5. CR2477 Basic Information
Among them, C- represents a chemical battery system using lithium metal as a negative electrode and manganese dioxide as a positive electrode. R-indicates that the shape of the battery is a cylinder. If it is a square, F is substituted; 24 indicates that the diameter of the battery is 24.5 mm, and 77 represents a battery. The height is 7.7mm. The nominal voltage is 3.0V, the end point voltage is 2.0V, and the rated capacity varies from 850-1100mAh, depending on the manufacturer's level. With the requirements of the new industry, there are also special improvements in the battery, the capacity will be very different, mainly to improve its high-current output capabilities, such as applied to only control panel or RFID products.
The battery is often used in intelligent rice cooker control board, IBEACON base station, personnel positioning card and other products. The shelf life of CR2477 is usually 8 years. If the manufacturer's manufacturing level is not high or the quality control is not good, its life will be greatly shortened. The battery of the domestic first-line brand can basically guarantee this life. If the use of the environment is very good (sealing, room temperature, no water and other interference) its life will be further extended, up to 10 years.
