Reasons why lithium battery mobile phones cannot be 'charged for a long time'

Reasons not to charge lithium-ion mobile phones: 1. In order to make full use of the battery capacity, any manufacturer's overcharge and overdischarge circuit will be set close to the limit, leaving a small margin. Therefore, mobile phones are often in the battery charge and discharge limit state. Once the battery and charger have protection problems, the battery life will be very poor. Sometimes it can be fatal. 2. Due to the protection of overcharging, charging for a long time is meaningless unless it is a life test on the charger. In particular, the lithium battery charger will automatically stop charging after it is fully charged, while the nickel battery charger does not have the so-called trickle charging that lasts for 10 hours. In other words, if the lithium battery is fully charged, it is also charged in white on the charger. There is no guarantee that the characteristics of the charging protection circuit will never change. If the charging time is too long, the battery will be in a dangerous state for a long time. 3. The number of charging times of lithium batteries is related to the depth of discharge. For example, the lithium battery charge and discharge cycle experiment table is as follows: Cycle life (10% DOD): >1000 Cycle life (100% DOD): >200 times. It can be seen from the table that the number of charges is related to the depth of discharge. Simply put, if you charge half the battery, you will not lose the extra charge life, which is zero. When x is multiplied, x tends to be small. 4. The memory effect of lithium battery is almost non-existent, and it is weak to activate. Natural use is enough to activate. Special note: It is best not to charge the lithium battery for a long time, even during the first three charging periods. Complete! It is also opposed to using lithium-ion mobile phones to shut down. Because these are bad for the battery. As we all know, almost all mobile phones today use lithium batteries, because lithium batteries have the irreplaceable advantages of other batteries. They are lighter than other batteries, have no memory effect, and can be charged directly without discharging. But we know that few are absolute. Although it is theoretically possible to prevent discharge, just like when we are hungry and we are not too hungry, we will not feel the same. The former will make us feel very delicious and complete, while the latter can only fill our stomachs. food. In the same way, charging is the same. Although it can be full without discharging, the lithium ion is in a state of mentally inactive work. Without energy, it will naturally not be able to achieve the most ideal working state. So my personal recommendation is lithium batteries, and they should be used up naturally after recharging. Such a good battery will bring you the best working condition.
