When using lithium batteries, it should be noted that the battery will enter a dormant state after being placed for a period of time. At this time, the capacity is lower than the normal value, and the use time is also shortened. However, lithium batteries are easy to activate, as long as 3-5 normal charge-discharge cycles can be used to activate the battery and restore its normal capacity. Due to the characteristics of the lithium battery itself, it has almost no memory effect.

For the "activation" of lithium batteries, there are many sayings: the charging time must be more than 12 hours, and it must be repeated three times in order to activate the battery. This statement that "the first three charges should be charged for more than 12 hours" is obviously a continuation of the statement from nickel batteries (such as nickel-cadmium and nickel-metal hydride). Therefore, this statement can be said to be misrepresented from the beginning. The charging and discharging characteristics of lithium batteries and nickel batteries are very different, and I can tell you very clearly that all the serious formal technical documents I have reviewed emphasize that overcharge and overdischarge will affect lithium batteries, especially liquid lithium batteries. Ion batteries do huge damage. Therefore, it is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours (the charger shows that it is fully charged).
