　　Do not overcharge the new battery

　　At present, the secondary batteries used in the market are mainly nickel metal hydride (Ni-MH) and lithium ion (Li-ion) two types. Lithium ion batteries have been mass-produced in the liquid lithium ion battery (LiB) and polymer lithium ion battery (LiP) two kinds. So in many cases, the Li-ion marked on the battery must be a lithium-ion battery. But it is not necessarily a liquid lithium-ion battery, it may also be a polymer lithium-ion 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 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. Not only is this true in theory, but in my own practice, the "natural activation" method of charging from the beginning is the best.

　　For the newly bought lithium-ion battery "activation" problem, many say: the charging time must be more than 12 hours, 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). So it's a misrepresentation to begin with. There is a very big difference between the charge and discharge characteristics of lithium batteries and nickel batteries, and it can be very clear to tell you that all serious formal technical information emphasizes that overcharge and overdischarge will cause great harm to lithium batteries, especially liquid lithium-ion batteries. Therefore, it is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours.
