## Long description

Silver oxide button cell Murata 377 (SR626SW) 1.55V is a primary coin-type battery intended for wristwatches and other compact electronic devices that require a stable voltage and dependable low-drain performance. The cell provides a nominal voltage of 1.55 V and is compatible with devices designed for SR626/SR66 sized batteries. Designed for long shelf life and consistent output during typical watch and small-electronics operation, this silver oxide chemistry ensures minimal voltage drop over the discharge period compared with alkaline alternatives.
Advantages
The Murata 377 (SR626SW) combines stable nominal voltage with low self-discharge, providing reliable timekeeping and consistent operation in small loads. Its silver oxide chemistry offers better voltage stability under steady, low-drain conditions, making it suitable for precision instruments such as analog and digital watches. The compact coin form factor fits standard SR626/SR66 housings and replacement slots, enabling straightforward installation in many consumer and medical devices.
Suitable for
Wristwatches (analog and digital)
Calculators and small electronic calculators
Small medical devices such as glucose meters and thermometers
Hearing aid remote controls and small remote controls
Small LED indicators, laser pointers, and compact sensors
Key specifications
Chemistry: Silver oxide (stable low-drain performance)
Nominal voltage: 1.55 V
Cell type: Button/coin cell
Size compatibility: SR626 / SR66 form factor
Intended use: Primary (non-rechargeable) battery for low-drain devices
Typical properties: Low self-discharge and consistent voltage under nominal loads
How to use
Install the cell in the device following the manufacturer’s polarity markings, ensuring the correct orientation (positive side typically marked) before closing the battery compartment. Use a clean, dry environment and avoid forcing the cell into the holder; the coin cell should seat snugly in the designated slot. Replace spent batteries promptly with the same type and size to maintain device performance. Dispose of used silver oxide cells according to local regulations for battery recycling or hazardous waste.
Usage recommendations
Store unused cells in a cool, dry place and avoid exposure to high temperatures or humidity to preserve shelf life. For optimal device performance, replace batteries before device malfunction occurs and do not attempt to recharge, disassemble, or heat the cells.
