The 18650 is only the size and model of the battery. According to the battery type, it can also be divided into 18650 for lithium ion, 18650 for lithium iron phosphate, 18650 for nickel hydride (rare). The common 18650 is lithium ion. 18 means the diameter is 18mm, 65 means the length is 65mm, and 0 means the cylindrical battery. Common 18650 batteries are divided into lithium ion batteries and lithium iron phosphate batteries. The voltage of lithium ion battery is 3.6V and 4.2V, the voltage of lithium iron phosphate battery is 3.2V, the capacity is generally 1200MAH-3000MAH, and the common capacity is 2200mAh to 3600mAh.

Uses of 18650 lithium battery:

1. The life theory of 18650 lithium battery is more than 500 cycles of charging. It is commonly used in high light flashlights, headlights, mobile medical equipment, etc.

2. It can also be combined. There is also a difference between a plate with and without a plate. The main difference is that the protection of the plate with a plate is over discharge, over discharge, and over current value to prevent the battery from being discarded due to outdated charging or too clean electricity.

For example, the lithium battery, which can be charged at any time with the evolution of a mobile charging bank, should meet the charging needs of ordinary customers. And this mobile phone charger is versatile! It has a mobile interface! There are a series of methods such as ordinary charging, fast charging and high current charging.

3. The 18650 is now mostly used in notebook batteries, and some flashlights are also using it. Of course, the 18650 has excellent performance, so as long as the capacity and voltage are appropriate, it is much better than batteries made of other materials, and it is also a kind of lithium battery with higher cost performance.

4. Flashlight, MP3, walkie talkie, mobile phone. It can be used as long as the voltage is 3.5-5V

Different from No. 5 battery, 18650 means that the diameter is 18 mm and the length is 65 mm, while the model of No. 5 battery is 14500, the diameter is 14 mm and the length is 50 mm

5. Generally, 18650 batteries are used more in industry, and they are also gradually introduced into civil families. In the future, they will even be developed and distributed to gas cans, rice cookers, induction cookers, etc. for backup power supply. They are often used in notebook batteries and high-end flashlights

6. 18650 is only the size and model of the battery. According to the type of battery, it can also be divided into 18650 for lithium ion, 18650 for lithium iron phosphate, 18650 for nickel hydride (rare). At present, the common 18650 is lithium ion, which is widely used in many industries.
