Cr1620 is a kind of button battery. Lithium manganese dioxide battery is a new high-performance chemical battery developed rapidly in recent years. It uses high purity lithium sheet as negative electrode and electrolytic manganese dioxide as positive electrode. It has high voltage (above 3V), large capacity, small volume, light weight, stable discharge voltage, safety and no pollution. Can be widely used in electronic watches, electronic calendar, calculator, computer motherboard, electronic toys, small electronic gifts and other low-power electronic appliances. In the modern society which pays more and more attention to environmental protection, lithium battery is gradually replacing all kinds of 1.5V batteries with its excellent environmental protection and high performance, becoming the ideal small power supply in the new century.
