How often do I need to change the batteries in my hearing aids?

Batteries should be changed about every ten to 14 days. The exact schedule for changing batteries depends on the amount of time the hearing aids are worn and the power consumed over time. Most new digital hearing aids have battery warning indicators. Before the battery goes out, the hearing aid will " beep, beep, beep " to tell you you have another hour or two before the battery fails. Using excellent, fresh batteries is important, and changing batteries should take no more than 60 seconds.

Please discuss 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 they last 7-14 days based on 16 hours per day use cycle. Batteries are inexpensive, costing less than a dollar each. Generally, the smaller the battery size, the shorter the battery life. The sizes of hearing aid batteries are listed below along with their standard number and color codes.

Size 5: RED
Size 10 (or 230): YELLOW
Size 13: ORANGE
Size 312: BROWN
Size 675: BLUE

Today's hearing aid batteries are " zinc-air. " Because the batteries are air-activated, a factory-sealed sticker keeps them " inactive " until you remove the sticker. Once the 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 many of today's automatic hearing aids do not have " off " switches, removing the battery from the hearing aid circuit, by opening the battery door, when not in use, assures the device is turned off. Zinc-air batteries have a " shelf life " of up to three years when stored in a cool, dry environment. Storing zinc-air hearing aids in the refrigerator has no beneficial effect on their shelf life. In fact -- quite the opposite may happen. The cold air may actually form little water particles under the sticker. Water is made of oxygen and hydrogen. If the water vapor creeps under the sticker, oxygen may contact the zinc and the battery could be totally discharged by the time you peel off the sticker! Therefore, the best place to store batteries is in a cool dry place, like the back of your sock drawer, not the fridge!

What are Assistive Listening Devices (ALDs)?

You may have certain communication needs that cannot be solved by just using hearing aids. These situations may involve telephone, radio, television, or the inability to hear the door chime, telephone bell, and alarm clock. Special devices have been developed to solve these problems. Like hearing aids, assistive listening devices and alerting devices make sounds louder. Typically, a hearing aid makes all sounds in the environment louder. Assistive listening devices and alerting devices can increase the loudness of a desired sound, like a radio or television, a public speaker, or an alarm system, or may make an auditory alarm (such as a smoke signal) into a visual alarm (such as a strobe light). .
