## Long description

Single Maxell BAT319.MX1 SR527SW silver oxide button cell with a nominal voltage of 1.55 V supplied as one piece. This compact cell provides stable output and low self-discharge, suitable for small electronic devices that require a consistent voltage in a miniature form factor. Designed to fit watch cases and other precision instruments that use SR527SW-sized cells, it offers reliable short-term power for timing, display and sensing functions.
Advantages
The silver oxide chemistry ensures a steady 1.55 V output over most of the discharge cycle and a flatter discharge curve compared with alkaline alternatives. Low self-discharge preserves capacity during storage, and the compact, standardized SR527SW size allows straightforward replacement in compatible devices. The single-piece supply is convenient for one-off repairs or small device maintenance where exact voltage and form factor are required.

How to use
Check the device manual or existing battery for the SR527SW size and 1.55 V rating before replacing.

Dispose of the spent battery according to local regulations for button cells and household batteries.
Usage recommendations
Store unused cells in a cool, dry place away from metal objects to avoid short circuits.
