Precautions
Avoid using under harsh conditions, such as high temperature, high humidity, long-term exposure in summer sun, etc., to avoid putting the battery into fire.
When removing the battery, make sure that the electrical appliance is in the power off state; the operating temperature should be kept between -20~50 °C.
Avoid storing the battery for a long time in a consumer that has been discontinued. 


Instructions
1. How to charge a new battery,
In the use of lithium batteries, it should be noted that after the battery is placed for a period of time, it enters a sleep state. At this time, the capacity is lower than the normal value, and the use time is also shortened. However, the lithium battery is easy to activate, as long as the battery is activated after 3 to 5 normal charge and discharge cycles, and the normal capacity is restored. Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone does not require special methods and equipment during the activation process.
For the "activation" problem of lithium batteries, many claims are: charging time must be more than 12 hours, repeated three times in order to activate the battery. This statement that "the first three charges have to be charged for more than 12 hours" is obviously a continuation of nickel batteries (such as nickel cadmium and nickel hydride). So this kind of statement can be said to be misinformation at the beginning. The charge and discharge characteristics of lithium and nickel batteries are very different, and it is very clear to tell you that all the serious formal technical information I have reviewed emphasizes that overcharge and overdischarge will make lithium batteries, especially liquid lithium. Ion batteries cause great damage. Therefore, charging is best done according to standard time and standard methods, especially not for more than 12 hours of ultra-long charging (charger display full).
In addition, the lithium battery or charger will automatically stop charging when the battery is fully charged, and there is no so-called "turbulent" charging that the nickel battery charger has for 10 hours. In other words, if your lithium battery is full, it will be white charger on the charger. And none of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and the quality will be foolproof, so your battery will be on the edge of danger for a long time. This is another reason why we oppose long charging.
In addition, another aspect that cannot be ignored is that lithium batteries are also not suitable for over-discharge, and over-discharge is also disadvantageous for lithium batteries.
