4 Misunderstandings in the Use of Li-ion Battery for Mobile Phones

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 nickel-metal hydride batteries with a strong memory effect, this is necessary work, but regarding lithium-ion batteries, this cycle is too frequent. Lithium-ion batteries theoretically eliminate the memory effect. Even if there is, it has been greatly reduced. To a negligible degree, 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 is correct. Lithium-ion batteries have serious damage to deep discharge. Generally speaking, it is enough to do this operation once every 2 months. If you rarely use batteries, you only need to do this once every 3 months. Misunderstanding 4: Working while charging or continuing to use an external power source after charging will damage the host and battery. This is the most ridiculous argument. How many responses can be obtained from the theoretical theories of the so-called hole electrons, subcharges and other mechanisms in practice? First of all, the opinions of the battery industry academia are not uniform. There are still differences in theories, how can they be used to guide consumers in practice? The loss of the battery is divided into normal loss and harmful loss. The actual loss caused by external power supply and charging while using is completely within the normal loss range of the battery. That is to say, no matter how systematic theoretical maintenance measures are taken, the battery will be It will age, just like how amazing cosmetics and maintenance can not prevent beautiful women from becoming old women, at most it only delays it, but the real effect of the whitewashing on the surface can be explained by theory. Respect for the actual use of relevant experience is the correct and scientific view of knowledge. Some people may say that the only way to prevent the battery from aging is to not use it (so many people choose to remove the battery), but this makes the PSP portability meaningless. Secondly, even in the sealed state, the battery will be over time. Prolonged and naturally aged. Batteries are actually a semi-consumable product. As long as the batteries bring you enough convenience and happiness, I think their sacrifices are valuable.
