Rechargeable hearing aids are becoming a popular choice for users who want to avoid the hassle of disposable batteries, according to information released on Mar. 16.
The topic is important as more people seek convenient and environmentally friendly solutions for hearing loss, but must weigh these benefits against potential drawbacks.
Rechargeable hearing aids use built-in batteries that can be recharged overnight using a docking unit, similar to charging a smartphone. These batteries typically last about five years before needing replacement, while disposable batteries require changing every few days or weeks depending on the device. Rechargeable models are most common in behind-the-ear styles, though in-ear options are increasing.
Advantages of rechargeable hearing aids include convenience, safety for children and pets, environmental benefits, and easier handling for those with dexterity issues. Tim Cross, a hearing instrument specialist and owner of Earzlink Hearing Care in Hillsboro, Ohio, said: “If peeling the tab off a battery and not dropping it, or being able to get it to fit into the compartment, is difficult for somebody, then rechargeable would be a huge advantage.”
Cross shared an example from his practice: “Quite frankly, you could drive down the street and hear her television or pound on the door and she would not hear you,” he said about a 90-year-old patient who struggled with traditional batteries due to limited dexterity and sight. After switching her to rechargeable devices and keeping an extra charger at his office for emergencies, Cross said: “It totally changed her life,” adding that it also gave her family peace of mind.
However, there are disadvantages. Some users may find themselves without their devices if the battery needs replacing since many rechargeable models do not allow user removal of batteries. "For the most part, it’s very simple and basic," Cross said. "But some people might not think beyond the normal routine and process (such as power outages or if the grandkids accidentally unplug the charging unit). In these situations, it’s much easier to just pop in a new set of batteries." Other concerns include dependency on daily charging units—though some manufacturers now offer portable smart chargers—and additional upfront costs for chargers and replacement batteries.
Historically, fewer style options have been available for those preferring discreet in-the-ear models; however, new products like Oticon Zeal offer both rechargeability and in-ear wear.
Experts recommend discussing individual needs with a local hearing care provider before choosing between rechargeable or disposable battery-powered devices.
