Button Battery CR1220
CR1220CR1220-3V lithium manganese button battery, also known as lithium metal battery, is a disposable battery (primary battery). Its high voltage, high energy density, wide operating temperature range, excellent discharge stability and safety make it widely used in low-power electrical products. Its single cell voltage is 3V, which is twice that of zinc-manganese button battery.
CR1220 batteries are often used in smart homes, medical equipment, such as thermometers, LED light-emitting holiday toys, RTC circuits and other products as the main power supply or memory support power supply.
