Murata CR 2016

Key Specifications

• Nominal voltage: 3.0 V.

• Typical nominal capacity: ≈ 90 mAh (when discharged to 2.0 V) for the standard version.

• Dimensions: Diameter ≈ 20.0 mm, Height ≈ 1.6 mm.

• Weight: Approx. 1.8 g.

• Chemistry: Lithium manganese dioxide (Li/MnO₂) — a primary (non-rechargeable) cell.

• Operating temperature range: approx. -30 °C to +70 °C for the standard version.

 Features & Typical Applications

• Very compact and thin form makes it ideal for small-electronic devices requiring a long-life standby power source.

• Low self-discharge: Murata states that the coin manganese-dioxide lithium batteries have less than 1% self-discharge per year under normal storage conditions.

• Reliable 3 V output, long shelf life, good leakage resistance. For example, Murata describes: “Excellent discharge characteristics”, “Excellent leakage resistance”, “Excellent long-term reliability”.

• Common applications: watches, calculators, key fobs, memory backup (SRAM/RTC), IC cards, remote controllers, small sensors.
