Explanation of precautions for safe use of lithium batteries

Precautions for the use of lithium batteries Precautions for use: When using lithium batteries, it should be noted that the battery will enter a sleep state after a period of time. When the capacity is lower than the normal value, the use time will be shortened. However, lithium batteries are easily activated. After normal charging and discharging 3-5 times, the battery can be activated and return to normal capacity. Due to the nature of lithium batteries, they have little effect on memory. Therefore, the new lithium battery does not require special methods or equipment to activate the user's mobile phone. Not only in theory, but also in my own practice, it is best to use the standard charging method from the beginning. There are many sayings about activating lithium batteries: the charging time must exceed 12 hours, and it must be repeated three times to activate the battery. The sentence that the first three charging takes more than 12 hours is obviously a continuation of nickel-cadmium batteries and nickel-hydrogen batteries. So it was misunderstood from the beginning. The charge and discharge characteristics of lithium batteries are very different from nickel batteries, it can be very clear to you, all of my serious official technical information emphasizes that overcharging and overcharging can do a lot for lithium batteries, especially liquid lithium batteries. Therefore, it is best to charge according to the standard time and method, especially the charging time cannot exceed 12 hours. Generally speaking, the charging method described in the mobile phone manual is a standard charging method suitable for mobile phones. In addition, the mobile phone or lithium battery charger will automatically stop charging after the battery is fully charged. There is no such thing as a trickle nickel battery charger that lasts more than 10 hours. In other words, if your lithium battery is fully charged, the charger is also white. And there is no guarantee that the battery's charge and discharge protection circuit will never be destroyed, so your battery may be in danger for a long time. This is another reason why we oppose long-term charging. Regarding some mobile phones, if the charger is not unplugged after charging for a period of time, the system will not only stop charging, but also start discharging. The manufacturer of this method may have its own purpose, but it is clearly not conducive to the life of the battery and mobile phone/charger. In addition, long-term charging takes a long time, usually at night. Take my country's power grid as an example. In many places, the voltage at night is very high and fluctuates greatly. As mentioned earlier, lithium batteries are very fragile. Compared with nickel batteries, its ability to withstand fluctuations in charge and discharge is much worse, which brings additional risks. In addition, another aspect that cannot be ignored is that lithium batteries are not suitable for over-discharge, which is also very bad for lithium batteries.
