CR2477 battery

CR2477 battery

Among them, C-indicates the chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode, R-indicates that the shape of the battery is cylindrical, and if it is square, replace it with F;

24 means the diameter of the battery is 24.5mm, and 77 means the height of the battery is 7.7mm. The nominal voltage is 3.0V, the end point voltage is 2.0V, and the rated capacity is 850-1100mAh, depending on the level of the manufacturer. With the requirements of the new industry, there are also specially improved batteries, and their capacities will be very different, mainly to improve their high-current output capabilities, such as those used in smart control boards or RFID products.

The battery is often used in smart rice cooker control boards, IBEACON base stations, personnel positioning cards 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 batteries of domestic first-line brands can basically guarantee this life. If the use environment is very ideal (sealed, normal temperature, no interference such as moisture), its life will be further extended, up to 10 years.
