Precautions for discharging lithium-ion batteries and charging mobile phone batteries

1. The discharge depth of the lithium ion battery is 80%, which means that it is discharged to the remaining 20% u200bu200bof the capacity. The effect of the depth of discharge on the battery is: the deeper the depth of discharge, the simpler the life of the lithium-ion battery will be shortened; the other aspect is the performance on the discharge curve. The deeper the discharge, the more unstable the voltage and current. Under the same discharge system, the smaller the voltage value, the deeper the discharge depth. Small current discharge is more complete. The smaller the current and the longer the working time, the less charged electricity will reach the same voltage. In short, any topic commenting on the discharge of lithium-ion batteries must consider the discharge system, the key is current. 2. When a lithium-ion battery supplies a constant amount of current to any electrical appliance, the internal resistance of the battery will increase with the decrease in capacity. Then when the depth of discharge is large, the resistance increases and the current is constant, and the battery is required to supply more power. The heat is wasted in the form of heat. 3. The relatively stable discharge curve of lithium-ion batteries will change sharply when the depth of discharge is large. Therefore, limiting the depth of discharge to a relatively flat range can enable customers to have a better control of the power and also get Better use experience. Attention should be paid to the discharging process of lithium-ion batteries. In fact, the discharging of lithium-ion batteries is to figure out the factors that affect the discharge of lithium-ion batteries. It is important to perform related operations at the time of discharge, which is also conducive to longer-lasting use of the battery. . The deeper the discharge depth of the lithium ion battery, the greater the loss of the battery; the more fully charged the lithium ion battery, the greater the loss of the battery. Lithium-ion batteries are best in an intermediate state of power, in which case the battery life is the longest. Precautions for charging the mobile phone battery ①The battery is activated and pre-charged by the manufacturer before leaving the factory, so the battery has residual power. The first 3-5 charging is generally called the adjustment period, and it should be charged for more than 14 hours to ensure that the lithium is fully activated. The activity of ions. Lithium-ion batteries have no memory effect, but are very inert. They should be fully activated to ensure the best performance in future use. ②For the first time charging, we'd better choose to turn off the charging, because it is safer to turn off the charging, and it can also extend the life of the mobile phone battery. We must pay special attention to this, because the power will continue to consume power when turned on. ③The first time we charge, we must continue to charge after fully charged, because the first charge to continue charging after the full charge can completely activate the mobile phone battery, use the original direct charge to fully charge the mobile phone when it is turned on, and then charge it for an additional hour. , This is recommended considering the error of charging control, it is not necessary to charge for 12 hours. ④When the mobile phone is charged for the first time, it should be noted that the power supply should not be unplugged during the charging process. That will cause great damage to the battery, and it can be said that it will shorten the battery life a lot. When our mobile phone battery is used for about 20%, it is about to start charging, but the mobile phone still has 80% power at night, so try not to charge it at night. Charging at night will cause some damage to your mobile phone. You can follow the above precautions to maintain the battery. The correct method of charging the mobile phone is no problem with the mobile phone battery for three years.
