The statement about charging lithium batteries for twelve hours

- Aug 05, 2019-

Generally, the battery voltage of the mobile phone is 3.7V, but the voltage of the general charger is 5V, but it will not affect the use, because there is no 3.7V mobile phone charger sold at all.

The cylindrical lithium battery of No. 5, that is, the battery of 14,500. It is through the technology of lithium battery regulator, the voltage of the battery is adjusted to 3.0V voltage suitable for small appliances.

For the "activation" problem of newly purchased lithium-ion batteries, many claims are: charging time must be more than 12 hours, repeated three times in order to activate the battery. This statement that "the first three charges should be charged for more than 12 hours" is obviously a continuation of the nickel battery (such as nickel cadmium and nickel hydrogen). So this kind of statement can be said to be misinformation at the beginning. The charge and discharge characteristics of lithium batteries and nickel batteries are very different, and it is very clear to tell everyone that all serious formal technical information emphasizes that overcharge and overdischarge can cause huge problems for lithium batteries, especially liquid lithium ion batteries. hurt. Therefore, charging is preferably performed in accordance with standard time and standard methods, especially for ultra-long charging of more than 12 hours.
