1, use: Because the capacity of the unit density is very large, it is often used for most of the notebook batteries. In addition, it is often used for high-end strong light flashlight, portable power supply (mobile phone charger) and so on.


Size: 18650 These numbers represent the appearance size: 18 refers to the diameter of the battery 18.0 mm 650 refers to the height of the battery 65.0 mm. (Our average battery number 5[AA], size 14500)


3, type: 18650 batteries have lithium-ion batteries and nickel-metal hydride batteries. Since nickel-metal hydrogen is now used very little, now say 18650 batteries, not specified, are batch 18650 lithium-ion batteries.


4, voltage and capacity specifications: nickel-metal hydride battery voltage 1.2 V common capacity 4500 MAH lithium ion battery voltage of 3.6 V-3.7 common capacity of 1500 MAH-2600 MAH, now the maximum capacity of 3000 MAH. The 18650 lithium-ion battery has a great advantage over the commonly used No. 5 battery in terms of weight, volume, and capacity. For example, a 2400MAH 18650 battery, the voltage is calculated according to standard 3.7 V and the power is 8880MWH. The best Sanyo No. 5 charging battery ENELOOP now has a capacity of 2000MAH, a voltage of 1.2 V, and a power of 2400MWH. As can be seen, a good 18650 battery has a power capacity close to 4 times that of the No. 5 battery.
