CR2032 lithium button battery nominal voltage of 3V, is 2 times the battery, which uses chemically very stable manganese dioxide as cathode materials and a very high specific energy lithium as the anode material. Self-discharge rate of less than 2%, long storage life. Sealed battery with reasonable structure and material, good air tightness, very safe to use. Lithium batteries have a wide temperature characteristics, in -20 ℃ - +60 ℃, the battery can work effectively stored for one year. Button batteries are widely used in electronic dictionary, camera, remote control, blood glucose tester, body fat tester, automotive tire pressure gauge, electronic scales, calendar, toys, watches, attendance, MP3, radio, electronic flash products. CR2032 Specification Nominal Voltage 3V Nominal capacity 210mAh Standard Current 0.2mA 2.0mA Maximum continuous current Maximum pulse current of 20mA maximum size Φ20.0x3.2mm weight 3.1g we can provide various types of cell processing on welding foot, lead, Siamese batteries, or processed into hanging card (chip) equipment, as well as providing other processing methods lithium manganese dioxide battery, and its name is based on the IEC standard naming which C-in lithium metal as the anode, manganese dioxide as cathode chemical battery system R-indicates that the battery is cylindrical in shape, a square if the F-substitution; 20 indicates that the battery has a diameter of 20mm, 32 represents the height of the battery is 3.2mm. Nominal voltage of 3.0V, the endpoint voltage (end point voltage) of 2.0V, nominal capacity of 200-230mAh range, because manufacturers level varies. With the new requirements of the industry, there are also special improved battery, its capacity will be very different, mainly to improve its high current output capability, such as flashing lights or RF products used.
