What is the correct use and maintenance method of lithium batteries

In fact, the battery does not have too much attention to use, in other words, it is not very useful to take into account. How many times a battery can be used, the difference is more due to individual differences in the manufacture of the battery itself, rather than the method of use. In addition to its own battery quality, the battery's own service life is limited. Once the battery is off the processing line, its life will begin to elapse. Regardless of whether you use it or not, the service life of lithium batteries is only two to three years. One of the important reasons for the decrease in battery capacity is the increase in internal resistance caused by oxidation. Finally, the resistance of the electrolytic cell will reach a certain point. Although the battery is fully charged at this time, the battery cannot release the stored power. Many friends think that the lithium battery should be charged for more than 16 hours for the first use, so that the battery can be fully activated. In fact, there is no basis for doing so. This is just the popular method of charging nickel-metal hydride or nickel-cadmium batteries. Not applicable. Because this kind of lithium polymer-based battery does not theoretically have a memory effect, even if it does, it is completely negligible. So just charge it for about 3 hours. If it shows that the charging has been completed and the external power supply is not used for the time being, then you can unplug the power supply without waiting such a long time. In fact, battery maintenance has always been a hot topic for notebook computer users, and in the battery section of major notebook forums, this topic has already formed a consensus. But in fact, there are many misunderstandings. In the final analysis, it comes from two aspects. One is that the thinking has not kept up with the transition from nickel-metal hydride batteries to lithium batteries. The other is more funny and comes from mobile phones, because mobile phones are actually the first contact for most users. The arrived devices use rechargeable batteries, so some of the habits of mobile phones will be extended to the PSP for granted. I don't have the ability to train most PSP users to become experts, and there is no need for that. There is no absolute truth in the world. I will not vowed to say that my theory is correct like some friends who are only theoretically supreme, and I want everyone to be convinced by him. I just will be in the major notebook forums and the electrical industry. The opinions generally agreed by senior engineers will be shared with you. After all, PSP is a consumable, no matter how hard you work, the battery life is only 2 to 3 years. If you feel that in order to bring the so-called maintenance method to the PSP battery which is negligible to almost ineffective, you are willing to make up the full charge and discharge time and often interrupt the game and wait for the charge, then you don't need to continue reading. Below I will clarify some of the most easy to fall into the misunderstanding, and give out the views and practices that I think are correct. Misunderstanding 1: The PSP must be repeatedly charged and discharged three times to activate the battery. Unless the PSP you bought is a product that has been in stock for more than one year, don’t do this, because the current battery cell has been activated when it leaves the factory, and the cell is once again activated when it is packaged into a PSP battery. Therefore, the battery you get is already activated, and doing three more charging and discharging processes is just unnecessary loss of the new battery. Misunderstanding 2: The first charge must be sufficient for 12 hours. This is applicable to the early nickel-metal hydride battery equipment without battery control circuit, but it is a joke for the PSP with intelligent charging and discharging control module. When the PSP battery is fully charged, the charging current will be automatically cut off, and the The system is shown as an external power source. Even if you continue to charge for 120 hours, there will be no change in the state. Generally speaking, it is fully charged in 3 hours, and the remaining charge is just a waste of your own time. Instead, when you get a new machine, you should discharge the battery before charging. Misunderstanding 3: The battery should be fully charged and discharged once a month. Regarding the nickel-metal hydride battery with strong memory effect, this is necessary work, but regarding lithium battery, this cycle is too frequent. Lithium battery theoretically eliminates the memory effect, even if it has, it has been greatly weakened and can be ignored. If you use the battery frequently, then you should discharge the battery to a relatively low level (about 10~15%) and then recharge it, but if it is discharged to the point where even the machine can’t be turned on (0~1%), it belongs to the lithium battery For deep discharge with greater damage, it is generally sufficient to do this operation once every 2 months.
