Maxell 364 SR621SW 1.55V Silver Oxide Watch Battery (Pack of 5)

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. Features: - Stable discharge characteristics - High-energy density - Volume 100% leakage resistance prevents damage to your watch or other specialty electronic - Zero mercury - 1.55V Excellent discharge load characteristics
Alkaline electrolyte is used to provide excellent discharge load characteristics. Depending on the composition of the electrolyte, two models are available; a low-drain type (SW type) for analog watches and a high-drain type (W type) for multi-function watches (which incorporate an alarm and light), medical equipment, etc.
