Laptop Battery Introduction

“How to charge and discharge laptop battery?” Many readers may to question. This issue, we invited experts Xiangjie to laptop battery charge and discharge method. Hp Compaq 8710p battery

In general, then start charging when the charge mode if the option, do not select the fast charge mode (charging mode Express) to avoid premature battery “full”. When the battery is weak prohibit the use of high performance CPU to reduce power struggle. If the computer uses the CPU to support SpeedStep technology, can be easily adjusted performance. SpeedStep program icon is a blue flag, right click on the options to optimize performance that may occur. In Windows XP, SpeedStep program can cause problems, this time can change the BIOS settings for the computer, or use procedures that brand-specific regulators.

Laptop battery components for circuit protection are generally regulator block, control tokens, insurance, and temperature sensors. temperature protection device is generally off, the interior has a fuse (fuse about 130 ℃), used to monitor the work unit voltage regulator. If the process of abnormal discharge, immediately there is a current through the guard temperature fuse blows, the internal circuitry of the battery at that time for the off state, and unrecoverable. If you want to repair only the replacement of the temperature protection, but protective of temperature is difficult to find on the market. Therefore, the high cost of maintaining the battery.

Using the battery will certainly after the loss, so that users will find less and less battery “by use.” If you are a consumer of the battery, you can set special to restore battery performance, as THINK and other phones with the process of power management. If no solution can be 2-3 times repeated charge and discharge to restore. Some people think to unplug the external power source after the battery is full, and then stop until the batteries were exhausted completely discharged the. In fact, not. Battery warning appears after the shutdown state before entering the BIOS does not work, as the computer is off when the discharge really complete. Also, do not start charging a levy on the shoe, preferably every few minutes, then turn, if the charger lights, then start charging display lamp flash, not flash until the time of re- boot.

Nowadays there is the possibility that the market we did not expect the phenomenon is not the best-selling price range of about 3,000 low-priced models, but the price of segment 4000-6000 yuan. Zhongguancun, in an interview last week, we have several large-scale distributors, their bosses are basically the above consensus. Dell XPS M1330 battery About 3,000 yuan a notebook in their laptops sold  Battery in the ranking general, was the third. However, low-cost notebook market demand is still very large amount, many only on the Internet, Battery typing, has asked a friend to see a large purchase such an inexpensive laptop is still relatively cost-effective.

Manufacturers are now also more emphasis on Dell Vostro 1310 battery low-cost notebook market, even though this part of the notebook is relatively small profit margins, because it is basically red volume manufacturers in this price range have the product on the Battery market, here we take a look at the market more representative products.

However, the price of 4200 yuan should be said that the competitiveness in the market is not strong, significant size alone is not high, we hope Sony VGP-BPL8 Battery that in due course be able to upgrade the machine manufacturers to configure and adjust their prices.

Summary:

In fact, we recommend to you every time when the  Battery product will say how to pay attention not to be taken in the store to buy things do not go see a friend, of course, there are many Internet search before buying a computer’s friends can not help but dealers temptation. Although it is easy, but it does not easily done, Battery some time ago we also met a distributor, their psychological qualities comparable with 007, reported that low-cost less than the cost reported 2,000 yuan, less than Jiaoqian say when you can sell This situation goes without saying that the general consumer is the expert in this field is also difficult to tell in the end is true or false. But VGP-BPS9  Battery we tell you that one principle, as long as the price outrageous, do not the letter, nor do directly for a judge.

In addition, in some cell phones, collecting more than a certain time if it starts not remove the charger to stop, this time only for billing system discharge – charge cycle. Perhaps it is the manufacturer of this approach, its own purposes, it is clear that the Sony VGP-BPS8 battery Sony VGP-BPS9 battery and cell phone charger is a disadvantage in terms of life expectancy. At the same time, long charging would take advantage of a long time, often at night, but our power grid situation, at night in many places higher than the voltage, but also volatile.

As noted above, the lithium batteries is very precious, and it is more than nickel in the electric charge and discharge aspects of fluctuations in the ability of the resistance is much less, so this brings additional risk. In addition, another aspect can not be ignored is the lithium battery is also not suitable for over-discharge Sony BPS8 VGP-BPS8 , over-discharge of lithium batteries is also very unfavorable. This leads to the following questions.

Iin normal use it should start charging. Recharge in our forums, often the argument that because the number of loading and unloading is limited SONY Vaio VGN-FZ battery, so that the phone battery to be used as much as possible. But I found one on the lithium-ion battery charge and discharge cycle test table, on the lifetime of data is as follows:

Life (10% DOD):> 1000 times

Life (100% DOD):> 200 times

DOD is the depth of discharge, which the English abbreviation. Can be seen from the table is the depth of the charge and discharge times, 10% DOD is lifetime than the 100% DOD for much longer. The course when they meet the actual costs relative to the total capacity: 10% * 1000 = 100,100 * 200 = 200%, the latter a full charge and discharge, or better than some, but to say to friends that some of the changes: In normal case You should have a spare battery is almost empty, in accordance with the principle of the left side carry disposal charging again, but if you can not use your Sony VGP-BPS10 Sony BPS10 , in your first two days, expect that in the last entire day, if it was timely for free start, of course, if you are willing to return the charger to the office again a different matter.

And you need to recharge for busy with the next expected communication needs will result in a major event about , although there are a lot of battery power over time must, then you just charge ahead, because you can not really be lost “a” sub-charge lifetime, ie “0.x” times only, and is often very disturbing.

Run the battery is empty and then fill the rest of the principle do not want to go to the utmost. And as long as the loading of a widespread view that “as far as possible the cell phone battery runs out, it is best to use automatic shutdown.” This is really only practical on nickel batteries, is the goal, the memory effect occurs on Sony VGP-BPS8 Sony BPS8, to avoid, but unfortunately it is also of lithium batteries for this to spread. It is too low because the cell phone battery warning appears, still does not burden continues to use the sample that was used in the automatic shutdown. The results in this case, cell phone fees from, and later in the no response, had to contact customer service to give overhaul. In fact, this is because the battery caused by excessive electrical discharges in low voltage, so that the normal cost and the boot and conditions.

for lithium batteries cell phones right track. In summary, I have used lithium batteries in cell phones charging and discharging, the most important tips:

1, are consistent with the standards and procedures to, charging time, even the first three to do so;

2, when the phone asked if the current is too low, we should try to now be loaded on time;

3, do not enable lithium batteries to the particular method in a normal cell phone use lithium batteries such as VGP-BPS8 are naturally active. If you insist on promoting the use of “the three previous 12-hour long activation charge” approach, in fact, there is no effect.

Hence all the pursuit of super-long 12-hour lithium battery cell phone use and the integration of the practice of automatic shutdown , false. If you have previously done in accordance with the false argument correct, please in time, perhaps not too late.

Of course, cell phones and chargers to protect themselves and control circuit of high quality cases is the protection of lithium batteries are still guaranteed right. Therefore, the charge is central to the understanding of the rules, and in some cases also make some concessions. For example, you can find in your cell phone the night before an extra bed, you can also start charging before going to bed. Is the core of the problem, you should know what to do the right thing, and not deliberately wrong to do so in accordance with.
