Product information

Description

Single SEIKO SR726SW (type 397) silver-oxide button cell battery, nominal voltage 1.55 V, supplied as one piece. Designed to deliver stable voltage and predictable discharge characteristics for small precision devices, this cell is commonly used as a direct replacement in compatible watches, calculators, medical instruments and other compact electronics that require consistent power over extended periods.

Advantages

The SR726SW silver-oxide chemistry offers a stable 1.55 V output with low self-discharge, providing reliable performance over its recommended service life. Its compact button-cell form factor ensures compatibility with devices built for SR726SW/397 dimensions. Silver-oxide construction yields better voltage stability under load compared with alkaline alternatives, which supports accurate timekeeping and consistent operation in sensitive instruments.

How to use

Before installation, confirm device compatibility with SR726SW/397 batteries by checking the device manual or existing battery marking. Insert the battery with correct polarity, ensuring the plus (+) side faces the indicated terminal in the battery compartment. Close the compartment securely and verify device operation. Replace batteries in pairs or as recommended by the device manufacturer where multiple cells are used. Dispose of the spent battery according to local regulations for battery recycling or collection points.

Usage recommendations

Store unused batteries in a cool, dry place away from metal objects and extreme temperatures. Avoid short-circuiting, disassembling or exposing the cell to fire. For devices that require consistent timekeeping or medical measurements, replace the battery at the first sign of reduced performance to maintain accuracy.
