The Internet of Things is the third revolution in the information technology industry. With the accelerated development of 5G and AI intelligent technologies, more and more professional IoT devices are becoming civilian and consumer products. The rapid popularization has led to a surge in the demand for button batteries in many sensor devices. Radio frequency identification, infrared sensors, global positioning systems, laser scanners and other information sensing devices all require button batteries, generally using CR2016, CR2032, CR2025, CR2032 and other models of button batteries.

Electronic watches are more accurate, stable and convenient than mechanical watches. Batteries are the energy source of electronic watches. There are many types of watch batteries, but there are three main types commonly used: CR2025, CR2032 and CR2016. When the power of the electronic watch is low, the battery should be replaced in time to avoid affecting normal use.
