Can button battery cr1632 replace cr1620?

Cannot be substituted because the two different types of button cells are of different sizes.

The voltage of both button batteries is 3V, but the specifications are different and the capacity is different, depending on the product used.

The size and capacity of the two batteries:

(1) CR1620 size: 16.0 * 2.0MM, capacity: 70 mA

(2) CR1632 size: 16.0 * 3.2MM, capacity: 120 mA.

Extended information:

CR1620 is a button battery, and lithium manganese dioxide battery is a new type of high-performance chemical battery that has developed rapidly in recent years.

CR1620 uses a high-purity lithium metal sheet as the negative electrode, and uses a specific electrolytic manganese dioxide formula as the positive electrode. It has high voltage (above 3V), large capacity, small size, light weight, stable discharge voltage, safety and no pollution, and can be widely used Used in electronic watches, electronic desk calendars, calculators, computer motherboards, electronic toys, small electronic gifts and other low-power electronic appliances.

CR1632 is a 3V button-type manganese dioxide lithium battery, named after the IEC (International Electrotechnical Commission) naming standard. Among them, C- is a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode. CR- indicates that the shape of the battery is button-shaped, 16 indicates that the diameter of the battery is 16.0mm, and 32 indicates that the thickness of the battery is 3.2mm.
