Zinc air batteries have long been the trusted power supply for hearing aids, but as hearing aids become more advanced, with wireless capabilities and sophisticated processing platforms, batteries must be replaced more often. In the past, traditional zinc air hearing aid batteries were changed once or twice a month, but with newer technology, some require a change every few days.
In the span of a few years, this can add up. Some hearing aid wearers find they are spending up to $150 a year on hearing aid batteries alone. Meanwhile, there is less confidence in the lasting power of batteries. Instead of feeling confident that your hearing aids will work for you anywhere you go, you must remember to bring an extra set of batteries with you, just in case. If you lead an active lifestyle, or find yourself often in louder settings, your hearing aids will process more auditory information, which will require more battery power.
Annually, 150 billion zinc air batteries make their way to landfills. As they are not recyclable, these batteries become waste product which run the risk of seeping lead and acid into underground water supplies and become an environmental hazard.
Traditional zinc air batteries are a drain on your pocketbook and are harmful to the environment. If there’s another solution, would you take it?
Phonak has recently introduced a new rechargeable hearing aid solution, using lithium-ion battery technology (the same kind of long-lasting rechargeable battery that powers your laptops, cell phones, and tablets). With rechargeable battery technology in hearing aids, the concerns with traditional hearing aid batteries are thing of the past.
