Charge 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 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 saying that deep discharge eliminates 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 it will not be able to charge 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 temperature is suitable, and it can prevent 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 to delay the aging of the batteries. In fact, one of the parameter designs of lithium batteries is the appropriate temperature. Relatively speaking, lower temperatures are not a big problem, but if they are placed at a higher temperature, the old saying goes that the substance will be reversed, which will also cause safety problems. 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 is to be done in a normal environment? The water side is moisture-proof and the hot side is sun-proof. Therefore, the suitable environment for daily maintenance of lithium batteries should be four words: ventilation and coolness. These four words should be followed regardless of whether the lithium battery is left unused independently or used 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 avoid its final loss, but we use the correct method to delay its aging.
