What kind of misunderstandings about the discharge of lithium batteries?

Misunderstanding of Lithium Battery Discharge The more the lithium battery is discharged, the greater the loss of the battery. Lithium batteries are best in an intermediate state of power, in which case the battery has the longest life. First of all, the state of charge that is too high and too low has the most adverse effect on the life of the lithium battery, while the number of charge and discharge cycles is of secondary importance. In fact, the number of rechargeable recharges marked on most electrical appliances or storage batteries are based on 80% discharge as a benchmark test. Experiments have shown that for some laptop lithium batteries, the battery voltage often exceeds the standard voltage by 0.1 volts, from 4.1 volts to 4.2 volts, then the battery life will be halved, and if it is increased by 0.1 volts, the life will be reduced to 3 points. One: The long-term low or no power state will make the internal resistance of the battery to the movement of electrons become greater and greater, thus causing the battery capacity to become smaller. Secondly, temperature also has a greater impact on the life of lithium batteries. The environment below freezing point may cause the lithium battery to burn out when the electronic product is turned on, while the overheated environment will reduce the capacity of the battery. Therefore, if the laptop is used for a long time without removing the battery from an external power source, the battery will be exposed to the high heat emitted by the notebook for a long time. More importantly, the battery will be in a state of 100% power for a long time and will soon be scrapped. Lithium battery cell phones or chargers will automatically stop charging after the battery is fully charged, and there is no so-called trickle charge of nickel battery chargers that lasts for more than 10 hours. All the lithium batteries used have a protection board for the lithium battery installed on it. This protection board is mainly used to prevent overcharge and overdischarge from harming the lithium battery. Therefore, after the lithium battery is fully charged, the protective board will be used. How about charging it with the charger, the battery will no longer be charged.
