What are the general misunderstandings 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 life is the longest. First of all, too high and too low power states have the most adverse impact on the life of lithium batteries, and the number of charge and discharge cycles is of secondary importance. In fact, the number of rechargeable recharges marked on most of the electrical appliances or batteries sold 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 resistance of the battery to the movement of electrons become greater and greater, thus causing the battery capacity to become smaller. Second, 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 battery capacity. 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 laptop 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. There is no such thing as a trickle charge that lasts for more than 10 hours as a nickel charger. 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 protection board will be used, and how you charge it with the charger, the battery will no longer be charged.
