How maintenance actually be right? This problem has plagued many loyal users of notebook computers, including me. After reviewing some information, the recent opportunity to consult a professional in the electrochemistry of a PhD and a well-known domestic Acer aspire 5742 battery, deputy director of the Institute. Now a number of recently acquired knowledge and experience to write out to satisfy you for readers.
Lithium-ion dell wu946 battery cathode materials are usually composed of active compounds of lithium, the negative is a special molecular structure of carbon. Common cathode materials mainly composed of LiCoO2, charging, added to the HP Compaq Business Notebook NC6400 Battery positive pole of the electric potential of compounds to force release of lithium ions, embedded negative elements arranged in lamellar structure of carbon. Discharge, the lithium ion from the lamellar structure of the carbon in precipitation, re-cathode combination of compounds. Lithium-ion movement generates a current.
Although the principle is very simple chemical reaction, but in the actual industrial production, the practical problems need to be considered much more: the cathode material additives needed to maintain the activity of multiple charge-discharge, cathode materials needed to design the molecular structure level accommodate more lithium ions; fill in the electrolyte between the positive and negative, in addition to stability, but also has good electrical conductivity, reducing the battery's internal resistance.
Although lithium-ion HP Compaq Business Notebook NX6125 Battery with little memory effect of nickel-cadmium batteries, memory effect is the principle of crystallization in lithium Ibm Thinkpad z60m Battery is almost no reaction. However, lithium-ion battery capacity after repeated charge-discharge will continue to decline, its causes are complex and varied. Mainly positive and negative changes in the material itself, from the molecular level, the positive and negative ion on the hole to accommodate the structure will gradually collapse, clogging; from the chemical point of view, is the active anode material is passive, there's another side to form a stable compounds. Physical cathode material will appear on the gradual falling off, etc., in short, ultimately reducing the Apple m8416g/A Battery will be free to move in the charge-discharge process of lithium-ion number.
Overcharge and over discharge, lithium-ion Acer Aspire 5720 Battery anode cause permanent damage, from the molecular level, intuitive understanding, excessive discharge of carbon anode will lead to excessive release of lithium ion and makes its lamellar structure collapse, excessive Rechargeable lithium-ion will too hard to go into the negative carbon structure, while making some of the lithium-ion no longer be released. This is the lithium-ion HP Compaq Business Notebook NC6400 Battery are usually equipped with charge and discharge control circuit causes.
Not suitable for the temperature, the internal lithium-ion HP Compaq Business Notebook NX6110 Battery will lead to other chemical reaction of the compounds we do not want to see, so many of the lithium ion battery between the positive and negative temperature with protective membrane or electrolyte additives. To a certain temperature in the Dell inspiron 9400 battery case, the composite membrane electrolyte membrane hole closed or degeneration, the battery internal resistance increases until the circuit, the battery is no longer warming, to ensure that the Dell latitude d630 battery charging temperature is normal.
And deep charge and discharge lithium-ion Dell vostro 1400 battery can improve the actual capacity? Experts clearly told me that this is meaningless. They even said that the so-called three full charge and discharge before using the "active" in their knowledge of two doctoral years, could not understand what this is necessary. Why do so many people, however, after the Battery deep charge-discharge
Information in the label will change the capacity it? Will be mentioned later.
Notebook computer lithium-ion Dell xps m1330 battery are generally charged with the management chip and control chip. Which management chip in a series of registers, there is capacity, temperature, ID, charge status, discharge frequency values. These values are in use will gradually change. Personally, I think, for use in notebook computers in "one month after the full charge and discharge should be a" major role in the practice is to fix these registers should be in the wrong value, making the hp laptop battery charge control and battery nominal capacity consistent the actual situation.
The main control chip charge control the battery charging process. Lithium-ion hp pavilion dv8000 battery charging process is divided into two phases, constant current fast charge phase (battery indicator light yellow) and the constant current phase (the battery indicator light flashes green. Suzhou Fest computer accessories, maintenance, technology, service http://www.buy-laptop-battery.org/ constant current fast charge phase, the battery voltage gradually rises to the standard battery voltage, then under the control chip into the constant voltage phase, voltage will not rise in order to ensure that no over-charge, current rise as the Sony pcga-bp2nx battery is gradually weakened to 0, and the final charge.
Statistics chip power consumption by recording the discharge curve (voltage, current, time) can calculate the sample battery, which is in Battery
Information in the reading of wh. Value. The lithium-ion Dell Inspiron 14 Battery after repeated use, the discharge curve will change, if the chip has been no opportunity to read a complete discharge curve, the calculated power is not accurate. So we need to calibrate the battery charge-discharge deep chips.
Finally, I view the maintenance of the Dell Inspiron 15R Battery is:
1 no need to make sure that each time a release is finished re-charge;
(2) a period of time to do a protection circuit is placed under the control of deep charge the Dell Inspiron N5010 Battery with correct statistics, but it will not improve your battery's actual capacity;
3 long-term without the battery, should be placed in a cool place to weaken its internal their passive reaction speed;
4 protection circuit is also able to monitor the Hp Mini 110 battery self-discharge, long-term without the battery, the battery must be charged into the battery to prevent self-discharge in storage in excess lead to over-discharge damage.
In fact, the battery is not too much to take into account the use of attention, in other words is taken into account there is not much use. How many times a cell can use, and perhaps more different from the manufacture of the Hp Mini 110-1015la Battery itself, individual differences, rather than use. Choose a good laptop brand reputation is undoubtedly a long battery life in future one of the guarantees.
