Button cell battery MAXELL SR41SW (Silver Oxide) 1.55V — single piece

Single MAXELL SR41SW button cell battery with silver oxide chemistry delivers a nominal voltage of 1.55V in a compact form factor suitable for precision small electronics. This single-piece battery is intended for devices that require stable voltage and low self-discharge, offering consistent performance for timekeeping, small displays and sensor circuits. The battery format corresponds to common watch and instrument sizes and is compatible with devices designed for SR41/392 type silver oxide cells.

Advantages

The silver oxide chemistry provides a stable 1.55V output and a relatively flat discharge curve that helps maintain consistent operation of watches, calculators and medical instruments. Low self-discharge ensures long shelf life while compact dimensions allow use in tightly packaged devices. Single-piece packaging makes it easy to replace individual cells without buying multi-packs.

Suitable for

• Wristwatches and pocket watches
• Calculators and small electronic displays
• Thermometers and digital kitchen instruments
• Medical devices such as glucose meters and hearing devices specified for SR41/392 size
• Small sensors, key fobs and remote controls requiring 1.55V silver oxide cells

Key specifications

• Chemistry: silver oxide
• Nominal voltage: 1.55 V
• Form factor: button cell compatible with SR41/392 size devices
• Typical use: low-drain precision electronics
• Packaging: single piece

How to use

Ensure the device is powered off or in a safe state for battery replacement. Use a suitable battery removal tool or a small non-metallic implement to avoid shorting contacts when extracting the old cell. Observe correct polarity when inserting the new MAXELL SR41SW battery, matching the positive side to the device’s marked terminal. After installation, verify device operation and securely close the battery compartment to prevent contact displacement.

Usage recommendations

Store batteries in a cool, dry place away from direct sunlight and heat sources. Keep out of reach of children and dispose of used button cells according to local regulations for battery recycling. Do not attempt to recharge, disassemble, puncture or incinerate silver oxide button cells. If a device shows signs of leakage or corrosion, remove the battery carefully and clean contacts before installing a new cell.
