Lithium battery cell phone can't the cause of the 'recharge' for a long time

Source: 2020 - 04 - 15 hits: have time don't give reason of lithium ion cell phones' charging ': 1. In order to make full use of the capacity of the battery, any manufacturer of overcharge discharge circuit will be set up in close to the limit, leave a small margin. Therefore, mobile phone often is in a state of battery charge and discharge limits, once the battery and charger protection problems, battery life is very poor. Sometimes it can be fatal. 2, due to the overcharge protection, charging for a long time is meaningless, life test is conducted on the charger. In particular, lithium battery charger after a full charge will automatically stop, and nickel battery charger is not the so-called 'trickle-down type for 10 hours to recharge. In other words, if lithium batteries, charging on the charger is white. Can't promise not the characteristics of the charging protection circuit, if the charging time is too long, the battery will be in danger for a long time. 3. Number of lithium battery charge related to the depth of discharge. For example, the lithium ion battery charge and discharge cycle experiment table is as follows: cycle life, 10%DOD) : > 1000 cycle life ( 100% dod) : > 200 times. As can be seen from the table, the number of charge related to the depth of discharge. Simply put, if you charge it half the electricity, you won't lose additional charge life, which is 0. X, x tend to be small. 4, the lithium battery is almost no memory effect, also need to activate is very weak, natural use is enough to activate. Special reminder: lithium battery is best not to 'charge for a long time, even during the first three time charge. The complete! At the same time also opposes the use of lithium ion cell phone to turn it off. Because these are bad for the battery. As is known to all, now almost all the mobile phone use lithium battery, because the lithium battery has the advantage that the other battery can not be replaced, it is more light than other battery, no memory effect, can be directly charging and not discharging. But we know that nothing is absolute. Although in theory can be avoided discharge, just like when we when we are hungry, we eat not very hungry, we don't have the same feeling, the former can make us feel very delicious and complete, and the latter can only fill the stomach, no food. By the same token, charging is the same, although not discharge can also be a full one, but this lithium ion is in a state of no mental work, no energy nature also cannot achieve the ideal working condition. So my personal advice is lithium battery, but also to natural after their batteries run out, such a good battery will bring you the best working condition.
