When the charge is less than 20%, it can be charged, and when the charge is full, do not continue to charge. Now the lithium battery can be used with the charge, the lithium battery is the number of fully charged, that is, no matter how many times you charge.
In the use of lithium batteries, it should be noted that after the battery is placed for a period of time, it enters a dormant state, at this time the capacity is lower than normal, and the use time is also shortened. However, lithium batteries are easy to activate, as long as 3-5 normal charge and discharge cycles can be activated to restore normal capacity. Due to the characteristics of the lithium battery itself, 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.
Lithium battery phones or chargers will automatically stop charging after the battery is full, and there is no so-called \"trickle\" charging of nickel electric chargers that lasts for more than 10 hours. That is to say, if your lithium battery is full, it is also empty on the charger.
