Hearing Aid Batteries

All batteries are toxic and dangerous if swallowed. Keep all batteries (and hearing aids) away from children and pets. If anyone swallows a battery it is a medical emergency and the individual needs to see a physician immediately.  One question often asked is "How long does the battery last?" Typically, batteries last 5-15 days. However, as power consumption increases and as battery size decreases, battery life decreases.

Today's hearing aid batteries are "zinc-air" meaning "air-activated." Once the factory-sealed sticker is removed from the back of the battery, oxygen in the air contacts the zinc within the battery and the battery is "turned-on". Since several Oticon hearing instruments use the battery door as an "off" switches, removing the battery from the hearing aid circuit or opening the battery door when not in use, assures the device is turned off.
