Hearing aids are small electronic devices designed to amplify sound, making it easier for individuals with hearing loss to communicate and participate more fully in daily activities. Over-the-counter (OTC) hearing aids have emerged to make hearing aids more accessible and affordable. OTC hearing aids can be bought directly without a prescription and are designed for people with mild to moderate hearing loss. This development has been driven by the desire to increase accessibility to hearing aids, reduce costs, and address the growing demand for hearing solutions as the population ages.
(OTC) hearing aids come in various types, including behind-the-ear (BTE), in-the-ear (ITE), and completely-in-canal (CIC) models, each catering to different levels of hearing loss and user preferences. Different types of over-the-counter (OTC) hearing aids may have varying requirements for battery shape and size. Traditional hearing aids often rely on disposable zinc-air batteries, which need frequent replacement. However, the growing demand for convenience and sustainability has led to an emphasis on rechargeable batteries in OTC hearing aids. These rechargeable batteries, typically lithium-ion or lipo batteries.
●Convenience and Ease of Use: No need to frequently replace disposable batteries. Easier for those with dexterity issues. Simple charging process, often with a docking station.
●Cost-Effective: Saves money over time by eliminating the need to buy disposable batteries.
●Consistent Performance: Provides a stable power supply, reducing the risk of sudden battery failure.
●Environmentally Friendly: Reduces battery waste and environmental impact.
●Rechargeable Lithium-Ion Coin Cell (Custom options: diameter ≥7.8mm; height ≥1.5mm)
