New batteries for hearing aids,
all of them have a sticker on the back,
what is that sticker for?
Why do you have to peel it off before use?
The zinc-air battery used in hearing aids, when needed to be used, peel off the small sticker, place the battery for a few minutes to allow the zinc in the battery to fully contact with air and produce a chemical reaction to generate electricity. Once the battery is activated, there will be a certain amount of power loss even if it is not used, and that layer of sticker is to prevent the battery from contacting with air.
Precautions for use
- If not using immediately, don’t peel off the sticker
Because once the sticker is peeled off, it will activate the electrochemical reaction inside the battery, and even if it is reattached, the chemical reaction will continue until the power is exhausted.
- Do not stockpile in large quantities
Although the storage period of hearing aid batteries is 2 to 4 years, they will slowly consume power during storage. It is recommended not to exceed half a year’s worth, just enough to use.
- Store in a cool, dry place
Hearing aid batteries should be placed in a cool, dry place to prevent the battery from getting damp and affecting the service life.
- Disconnect the hearing aid from the phone when not using Bluetooth
The more functions the hearing aid has, the greater the power consumption. For example, when not watching TV or making calls, you can temporarily disconnect the Bluetooth connection from the TV or phone.
- Purchase branded batteries
Hearing aids are precision electronic devices with strict requirements on battery voltage and power. High-quality batteries have more stable voltage and more power. Therefore, it is recommended to choose products from reputable manufacturers.
