    What are the types of batteries?

    2019-04-25 09:30:37 0

    1, carbon battery

    Primary battery, voltage: 1.5V

    Zinc-manganese battery, commonly known as carbon battery. Dry batteries commonly used in daily life. It is currently the cheapest battery. This battery has a low capacity and is easy to leak. Currently commonly used in TV remote control and other products. Common products: No. 1, No. 2, No. 5, No. 7, and buttons.


    2, alkaline battery

    Primary battery, voltage: 1.5V

    Alkaline batteries are currently the most commonly used batteries. The advantage is that the battery capacity is 7 times that of a carbon battery. The current output is stable and does not leak. It can be used in equipments with large power consumption. Common products: No. 1, No. 2, No. 5, No. 7, and buttons.


    3, nickel-cadmium battery

    Rechargeable battery, voltage: 1.2V

    Disadvantages of nickel-cadmium batteries: large volume, heavy weight, small capacity, self-discharge, memory effect, and environmental protection. The advantage is that it can be charged more than 500 times, which is very economical. It is resistant to overshoot and easy to use. The internal resistance is small and can discharge at a large current, so this product is often used in power tools. Common products: No. 1 (D type), No. 2 (Type C), No. 5 (AA), No. 7 (AAA), button type and various non-standard models.


    4, nickel-hydrogen battery

    Rechargeable battery, voltage: 1.2V

    A disadvantage of the nickel-hydrogen battery and the nickel-cadmium battery is that it cannot discharge at a large current (currently there is a nickel-hydrogen battery that produces a large current discharge in a factory). The advantage is that the same volume capacity is more than double that of nickel cadmium, the memory effect is small, and no pollution is called a green battery. Common products: No. 1 (D type), No. 2 (Type C), No. 5 (AA), No. 7 (AAA), button type and various non-standard models.


    5, lithium ion battery

    Voltage: 3.7V

    The lithium-ion battery case has a steel shell and an aluminum shell, and the aluminum shell has a capacity of 10% to -15% higher than that of the steel shell. Advantages: small volume, high capacity, and high voltage. The shape is cylindrical, square, and shaped. Often used in mobile phone batteries, PDA batteries, laptop batteries.


    6, lithium polymer battery

    Voltage: 3.7V

    Lithium polymer battery and lithium ion battery comparison: the outer packaging is aluminum plastic packaging, different from the metal shell of lithium ion. Thanks to the flexible packaging technology, a thinner battery can be produced. The shape can be changed at will. Light weight, higher capacity, low internal resistance and support for large current discharge. Common in high-end mobile phone batteries, laptop batteries, all kinds of power tools and model batteries.


    The No. 5, No. 7, No. 1, and No. 2 batteries in the battery model are the most commonly used in life. The AAA, AA, C, D, N, F, SC and other marks we see on the battery body are all US model marks.


    1, AAA type battery (7th battery)

    The 7th battery has a height of 44.0mm and a diameter of 10.0mm. It is used in remote controls, electric toothbrushes, cameras, radios, alarm clocks, wireless mice, children's electric toys, razors, etc., which are limited in size but not too large in power consumption. Occasionally, flashlights are also used, but most of them are used in combination.


    2, AA type battery (5th battery)

    This is the most common, with a height of 49.0mm and a diameter of 14.0mm. Electric shavers, electronic toys, digital devices, etc. are used the most, and many AA-type rechargeable batteries are also used for battery packs, especially for the 4.8V rechargeable four-section combination on toys.


    3, C type battery (2nd battery)

    The No. 2 battery head is smaller than the No. 1 battery, with a height of 49.5 mm and a diameter of 25.3 mm. Used in flashlights, toys, audio-visual equipment, gas stoves, water heaters are also useful.


    4, D type battery (No. 1 battery)

    This is the same as the No. 5 battery, with a height of 59.0mm and a diameter of 32.3mm. Electronic ignition equipment, flashlights, gas stoves, etc. can be used in many occasions.


    5, AAAA type battery (9th battery)

    The AAAA battery has a height of 41.5mm and a diameter of 8.1mm. Mostly used in some high-end electronic equipment, such as Bluetooth headsets, stylus.


    6, type A battery

    Type A batteries are generally used as battery packs, such as smart meters, gas meters, cameras, cameras, telephones, etc. Type A batteries are about the same height as No. 2 batteries, with a slightly smaller diameter, a height of 49.0 mm and a diameter of 16.8 mm.


    7, SC type battery

    The SC type battery is also generally used for stacking battery packs, with a height of 42.0 mm and a diameter of 22.1 mm.


    8, N-type battery

    N-type batteries are generally used as battery packs. Due to their small size, they are also used in electronic devices with limited volume, such as doorbells, with a height of 28.5 mm and a diameter of 11.7 mm.


    9, F-type battery

    The F-type battery is also used in the battery pack, and has a height of 89.0 mm and a diameter of 32.3 mm.


    10, other batteries

    23A (12V), 27A (12V), 10A (9V), 25A (9V), 6F22 (9V), F22 (6V), 11A (6V), 26A (6V), 476A (6V), 2X625A (3V), etc. Small square or cylindrical batteries are generally stacked by button batteries, and are often used in meters such as multimeters and smoke detectors.
