Coin cell battery Vinnic CR1620 lithium 3V, single piece

Vinnic CR1620 lithium 3V coin cell battery supplied as a single piece is a compact power source sized for devices that use 1620-format cells. The cell delivers a nominal 3 volts and is intended for low-drain applications where long shelf life and steady voltage are required. The CR1620 form factor fits many watches, small calculators, key fobs, sensor modules and other compact electronics that call for a 16 mm diameter, 2.0 mm thickness lithium coin cell.

Advantages

This Vinnic CR1620 coin cell offers stable 3V output and an extended shelf life typical of lithium chemistry, enabling reliable operation in devices with low continuous or intermittent current draw. Its compact dimensions make replacement straightforward in tight housings. Supplied as a single piece, the battery is convenient for one-at-a-time maintenance or replacement without bulk packaging. The lithium cell is lightweight and resistant to discharge at moderate temperatures, providing predictable performance for timekeeping and memory backup functions.

Suitable for

• Wristwatches and small timepieces
• Key fobs and remote controls
• Calculators and small electronic toys
• Medical devices with low-drain requirements (e.g., glucose meters, thermometers)
• Sensor modules and memory backup in compact electronics

Key specifications

• Chemistry: lithium manganese dioxide (Li-MnO2)
• Nominal voltage: 3.0 V
• Size: 16.0 mm diameter × 2.0 mm thickness
• Form factor: coin / button cell (CR1620-compatible)
• Typical applications: low-drain devices, backup power, timekeeping
• Storage: long shelf life when stored in a cool, dry place

How to use

Before installation, verify the device requires a CR1620-size 3V lithium cell and observe polarity markings on the battery and device. Use a suitable tool or follow the device manufacturer’s instructions to open the battery compartment, avoiding metal tools that could short the cell. Insert the cell with the correct orientation, usually the positive (+) side facing up, then close the compartment securely. Dispose of the old battery according to local regulations for lithium coin cells and avoid exposing the cell to extreme heat or direct flame.

Usage recommendations

Store unused batteries in their original packaging at room temperature in a dry place. Do not recharge, disassemble, deform or short-circuit the battery. Replace with the same type and size to ensure compatibility and safe operation.
