What is a CR2450 Battery?

CR2450 Battery

In terms of size and capacity, the CR2450 battery is among the largest lithium coin cells. With a long shelf life and a stable voltage output, the CR2450 makes use of lithium chemistry like other CR series batteries. A “CR” designation indicates that it is composed of lithium manganese dioxide, a mineral with excellent energy density and reliability. Despite its dimensions, the “2450” battery is larger than many other coin cells, with a diameter of 24 millimeters and a thickness of 5.0 millimeters.

CR2450 batteries are preferred by devices requiring greater power and longer operating times because of their larger size and higher capacity. Many devices such as medical devices, keyless entry systems, watches, and other electronic gadgets use this technology. Because of its larger capacity, the CR2450 is suitable for powering devices that require more power, resulting in longer battery life between replacements. Consumers and manufacturers alike are choosing this power supply for their electronic devices because of its wide availability and compatibility.
