Full automatic power off. When the battery voltage rises to 4.2V, stop charging.
Lithium battery service life is relatively long, the service life can reach more than six years, with high power bearing capacity, easy to start high strength acceleration, low self-discharge rate without memory effect. Lithium batteries have a high energy density compared to batteries. With a high storage energy density, it has reached 460-600Wh\/kg, which is about 6-7 times that of lead-acid batteries.
Compared with lead-acid batteries, lithium batteries are light in weight, and the weight is about 1\/5-6 of lead-acid products under the same volume. Lithium batteries have strong adaptability to high and low temperatures, can be used in the environment of -20 ° C --60 ° C, and can be used in the environment of -45 ° C after process treatment.
Will automatically power off, do not full the battery, in fact, no matter how much or less of your remaining power, charging the phone to 100% will cause some damage to the phone battery. The optimal charging state is 65%-75%. Although the lithium battery configured by the mobile phone will automatically power off after it is full, excessive charging will not only damage the battery, but also lead to a series of safety accidents due to mobile phone or data cable problems.
Lithium full charge will automatically power off?
And this one? The lithium battery itself does not have this function, but we have this automatic power off function inside the charger.
