When you purchase a hearing aid, you will be instructed about inserting and removing the device, turning it on and off and cleaning it. You will also learn how to insert and remove the small batteries that power your hearing aid.
Hearing aid batteries are being replaced in some cases with rechargeable hearing aids, but the smallest devices that so many people like because they are nearly invisible still require standard batteries. Generally, the smaller the device, the smaller the battery.
These batteries are zinc-air activated. When you peel the backing, wait about a minute and place the battery in your hearing aid tray. Today’s hearing devices have an alert that the battery is working and an alert when it is running low. When you start your device, it should tell you the state of the battery.
Audiology & Hearing Center of Tampa has all the battery types in stock and can help you learn to change them in any device. Here are the four types of batteries and their uses:
- 675 – color blue, largest regular battery for most powerful hearing aids
- 13 – color orange, medium-size battery
- 312 – color brown, medium-size battery
- 10 – color yellow, smallest regular battery.
Battery life and use
Battery life depends on the condition of the hearing aid, the age of the battery, the volume and connected use of the device and how long the hearing aid is worn each day. Always disconnect the battery at the end of the day by opening the battery tray, stopping the connection with the internal metal port.
There are several recommendations that will make batteries last longer:
Store them in cool, dry rooms. Never remove their sticky color tabs until ready to use.
Always open the battery door when putting your hearing aids away for the night. This disconnects the battery from the hearing aid connector.
Make sure you are buying fresh batteries when you purchase. Check the packages as soon as you receive them.
