The use of lithium-ion battery

The use of lithium-ion battery


pay attention to three points:

1, how to charge the battery for a new

The use of lithium Acer Laptop 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 batteries can 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 in theory, this is the case, from my own practice, from the very beginning, the use of standard methods of charging that "activation of natural" approach is the best.

For the lithium battery "activate" problem, 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 necessary and sufficient to charge more than 12 hours" is obviously from the nickel Laptop Battery (such as nickel cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said to misrepresent the very beginning. Lithium batteries and nickel battery charge and discharge characteristics are very big difference, but also very clear to tell you that I have gone through all the serious official stressed that technical information and charge-off will discharge lithium batteries, especially lithium liquid 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, lithium batteries 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 batteries in full, on the white charger is also sufficient. And we can not guarantee that no one battery charge and discharge protection circuit features and never change and the quality of safety, so your Acer BTP-73E1 Battery will be at risk of long-term around the edge. This is also another charge against the chief reason.

In addition, 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 battery life is a disadvantage. At the same time, long charging would take a long time, often at night, but to our power grid situation, at night in many places higher than the voltage, but also volatile. As already said, the lithium batteries 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 Acer BTP-550P Battery is also not suitable for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following question.

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. But I found one on the lithium-ion battery charge and discharge cycle test table, on the cycle life data is as follows:

Cycle life (10% DOD):> 1000 times

Cycle life (100% DOD):> 200 times

DOD is the depth of discharge in which the English abbreviation. Can be seen from the table, rechargeable number and depth of discharge, 10% DOD cycle life than when the 100% DOD should be much longer. Of course, if the actual charge equivalent to the relative total capacity: 10% * 1000 = 100,100% * 200 = 200, which is the complete charge and discharge is better than some, but in front of friends do say that some of the amendments: normal circumstances, you should have a reserve power in accordance with the battery run out and then filling the remainder of the principle of charging, but if your acer BTP-44A3 Battery is expected in the first two days you can not adhere to the time of the day, they should have started on time charge, of course, if you are willing to back the charger to the office and when.

And you need to recharge 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 you just charge ahead, because you are not really lost, "a" sub-charge cycle life , that is, "0.x" times only, and often this x will be very small.

Run out of battery power and then filling the remainder of the principle is not want you to go to the 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 of lithium batteries on 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 due to the excessive discharge as a result of the battery voltage is too low a result that does not have the normal charge and boot conditions.

3, the correct way for lithium batteries

To sum up, the use of lithium Acer BTP-42C1 Battery in the 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, should try to begin charging a timely manner;

3, lithium batteries do not need to activate the special method, in normal use of the machine will naturally activated in lithium batteries. If you insist on spreading the use of "the three previous 12-hour long activation charge" approach, in fact there will be no effect.

Therefore, all the pursuit of super-long 12-hour rechargeable lithium batteries used and the integration of the practice of automatic shutdown, are wrong. If you have previously done in accordance with the wrong argument, please correct in time, perhaps not too late.

4, the use of lithium batteries of fire

Some people might be familiar from Acer BTP-63D1 Battery began to lithium batteries. In fact, it is being used in many household appliances. Needless to say, lithium battery efficient, lightweight, and so its benefits are open to promote the use of rapidly. But, you know, use carelessly, it will make you provoke "fire" upper body?

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, in recent years are being phased out are used in alkaline batteries and manganese batteries, widely used in many high-end home appliances and mobile handsets.

Unlike lithium batteries are used in batteries and alkaline manganese dry battery of the zinc chloride and potassium hydroxide aqueous electrolyte, which uses an organic solvent. Lithium Battery Cathode use of manganese dioxide, lead fluoride, thionyl chloride and other materials. Anode used in lithium metal foil anode with the general use of zinc chloride batteries compared to ionization tendency of strong, positive and negative voltage difference big, so that the work of improving the effectiveness of lithium batteries.

However, lithium 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. It is reported that Japan has in recent years there were several causes of Li-ion battery heat caused by the family fires burning.

So why lithium batteries fever, burning it? Many of the original lithium battery 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 Acer BTP-52EW Battery placed in dry, low temperature at the proper custody, to prevent and avoid inappropriate use of lithium battery fires caused by household accidents.
