Dry battery model

Dry battery knowledge battery model begins, the battery is a primary battery, the main ordinary manganese dry battery and the alkaline manganese batteries, battery type identification that is a parameter that identifies the two, it can be said to The initial understanding of dry batteries is based on an expression of the dry cell size parameter, which in practice is performed by battery identification.

Note: In the IEC standard, R stands for cylindrical shape, L stands for alkaline, the number represents the size of the battery, and the P after the number stands for high power. There is a special regulation here. When it indicates the ordinary zinc-manganese battery No. 5, it should be identified as R6P, instead of R06 or R6.

The CR series is also a typical dry battery model, and the common ones are CR2025, CR2032 and so on. Where C is a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode, R indicates that the shape of the battery is cylindrical, if it is square, F is replaced; 20 indicates that the diameter of the battery is 20 mm, and 32 represents the height of the battery. 3.2mm.

In addition to the name of a single dry battery model, there are some combinations of dry battery models identified as follows: 1,

9V battery: 6F22 is a carbon battery assembled by 6 flat cells; 6LR61 is composed of 6 flat battery stacks Alkaline battery;

2, AG series: is a small diameter CR battery, divided into 13 kinds of AG1 to AG13, belonging to alkaline batteries; 3,

23A and 27A: is composed of eight AG batteries of the same specification Also known as 12V button battery, 27A is greater than 23A.

The dry battery models of these combinations are often based on special voltage or capacity considerations and are only available in certain areas. Since these dry battery models have a certain market capacity, knowing that they belong to the dry battery sequence, it is easy to grasp the price and characteristics.

In addition, there are non-zinc manganese and lithium manganese based dry batteries, such as magnesium-manganese batteries, etc., because it is relatively rare, so there are not many models for such dry batteries and dry batteries.
