Product information

Description

SEIKO SR936SW (also referred to as 394 or 380) is a single silver-oxide button cell battery with a nominal voltage of 1.55V. Supplied individually, this compact cell is intended for precision devices that require a stable output and long shelf life. Its chemistry and construction are designed to deliver consistent voltage over the discharge period and to fit standard button-cell compartments in watches and small electronics.

Advantages

The silver-oxide chemistry ensures a steady voltage profile and relatively high energy density for its size, supporting reliable operation of timekeeping and measurement devices. The battery's compact button-cell form factor allows easy replacement in a wide range of small devices, and storage stability minimizes self-discharge during shelf life. Manufactured to watch-grade dimensions, it provides predictable fit and contact in compatible holders.

  • Медицинские приборы с низким энергопотреблением
  • Малые электронные устройства (например, пульты, датчики, игрушки с небольшой нагрузкой)

Key specifications

  • Chemistry: silver-oxide (AgO)
  • Nominal voltage: 1.55 V
  • Cell type: button / coin cell
  • Supply: single piece, pre-packaged
  • Typical applications: precision timekeeping and low-drain electronics

How to use

Install the SR936SW with correct polarity, observing the positive (+) and negative (–) markings on the device and battery. Use a non-metallic tool or plastic tweezers where possible to avoid shorting contacts during replacement. Ensure the battery compartment is clean and free of corrosion before inserting the new cell. After replacement, verify device function and close the compartment securely to maintain contact and environmental protection.

Usage recommendations

Store unused batteries in a cool, dry place away from direct sunlight and metal objects. Do not attempt to recharge, disassemble, short-circuit or expose the cell to fire. Keep out of reach of children and follow local regulations for battery disposal or recycling.
