Button cell battery MAXELL BAT321.MX1 SR616SW 1.55V Silver Oxide

MAXELL BAT321.MX1 SR616SW 1.55V Silver Oxide is a button cell battery engineered to deliver stable voltage and reliable performance for small electronic devices. This SR616SW-sized silver oxide cell offers a nominal voltage of 1.55V and is intended for low-drain and intermittent-use applications where consistent power and long shelf life are important. The battery is compatible with devices that accept SR616SW dimensions and output characteristics.

Advantages

The silver oxide chemistry provides a steady voltage output throughout most of the battery's discharge cycle, which helps maintain accurate operation of timekeeping and precision devices. Its compact button cell form factor fits common watch and instrument battery compartments. The construction is designed for low self-discharge, enabling reliable storage and long standby life when not in use. The cell's stable performance under varying temperatures supports predictable behavior in consumer and medical electronics.

Suitable for

• Wristwatches and pocket watches
• Calculators and small electronic measuring tools
• Hearing devices and medical instruments with low-drain requirements
• Remote controls, key fobs and small sensors
• Replacement for devices specifying SR616SW / equivalent size

How to use

Install the battery with the correct polarity as indicated in the device compartment, ensuring the positive (+) and negative (–) terminals align with the device contacts. Use a non-metallic tool or clean, dry fingers to place the cell into position to avoid shorting. After insertion, confirm the device functions correctly and close the battery cover or compartment according to the device manufacturer's instructions. Replace the cell when device performance degrades or the manufacturer recommends scheduled replacement.

Usage recommendations

Store unused batteries in a cool, dry place away from direct sunlight and metal objects. Keep out of reach of children and pets. Do not recharge, disassemble, crush, short-circuit, or dispose of in fire. Dispose of used batteries according to local regulations and recycling guidelines for button cells.
