for your information
The best way to ensure better hearing is to practice listening until you can wear your hearing instruments comfortably all day. In most cases, infrequent use of your hearing instruments will not give you the full benefits.
Your hearing instruments will not restore normal hearing, nor will they prevent or improve a hearing impairment resulting from a physiological condition. What they will give you, however, is help towards making better use of the hearing ability that you have. If you have two hearing instruments, it is important to always wear both.

Tips to Help Extend Hearing Aid Battery Life:
Q. How do I dispose of my hearing aid batteries?
A. Zinc air batteries should be disposed of in your normal trash and not accumulated. Accumulating batteries can lead to a risk of fire.
Q. Should I open the battery door on my hearing aid when it is not in use?
A. Yes - it is a good idea to open the battery door on your hearing aid when your hearing aid is not in use. This stops excessive drain on the battery and may allow air in to remove any moisture build up.
Q. How should I store my batteries for best hearing aid battery life?
A. To get maximum hearing aid battery life, keep batteries at room temperature. Heat can shorten battery life and a damp location like the fridge is not recommended. Also, never carry loose batteries in your pocket or purse. Contact with metal items like keys or coins can short circuit the battery. Never store your batteries with your medication, as you might accidentally ingest one. Always store batteries out of reach of children and pets. If a battery is swallowed, seek medical attention.
Q. The battery does not seem to work right away - is something wrong?
A. Zinc air batteries take about a minute to power up. That's because it takes time for the outside air to penetrate the battery's tiny air holes and mix with the battery's zinc chemistry to power your hearing aid.
Q. Why does my hearing aid battery have a tab on it?
A. Zinc air hearing aid batteries use outside air as a source of power. The tab seals the zinc in the battery from exposure to air ensuring freshness when purchased. After you remove the tab, the battery takes about a minute to fully charge and to be ready for use. Do not remove the tab until you are ready to use the battery. Once the tab is pulled and the zinc is exposed to air, replacing the tab will not extend the battery life.
Q. How do I get the best performance from my hearing aid batteries?
A. To get the best performance, keep moisture from clogging the air hole by opening the battery door at night or any time you are not wearing you hearing aid.
Q. How long is the expected life of my hearing aid battery?
A. Hearing aid battery life is determined by the length of use during the day, amplification and type of hearing aid. Consult your hearing care professional to determine the length of hearing aid battery life.
Q. Why does my hearing aid use so many more batteries than my watch?
A. It is not possible for a hearing aid battery to last as long as a watch battery because hearing aid circuits are much more sophisticated and draw much more power than a watch. Hearing aids and their electronic components use a tremendous amount of power - about 50 to 100 times the power used by a watch. The new technology hearing aids even run a computer program on the power provided by a tiny battery. While it is possible to design a battery that would last two to three months, most people are unwilling to give up the small size of today's hearing aids in exchange for that longer life.
Q. How to Maximize Battery Life
A. First it is helpful for you to understand a little about how hearing aid batteries work. They are called zinc air batteries because they are activated by air. Underneath the tab are tiny holes. When you pull the tab off, air enters the battery and interacts with the ingredients, producing electricity.
Your environment and battery handling can affect battery life. Battery performance will be impeded if anything gets into those holes and clogs them. Dirt, or even skin oils, can clog these minuscule holes, so it is best to minimize battery handling before inserting it into the hearing aid.
Loud and busy environments can shorten battery life. For example, a person in a Las Vegas casino may notice their battery doesn't last as long as it does at home. That is because processing the casino's many loud sounds all at once requires a lot of battery "juice." This same principle applies to a concert or even a lively family get-together.
