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.

As a member of China's industrial instrumentation industry, Power Glory's products such as CR2477 and CR2032 are often used in industrial instruments such as flow meters, pressure sensors, liquid level meters, temperature and humidity recorders, etc.
