Rechargeable hearing aid solutions have been available for several decades, but only recently have they been streamlined and designed for ease of use. Rechargeable hearing aids provide two main benefits: they save money and they save the environment.
Most traditional hearing aids use zinc air batteries that operate in the 1 to 1.6 voltage range. With older hearing aid models, ones that did not boast the wireless and digital capabilities now available, batteries did not require frequent replacement. With newer hearing aid models and more advanced technology, traditional zinc air batteries don’t last as long as they once did. You may find yourself changing out your batteries a few times a week now, rather than once a month.
At this rate, for two hearing aids, the cost of hearing aid batteries adds up over a year. On a larger scale, the number of zinc air batteries that make their way to landfills annually adds up in a huge way. It is estimated that 150 billion zinc air batteries are dumped in landfills annually. This amount of waste is dangerous to the environment, as batteries can leak into water supplies and cause hazards to health.
Rechargeable hearing aids and rechargeable battery solutions are the way forward, for sustainable energy!
