Murata CR 1620

• Nominal voltage: 3.0 V.

• Typical capacity: around ~75–80 mAh — e.g., 80 mAh listed on Murata’s lineup.

• Dimensions: Diameter ≈ 16.0 mm, Height ≈ 2.0 mm.

• Weight: approximately 1.2–1.3 g.

• Chemistry: Lithium / Manganese Dioxide (Li/MnO₂), non-rechargeable (primary) cell.

• Operating (standard) temperature range: around -30 °C to +70 °C for the standard Murata model.

• Very low self-discharge: < 1% per year under normal storage conditions.

 Applications

• The CR1620 provides a compact form factor (16 mm diameter × 2 mm thick) which makes it suitable for small electronic devices where space is limited.

• Because it uses lithium chemistry, it offers a stable 3 V output and good shelf-life making it ideal for low-to-moderate drain, long-term applications: for example watches, key fobs, calculators, memory backup, sensors.

• Murata’s “Coin Manganese Dioxide Lithium Batteries” lineup highlights “superior storage characteristics” (low self-discharge) and “superior leakage resistance” for their coin-cells.
