EFY: Batteries provide power to many different applications across a wide range of industries. In many of these applications, a charging connector is difficult or impossible to use. For example, some products require sealed enclosures to protect sensitive electronics from harsh environments and to allow for convenient cleaning or sterilization. Other products may simply be too small to include a connector, and it is better to forget about charging with wires in products where the battery-powered application includes movement or rotation. Wireless charging adds value, reliability and robustness in these and other applications.
