1. When no external power supply, if at the time the work situation for the time being less than the PCMCIA card slot, first proposed in order to remove the card to extend batcl50l , travelmate 290 life.

2. At room temperature (20-30 degrees) for the best of temperature, the temperature is too high or too low operating environment will reduce life.

3. Can provide a stable power supply in an environment where the use of laptop computers, will remove the can be extended by the life is simply not true. ASUS notebook computer on, when the full power rechargeable batteries, rechargeable batteries in the circuit will automatically shut down, so will not have been sufficient.

4. Proposed a three-month average of power correction action.

5. To minimize the use of the number of travelmate 4000

The number of charging and discharging a direct bearing on the life of each charge a to retire a step forward. We proposed to make full use of external power supply,

6. The use of an external power will be removed.

Some users often several times a day VGP-BPS9 in Plug Power, and notebook computers equipped with a, to do so, the greater the damage to the. Because each access to external power supply is equivalent to charging a, on the nature of the Zheshou.
7. Exhausted after the electricity charge and avoid charging time is too long

No matter your notebook to use nickel-metal hydride or lithium-electric power, it must be exhausted before sufficient power (electricity consumption of less than 1%), which is to avoid the best way to the memory effect. Li-electric memory will have the same effect, but its memory effect than Ni-MH small number of them.

8. Note the use of normal

Normally used to prevent exposure to prevent damp to prevent the erosion of liquid chemicals, travelmate 2300, aspire 1680, aspire 1410 to avoid contact with metal objects, such as access to happen.

Laptop purchase Notes

The laptop life – as no more than 3-4 years, it may be in the process of users are most likely to be replaced. Two years later the use of laptop computers, consumption will find more and more rapidly. If possible, can replace the old batteries for new batteries to ensure the stability of the computer work.

When the need to replace notebook batteries, preferably with a selection of models to replace the. However, if the old computer is to use nickel-metal hydride batteries, in order for longer-powered, of course, can also be specified by the computer user’s manual or manufacturer’s recommended selection of models of lithium batteries. Although the nickel-metal hydride batteries because of cheap, but there is memory effect, but also in the same capacity next-to-weight ratio of lithium batteries, lithium batteries and have no memory effect, light and power for a long time, and other advantages, has become a laptop travelmate 4500 standard . At this stage to use the notebook computer manufacturers of lithium btp-arj1btp-44a3,asus a42-a3

due to the different power supply in time there are certain gaps and friends in the process of selection should be noted that different brands of batteries in the difference between the best of several brands compare.
In addition to the performance of the manufacturers supply a statement of the time, but also pay attention to the needs of its capacity. capacity is usually AH (ampere-hour, ampere hour) calculation of the current notebook computer equipped with the most common is about 4000AH, and ordinary cell can be sustained for more than 2 hours. In addition to the power supply by the time the whole Computer power and heat dissipation, and other factors, the screen size (the bigger the more power), screen brightness, as well as the implementation of the work of all time will affect the power supply .

Now the prices of notebook batteries in 1000 up and down the ocean, accounting for about notebooks to 10% of the total price – about some of the ultra-thin models and even higher. The warranty, security of 3 months, half a year of security, but also the longest for 1 year; The reason why the warranty period is short because the notebook supplies belonging to the vulnerable, the frequency of recharging is a constant, A small one. Moreover, the notebook lcbtp03003 ,aspire 1300 and other hardware, there is no room for repairs can only be replaced. For such a long period of warranty products (OZ), were invisible on the increased burden on manufacturers, so the purchase of laptop before the must ask the warranty period and conditions.

In addition, the purchase of second-hand laptop when not forget to try its built-in can be sustained for a long time and more work. Under normal circumstances, used in 2012 after sufficient power in notebook computers, Ni-MH can be some support for the work of the computer about 1 hour, lithium-ion can support nearly 3 hours, but relative to the terms of this new The request is already very low, less than the indicator shows a view from near the end of life.
Notebook of the causes of damage
Laptop btp-apj1 , btp-aQj1life is longer, often dissatisfied with the necessary and sufficient electricity, and even shows the has been damaged, the specific performance of the resistance is bigger in charge at both ends when the voltage rise faster. This charge was easy to control the line has been judged to be filled, the capacity of natural decline. As the larger internal resistance, discharge when the voltage drop, fast, so the system can easily mistaken for lack of voltage, less power consumption. Batteries found in the relatively short-time working hours, should take corresponding measures.

