Lithium battery CR 2450 piles

The CR2450 is a 3V lithium-manganese dioxide coin cell battery designed for low-power electronics requiring long-term operation. Measuring 24.5 mm in diameter and 5.0 mm in thickness, it provides a nominal capacity of approximately 620 mAh, offering significantly more energy than smaller variants like the CR2032. This battery is typically used to power microcontroller boards, wireless modules, sensors, and real-time clock circuits in embedded systems and maker projects.
