What are the types of batteries?

1. Carbon batteries
Primary battery, voltage: 1.5V
Zinc-manganese battery, commonly known as carbon battery. Dry batteries are commonly used in daily life. It is the cheapest kind of battery at present. The battery has low capacity and leaks easily. At present, it is commonly used in TV remote control and other products. Common products: No. 1, No. 2, No. 5, No. 7, button type, etc.


2. Alkaline batteries
Primary battery, voltage: 1.5V
Alkaline batteries are the most commonly used batteries at present. The advantage is durable power, which can be 7 times as much as that of carbon batteries. The current output is stable, no leakage. It can be used in instruments and equipment with large power consumption. Common products: No. 1, No. 2, No. 5, No. 7, button type, etc.
3. Nickel-cadmium batteries
Rechargeable battery, voltage: 1.2V
The disadvantages of nickel-cadmium batteries are large volume, heavy weight, small capacity, self-discharge, memory effect and environmental protection. The advantage is that it can recharge more than 500 times, which is very economical. It can resist over-impact and over-discharge and is easy to use and operate. Because of its small internal resistance and high current discharge, this product is commonly used in the reuse of electric tools. Common products: No. 1 (D), No. 2 (C), No. 5 (AA), No. 7 (AAA), button and various non-standard models.
4. Nickel-hydrogen batteries
Rechargeable battery, voltage: 1.2V
Compared with nickel-cadmium batteries, nickel-hydrogen batteries have the disadvantage of not being able to discharge at high current (there are already factories producing nickel-hydrogen batteries with high current discharge). The advantages are that the same volume capacity is more than twice as high as nickel and cadmium, and the memory effect is small. The pollution-free battery is called green environmental protection battery. Common products: No. 1 (D), No. 2 (C), No. 5 (AA), No. 7 (AAA), button and various non-standard models.
5. Lithium-ion batteries
Voltage: 3.7V
The shell of lithium ion battery has steel shell and aluminium shell. The capacity of aluminium shell is 10%-15% higher than that of steel shell. It has the advantages of small volume, high capacity and high voltage. The shape is cylindrical, square and irregular. Usually used in cell phone batteries, PDA batteries, laptop batteries.
6. Lithium Polymer Batteries
Voltage: 3.7V
Lithium polymer batteries and lithium ion batteries: Aluminum plastic packaging, different from the metal shell of lithium ion. Because of the use of flexible packaging technology, thinner batteries can be produced. The shape can be changed at will. Lightweight, high capacity, low internal resistance, support high current discharge. Common in high-end mobile phone batteries, notebook batteries, all kinds of power tools and model batteries.


Batteries No. 5, No. 7, No. 1 and No. 2 are the most commonly used batteries in life. The AAA, AA, C, D, N, F, SC and other labels we see on the battery body are all American model labels.
1. AAA Battery (No. 7 Battery)
The size of battery No. 7 is 44.0 mm and its diameter is 10.0 mm. It is mostly used in remote control, electric toothbrush, camera, radio, alarm clock, wireless mouse, children's electric toys, shaver and other occasions with limited volume but not too much power consumption. The torch is also used, but mostly in combination.
2. AA Battery (No. 5 Battery)
This is the most common one. The size is 49.0 mm in height and 14.0 mm in diameter. Electric shaver, electronic toys, digital equipment and so on are most used. Many AA rechargeable batteries are also used as battery packs, especially the 4.8V rechargeable four-section combination of toys.
3. Type C Battery (No. 2 Battery)
The size of No. 2 battery is smaller than that of No. 1 battery. Its size is 49.5mm and its diameter is 25.3mm. It is widely used in flashlights, toys, audio-visual equipment, gas stoves and water heaters.
4. D Battery (No. 1 Battery)
This is the most used battery like No. 5, with a height of 59.0 mm and a diameter of 32.3 mm. Electronic lighting equipment, flashlights, gas stoves and many other occasions can be used.
5. AAAA Battery (No. 9 Battery)
AAAA battery size height 41.5mm, diameter 8.1mm. Most of them are used in some high-end electronic devices, such as Bluetooth headset, handwritten pen.
6. Type A Batteries
Type A batteries are generally used as battery packs, such as smart meters, gas meters, cameras, cameras, telephones, etc. Type A batteries are similar in height to type 2 batteries, with slightly smaller diameter, 49.0 mm in height and 16.8 mm in diameter.
7. SC battery
SC-type batteries are also commonly used for stacking batteries, with a height of 42.0 mm and a diameter of 22.1 mm.
Type 8 and N Batteries
N-type batteries are generally used as batteries. Because of their compact size, they can also be used in electronic devices with limited volume, such as doorbells, with a size of 28.5mm and a diameter of 11.7mm.
9. F Battery
F-type batteries are mostly used in batteries with a size of 89.0 mm and a diameter of 32.3 mm.
10. Other batteries
Small square or cylindrical batteries, such as 23A (12V), 27A (12V), 10A (9V), 25A (9V), 6F22 (9V), F22 (6V), 11A (6V), 26A (6V), 476A (6V), 2X625A (3V), are usually stacked by button batteries and are mostly used in multimeter, smoke sensor and other instruments.
