Button cell battery Voltcraft CR2016 3V 80mAh lithium coin cell

Voltcraft CR2016 is a 3V lithium coin cell designed for compact electronic devices where reliable, low-drain power is required. The cell delivers a nominal voltage of 3 volts and a typical capacity of 80 mAh in a thin, flat package compatible with many button battery compartments. It is intended for use as a replacement or spare battery in devices that demand steady voltage over long storage periods and intermittent use.

Advantages

The battery provides a stable 3V output with a capacity suited to low-current applications, delivering consistent performance over long shelf life. Its compact coin-cell form factor allows easy installation in shallow battery holders. The lithium chemistry offers low self-discharge and reliable operation in a wide temperature range, making it suitable for devices that remain in standby for extended periods.

Suitable for

• Wristwatches and small timepieces
• Key fobs and remote controls
• Calculators and small electronic toys
• CMOS/RTC backup on motherboards and embedded systems
• Medical devices with low continuous drain (e.g., glucose meters)

Key specifications

• Chemistry: lithium (non-rechargeable)
• Nominal voltage: 3 V
• Typical capacity: 80 mAh
• Cell type: button/coin cell
• Form factor: thin, flat disc suitable for standard CR2016 holders
• Intended use: low-drain and standby applications

How to use

Insert the cell into the device’s battery compartment observing polarity markings: the positive (+) side typically faces up. Ensure the contact surfaces are clean and free of corrosion before installation. Replace depleted cells with the same type and nominal voltage to maintain device performance. Dispose of used batteries according to local regulations for lithium batteries or return them to designated recycling points.

Usage recommendations

The battery is intended for replacement in low-drain devices; avoid using it in high-drain applications or attempting to recharge it. Store unused batteries in a cool, dry place away from metal objects to prevent short-circuiting and to preserve shelf life. Keep out of reach of children and follow safety instructions provided by device manufacturers.
