A battery refers to the part of a cup, tank or other container or composite container that holds an electrolyte solution and metal electrodes to generate electrical current and to convert chemical energy into electrical energy.

The performance parameters of the battery mainly include electromotive force, capacity, specific energy, and resistance. By using the battery as an energy source, people can get a long-term stable power supply and a current that is little affected by the outside world. The battery in modern society is simple in structure, easy to carry, easy to operate, not affected by external climate and temperature, and has stable performance, and is widely used in all aspects of modern social life.

AAA type battery

AAA batteries are also called 7 batteries. The volume of the 7th battery is smaller than that of the AA type (5th) battery. AAA batteries are generally used in remote controls, flashlights, etc., where the volume is limited, but the power consumption is not large.

AA type battery

AA batteries are also called 5 batteries. AA-type batteries are very common and are widely used in electric shavers, electronic toys, digital devices, and more. Many AA-type rechargeable batteries are also used as battery packs.

C type battery

The C-type battery is also called the No. 2 battery. The volume of the C-type battery is smaller than that of the D-type battery. Type C batteries are mostly used in flashlights and audio-visual equipment.

D type battery

The D-type battery is also called 1 battery. D-type batteries are also very common and are widely used in electronic ignition equipment, flashlights, and so on.

9V battery

9V batteries generally refer to laminated batteries. 9V batteries are generally used to power meters and measuring instruments. The battery capacity is small, the voltage is high, the internal chemical reaction is slow, the discharge current is small, and it can be used for a long time.

18650 battery

The 18650 battery has a large capacity per unit density and very good stability. Therefore, it is widely used in electronic fields, such as notebook computer batteries, portable instruments, industrial instruments, medical instruments, and so on.
