Introduction of various types of batteries

1. Generally divided into: 1, 2, 3, 5, and 7, of which No. 5 and No. 7 are especially commonly used. The so-called AA battery is the No. 5 battery, and the AAA battery is the No. 7 battery! AA and AAA are all explanatory batteries Model. 2. AA is what we usually call the No. 5 battery, the general size is: diameter 14mm, height 49mm; AA battery is well known, digital cameras, electric toys, AA batteries are indispensable, standard AA (flat head) The battery height is 48.0u0026plusmn;0.5mm, and the diameter is 14.1±0.2mm. 3. AAA is what we usually call the No. 7 battery, the general size is: diameter 11mm, height 44mm. AAA batteries are more common. The general MP3 uses AAA batteries. The standard AAA (flat head) battery has a height of 43.6±0.5mm and a diameter of 10.1±0.2mm. 4. AAAA models are rare, and disposable AAAA Energizer alkaline batteries can occasionally be seen, and they are generally used in computer pens. The standard AAAA (flat head) battery has a height of 41.5±0.5mm and a diameter of 8.1±0.2mm. 5. There is only one A, which means that the type of battery is not common. This series is usually used as the battery cell in the battery pack. I often replace the nickel-cadmium and nickel-metal hydride batteries of old cameras. Almost all are 4/5A or 4/5SC. Of battery cells. The standard A (flat head) battery has a height of 49.0±0.5mm and a diameter of 16.8±0.2mm. 6. The SC model is also not common. It is usually the battery cell in the battery pack, which can be seen 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. 7. Model C is the second battery, which has many uses. The standard C (flat head) battery has a height of 49.5±0.5mm and a diameter of 25.3±0.2mm. 8. 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. 9. The N model is not common. I still don't know what is used in it. The standard N (flat head) battery has a height of 28.5±0.5mm and a diameter of 11.7±0.2mm. 10. F-type batteries are now a new generation of electric bicycles and power lithium batteries. They have a tendency to replace lead-acid maintenance-free batteries. They are generally used as battery cells. (Personal opinion: In fact, they are too big to be used alone. Ha ha). The standard N (flat head) battery has a height of 89.0±0.5mm and a diameter of 32.3±0.2mm. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
