Is it true that the battery must be charged for more than 12 hours in the first three charges?

The statement that the first three charging times should exceed 12 hours is largely derived from the statement that nickel batteries (such as nickel cadmium and nickel metal hydride) continue to be charged. So this statement can be said to be a preliminary misstatement. The charge and discharge characteristics of lithium batteries and nickel batteries are very different. It can be clearly told that overcharge and overdischarge can cause great damage to lithium batteries, especially liquid lithium batteries. Therefore, it is best to charge according to the standard time and standard charging method, especially not to exceed 12 hours of ultra-long charging. Many instructions on the phone say that a new battery must be charged for more than 12 hours. Lithium battery charging method. In addition, mobile phones or chargers with lithium batteries will automatically stop charging when the battery is fully charged, instead of continuously charging for 10 hours like nickel battery chargers. In other words, assuming that your lithium battery is fully charged, it is also charged in white on the charger. In addition, on some mobile phones, if the charger is not removed after charging for a period of time, the system will not only continue to charge, but also have a preliminary charge and discharge cycle. Perhaps the manufacturers of this approach have their own goals, but this is very unfortunate for the life of the battery and mobile phone/charger. Lithium battery charging method. Another aspect that cannot be ignored is that lithium batteries are not suitable for over-discharge, which is also very unfortunate for lithium batteries. Lithium battery charging method. In normal operation, when should the initial cost be paid: How to charge the lithium battery? We often see this sentence: Because the number of charging and discharging is limited, mobile phone batteries should be used up and charged as much as possible. However, this statement is obviously wrong! Under normal circumstances, you should have a storage according to the principle of recharging when the remaining battery is used up (but certainly not using shutdown and recharging), if your battery is the next day you expect Can’t last all day, you should start the initial charge in time! When you need to charge to deal with an important event that may make the communication busy, even if the battery has a lot of power, you can charge it in advance, because you have not really lost One charging cycle life! The principle of recharging the battery after it is used up is not to go to the telephone pole. No matter how common long charging is, try to use up your phone's battery. It is best to shut down automatically. This approach is actually nickel batteries in order to prevent the recall effect. Unfortunately, it is also used in lithium batteries. In the past, some people complained after their mobile phones were low on battery, and they continued to use them without charging, and they kept using the example of automatic shutdown. Therefore, the mobile phone in this example does not respond when it is charged and turned on in the future, and must be sent for repair. This is actually because the battery is over-discharged and the voltage is too low, so there is no normal charging and starting conditions. Practical and relevant experience has proved that the scrap rate of lithium batteries with a discharge depth of 100% is 50% (years of facts have proved that as long as half of the maintenance power supply for lithium batteries with a discharge depth of more than 99% is activated, the other half will be scrapped!)
