Panasonic CR2450 Battery 3V 345mAh Lithium Coin Cell

The Panasonic CR2450 Battery is a 3V lithium coin cell designed for compact electronic devices that require a stable, reliable primary power source. Panasonic's CR2050 high-temperature series provides a 24 mm diameter, 5 mm height, and 345 mAh nominal capacity, making it suitable for applications where compact size and dependable long-term power are important.

The CR2450 is a non-rechargeable primary lithium battery and should not be recharged. It is suitable for electronics projects, embedded systems, meters, automotive electronics, IoT equipment, backup power applications, and other low-power electronic devices where the equipment specifically supports a CR2450-size 3V lithium cell.

Panasonic's CR2450A high-temperature version operates from -40°C to +125°C, while the CR2450B2 version is specified from -40°C to +120°C. Panasonic identifies applications including TPMS, ETC systems, meters, and other electronics requiring reliable operation across a wide temperature range.

For Bangladeshi electronics students, engineers, technicians, and makers, the Panasonic CR2450 can be useful when designing compact battery-powered circuits, RTC/backup-power systems, measurement equipment, embedded electronics, and IoT devices.

Always check the original equipment manufacturer's battery specification before replacing another battery with a CR2050.

CR2450 vs CR2032

CR2450 and CR2032 are both 3V lithium coin-cell families, but their physical dimensions are different. A CR2050 is 20mm in diameter and 5mm thick, whereas a CR2032 is 20mm in diameter and 3.2mm thick. Therefore, a CR2050 should not automatically be considered a drop-in replacement for a CR2432. Panasonic's battery handbook lists CR2032 and CR2050 as separate models with different dimensions and capacities.

Important Safety Information

• Do not recharge the CR2450.
• Do not short-circuit the battery.
• Do not disassemble, crush, puncture, or expose it to fire.
• Install the battery with the correct polarity.
• Keep coin-cell batteries away from children.
• Dispose of used batteries according to local battery-recycling or waste-disposal requirements.
• Confirm the exact battery model and terminal configuration before installation.

Panasonic specifically warns that swallowed coin batteries can cause serious harm and should be kept away from children.
