What are the correct charging methods for 18650 lithium batteries and polymer lithium batteries?

Correct charging method for 18650 lithium battery 18650 lithium battery is cylindrical with liquid inside. Because of battery design and material reasons, 18650 is suitable for high current, so almost all notebooks and electric vehicles are designed with 18650 batteries; only super notebooks are energy-saving. , So you can use polymer lithium batteries instead of 18650 batteries, especially tablet computers; digital cameras can only use 18650 similar batteries because of the large voltage and instantaneous current required for charging and discharging of flashes, but they are slightly smaller in size. . 1. When using 18650 lithium battery, it should be noted that after the battery is left for a period of time, it will enter the dormant state. At this time, the capacity is lower than the normal value, and the use time is also shortened. But the lithium battery is easy to activate, as long as 35 normal charge and discharge cycles can activate the battery and restore normal capacity. 2. Due to the characteristics of the 18650 lithium battery, it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone needs no special methods and equipment during the activation process. 3. It is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours. Generally, the charging method analyzed in the instruction manual is the standard charging method. The correct charging method of polymer lithium battery The polymer battery is a new type of lithium battery. Its most notable feature is that it is very thin, light in weight, and diversified in appearance and shape, and most polymer batteries can also be used. The aluminum-plastic film is used as the shell to ensure safety during use. However, due to improper operation during use, the temperature will rise or be oxidized, and the battery will also experience gas expansion, etc., even in severe cases. Will cause an explosion. 1. To prevent excessive discharge, try not to use the mobile phone below 20% of the battery power, especially do not use the mobile phone below 5% of the battery power, which will cause irreversible damage to the polymer lithium battery. 2. Prevent use at high or very low temperatures. Charging at high and low temperatures will cause great damage to the polymer lithium battery. High temperature may cause the battery to explode, and low temperature will also have a great impact on battery life.
