The design of a hearing-aid system involves three disciplines of applied science–electrochemistry, electrical engineering and audio engineering. This paper is concerned with the interface between the first two. Batteries are essentially non-linear components. Optimum performance is only achievable when the electrical requirements of the hearing aid are closely matched with the voltage, rate capability and impedance of the battery. After years of optimalization, the modern ‘675’ button cell has earned universal acceptability and is now used in most ‘behind-the-ear’ hearing aids. When more power is required, the larger and less specialized LR6 ‘penlight’ cell is typically specified. Higher voltage might lead to better circuit efficiency, and there is some pressure to introduce a 3 V lithium-based product. Lithium should give superior energy density, but there are problems which remain to be solved. In the end, it is quite possible that the market might settle for an ecologically acceptable long-life lower voltage metal-air cell. If so, the recent zinc-air system may well have a future and could conceivably succeed both the mercury ‘675’ and the alkaline ‘penlight’ cells.

JH-W3 TWS BTE rechargeable bluetooth hearing aids combine the benefits of rechargeable batteries with the convenience of bluetooth connectivity. These hearing aids can be easily charged using a 3-in-1 portable charging case. These rechargeable bluetooth hearing aids can wirelessly connect to compatible devices such as smartphones, tablets, and computers. This connectivity enables users to stream phone calls, music, podcasts, and other audio directly to their bluetooth rechargeable hearing aids without needing additional accessories.
Non-prescription hearing aids are designed to address mild to moderate hearing loss, and to provide an accessible and affordable option for individuals seeking amplification. JH-A17BT OTC hearing aids are designed to be extremely discreet and difficult to detect when worn. These hearing aids without prescription are engineered to blend seamlessly with the wearer’s natural appearance, making them virtually invisible to others.
JINGHAO Rechargeable in-the-ear (ITE) hearing aids are compact devices that fit inside the ear and are designed to provide an improved hearing for individuals with hearing loss. Unlike traditional hearing aids that use disposable batteries, rechargeable in the ear hearing aids come with built-in rechargeable batteries.
