Four misunderstandings of lithium-ion battery maintenance

The maintenance of lithium-ion batteries is very important. There are four misunderstandings in the maintenance of lithium-ion batteries. You must understand the legend: PSP must be charged and discharged three times to activate the battery. Unless you have purchased PSP stock products for more than one year, there is no need to do this, because the current battery battery factory has been activated. When the battery is packaged into a PSP, the battery is equivalent to being activated and tested again, and the battery is obtained. It has been activated and only three charges And the unnecessary loss of the new battery during the discharge process. Misunderstanding 2: The first charge must last for 12 hours. Early devices using Ni-MH batteries did not have a battery control circuit. This is true, but for today's psp with an intelligent charge and discharge control module, this is a joke. When the PSP battery is fully charged, the charging current will be automatically cut off and displayed on the system as an external power source. Even if you continue to charge for 120 hours, it will not change the state. Generally speaking, if you charge the battery once every 3 hours, the remaining time is a waste of time. On the contrary, when you get a new machine, you should let it go before charging it. Myth 3: The battery needs to be charged once a month. The memory effect of NiMH batteries is very strong, which must work, but for lithium-ion batteries, the cycle is too frequent.Lithium-ion batteries, in theory, eliminate the memory effect. Even if there is, it will greatly weaken the insignificant degree. The battery used is very frequent, so you should discharge the battery low (about 10~15%), but if the discharge or even turn on the machine (0~1%), the depth of discharge of the lithium ion battery is very harmful, usually every two Do this operation once a month. If you rarely use the battery, use it every three months. Misunderstanding 4: Working while charging or continuing to use external power after charging will damage the host and battery. This is the most absurd argument. How many reactions can be obtained from the hole-electron theory and the secondary charge mechanism? The battery industry academia is not unified on this point of view. There are still differences in theory, how to guide consumers to use it in practice? Battery consumption is divided into normal loss and damage loss, the degree of power converter use and cost loss. The real reason for use is completely normal wear and tear. That is to say, no matter how much Theoretical maintenance measures system, battery aging, just like how magical cosmetics and maintenance can not prevent beautiful women from turning into old women, most of them are slow, but on the surface how many real plasters can be explained by practical procedures, this is by no means the theory can explain The actual use of relevant experience is the correct respect and understanding of scientific concepts. It can be said that the only way to prevent the battery from aging is to not use it (many people choose to remove the battery), but this will make the portability of the PSP meaningless, and even if the battery is stored, it will naturally over time Ageing. The battery is actually half-consuming, as long as it can bring you enough convenience and fun, I think its sacrifice is worthwhile. Therefore, the generally accepted battery maintenance and use methods are as follows: 1. Avoid complete discharge (black screen power failure) 2. Frequent charge and discharge of lithium-ion batteries, charge when not used up, use external power, use while charging, and continue to use after charging External connection will not cause additional loss to the battery. 2. When not in use for a long time, please take out the lithium ion battery and store it in a cool and dry place. Do not freeze to avoid water vapor erosion. Prevent use in a hot car. If the storage time is long, charge the battery to 40%, and then place it 3. As a laptop user, if you use a fixed power supply most of the time, you can take the battery out and put it in a cool place, but this is just to increase the temperature of the battery , Humidity and other environmental factors. As for the PSP, using an external power supply with a battery will not cause additional damage to the battery. In order to carry and protect the battery cover, the metal contact principle is not recommended to use an external power source, and often remove the battery. 4. Prevent the purchase of spare lithium-ion batteries for storage, because even if the battery is not used, its service life is naturally damaged, so the battery life is limited, the best battery to use reflects the value of the battery, don't torture yourself and all kinds of non-cutting The actual theory and used to entertain the PSP.
