How to properly discharge and maintain lithium batteries?

The correct discharge method of lithium battery is charged in time to prevent over-discharge. Ordinary mobile phone users are not aware of the hazards of over-discharge, because there are usually no reports of safety incidents in over-discharge. Moreover, some people even think that regular deep discharge is good for maintaining 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 speaking, 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, sometimes it will take a long time to turn on, or even fail to turn on. The two evils are the lesser one. A shorter service life is better than no use. Therefore, users of mobile phones and laptops are advised not to frequently use black screens. The lithium battery is properly maintained at a suitable temperature and protected from heat and cold. When idle, lithium batteries usually do not have safety accidents. The purpose of daily maintenance is to place the lithium batteries in a suitable environment, thereby delaying the aging of the batteries. In fact, one of the parameter designs of lithium batteries is the appropriate temperature. Relatively speaking, lower temperature is not a big problem, but if it is placed at a higher temperature, as the saying goes, the thing is extremely reversed, and safety problems will also occur. The idle state we are talking about is only in terms of the normal environment. If the lithium battery is placed in water or close to the fire source, it will be out of the topic of maintenance. Then, what should be done in a normal environment? The water side is moisture-proof and the hot side is sun-proof. Therefore, the appropriate environment for daily maintenance of lithium batteries should be four words: ventilation and cool. These four words should be followed regardless of whether the lithium battery is left unused independently or ready for use in electrical appliances. 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 prevent its final loss, but we use the correct method to delay its aging.
