Notebook battery is something more important, its status is directly linked to a mobile environment in the absence of power in the ability to work. Batteries for laptops is also a major consumer of parts so related to the maintenance notebook battery and wise use are also frequently discussed topic. However, some users maintain some of the understanding is wrong, the following should do something to explain. Sony vgp-bps8 battery
Nickel-metal hydride batteries are now equipped models have basically will not see, the universal application of a lithium-ion batteries. General lithium-ion battery cycle life of 300 to 500 charge-discharge. But this does not mean it can only rarely use the extended life battery. Cells of origin as factors in the physical work environment can influence, but the main reason leading to the loss of cells caused by oxidation of the battery internal resistance increases, which explains why Many users complain that they are fully recharged in use why suddenly had no electricity. It may therefore be understood that the problem is that when the end of the assembly of the battery production line, its internal life, the clock, then start walking, even if you do not set aside the battery, it can be to a certain extent, the loss rate of only delaying the battery. However, in other words, if the battery still sits on the side of the meaning of laptops mobile speak?
Material for lithium-ion battery cathode is generally formed by a lithium-active compounds, the negative electrode is a particular molecular structure of carbon. Common Cathode Material for key elements of LiCoO2, charging, added to the sony vaio vgn-fz battery positive pole of electric potential to force the release of compounds, the lithium ions, incorporate negative elements arranged in a lamellar structure of carbon. Discharge, lithium-ion lamellar structure of carbon precipitation and re-cathode combination of compounds. Lithium-ion movement generated a current. Although the principle of chemical reaction is very simple, but in actual industrial production, the practical problems must be considered much more: the cathode material additives required to maintain multiple load-discharge activity, the electrode material If not, who should design the molecular structure of the class to accommodate more lithium-ion battery; fill in the electrolyte between the positive and negative electrodes, in addition to maintaining stability, but also need to have good electrical conductivity, reducing the resistance of the internal battery.
Although lithium-ion batteries for low-nickel cadmium battery memory effect, the memory effect of this principle is that the crystallization in lithium batteries will have little reaction. However, the capacity of lithium-ion battery charge after repeated discharge will continue to decline, its causes are complex and diverse. Is mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ions on the hole to accommodate the structure will gradually collapse, taken from a chemical standpoint, is the material anode active is passive, there is another side to form a stable compound. Physics will appear on the cathode material to fall off gradually, etc., in short, which ultimately reduces the sony vgp-bps13 battery charge-discharge process can be free to move many lithium ions.
Overload and excessive discharge, lithium-ion batteries will be positive and negative cause permanent damage, from the molecular level of intuitive understanding, an excessive discharge of carbon anode will lead to excessive release of lithium-ion shows the lamellar structure collapsed, over – Rechargeable lithium-ion battery will go too hard in the carbon negative, causing some of the lithium-ion batteries can not be released. Therefore, the lithium-ion batteries are usually equipped with charge-control circuit discharge.
Not suitable for temperature, lead to lithium-ion battery inside the reaction of other chemicals that we do not want to see both of the lithium-ion batteries are put in place between the negative temperature-controlled protection by a diaphragm or electrolyte additives. In the battery temperature in a given case, the composite membrane electrolyte membrane hole closed or degeneration, increased resistance of the internal battery until the circuit, the battery is no longer to warm up to ensure that the battery charging temperature is normal.

And loads of deep-discharge lithium-ion batteries can improve the real capacity? According to experts, the answer he did not make sense. Experts say that even the so-called triple full charge-discharge prior to use of “activation” in their knowledge of
Notebook Computer lithium-ion batteries are generally the management of the chip and chip load control. What chip running a series of records, there is capacity, temperature, identity, charge state, the values of firing rate. These values are in use will gradually change. Personally believe that the instructions for use in notebooks in the “Use a month should post a full load” approach to a role is now to set those records where the wrong values, making the burden of Battery control and the nominal capacity of the battery match the real situation.
Responsible for controlling the main control chip, the battery charging process. Lithium-ion battery charging process is divided into two phases, phase constant current fast charge (when the LED on the battery in yellow) and constant voltage stage down (the battery indicator blinks green. Constant current phase of rapid charging, the battery voltage is gradually increased voltage standard battery, and then transferred to constant pressure in the control phase of the next chip, the voltage does not increase to ensure that no overload, battery current, with the rising gradually weakened to 0, and the ultimate end load.

Statistics smart energy consumption by recording the discharge curve (voltage, current, time) can calculate the battery power of the sample is what we read in the battery information inside World Heritage. Worth. The lithium-ion batteries in repeated use, the discharge curve will change if the chip has not been an opportunity once again read out a complete discharge curve, which is calculated from the electricity that is not true. Therefore, the need to support deep discharge to calibrate the battery chips.
A good battery maintenance is required, so many people have asked how to protect a battery but it will not be early retirement for life on this problem. As the battery life is primarily determined by the number of charge cycles in order to avoid frequent use of the battery can be said that one of the most fundamental way, that uses the power of the environment as far as possible does not use batteries.
This leads to a question, that is, if energy use when the battery removed from the machine, it is indeed a problem that people in the head. However, the condition of high load and high temperature accelerated the decline in battery capacity. I now invite all imagine that if you do not remove the battery, the laptop because of the role of the charging protection circuit, so that the battery is maintained at 95-100% of the charge state to a high when the battery in which the temperature at least 30 ° C, so if it is hot, the temperature will be higher, so the stability of the supply alternating current, we should try to remove the battery to the using computers. If you are planning a long period does not use sony vgp-bpl8 batteries, charge the battery to 40% should be placed in a cool place after the save. If the battery is fully charged, will be placed at high temperatures, so that the battery will cause damage. Because load of 100% within 60 ° C environmental conservation, 3 months after the battery capacity has dropped by 40%. Set aside for the preservation of the battery should be at least one month will be used once the battery Zhuangshang Qu, recharged to prevent the loss of activity of the ion.
Similarly, dust and moisture also acts as a battery killer role, they will destroy the circuit of the battery and accelerate the oxidation of the internal battery, so for those of long-term preservation of the battery You can place a layer of thin sheets of low-grade dust and breach of the humidity.
In addition, lithium batteries how reasonable prices and dump? As lithium-ion battery that can power a small memory effect is negligible, so it loads half of the injury is not too great, and his fear most is the excessive discharge (full discharge). Lithium-ion batteries often the result of low flow excessive battery can be left in advance, such as bios discharge, discharge procedures, and even connected to the discharge bulb is the best way to do see no alternative but to not try. So, for lithium-ion hp compaq nc6120 batteries need not wait until the charging 0%.
To summarize, the maintenance of the battery are a few suggestions:
1. No need to ensure that whenever a new full release END electric charge;
2. A period of time to make a protection circuit placed under the control of the profound power of the battery charge to change the statistics, but it will not increase the actual capacity of the battery;
3. A long time without the battery must be placed in the shade to weaken its internal autonomy, the reaction rate passivation;
4. Protection circuit is also capable of monitoring battery discharge, in the long term without the battery must be charged to a certain degree of power to prevent self-discharge of batteries for storage in the discharge of excessive lead to excessive damage to the battery.
In fact, there is not much to take into account the use of the battery of attention, in other words, is the need did not have much effect. The number of times a cell can use the differences are mainly coming from the battery itself, the making of individual differences rather than use. Choose a reputable brand of notebook PCs is the use of long toshiba pa3634u-1bas battery life in the only future of the security.
