SR621SW Silver Oxide Watch Battery 1.55V, 23 mAh : SR621SW VS SR626SW, Datasheet and Equivalents

The SR621SW  is a Silver-Oxide cell that is commonly used in timepieces and has a 5-year shelf life. Calculators, film cameras, medical instruments, cash registers, and FA  instruments are examples of other applications (measuring instruments, onboard microcomputers, sensors). This is a low-drain "SW" battery. Low-drain batteries are ideal for devices that require a tiny amount of power over a long period of time, such as analog timepieces, TV remote controls, and alarm clocks. This is in contrast to high-drain batteries, which are used in devices with constant low power consumption and occasional high peaks, such as analog and digital watches with additional functions (backlight, alarm), pocket calculators, electronic games, cameras, and so on. Specifications Chemistry: Oxide of silver 1.55V voltage 6.8 mm in diameter Dimensions: 2.2 mm Dimensions: 2.2 mm Dimensions: 2.2 mm Low-Drainage Style.
