The lithium-manganese dioxide battery is a disposable battery using lithium as an anode, manganese dioxide as a cathode, and an organic electrolyte.
The battery can be made in different shapes to meet different requirements. It has a rectangular shape, a cylindrical shape and a button shape (button type). Cylindrical also has different diameters and height dimensions. Here are the main parameters of the familiar 1# (size code D), 2# (size code C) and 5# (size code AA) batteries.
CR is represented by a cylindrical lithium-manganese dioxide battery; among the five digits, the first two digits indicate the diameter of the battery, and the last three digits indicate the height with one decimal.
It should be pointed out here that the parameters of the same type of battery produced by different factories may have some differences. In addition, the standard discharge current value is small, the actual discharge current can be greater than the standard discharge current, and the allowable discharge current for continuous discharge and pulse discharge is also different, and the battery manufacturer provides relevant data. For example, the CR14505 produced by Lisun Power Co., Ltd. gives a maximum continuous discharge current of 1000 mA and a maximum pulse discharge current of up to 2500 mA.
Most of the lithium batteries used in the camera are lithium-manganese dioxide batteries. The button type (button type) battery is small in size.
CR is a cylindrical lithium-manganese dioxide battery. The first two digits of the last four digits are the diameter dimensions of the battery, and the last two digits are the height dimensions with a decimal point. For example, CR1220 has a diameter of 12.5 mm (excluding the number after the decimal point) and has a height of 2.0 mm. This type of model representation is internationally accepted. This button battery is often used for clocks and calculations.
