What should be noted when using 3V lithium batteries is that the battery enters a dormant state after being left for a period of time. At this time, the volume is less than the specified value and the use time is also reduced. However, lithium batteries are very easy to activate and only need to be activated after 3 -Five normal discharge cycles can activate the battery and restore it to normal capacity. Due to the characteristics of the lithium battery itself, it basically has no memory function. Therefore, the 3V lithium battery in the customer's mobile phone does not need to be activated during the activation process. Special methods and equipment. Not only is this true in theory, but from my own practical experience, it is better to use a "natural activation" method such as standard charging from the beginning.

Regarding the "activation" problem of lithium batteries, many people say that the charging time must be more than 12 hours, and do it three times in a row to activate the battery. This kind of "the first three times of charging must be charged for more than 12 hours" is called This method is obviously a name inherited from nickel batteries (such as nickel cadmium and nickel metal hydride). Therefore, this kind of name can be said to have been spread randomly from the beginning. There is a very big difference in the charge and discharge characteristics of 3V lithium batteries and nickel batteries. , and I can tell you very clearly that any strict published technical documents I have reviewed note that overcharging and over-discharging will cause great damage to lithium batteries, especially liquid lithium-ion batteries. Therefore, charging should still be carried out in accordance with Standard charging time and standard method, especially long charging of more than 12 hours is not required. Generally, the charging method described in the mobile phone manual is the standard charging method suitable for the mobile phone.

In addition, lithium battery cell phones or chargers will automatically stop charging after the battery is full, and there will not be the so-called "trickle" charging of nickel battery chargers that lasts for more than 10 hours. In other words, , if your lithium battery is fully charged and placed on the charger, it will be charged in vain. And none of us can ensure that the characteristics of the battery's charging and discharging protection power circuit will never change and the quality is foolproof, so your battery will last for a long time. Time is on the verge of risk. This is another reason why we resist long charging.

In addition, for some mobile phones, after charging for a certain period of time, if the charger is not removed, the system will not only not stop charging, but also start a discharge-charge-discharge cycle. Perhaps manufacturers of this approach have already Its purpose is obviously bad for the life of the battery and mobile phone\/charger. At the same time, long-term charging requires a long time, usually at night, and judging from the situation of my country's power grid, many areas The working voltage at night is relatively high and fluctuates greatly. As mentioned before, 3V lithium batteries are very delicate, and their ability to withstand fluctuations in charge and discharge is much different than that of nickel batteries, so this creates additional risks. sex.

In addition, another aspect that cannot be ignored is that 3V lithium batteries should not be overcharged or discharged. Overcharging and discharging is also very bad for lithium batteries.
