Maxell is the first company in Japan to successfully market button-type silver oxide batteries and has many years of experience and know-how.
Also, in consideration of the environment, all products are designed to use zero mercury. Button-type silver oxide batteries are characterized by high energy per unit volume and stable operating voltage. As a result, they are used as a power source for applications such as quartz watches, and in recent years their use has expanded to medical devices and BLE devices.
