Misunderstanding of Li-ion battery discharge and correct charging and discharging method

Misunderstanding of Li-ion Battery Discharge The more the lithium-ion battery is discharged, 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. First of all, too high and too low power states have the most adverse impact on the life of lithium-ion batteries, while the number of charge and discharge cycles is of secondary importance. In fact, the number of rechargeable cycles marked on most of the electrical appliances or batteries sold is based on 80% discharge as a benchmark test. Experiments have shown that for some laptop lithium-ion 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 One part; 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-ion batteries. The environment below freezing point may cause the lithium-ion battery to burn out when the electronic product is turned on, and the overheated environment will reduce the battery capacity. Therefore, if the notebook 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-ion battery mobile phones or chargers will automatically stop charging after the battery is fully charged, and there is no such thing as a trickle charge that lasts for more than 10 hours as a nickel battery charger. All lithium-ion batteries used are equipped with a protective plate for lithium-ion batteries. This protective plate is mainly used to prevent overcharge and over-discharge from harming lithium-ion batteries. Therefore, after the lithium-ion 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. Correct charging and discharging method of lithium ion battery 1. Charge according to the standard time and procedure, even the first three times; 2. When the battery is too low, try to start charging as soon as possible; 3. Do not activate the lithium ion battery In a special way, the lithium-ion battery will be naturally activated during normal use. If you insist on using the circulated first three 12-hour long charge activation methods, it will actually not be effective. Therefore, all pursuits of 12-16 hours of ultra-long charging and automatic shutdown of lithium-ion batteries are wrong. If you did something wrong in the past, please correct it in time, maybe it's not too late. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
