Brief introduction of 18650 lithium ion battery performance

18650 Lithium-ion battery use: Because of its large capacity per unit density, it is often used in most notebook batteries. In addition, it is also commonly used in high-end glare flashlights, portable power supplies (mobile chargers), and so on. 18650 lithium-ion battery size: 18650 these numbers represent the external size: 18 refers to the battery diameter 18.0mm 650 refers to the battery height 65.0mm, our ordinary 5th battery [AA battery], the size is 14500. 18650 lithium-ion battery type: 18650 There are lithium-ion batteries and nickel-metal hydride batteries. Since nickel-metal hydride is now used very little, we are now talking about 18650 batteries. Without special instructions, they are batches of 18650 lithium-ion batteries. 18650 lithium-ion battery voltage and capacity specifications: nickel-hydrogen battery voltage is 1.2V, common capacity is 4500MAH, lithium ion battery voltage is 3.6V-3.7, common capacity is 1500MAH-2600MAH, and the current maximum capacity is 3000MAH. The 18650 lithium ion battery has great advantages over the commonly used AA battery in terms of weight, volume, and capacity. For example, a 2400MAH 18650 battery, the voltage is calculated according to the standard 3.7V, and the power is 8880MWH. The best Sanyo No. 5 rechargeable battery, ENELOOP, has a capacity of 2000MAH, a voltage of 1.2V, and a power of 2400MWH. It can be seen that a good 18650 battery has a power capacity close to 4 times that of the No. 5 battery. 18650 lithium-ion batteries are now imported and domestically produced.
