How to charge a new battery When using a lithium-ion battery, 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 service time will also be shortened. However, lithium-ion batteries can be easily activated. After 35 normal charging and discharging cycles, the batteries can be activated to restore their normal capacity. Lithium ion battery has almost no memory effect due to its own characteristics. Therefore, users should not use special methods and devices during the activation of new lithium ion batteries. Not only in theory, but also in my own practice, it is the best to use the standard method of charging from the very beginning. As for the activation of lithium-ion batteries, many people have said that the charging time must exceed 12 hours. Repeat it three times to activate the batteries. The statement that the first three charges will take more than 12 hours is obviously a continuation of the statement from nickel batteries (such as nickel cadmium and nickel hydrogen). 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 we can tell you very clearly that all the serious formal technical data I have reviewed emphasize that overcharge and overdischarge will cause great damage to lithium ion batteries, especially liquid lithium ion batteries. Therefore, it is better to charge according to the standard time and method, especially not to charge for more than 12 hours. In addition, the lithium ion battery or charger will automatically stop charging after the battery is fully charged. There is no so-called trickle charging that lasts for more than 10 hours in the nickel charger. That is to say, if your lithium ion battery is fully charged, it will also be charged in white on the charger. And none of us can guarantee that the characteristics of the battery charging and discharging protection circuit will never change and the quality will be foolproof, so your battery will be at the edge of danger for a long time.

This is another reason why we oppose long charging. In addition, for some machines, if the charger is not removed after charging for a certain time, the system will not only not stop charging, but also start the discharge charging cycle. Perhaps the manufacturers of this practice have their own purposes, but it is obviously detrimental to the battery life. At the same time, long charging takes a long time, usually at night. In the case of China's power grid, the voltage at night in many places is relatively high and fluctuates greatly. As has been said before, lithium-ion batteries are very delicate. They are much less able to withstand fluctuations in charge and discharge than nickel batteries, which brings additional risks. In addition, another aspect that cannot be ignored is that lithium ion batteries are also not suitable for overdischarge, which is also very unfavorable for lithium ion batteries.
