The correct method of charging and discharging lithium batteries

The correct method of charging and discharging lithium batteries can not only extend the service life of the lithium battery, but also keep the battery in a safe state. There are many types of batteries on the market, and each type of battery has its own unique personality and usage method, which is reasonable and standardized. The use of batteries is very important. Next, the author will talk about the correct charging and discharging methods of lithium batteries; the 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 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 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 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. 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, and 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 remain in the high heat discharged from 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 mobile phones or chargers will automatically stop charging after the battery is fully charged, and there is no so-called 'trickle' charging that lasts for more than 10 hours in nickel battery chargers. All the lithium batteries used have a protection board on which a lithium battery is added. 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 work, and how you charge it with the charger, the battery will no longer be charged. Correct charging and discharging method of lithium 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. The activation of the lithium battery does not require special The method, in normal use, the lithium battery will be naturally activated. If you insist on using the popular'first three 12-hour long charge activation' method, it will actually not be effective. Therefore, all pursuits of 12-16 hours of ultra-long charging and automatic shutdown of lithium batteries are wrong. If you did something wrong in the past, please correct it in time, maybe it's not too late. The correct discharge method of lithium battery is charged in time to prevent overdischarge. Ordinary lithium battery users are not aware of the hazards of over-discharge, because there are usually no reports of safety accidents in over-discharge. Moreover, some people even think that regular deep discharge is good for the maintenance of battery performance. In fact, this is not the case, because the memory effect of lithium batteries is negligible, and there is no such thing as a deep discharge to eliminate the memory effect. Theoretically, the total cycle life of a lithium battery with deep discharge will be longer, but the risk is that over-discharge of the battery will cause the battery voltage to be too low and cannot be charged normally. The two evils are the lesser one, and a shorter service life is better than no use. In the correct use of lithium batteries, the charging method of lithium batteries is the most important, because incorrect charging methods will cause safety problems, and discharge and daily maintenance affect only the service life of lithium batteries, and lithium batteries themselves are also a kind of Consumables, no matter what we take, we can't avoid its final loss, but we use the correct method to delay its aging. The above is the misunderstanding of lithium battery discharge, the correct charging and discharging method of lithium battery. Therefore, it is best to charge the lithium battery according to the standard time and standard method, especially not to charge more than 12 hours. Usually, the charging method described in the instruction manual is the standard charging method. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
