Maxell Silver Oxide SR1120SW Low Drain Watch Battery Replaces 381, LR1120, SR55, 1160SO, 391, 191-1, 280-27, 280-30
The 381, or SR1120SW, 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.Maxell Silver Oxide SR1120SW Low Drain Watch Battery Specifications
- Chemistry: Silver Oxide
- Nominal Voltage: 1.55V
- Nominal Capacity: 55mAh
- Nominal Discharge Current: 100 (�A)
- Diameter: 11.6 mm
- Height: 2.05 mm
- Weight: 1.0(g)
- 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.
