Murata CR 2450 Battery

Key Specifications

• Nominal voltage: 3.0 V.

• Nominal capacity: ~ 610 mAh (when discharged to about 2.0 V under light load) for the standard version.

• Dimensions: Diameter ≈ 24.5 mm, Height ≈ 5.0 mm.

• Weight: Approximately ~ 6.5 g.

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

• Operating temperature (for the standard version): about -30 °C to +70 °C

• Storage / Self-discharge: Very low self-discharge — less than about 1 % per year under normal storage conditions for some Murata coin cells

 Features

• High energy density in a coin format: The 610 mAh capacity is quite high for a 24.5×5 mm coin cell, making it suitable for applications needing longer life.

• Stable power supply: The 3 V output and good discharge characteristics ensure reliable performance over time, which is important for devices like memory backup modules or IoT sensors.

• Compact but capable: Because it’s a fairly large coin cell, devices that have space for 24.5 mm diameter × 5 mm height can take advantage of this.

• Long shelf life & reliability: With low self-discharge and robust construction (good leakage resistance claimed) it’s a good choice for standby/backup power.

• Common applications: According to Murata’s datasheet, uses include memory backup (SRAM/RTC), IoT tags, smart transmitters, keyless entry, sensors.
