The device for amplification and correction of hearing needs a battery, which is a battery. At the same time, all batteries for hearing aids differ in their purpose, capacity and size. Therefore, it is important to choose the right model, starting from the power of the device.
Types of batteries for hearing aids
For the convenience of users, who are often elderly people, all existing types of batteries for hearing instruments are color coded.
So, here are the main types of batteries for devices:
- battery with size 312 - has a brown coding and is intended for in-ear and micro-behind-the-ear hearing aids;
- batteries for hearing aids with the marking 675 - with blue coding, are designed for super-powerful and powerful BTE devices;
- a battery for a hearing aid with size 13 - has an orange coding and is used in practically all programmable and digital devices for hearing of the BTE and in-ear types;
- battery with size 10 - with yellow coding, is used for in-channel hearing aids.
It is very important to purchase batteries of the right type and size. Find them most easily in the same place where the hearing aid was purchased. As an option - you can buy batteries from the audiologist. This will ensure that the marking and size match.
Surely you are aware that all batteries for hearing aids are air-zinc. They are the safest for the environment. The fact is that such batteries are activated only after the protective film has been peeled off the smooth side of the battery marked with a "+" sign.
Timely change of battery in the hearing aid
It is better not to rely on your memory, and make notes on the calendar, highlighting the date when you put a new battery in the device. Measuring once the time, which is enough for its charge, you can next be ready to change the battery.
This is important, especially in cases where you have to attend an important meeting or negotiations. Knowing about the day when the battery sits, you will change it in advance for a new one and calmly go to an important event.
Do not store used batteries in order not to confuse them with new ones. And always carry a spare battery. Modern digital hearing instruments deliver signals, warning you of an early failure of the battery, so you will have a few minutes to change it.
In addition, the audiologist can buy a battery tester, which will help determine the cause of problems with the hearing aid, eliminating the problems with the battery.
How do I change the battery in my hearing aid?
After removing the protective film from the new battery, wait a couple of minutes for it to activate and carefully install it, observing the polarity. At the same time, make sure that the "+" is visible on the installed battery. If you insert it incorrectly, the machine will not work, in addition, you can damage the battery compartment cover when trying to close it.
In general, when closing the lid, do not exert any effort, as the hearing aid itself can be damaged. Also, monitor the condition of the contacts - there should be no traces of oxidation, earwax, mold, fungus or acid. If you notice any of the above, contact a specialist.
How to store the battery reserve?
Keep the batteries in a cool and dry place, and in no case in the refrigerator, as this will significantly shorten their life.
During periods when you are not using the unit, open the battery compartment and take out the batteries so they do not oxidize. Do not put batteries into the hearing aid for watches and other appliances. This will damage the unit.
