How to use and charge lithium-ion batteries correctly?

In the use of lithium-ion batteries, it should be noted that the battery will enter a sleep state after being placed for a period of time. At this time, the capacity is lower than the normal value, and the use time is also shortened. But lithium-ion batteries are easy to activate, as long as 3-5 normal charge and discharge cycles can activate the battery and restore normal capacity. Due to the characteristics of the lithium-ion battery itself, it is determined that it has almost no memory effect. Regarding the activation of lithium-ion batteries, many claims are: the charging time must be more than 12 hours, repeated three times in order to activate the battery. This statement that the first three charges should be charged for more than 12 hours is obviously a continuation of the statement that nickel batteries (such as nickel-cadmium and nickel-metal hydride). So this statement can be said to be misinformation at the beginning. The charging and discharging characteristics of lithium-ion batteries and nickel batteries are very different, and I can tell you very clearly that all the serious formal technical materials I have consulted emphasize that overcharge and overdischarge will affect lithium-ion batteries, especially Liquid lithium-ion batteries cause huge damage. Therefore, it is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours. Usually, the charging method analyzed in the mobile phone manual is the standard charging method suitable for the mobile phone. In addition, lithium-ion battery mobile phones or chargers will automatically stop charging after the battery is fully charged, and there is no such thing as a trickle charge that lasts for more than 10 hours as a nickel battery charger. In other words, if your lithium-ion battery is fully charged, it is also white charged on the charger. And none of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and the quality will be foolproof, so your battery will be on the verge of danger for a long time. This is another reason why we oppose long charging. In addition, on some mobile phones, after charging for a certain period of time, if the charger is not removed, the system will not only stop charging at this time, but also start a discharge-charge cycle. Perhaps the manufacturer of this approach has its own purpose, but it is clearly detrimental to the life of the battery and mobile phone/charger. At the same time, long-term charging takes a long time, often at night. According to the situation of my country's power grid, the voltage at night in many places is relatively high and fluctuates greatly. As mentioned earlier, lithium-ion batteries are very delicate, and their ability to withstand fluctuations in charging and discharging is much worse than that of nickel batteries, so this brings additional dangers. In the use of lithium-ion batteries, it should be noted that the battery will enter a dormant state after being placed for a period of time. At this time, the capacity is lower than the normal value, and the use time is also shortened. But lithium-ion batteries are easy to activate, as long as 35 normal charge and discharge cycles can activate the battery and restore normal capacity. Due to the characteristics of the lithium-ion battery itself, it is determined that it has almost no memory effect. Therefore, users do not need special methods and equipment during the activation process of new lithium-ion batteries. Not only is this true in theory, but from my own practice, it is best to use the standard method to recharge this natural activation method from the beginning. Regarding the activation of lithium-ion batteries, many claims are: the charging time must be more than 12 hours, repeated three times in order to activate the battery. The statement that the first three charges should be charged for more than 12 hours is obviously a continuation of the statement that nickel batteries (such as nickel-cadmium and nickel-metal hydride).

Therefore, it is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours. In addition, the lithium-ion battery or the charger will automatically stop charging after the battery is fully charged, and there is no so-called trickle charge that lasts for more than 10 hours in the nickel charger. In other words, if your lithium-ion battery is fully charged, it is also white charged on the charger. And none of us can guarantee that the characteristics of the battery's charging and discharging protection circuit will never change and the quality will be foolproof, so your battery will be on the verge of danger for a long time.
