. When
the hearing instrument batteries go dead,
remove them immediately and replace them
with new batteries. Batteries may be purchased
through your hearing healthcare professional.
When your hearing instruments are not in use,
open the battery compartment to prevent
excessive battery drain and ventilate the
instruments.
Important: Always discard used batteries. Small
batteries can be harmful if swallowed. Keep
batteries out of the reach of pets and small
children. In case of ingestion, contact your
physician or call the National Button Battery
Hotline collect at (202) 625-3333.
