18650 battery 3.7v 2000mah

　　Current mobile power products use lithium-ion batteries as energy storage units. The lithium-ion battery has two technical routes. One is the cell of a liquid lithium-ion battery. The so-called 18650 lithium-ion battery is a model with a diameter of 18mm and a height of 65mm. The other is a Li-polymer battery, usually designed as a prismatic Li-ion battery. Lithium polymer batteries can also power many devices because they can be in any shape. High safety performance 18650 lithium-ion battery has high safety performance. In order to prevent battery short circuit, the positive and negative electrodes of the 18650 lithium-ion battery are separated. Therefore, the short circuit phenomenon may have been reduced to the limit. A protective plate can be installed to prevent the battery from overcharging and over-discharging, which also prolongs the life of the battery. The capacity of the 18650 lithium-ion battery is generally between 1200mah and 3600mah, and the general battery capacity is only about 800mah. If the 18650 lithium-ion battery is combined into a 18650 lithium-ion battery pack, the 18650 lithium-ion battery pack can easily exceed 5000mah. The biggest disadvantage of the 18650 Li-ion battery is that it is a fixed size and does not fit well in some laptops or some products. Of course, this disadvantage can also be said to be an advantage. This compares to other lithium-ion batteries, such as polymer lithium-ion batteries. This is a downside in terms of being customizable and resizable. It has become an advantage over some products with specified battery specifications. In fact, when it comes to lithium-ion batteries, the reason for the explosion is understandable. After all, the stability of this kind of stability was not strong in the past, but as a lithium-ion battery with a very high performance comparison, its application is bound to become more and more extensive. After all, 18650 lithium-ion batteries are the best choice when it comes to this essential battery.
