Button cell battery Maxell SR712SW 1.55V Silver Oxide — single piece

Maxell SR712SW 1.55V Silver Oxide — single piece is a compact button cell battery designed to deliver stable voltage for small electronic devices. This single-piece silver oxide cell provides a nominal voltage of 1.55 V and is intended as a replacement for devices that require SR712SW or equivalent sizes. The chemistry and construction prioritise consistent output and low self-discharge to maintain device performance over long periods of storage and intermittent use.

Advantages

The silver oxide chemistry ensures a flat discharge curve and reliable voltage stability, which helps connected devices maintain accurate timing and consistent operation. Low self-discharge characteristics allow the battery to retain capacity during shelf storage, reducing the need for frequent replacements. The small, standardised form factor makes it compatible with a wide range of watches, calculators, medical instruments and other compact electronics that accept SR712SW or equivalent cells.

Suitable for

• Wristwatches and pocket watches
• Calculators and small electronic measuring tools
• Medical devices such as glucometers and hearing aids that accept this size
• Small LED indicators, toys and remote controls with compatible battery holders

Key specifications

• Chemistry: Silver oxide
• Nominal voltage: 1.55 V
• Form factor: Button cell (small, coin-shaped)
• Single-piece supply: one cell per package
• Low self-discharge suitable for long shelf life

How to use

Before installation, ensure the device is powered off if possible and that the battery compartment is clean and free of corrosion. Observe correct polarity when inserting the cell: the flat positive side (+) typically faces outward according to the device markings. Press the battery into the holder until it is seated securely, making sure not to force or deform the holder. After replacement, confirm the device operates correctly and close the compartment. Dispose of the spent battery according to local regulations for battery recycling.

Usage recommendations

Store unused batteries at room temperature in a dry place away from direct sunlight and metal objects. Replace batteries in devices used for timekeeping or medical measurement promptly when performance drops, and avoid mixing new and used cells in the same device.
