5PK Maxell Silver Oxide SR716SW Low Drain Watch Battery Replace 315 SR67 V314 The 315, or SR716SW, 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. 5PK Maxell Silver Oxide SR716SW Low Drain Watch Battery Specifications Chemistry: Silver Oxide, Nominal Voltage: 1.55 (V), Nominal Capacity: 22mAh(mAh), Nominal Discharge Current: 30 (?A), Diameter: 7.9(mm), Height: 1.68(mm), Weight: 0.3(g), 5PK Maxell Silver Oxide SR716SW 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 resistance315 / 314. Length: 0.0600, Width: 0.3100, Height: 0.0600, Diameter: 0.31. Voltage: 1.55, Amperage: 22mAh, Chemistry: silver_oxide.
