  • Introduction:Basic Information: CR3032 is a lithium manganese coin cell battery that is non-rechargeable. It has a nominal voltage of 3V, a diameter of 30.0mm, a thickness of 3.2mm, and weighs approximately 6.8g. The standard current is typically between 0.2mA and 0.4mA, with a capacity ranging from 500mAh to 560mAh.
    Performance Features: This battery uses chemically stable manganese dioxide as the positive electrode material and lithium metal as the negative electrode material, with an annual self-discharge rate of less than 2%, ensuring a long storage life. It can operate normally within a temperature range of -20°C to 70°C, making it suitable for various environments. Additionally, its robust battery casing provides excellent sealing, effectively preventing leakage and ensuring safe and reliable use.
    Application Areas: CR3032 batteries are commonly used in car key remote controls, set-top boxes, computer motherboards, weighing scales, electronic dictionaries, calculators, watches, memory cards, electronic toys, LED lights, and utility meters such as water meters, electricity meters, and gas meters. They provide memory support or power supply for these devices.
