Wanzhow Lithium Cell CR2025 3V Coin Cell For CMOS Electronics Calculator Watch Remotes Battery  (Pack of 5)

Type: The "CR" in CR2025 stands for the chemical composition of the battery, which is lithium manganese dioxide. Size: The "2025" in CR2025 refers to the battery's size. It is 20mm in diameter and 2.5mm in height. It is a relatively small and thin battery. Voltage: The CR2025 battery has a nominal voltage of 3 volts. This voltage is suitable for powering various low-power devices, such as watches, calculators, remote controls, and small electronic gadgets. Capacity: The capacity of a CR2025 battery typically ranges from around 150 to 170 milliampere-hours (mAh). This capacity determines how long the battery can power a device before it needs replacement. Chemistry: As mentioned earlier, it uses a lithium manganese dioxide chemistry, which provides a stable and reliable power source. Common Applications: CR2025 batteries are commonly used in a wide range of small electronic devices, including watches, calculators, key fobs, remote controls, medical devices, and various small gadgets. They are also used in some computer motherboards to power the CMOS (Complementary Metal-Oxide-Semiconductor) memory, which stores system settings and the real-time clock. Long Shelf Life: One of the advantages of lithium coin cell batteries like the CR2025 is their long shelf life. They can hold their charge for several years when stored properly.
