Lithium battery charging method
In the use of lithium batteries, it should be noted that after the battery is left for a period of time, it will enter the dormant 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 the battery can be activated and restored to normal capacity after 3 to 5 normal charge and discharge cycles. Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect. Therefore, the user does not need special methods and equipment during the activation process of the new lithium battery. Not only is this true in theory, but from my own practice, it is best to use the standard method of charging from the beginning, which is the "natural activation" method.
Regarding the "activation" problem of lithium batteries, many sayings are: the charging time must be more than 12 hours, repeated three times in order to activate the battery. This statement of "the first three charges should be charged 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.
In addition, the lithium battery or 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 as a nickel 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 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. This is another reason why we oppose long charging.
