3V CR2032 lithium manganese battery, belonging to the lithium - manganese dioxide structure, the cathode material selection of chemical properties of very stable manganese dioxide, anode material selection of metal lithium, the electrolyte is a solid salt or dissolved in organic solvents salts, such as buttons , Referred to as button lithium battery or lithium manganese button cell

lithiummanganese dioxideBattery, its name is named according to IEC standards. Which C-lithium metal as the negative, tomanganese dioxideFor the positiveChemical batterySystem, R- that the shape of the battery is cylindrical, if it is a square F alternative; 20 that the battery diameter is 20mm, 32 on behalf of the battery height of 3.2mm.QIs 3.0V, the end point voltage is 2.0V,Rated CapacityFor 200-230mAh range, depending on the level of manufacturers. With the new industry requirements, there are special improvements in the battery, its capacity will be very different, mainly to improve its high current output capacity, such as applied to flash or RF products. The battery is commonly used on computer motherboard CMOS batteries, other memory functions orPower protectionModule,Electronic scales, Calculator,Electronic dictionaryAnd other products.
note:
1, the correct connection of the battery "+" / "-" polarity; 2, different types of batteries do not use together; 3, do not directlysolderAdded to the battery; 4, to avoid the battery stored in theDirect light, High temperature, high humidity environment.
Shelf life
Usually the situation is 5 years of life if the manufacturer's manufacturing level is not high, orquality controlBad, its life will be greatly reduced. Domestic first-line brand of the battery can basically guarantee this life. Such as the use of the environment is ideal (sealed, room temperature, no water and other interference) its life will be further extended, up to 8 years, or even 10 years. Domestic lithiummanganese dioxideThe battery after several years of continuous improvement, performance has been closer to JapanBattery waterPing, especially the domestic first-line manufacturers, such as Jinde, letter Lake, Li Jia, Chi Pu, of course, there are a large part of the small factories do not do the production of low-end batteries, performance quality will be very different.
