CR2477 battery voltage is 3.0V, capacity 1000, Size 24.5X7.7mm, weight 10.0g manganese button batteries are widely used in computer motherboards, electronic dictionary, camera, remote control, ear thermometers, blood glucose tester, body fat tester, automotive tire pressure gauge, electronic scales, calendar, toys, watches, attendance, MP3, radio, electronic flash products. Lithium button battery nominal voltage 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 -40 ℃ - +60 ℃, the battery can work effectively stored for one year. We can provide various types of cell processing on welding foot, lead, twin batteries, or processed into hanging card (chip) equipment, as well as provide other processing methods.
