5PK Maxell Silver Oxide Watch Battery SR721W High Drain Replaces 361 SR58

The 361, or SR721W, is a rare Silver-Oxide cell normally used in watches, with a shelf life of 5+ years. Other applications may include calculators, film cameras, medical instruments, cash registers, or FA instruments (Measuring Instruments, Onboard Microcomputers, Sensors).High Drain batteries are for applications with a continuous, low power consumption and occasional high peaks: Analog and digital watches with extra functions (backlight, alarm), pocket calculators, electronic games, cameras, etc. This is in comparison to low drain batteries, which are best used in devices that use a small amount of power over a long time: Analog watches, TV remotes, alarm clocks, etc.

• Chemistry: Silver Oxide
• Nominal Voltage: 1.55V
• Nominal Capacity: 25(mAh)
• Nominal Discharge Current: 50 (µA)
• Diameter: 7.9 mm
• Height: 2.1 mm

• Flat discharge characteristics A flat discharge curve during discharge supplies a stable voltage until the end of the discharge life.
• High-energy density High-energy density per unit volume provides approx. twice as the amount of energy capacity as button-type alkaline batteries.
• Excellent discharge load characteristics Employing an alkaline electrolyte, the SR battery features excellent discharge load characteristics. Depending on the composition of the electrolytes, two models are available;
• a low-drain type for analog watches, and a high-drain type for multi-function watches incorporating an alarm, illumination light, etc.
• Superior leakage* resistance Featuring Maxell's original leak-resistant processing, the SR battery has excellent leakage resistance, which suppresses the electrolyte from rising up and seeping out — a basic phenomenon of alkaline electrolytes.
