5PK Maxell Silver Oxide SR726SW Low Drain Watch Battery Replaces 397, 10L102, D397, D396, BS26, SP397, SG2, 8033, W2U The 397, or SR726SW, 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). 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. 5PK Maxell Silver Oxide SR726SW Low Drain Watch Battery Specifications Chemistry: Silver Oxide, Nominal Voltage: 1.55V, Nominal Capacity: 33mAh, Nominal Discharge Current: 50 (?A), Diameter: 7.9 mm, Height: 2.6 mm, Weight: 0.5(g), 5PK Maxell Silver Oxide SR726SW Low Drain Watch Battery Features 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 5PK Maxell's original leak-resistant processing, the SR battery has excellent leakage resistance
