What is the type and voltage of dry battery?

Classification of dry battery types 1. Our country is named according to international conventions. The types of cylindrical batteries are classified as: AAA, AA, A, SC, C, D, F, a total of seven types. 2. AA is what we usually call No. 5 battery, Japan is called 単3 shape, the general size is: height 48.0±0.5mm, diameter 14.1mm±0.2mm; and AAA is what we usually call No. 7 battery, Japan is called the singular shape, the general size is: height 43.6mm ± 0.5mm, diameter 10.1mm ± 0.2mm. 3. It is not common to use only one A to indicate the type of battery. This series is usually used as the battery cell in the battery pack. The nickel-cadmium and nickel-metal hydride batteries of old cameras are almost 4/5A or 4/5SC battery cells. Standard A (flat head) battery general size: height 49.0±0.5mm, diameter 16.8±0.2mm. 4. SC models are not common. They are usually the battery cores in battery packs. They are mostly found on power tools, cameras and imported equipment. The standard SC (flat head) battery has a height of 42.0±0.5mm and a diameter of 22.1±0.2mm. 5. Model C is the second battery. The standard C (flat head) battery has a height of 49.5±0.5mm and a diameter of 25.3±0.2mm. 6. The D model is the No. 1 battery, which has a wide range of uses. D-type batteries can be found in civilian, military, and special-type DC power supplies. The standard D (flat head) battery has a height of 59.0±0.5mm and a diameter of 32.3±0.2mm. 7. Model F battery is a new generation product of power lithium battery, which has a tendency to replace lead-acid maintenance-free battery, and it is generally used as battery core. The standard F (flat head) battery has a height of 89.0±0.5mm and a diameter of 32.3±0.2mm. What is the voltage of the dry cell? The voltage of dry battery is divided into open circuit voltage, working voltage, termination voltage and standard voltage. 1. Open circuit voltage: refers to the voltage of a dry battery in a non-working state. At this time, there is no current flowing. When the battery is fully charged, the potential difference between the positive and negative poles of the battery is usually above 1.6V, and the high can reach 1.725V; 2. The open circuit voltage corresponds to the working voltage, that is, the voltage of the dry battery in the working state. At this time, there is current flowing. Because the internal resistance when the current flows is to be overcome, the working voltage is always lower than the voltage at full charge; 3 , Termination voltage: that is, the battery should not continue to be discharged after it is placed at a certain voltage value. It is determined by the structure of the dry cell. The voltage of the dry cell when the discharge is terminated is 0.9V. 4. Standard voltage: In principle, the standard voltage is also called the rated voltage, which refers to the standard value of the potential difference caused by the chemical reaction of the positive and negative materials of the battery. The rated voltage of the dry battery is 1.5V. It can be seen that the standard voltage is the standard work. Voltage.
