This question is closely above the activation of the batteries, to mention a laptop battery factory in the hands of users to have electrodes passive phenomenon, in order to activate the battery charge deep deep discharge cycle three times. In fact, this issue into a deep charge is not is to Filling 12 hours of the issue. Then my other films article, “On the phone battery charging time” has already answered this question.
★ ★ ★ answer is sufficient and does not require 12 hours.
Early phone nickel-hydrogen batteries because of the need to complement and trickle charge process, to achieve the perfect filling enough, and may need about five hours, but also do not need the 12 hours. The lithium-ion rechargeable inspiron battery constant current constant pressure Is a decision of its deep-charging time without 12 hours.
The lithium-ion battery Some people may ask, since the constant pressure phase of the current lithium-ion batteries gradually decreased, when the current is not small to infinitesimal when the charge is the real deep. I have to draw constant pressure to reduce the current stage of the time Curve, it conducted a number of curve fitting and found that this curve can use 1 / x function of the way and close to zero current, actual test lithium-ion battery itself because the self-discharge phenomenon, and this can never reach the current is the .
To 600 mAh Latitude D500 battery as an example, set up to the current 0.01 C (that is, 6 mA), the 1 C charging time is not more than 150 minutes, then set up to the current 0.001 C (that is, 0.6 mA), it may be the charging time of 10 hours — – Because this precision instrument issues, has been unable to obtain accurate, but from 0.01 C to 0.001 C, as calculated by the capacity of only 1.7 mAh, to the use of more than seven hours in exchange for it is only less than three thousandths of the Capacity is of no practical significance.
Moreover, there are other ways of charging, such as pulse charging the lithium-ion battery to achieve the 4.2 V voltage limitations, it is not closing the smallest current judgement stage, after 150 minutes in general it is a full 100% charge. Many phone With the pulse charging.
It has been using a mobile phone display sufficient enough, then Zuochong to recharge the phone to confirm the sufficient degree of saturation, the less stringent testing methods.
Zuochong first real test showed that green light is not sufficient enough or not a basis.
★ ★ test lithium-ion battery charge enough or not the only way is the ultimate test is not in charge (or discharge) a state of the lithium-ion Latitude D600 battery voltage.
The so-called constant pressure decreases current stage of its real purpose is to gradually reduce the resistance of the battery charge current and because of the additional voltage, when the current small to 0.01 C, for example 6 mA, the current internal resistance by the battery (usually in the 200 Cents within the EU) was only 1 mV, it that when the voltage is no current state of the battery voltage.
Second, the phone does not necessarily mean that the reference voltage Zuochong the reference voltage, cell phone Latitude D800 battery that charge enough to Zuochong, Zuochong not think enough has been sufficient, but to continue charging.
