Correct wrong charging methods such as computers and mobile phones-lithium battery charging methods

Many consumers often share the same concept of battery usage during battery use. Currently, lithium battery is the mainstream. However, in the past, Ni-MH battery is still applied to lithium battery, in fact, lithium batteries and Ni-MH batteries use different methods in addition to different products.
Nickel-cadmium and nickel-MH battery (nico, NIMH) must be empty (fully discharged) for transportation and storage. The new power must be charged before use. New lithium-ion new batteries are powered: lithium-ion batteries require transport and storage in a semi-charged or above State. If the voltage is too low, the battery may affect its activity, or even cause the protection circuit to close the output, leading to uncharging. If the received lithium-ion battery has low power or even no power, it indicates that the battery is stored for a long time or the self-discharge is too large. The power of the new battery is charged at a high rate in the factory, causing severe polarization and poor power performance. Therefore, the battery head of the lithium-ion battery should be automatically shut down on the mobile phone three times (do not force the power on repeatedly after shutdown, it may cause cell phone or battery protection, and the output cannot be charged. Version 02/03 PPC must be backed up to avoid hard start data loss ). Then, use the mobile phone to connect to the original configuration direct charge or the original smart seat charge (do not use a non-original ordinary seat charge), and keep charging for about 1-2 hours after filling. Objective: To eliminate polarization caused by high current and fast charge of new power in the plant and to deactivate the new power due to long storage time by means of deep release and deep charge, battery metering and calibration of the battery (PPC, SP, Moto, and SE) with a power meter and code. The so-called 10-16 hours method is the old ni-MH/Ni-Cd battery (the charging time of Ni-MH battery is different from that of charger current, and the time is different) method, is not suitable

Lithium-ion battery.
Ordinary use: Generally, lithium battery can be charged, used, and stopped at any time. The cycle life refers to the number of full-charge and full-release times. Some charge/discharge operations can be considered as one of several minutes of life. The key to battery usage: Battery is full, and can be charged for 20 minutes to 30 minutes to reach saturation, but it must be avoided for a long time. After a long period of time, the charge will lead to side reactions. As a result, the capacity decreases and the internal resistance increases, resulting in capacity reduction and shutdown upon a call. PPC and other machines with a power chip, it is best to always use the power-less recharging, mainly to consider the problem of power display measurement. The battery protection circuit is designed to protect battery safety. It does not work for overcharging caused by slight overvoltage, overcurrent, and long-time charging that do not reach the dangerous limit. The charging control is completely provided by the charging device. Therefore, do not use the performance and quality of ordinary universal charge,
The USB port of the computer is charged. Charging after battery is full will seriously harm the lithium battery. After the battery is full, the battery continues to charge. The battery has a side reaction, reducing active substances, increasing junk substances, decreasing the capacity, and increasing the internal resistance. Serious overfilling directly destroys the battery structure, leading to decommission of the battery. Some chargers also provide charging protection mode, which can effectively protect the battery according to whether the battery is fully charged. lithium-ion battery can be charged at any time, with limited impact on life. For PPC and other battery with a power meter, it is recommended to use the battery after automatic shutdown to avoid affecting the electric measurement accuracy.
