All the necessary protection features, such as: to protect the battery during charging to prevent the circuit overcurrent, by limiting the discharge voltage of the battery laptop battery to extend battery life.
Preservation Methods
Lithium-ion power battery fully charged, after the need to save. In more than six months can be stored at 20 ℃, showing that lithium-ion battery suitable for preservation at low temperatures. It has been suggested that rechargeable battery placed in the refrigerator interior preservation, is indeed a good idea. Existence of lithium-ion power battery self-discharge phenomenon, prolonged preservation will lead to battery depletion and the destruction of the internal structure of the battery, reducing battery life. Therefore, long-term preservation of the lithium-ion battery should be every 3 to 6 months make up power once, that is charged to voltage of 3.8 ~ 3.9V (Li-ion battery voltage of 3.85V the best save so) is appropriate.

Notes

The use of lithium-ion battery, pay attention to three points:

1, how the new battery?

The use of Inspiron 1100 lithium-ion battery should be noted that a period of time after the battery is placed into hibernation, lower than normal capacity at this time, use of time has also come to shorten. However, lithium-ion battery is easily activated, as long as after 3-5 times the normal charge-discharge cycles the battery can be activated to restore to normal capacity. As the lithium battery's own characteristics, its decision is almost no memory effect. The new lithium batteries so the user during the activation process does not require special methods and equipment. Not only the theory that, from a practical point of view, from the outset on the use of standard method of charging that "activation" approach is the best.

For the lithium-ion power battery's "activation" issue, many say is: recharge time must be more than 12 hours, repeated three times to do in order to activate the battery. This "The first three charging more than 12 hours to charge" was obviously from the nickel battery (such as nickel cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that a beginning of miscommunication. Lithium-ion power batteries and nickel battery charge and discharge characteristics are very different, all the serious official stressed that technical information C1295 and charge-off will discharge lithium batteries, in particular liquid lithium-ion battery causing great harm. Accordance with the standard charge and therefore the best time and the standard method of charging, in particular, not to carry out more than 12 hours of super-long charge. In addition, the lithium-ion battery or the charger will automatically stop after the battery is full charge, there is no electricity nickel charger for 10 hours of the so-called "trickle" charge. In other words, if your lithium-ion power batteries in full, on the white charger is also sufficient. But no one can not guarantee that the battery charge and discharge protection circuit features and never change and the quality of fail-safe, so the battery will be a long time at the brink of danger. This is also another reason to oppose the long charge.

In some machines, charging more than a certain time, if they do not remove the charger, this time not only to stop charging system will start to discharge - charge cycle. Perhaps the makers of this approach has its own purpose, it is clear that in terms of 1X793 battery life is a disadvantage. At the same time, long charging would take a long time, often at night, and to the grid situation, at night in many places higher than the voltage, but also volatile. As already said, the lithium-ion battery is very precious, and it more than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this brings additional risk.

In addition, another aspect can not be ignored is the lithium-ion battery is also not suitable for over-discharge, over-discharge of the battery is also very unfavorable. This leads to the following questions.

2, normal use should be when to start charging?

Because the number of charging and discharging is limited, so should be used up as much as possible the electric battery recharge. However, regarding the 6Y270 lithium-ion battery charge and discharge cycle test table data is as follows:

Cycle life (10% DOD):> 1000 times

Cycle life (100% DOD):> 200 times DOD is the depth of discharge of which the English abbreviation. Can be seen from the table may be the depth of charge and discharge times, 10% DOD cycle life than when the 100% DOD for much longer. Of course, if the actual charge equivalent to the relative total capacity: 10% * 1000 = 100,100% * 200 = 200, the latter a full charge and discharge, or better than some, under normal circumstances, you should have reservation in accordance with the remaining battery the principle of sufficient power and then run out of charge, but if the first two days can not be expected to persist throughout the day, when they should start on time charge, of course, if you are willing to carrying a charger to the office again a different matter.

The need to charge in order to cope with the anticipated upcoming busy communications will lead to an important event, even though there are a lot of battery power over time, then just charge ahead, because there is no real loss "1" sub-charge cycle life, which is "0.x" times only, and often this x will be very small.

Run out of battery power and then filling 312-0068 the remainder of the principle is not extreme. And long, like charging a widespread view that "as far as possible the machine run out of battery power, it is best to use automatic shutdown." This is really just practice on nickel batteries, The purpose is to avoid the memory effect occurs, unfortunately, it is also spread on the lithium-ion battery of this. It has been because the machine is too low battery warning appears, still do not charge to continue to use the example has been used in automatic shutdown. The results of this case, the machine later in the charging and starting there was no response, had to give customer service overhaul. In fact, this is because of power

Pool due to excessive electrical discharges cause voltage is too low, so do not have the normal charge and the boot and conditions. 3, the correct way for lithium batteries

To sum up, on the lithium-ion battery in use charging and discharging, the most important tips are:

1, in accordance with standards and procedures, charging time, even the first three have to do so; 2, when there is low power consumption machine when prompted, it should try to begin charging a timely manner; 3, lithium batteries do not need to activate the special method, in the the machine in normal use Latitude D610 lithium batteries will naturally activated. If you insist on spreading the use of "the three previous 2 hours long activation charge" approach, in fact there will be no effect.

Therefore, all 12 hours long pursuit of the charge and the lithium-ion battery used in the practice of automatic shutdown, are wrong.

4, the use of lithium batteries of fire

Some people might be familiar from mobile phones began to lithium-ion power batteries. In fact, it is being used in many household appliances. Needless to say, lithium-ion battery efficient, lightweight, and so its benefits are open to promote the use of rapidly.

Lithium batteries have a body of light, high efficiency, low temperature (-40 ℃) etc., 0.3mm thick, stamp-sized lithium battery can be used continuously for more than five years, widely used in many high-end home appliances and mobile handsets.

Lithium-ion battery currently being used is different from the manganese batteries and alkaline dry batteries of the zinc chloride and potassium hydroxide aqueous electrolyte, which uses the organic solvent using lithium-ion battery cathode manganese dioxide, lead fluoride, chloride sulfur and other materials. Anode used in lithium metal foil anode with the general use of zinc chloride Latitude D600 batteries compared to ionization tendency of strong, positive and negative voltage difference big, so increasing the work of lithium-ion battery performance.

However, lithium-ion power batteries are often in the course of fever, burning phenomenon, the impact of light by the host to use, in serious cases will also cause a fire burned down the host. Japan has taken place over the cause of lithium-ion battery heat caused by combustion of the family fire.

So why lithium-ion battery heat, burning it? The original lithium-ion battery in the many materials in contact with water, after severe chemical reaction can occur, and release a lot of heat leading to fever, burning phenomenon. Manganese dioxide lithium battery cathode, only a small drip can dip fever phenomenon. Lithium thionyl chloride batteries in contact with water in the generation of hydrochloric acid and sulfur dioxide, while the release of heat, several factors make life lithium batteries to become the "fire" and therefore people are using lithium batteries must pay attention to water-proof, anti - wet. A variety of host disabled, they should remove the batteries placed in dry, low temperature at the proper custody, to prevent and Latitude D520 avoid inappropriate use of lithium battery fires caused by household accidents.
