18650 battery performance parameter analysis

1. Uses: Because of the large capacity per unit density, it is often used in most laptop batteries. In addition, it is also often used in high-end bright flashlights, portable power supplies (mobile chargers), and so on. 2. Size: The numbers 18650 represent the appearance size: 18 refers to the battery diameter of 18.0mm 650 refers to the battery height of 65.0mm. 3. Variety: 18650 lithium batteries include lithium batteries and nickel-metal hydride batteries. Because nickel-metal hydride is rarely used today, we are talking about 18650 batteries. What is not specifically stated is 18650 lithium batteries. 4. Voltage and capacity specifications: Ni-MH battery voltage is 1.2V, common capacity is 4500MAH, lithium battery voltage is 3.6V-3.7, common capacity is 1500MAH-2600MAH, and the current maximum capacity is 3000MAH. 5. Voltage: The core of the 18650 lithium battery voltage is the operating voltage, also called the nominal voltage, which is 3.7V, which is equivalent to three nickel-cadmium or nickel-metal hydride batteries connected in series. There are also some domestic lithium battery processing manufacturers planning the operating voltage as 3.6V. 6. 18650 lithium battery capacity: 18650 lithium battery capacity is scattered between 1000mAh and 3000mAh, but the more mature technology is generally between 1800mAh and 2600mAh. If the capacity of 18650 lithium battery is too high, the cost will increase greatly, and the significance of 18650 lithium battery with too high capacity in non-special category is not great. 7. Temperature range: 0+60, charging temperature: 0+45, operating temperature: -20-50, the best operating temperature is 20-40, 60 degrees Celsius is the temperature to ensure battery life, high temperature will reduce life, higher than 100 degrees Celsius There will be risks, generally 140 degrees Celsius will burn or blast.
