Prevent the proper use of laptop battery battery explosion
Prevent the proper use of laptop battery battery explosion
The quality of recent books discuss the battery is very busy. Now the battery is really, as some articles, like what has become full time bomb? Even do not think so, Dell 1691P Battery a long time, books for mobile work or rely on the battery. Then we should do the proper use of batteries?
1, for the first time to charge the battery if you want more than 12 hours?
You may purchase books at the inspection machine, the clerk will tell you first need to charge more than 12 hours to fully activate the battery. In fact now the battery needs? Currently books are basically battery lithium ion battery, Ni-MH battery only then only so long time to fully activate the battery. The books now are equipped with an internal lithium battery management chip, as long as the battery voltage reaches the rated voltage across the chip will cut off the charging circuit, and then charging down a waste of time and energy.
2, when using an external power supply is not necessary to remove the battery?
Many friends like external power supply when the battery discharge hope that this will extend battery life. Actually, this is not necessary, if the battery is fully charged, even if not remove the battery not to cause the battery to overcharge and damage and cell health, because the battery management chip is now escorting it. And some books if you remove the battery, hardware not reach full speed in the applications you run a large slow when there are obvious sense. If you experience a sudden power outage, you remove the battery, then there is no way to save time the information was being processed. On the contrary, if not remove the battery, you could easily save the information being processed. Negligible loss compared to the battery, I believe that the information being processed in time saved for you it should be something more important.
3, battery time will not remove it alone, is not able to extend the battery life?
Some of our friends that do not use batteries, remove the battery stored separately, you can extend battery life. In fact, the idea is very one-sided. As determined by lithium own characteristics, in fact, lithium batteries, as long as about production lines, the aging process has already begun. This may explain why one did not charge an electric battery had the books, why HP pavilion dv9000 battery three years will be completely scrapped. Objective point, the same batteries and ink cartridges is a consumable, you can not expect the battery to the same hardware as the general books can be used for many years.
4 books a long time do not use if the battery should be how?
Nothing more than a lot of friends, office and home use of books, which more than two external power supply can be found without batteries, and only go out when using battery power. As a few opportunities to use the battery may be a lot of friends, how to store the battery and headache. If your battery does not use a long time, I recommend that you charge the battery about three percent retained around, and then the battery impervious oiled paper wrap, placed in the sun can not direct and cool, the Department can. But I have to remind here that these methods only slowed the rate of aging batteries just can not stop the aging.
5 books how long the battery charge and discharge time is better?
Many of my friends think that too many frequent charge and discharge the battery will shorten its life, and the time to maintain a high capacity battery is also unfavorable, making many friends were puzzled. In particular, the use of batteries for more than friend, I thought a month cycle (that is, the whole process of charging and discharging) time is better, so that neither loss of activity of lithium ion would accelerate aging, but also activate the part of the activity is not strong ion.
6, to what extent the battery discharge books should be charged?
May be a lot of friends that books should be full discharge of the battery can be charged, and this is the error of books one of the battery for everyday use. Those days, because there are serious NiMH battery memory effect, charge must be filled full impact on consumers. The lithium battery is not the same every time if you put the battery power completely finished, then you are still early for the battery to remove it it. We usually use the battery when the remaining 5%, we should charge the battery up. If the battery has aged very powerful, you can try to charge the battery in order to activate the part of all the emission capacity. However, the depth of fully discharge or discharge (refers to the power into the 3%), but not too frequent that the number of books will further accelerate the aging batteries.
7, batteries for batteries, OK?
As the original battery is high, some friends, etc. After the battery end of life would choose to replace the batteries, the battery again to achieve the purpose. Replacement batteries for the thing, I personally think that can be said that eyes of the beholder, the wise see Compaq R3000 battery in the matter. Due to our current market is a bit confusing on batteries, a large number of false core, the secondary core flooding the market, so a good business to find a good replacement batteries is really not easy to do. For the improper range from life is not long, heavy laptop battery explosion is caused. The author based himself who changed the battery batteries, hard to find a reputable business, for a large-capacity Sanyo batteries. After 58 charge-discharge cycles, so I use very satisfied so far. Guer all the best in advance to replace batteries more asking around to find some good word of mouth business is important. Abundant in the budget, I was recommended to choose a bigger capacity, better brand of batteries.
