5PK Maxell Silver Oxide Watch Battery SR731SW Low Drain Replaces 329

This battery is a 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). This is a "SW" low drain battery. Low drain batteries are best used in devices that use a small amount of power over a long period of time: Analog watches, TV remotes, alarm clocks, etc. This is in comparison to high drain batteries, which are for devices with a continuous, low power use and occasional high peaks: Analog and digital watches with extra functions (backlight, alarm), pocket calculators, electronic games, cameras, etc.

• Chemistry: Silver Oxide
• Voltage: 1.55V
• Nominal Capacity: 12.5(mAh)
• Nominal Discharge Current: 20 (µA)
• Diameter: 7.9 mm
• Height: 3.1 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.
