CR2450 Battery
Also known as: Lithium coin cell
High-capacity coin cell designed for applications requiring longer runtime or higher current draw than standard CR2032. The larger size provides approximately 3x the capacity of CR2032. Popular in devices with LCD displays or periodic high-current pulses.
