Analyze 18650 battery performance knowledge and application fields

1. Purpose: Because of the large capacity density of the unit, it is often used in most notebook batteries. In addition, it is also often used in strong light flashlights, portable power sources (mobile phone portable chargers), etc. 2. Scale: 18650 These numbers indicate the surface scale: 18 indicates the battery diameter is 18.0mm, and 650 indicates the battery height is 65.0mm. (Our ordinary one does not. 5 batteries [AA batteries], the scale is 14500) 3. Type: Ni-MH batteries with lithium batteries and 18650 batteries. As Ni-MH batteries are rarely used now, 18650 batteries are now said. 4. Voltage and capacity specifications: Ni-MH battery voltage is 1.2v, normal capacity is 4500MAH, lithium battery voltage is 3.6v-3.7, normal capacity is 1500MAH-2600MAH, and the current maximum capacity is 3000MAH. Compared with the currently commonly used No. 5 battery, the 18650 lithium battery has significant advantages in terms of size, volume and capacity. Such as 2400MAH18650 battery, the voltage is calculated according to the 3.7V specification, and the power is 8880MWH. The best Sanyo currently does not. 5. Rechargeable battery ENELOOP, capacity 2000MAH, voltage 1.2v, power 2400MWH can be seen, a good 18650 battery, the power capacity is nearly 4 times that of no. 5Battery. Application of 18650 lithium battery 1. Energy storage is mainly used in base station power supply, clean energy storage, grid energy storage, household optical storage system, etc. 2. Power supply mainly refers to electric vehicles, electric bicycles, new energy vehicles, etc. 3. Digital mobile phones, tablet computers, notebook computers, electric toys, MP3/MP4, earphones, charging bags, model airplanes, mobile power supplies, etc. The price of 18650 lithium battery judges that the ex-factory price of 18650 battery is 1000mAh. The ex-factory price of 1000 mAh is 3.6/4.0/6.0 yuan, and the market price is about 8 yuan and 18650 yuan. The profit is first thrown to the merchants and then to the wholesalers. A single battery is generally around 3.2, and the actual capacity is about 800mAh. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
