Lithium-ion (li-ion) batteries are everywhere! From life-saving medical equipment to futuristic looking electrical cars, from smartphones to hearing aids, li-ion batteries keep the essentials and the comforts of modern life running safely and reliably. In the premium segment, Sivantos even now sells ¾ of hearing aids with li-ion technology.

The advantages of rechargeable hearing aids are clear: they save money in the long run and are easy to handle. No more tiny battery doors to open to exchange batteries regularly. With an inductive charger, recharging hearing aids overnight is more convenient and safe than the use of common zinc-air batteries as it allows for easy recharging of devices with wireless magnetic fields. The hearing aids start charging automatically as soon as they are placed in the charger.

Did you know that unlike older types of batteries, li-ion batteries no longer have a memory effect? This means that the well-known cycle of “always fully charged” to “always fully discharged” is outdated. Rather, the opposite is the case: The batteries work best when their charge level is between 20 and 80 percent. Modern batteries, like the ones we use in our hearing aids, help the user by blocking an area at the top and bottom of their capacity automatically. The result: your hearing aids will be charged just perfectly overnight.
