Button cell battery Maxell BAT319.MX1 1.55V Silver Oxide SR527SW – single piece

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. Power the device off if possible, open the battery compartment carefully, and note polarity orientation. Insert the new silver oxide cell with the correct polarity, secure the compartment cover, and test the device operation. 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. For devices that require long-term continuous operation, consider the device's current draw and check manufacturer guidance to determine appropriate replacement intervals. Keep batteries out of reach of children and seek professional disposal or recycling options where available.