Read more than seven, the proper use of books you have an idea of the battery bar.
About battery life
Now generally use the hang-ion laptop batteries, nickel hydrogen batteries and nickel-cadmium batteries have basically no longer in use, the difference is the hang-ion battery memory effect significantly less than the other two. Although the memory is not obvious hang-ion battery, can easily charge and discharge, but the random discharge or affect their life. So if there are no special circumstances, to avoid arbitrary charge and discharge the same, then hang-ion battery memory effect will not seriously affect the battery block. General hang-ion battery for the 300 to 500 life cycle of charge and discharge, but this does not mean that you rarely use the battery it can be life extension.
Battery as a physical component in the working environment sensitive to various factors. The main result of battery depletion is caused by oxidation of the battery internal resistance increases, which is why many users will complain that they fully charged battery in use Why suddenly no electricity. It may therefore be understood that the problem is that when the end of the battery off the assembly line, it’s an internal clock of life began to move on immediately, even if you do not hold the battery, it can only be delayed to some extent the speed of cell loss has been . But then again, always put the battery side of the mobile laptop meaning that begin?
. About the battery charge and discharge
This in turn will lead to a problem that is in use when the battery power from the machine, remove the. This is indeed an issue people a headache. With our professional testing to observe the state of charge in different habits and ambient temperature after a certain time to conserve battery battery capacity changes. According to the test results show that the high charge state and high temperature accelerated the decline in battery capacity. Well, now you may wish to imagine that the Dell Inspiron 9400 battery is removed, if not what kind of state of 11 notebook computers because the role of the charging protection circuit to the battery to maintain a 100% in 95 high-charge state, at a time when the environment of the battery temperature of at least about 30 ° C, if it is hot weather, the temperature will be higher, you will get what conclusion? Therefore, when using the AC external power supply is best to unplug the battery, or battery state if exposed to heat, their life will be affected.
If you intend not to use long battery, battery charge to 40% should be placed in a cool place to store post to weaken its own internal passive reaction speed, and if the battery is fully charged will be placed in high temperatures, so the battery will cause great damage. 100% charge in the 6o ° c environmental preservation, after 3 months the battery capacity has dropped by 40%. Save the battery for at least a month set aside to put something to use the battery once, and then recharge a battery, so to avoid losing activity ion battery. As the hang-ion battery can power a small memory effect is negligible, so charging it halfway injury is not too great, but it is even more afraid of the over-discharge (full discharge). Keng ion batteries often the result of excessive discharge of the battery can only be discarded in advance, those such as BIOS discharge, discharge procedures, and even connected to the discharge of the way light bulb may not have been less than a force is best not to try. So for hang-ion batteries need not wait for you to go charging when O%.
. Voltage stability is very important
To make use of clean power (not too high or too low voltage) as the external power supply, be careful not to notebook power adapter and power appliances (such as air conditioning) connected with a power outlet. The reason is simple, high-power electrical appliances on or off instantly when the pressure will be formed. If able to do so can matching UPS equipment. UPS is short for uninterruptible power supply is able to provide sustained, stable and uninterrupted power supply for external devices. It can be abnormal when the external power supply, effectively purifying power, but also a sudden interruption in the supply sustained period of time when computers and other equipment to the power supply, so you can have ample time to cope with a sudden situation.
. Need to pay attention to small problems
Dust and moisture are the same as a battery killer role, they will destroy the battery circuit board and accelerate the oxidation of the internal battery, so for those long-term preservation of the battery, you can put on a layer of film to low against dust and moisture. Do not rain Sony VGP-BPS5 battery recharge the battery. Rainy days often thunder, lightning caused by the current moment in terms of impact on the battery is extremely unfavorable.
