Button cell battery Voltcraft CR1616 3V 50mAh lithium coin cell for watches and electronics

Voltcraft CR1616 is a 3V lithium button cell with a nominal capacity of 50mAh designed for small, low-drain electronic devices. The coin-cell format offers compact dimensions and a stable output voltage, suitable for applications such as wristwatches, remote controls, key fobs, calculators and various small electronic instruments. The cell’s chemistry and construction provide extended shelf life and reliable performance during intermittent use.

Advantages

The battery delivers a consistent 3V output and a rated capacity of 50mAh in a compact coin-shaped package, allowing straightforward replacement in devices requiring CR1616 cells. Its low self-discharge rate extends usable life in storage, while the lithium chemistry provides better energy density and temperature performance compared with alkaline button cells. The standardized dimensions ensure compatibility with devices specifying the CR1616 form factor.

Suitable for

• Wristwatches and small timepieces
• Key fobs and car remotes
• Calculators and small handheld electronics
• Medical devices with low power requirements (e.g., glucose meters, thermometers) where CR1616 is specified
• Backup memory and real-time clock modules in consumer electronics

How to use

Install the cell with correct polarity as marked in the device battery compartment, taking care to match the positive (+) and negative (–) orientations. Use appropriate tools or a non-metallic fingernail to avoid shorting contacts during replacement. After installing, check device functionality and ensure the battery fits securely in the holder without excessive force. Dispose of used button cells according to local regulations for battery recycling or hazardous waste.

Usage recommendations

Store unused batteries in a cool, dry place away from direct sunlight and heat sources. Avoid mixing new and used cells or different battery chemistries in the same device. Keep batteries out of reach of children and seek immediate medical attention if a battery is swallowed or inserted into the body.
