Recharging Method of Lithium-ion battery to Correct Errors in Computer and Mobile Phone

Many consumers often use the same concept when using the battery. Now lithium batteries are the mainstream, but the use of nickel-hydrogen batteries is still applied to lithium batteries. In fact, lithium batteries and nickel-metal hydride The battery is not the same except for the product.

Nickel-cadmium and nickel-metal hydride batteries (NICO, NIMH) must be transported and stored in air (full discharge). The new power must be charged before it can be used. The new lithium-ion battery is powered: Lithium-ion batteries require half-charged state to transport and store. If the voltage is too low, it will affect its activity and even cause the protection circuit to turn off and output. If the received lithium-ion battery is low or even low, it means that the battery is stored for a long time or the self-discharge is too large. The power of the new battery is charged in the factory with high-rate current, the polarization is serious, and the power effect is not good. Therefore, the first three times of the lithium-ion battery should be used in the mobile phone to shut down naturally (do not repeatedly boot after the shutdown, it may cause the phone or battery Protection, cut off the output can not be charged. The 02/03 version of the PPC must back up the system to avoid hard data loss). Then use the mobile phone to connect to the original direct charge or the original smart charger (it is recommended not to use the ordinary charger), and keep charging for about 1-2 hours after filling. Purpose: To deepen the deep charge, eliminate the polarization caused by the new high current fast charge in the factory, and the passivation caused by the long storage time. At the same time, the battery with the fuel gauge and chip (PPC, SP, moto and SE) Perform a fuel gauge calibration. The so-called 10-16 hour method is the method of the old nickel-hydrogen/nickel-cadmium battery (the charging time of the nickel-hydrogen battery is different from the charger current and the time is different), which is completely unsuitable.

Lithium-ion battery.

Usually used: general lithium battery can be charged, used, and stopped. Cycle life refers to the number of full charge and full discharge, and partial charge and discharge can be understood as a fraction of the life. The key to battery use: the battery is full, you can charge for 20 minutes - half an hour to achieve saturation, but be sure to avoid charging after a long time. Continued charging for a long time after full will cause side reactions, resulting in a decrease in capacity and an increase in internal resistance, resulting in a shortened capacity and a shutdown when a call is made. Machines with power-carrying chips such as PPC are best used until they are recharged, mainly considering the problem of metering. The protection circuit inside the battery is designed to protect the safety of the battery. It does not work at all times caused by slight overvoltage, overcurrent, and long-term charging that do not reach the dangerous limit. Charging control is provided entirely by the charging device. Therefore, do not use the ordinary universal charger with good effect and poor quality, and the computer USB port to charge. Continue charging after the battery is fully charged is very harmful to the lithium battery. After the battery is fully charged, the battery will generate side reactions, the active material will decrease, the amount of garbage will increase, the capacity will decrease, and the internal resistance will increase. The serious overcharge will directly damage the battery structure and cause the battery to be scrapped. Now some chargers also provide a charging protection mode, which can effectively protect the battery according to whether the battery is fully charged or not. Lithium-ion batteries can be charged at any time, and the impact on life is limited. For batteries with PPC, it is recommended. Use automatic shutdown to charge, so as not to affect the accuracy of fuel gauge.
