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.

We know that the phone battery is the source of power, which is the driving force mobile phone, no battery-powered, the phone is a scrap iron, a high-capacity high-performance batteries, cell phones not only can give long life, but also can protect Phone circuit, making the phone a long time to the high efficiency of the work, but it is likely there will phone unexpected damage. And to our players, the laptop battery factory in the performance of the time, it has been qualitative, the size of its power, performance is good or bad, are determined by the battery itself, in this context we can not artificially changed, but This is not to say that we get the battery, after it is not done. The use of mobile phones are lithium-ion rechargeable battery, the use of the unused storage capacity, need to be added rechargeable power. Do not underestimate this aspect charge, a good battery charger and the correct method of charging, the battery can maintain a long period of standby time, but also to extend battery life. Further step that can also play a protective effect on the phone. On how the charging method, there will be regular in the forum audience asked, after a period of time to their actual use and reference, I summed up the following points:

1. Lithium battery factory in general, manufacturers to activate processing, and pre-charging, the inspiron battery has more than electricity, to buy a new phone is the lithium-ion battery, then the first three to five times as charge adjustment period, more than 14 hours should be sufficient , To ensure the full activation of lithium-ion activity. Lithium-ion batteries no memory effect, but has a strong Sui, should be fully activated, can we guarantee that the future can use the best performance. The first charge on this issue, I also consulted with Samsung’s technical staff, gave me the answer is that Samsung’s original batteries, the factory has already done a full activation processing, do not have to use a long time to activate the charging method Lithium-ion activity, as long as the first rechargeable battery, while the latter is full, can be used. I would like to Samsung’s technical staff that should be able to convince.

2. Some automated intelligent rapid charger when the lights change direction, the fact that only 90 percent full. Charger will automatically change to slow recharging the Inspiron 600m battery  is full. Do not put the charger immediately cut off the power supply, preferably to fill a section of the battery, the time will be full of battery after use, otherwise it will shorten the time.

3. Before charging, lithium batteries do not need to discharge, can not discharge, the current production of lithium battery chargers are not discharge the function, if we can adjust the speed of the charge, the proposed charge when you try to slow Chong Chongdian to reduce filling fast ; Whether slow or fast filling the time not to charge more than 24 hours. Otherwise, the battery is likely to be a long time because the power supply have a tremendous flow of electronic and burn batteries.

4. There are many users in charge of the cell phone when driving, in charge of the process, a cell phone because of the use of external discharge, because of the rechargeable Latitude D500 battery  and power supply inside, is likely to lead to disorder voltage of the cell phone circuit boards Will be fever, if there are calls, will have an instant return to current, the internal components for mobile phones damage.

5. The life of the battery decided to repeatedly charge and discharge the number of lithium batteries can continuously charge and discharge about 500 times around the battery after the performance will be greatly weakened, the batteries should be avoided as far as possible, Fang Yu, all rechargeable End, otherwise the increase in the number charged with , Battery performance will gradually weaken, the battery standby time it is not difficult dropped.

6. Do not expose the Latitude D600 battery  under high temperature or cold, like Sanfu day, the phone should not be placed on the sun, and withstand the scorching sun exposure, or get air-conditioned rooms, blowing straight in the air-conditioned places. When charging, returning current products, batteries a little fever is normal.

7. If the battery of the phone too long without using, preferably to the phone for the maintenance department to make a cell activation processing, can also use a DC their constant pressure, voltage adjustment for the 5 ~ 6 V, current 500 ~ 600 mA reverse connect battery . Note that Yi Chuji liberalized, most can be repeated three times, after such treatment, reuse original Charger “period of adjustment” charge.

8. The charge is not a good time longer, has failed to protect the circuit after a battery charge should be stopped, otherwise they will be in hot or overheating affect performance. Battery charging theory calculation of the time are as follows: The battery charger power divided by the output current can, for example: a 800 MAH electricity for the batteries as an example, the output current Charger for the 500 MA then charging time is equivalent to 800 MAH/500MA = 1.6 hours, of course, this is only a theory, the calculation of time, when the Chargers showed that charging is completed, even the best batteries to about half an hour, about the meeting time. Lithium-ion Latitude D800 battery  charger to be selected for, otherwise it will amount to less than saturation point, affect the performance of play.
