How to charge a new lithium battery?

Date of Issue:2020-07-15 Click:

In the use of lithium batteries, it should be noted that after the battery is left for a period of time, it will enter a sleep state. At this time, the capacity is lower than the normal value, and the use time is also shortened. But the lithium battery is 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 battery itself, it is determined that it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone does not require special methods and equipment during the activation process.

Regarding the "activation" problem of lithium batteries, there are many sayings: the charging time must be more than 12 hours, repeated three times in order to activate the battery. This statement of "charging for the first three times for more than 12 hours" is obviously a continuation of the statement of 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 batteries and nickel batteries are very different, and I can tell you very clearly that all the serious official technical materials I have consulted emphasize that overcharge and overdischarge will affect lithium batteries, especially liquid lithium Ion batteries cause great damage. Therefore, it is best to charge according to the standard time and standard method, especially not to charge more than 12 hours (the charger shows that it is full).

In addition, the lithium battery or the charger will automatically stop charging after the battery is fully charged, and there is no so-called "trickle" charging that lasts for more than 10 hours in the nickel battery charger. In other words, if your lithium 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, another aspect that cannot be ignored is that lithium batteries are also not suitable for overdischarge, and overdischarge is also very detrimental to lithium batteries.
