Do you know what the storage capacity of a typical 18650 lithium-ion battery is?

Generally speaking, a 18650-type lithium-ion battery has to be composed of volumetric size. Generally, it is felt that after the full-load working voltage of the lithium-ion battery is put below 3.0V, it will feel that the battery is exhausted (the actual value must be seen on the door of the battery protection board Limit values, for example, as low as 2.8V, there are also 3.2V). Most lithium-ion batteries cannot be charged and discharged with a full-load operating voltage below 3.2V, otherwise excessive charging and discharging will harm the battery (the lithium-ion battery on the general sales market is only applied with a lithium-ion battery protection board. Therefore, excessive charging and discharging will continue to cause the lithium-ion battery protection board to fail to test the battery, and then unable to charge the battery). 4.2V is the maximum working voltage for battery charging. Generally, I feel that the battery is fully charged when the full-load working voltage of the lithium-ion battery is charged into 4.2V. During the whole process of battery charging, the working voltage of the battery is slowly increased from 3.7V to 4.2 V. Lithium-ion battery charging cannot charge the full-load working voltage above 4.2V, otherwise it will harm the battery. This is the unique area of u200bu200blithium-ion batteries. Generally speaking, 18650 lithium-ion batteries have the following advantages. 18650 lithium ion batteries can be connected in series and parallel to form a 18650 lithium ion battery pack. And it has the advantage of small internal resistance: the internal resistance of polymer batteries is smaller than that of ordinary liquid lithium ion batteries, and the internal resistance of domestic polymer batteries can even be guaranteed below 35m, which greatly reduces the self-consumption of the battery. Increasing the battery life on the mobile phone can thoroughly achieve the level of international docking. This type of polymer lithium-ion battery suitable for large charge and discharge current is also an ideal choice for remote control models, and it has become the most anticipated product to replace Ni-MH batteries.
