Murata CR2025 Battery

Key Specifications

• Nominal voltage: 3.0 V.

• Nominal capacity (to 2.0 V cutoff): ~ 160 mAh for the standard model.

• Dimensions: Diameter ≈ 20.0 mm, Height ≈ 2.5 mm.

• Weight: ~ 2.6 g (standard spec) for the Murata model.

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

• Operating temperature range (standard version): -30 °C to +70 °C.

 Features & Typical Applications

• Compact, 3 V coin-cell format that fits many small, low-current electronics (key fobs, watches, calculators, sensors, backup memory modules). For example, Murata lists applications like “Electronic Watch or Clock / Remote Controller / Electric Game, Toy / Memory Back-up Power Source for SRAM or Real Time Clock (RTC)”.

• Good energy density & long shelf life: The low self-discharge and stable voltage output make it suited for devices that may be dormant for extended periods. For example, Murata’s spec mentions that these coin manganese-dioxide lithium batteries have very low self-discharge (less than ~1% per year under normal storage for some models).

• Reliable for backup/standby power: Because of the stable voltage and long shelf life, the CR2025 is often used for real-time clocks, memory backup, and remote controls that don’t consume a lot of current but must remain powered over long times.