Notebook computers are specifically designed for mobile computer, it goes without saying that the importance of the battery. The battery is a delicate consumables, as it has a memory effect, the effect of discharge, and only a limited number of rechargeable (Li-ion VGP-BPS9 for about 400 or so), plus the notebook dedicated high-capacity lithium batteries is very expensive, so Peacetime use, in particular, should pay attention to maintenance. Not pay attention to the maintenance of the barbaric use, make your laptop battery life of the rapid decline. I see a lot of second-hand laptop battery can only insist on less than 20 minutes is a long-term consequences of not pay attention to the proper use of the! The following on my own experience, we should talk about how to defend our beloved books … … the battery. First of all types of batteries, we should be aware that the laptop’s battery at present there are mainly two: lithium batteries and nickel-metal hydride batteries. a, Ni-MH battery Ni-MH battery is a product of the relatively backward, are being eliminated, commonly found in second-hand laptop and a number of "million" China-made models. Ni-MH battery with the shortcomings of memory effect, battery capacity is relatively small, the time required to charge longer. The advantage of the number of rechargeable more generally up to 800 times more than some of the technology to improve the product can be as high as 1,200 times or so. What is memory effect? Regular use of rechargeable batteries you will be aware that Ni-MH battery should be completely exhausted after the electricity in charge, or because of the incomplete chemical reaction and reduce the chemical activity, that is, if your acer btp-43d1 power not useful End, on the charge of battery to carry out, the battery’s total capacity will reduce the rechargeable, battery life will be shortened. Memory effect to a certain extent, is reversible, in other words, we can be of some ways to eliminate the memory effect, bring it to reduce the power loss. However, these methods are very limited, in the event of a memory effect is not completely eliminated. Therefore, the use of nickel-metal hydride batteries friends must note that the battery used up as much as possible, conduct charge. b, lithium battery compared with the nickel-metal hydride batteries, lithium batteries to a number of advanced. Lithium batteries also have a memory effect (some magazines that lithium batteries do not have the memory effect, it is wrong), but the lithium battery memory effect much smaller than the nickel-metal hydride batteries, and to eliminate more than good. Lithium batteries are characterized by: do not have a clear memory effect, acer travelmate 220 battery capacity is far greater than Ni-MH btp-58a1, charging a relatively short time, but it was also shortcomings is clear that lithium batteries can only charge about 400 to 700. Most notebook computers used lithium batteries, lithium batteries and is keep the technical progress, and therefore I can buy laptops, as far as possible to consider lithium batteries. Note the clear cell type, let’s take a look at how to use the Prevention of Cruelty to our battery: 1, the minimum use of battery. When you use the battery? Desk? Bedside? Car? The hotel? The author believes that unless it is a power not found, for example, in the car on the train, field and other places can not use the btp-58a1, acer btp-60a1, but the use of AC power. Keep in mind that the battery is a consumable items, charge a small one, if you use the battery every day, then your batteries in about a year and you have to say goodbye (to count such ah, a day, 365 days once or twice a charge , Is almost 400 times a year or so, the lithium battery life will come to 400). You can look at your laptop warranty card: no matter what the brand is used, the battery warranty is up to a year (the cunning businessmen!), I recognize, of course, if you are in bed, with your ultra-thin notebook A novel look at the computer in a trailer behind the long line of AC power is a really nasty things, but taking into account the price of a new battery in 1000 to 3,000 yuan, I think I’ll wait for the poor or you forget to put up with: ) 2, the use of AC power, battery to get down to avoid frequent battery charge and discharge. And you think different, even if you do not use the battery, which will own some of the electricity consumption, which is called discharge effect. General lithium batteries per day to release its own 0.2 percent of the electricity, and the Ni-MH battery will go from 2 to 4% of the electricity. Effects of discharge is every minute of every hour going. The laptop charging circuit, once detected the battery power has not filled, it will immediately charge, so you can imagine, the use of AC power, due to the effects brought about by the discharge process and the power consumption of notebook acer travelmate 240 battery, acer btp-42c1 charging circuits The charging process has been carried out alternately, may be an hour battery charge and discharge scores, so that the battery on the considerable damage. Many famous international brands such as IBM, hp, Sony, Toshiba and so on in the design of computer time to consider this issue very well, such as IBM laptop battery will discharge monitoring until the discharge of more than 3% of the total electricity consumption when Will be a one-time charge. However, some domestic brands – I will not name here, and poor design make this issue a number of models on a very serious, which is why some friends bought a new machine, a few months down the travelmate 240 battery has not been used on how Almost can not charge it! Therefore, if your laptop is not a very famous brand, in order to better security in the battery when not to take it down for good. 3, a new notebook computer for the first time start, the battery should be a 1% -2% of the electricity (which is the international practice, if you buy a notebook computer battery is already full of open, please note: it is absolutely Is not only the opening of the new machine! Sure it was used!), Then you should not external AC power, let the machine run out of battery power and shutdown. Then once the battery is full of electricity, and electricity and then shine again filled. This cell was active on the complete inspired. If you yield to the temptation of easy and skip this step, the battery will total electricity consumption to a certain extent. Although this will not affect the very serious, but I believe that at their own expense to buy the laptops for every fellow battery performance and on this point of time. 4, due to the long-term care not to use so that battery life substantially reduced, that is, with serious memory effect, we can take to the laptop battery discharge sufficient way to a certain extent this problem. The discharge method is as follows: remove the AC power, use battery-powered, and then open the computer, and many brands of notebook computers are low-voltage protection, that is, if the battery power is too low to force the closure of the computer. This feature is good, but we will not fully discharge the battery. Therefore, before entering the Bios (different brand of notebook computer into the Bios of different ways, be aware that when they look at the boot prompt), the closure of the power management, preservation from the post. Restart, restart Windows before the start screen that appears, press the pause button, making the computer to stay in the boot screen. Then do nothing until the computer’s battery run out of electricity so far off. This process lasted about 1 to 3 hours, so that the battery power shine on the full. The acer btp-550p is full again, take a look at the use of the time is not longer? (Note: This is a significant memory effect of the old acer btp-52ew , acer btp-63d1, if you are using a new laptop battery, it is no good!) 5, if carried out on the battery discharge, still to no avail , Or to the battery discharge method is too complicated, you do not, how do? Oh, I let you teach a trick to the ultimate nirvana – the battery discharge software! IBM’s software, which discharge very easy to use, it can be said of it is something rotten into something wonderful. I have had a P166mmx notebook computers, cell only 15 minutes, after the IBM software discharge after discharge, it can even insist on watching a VCD! So that battery life has decreased substantially friends may wish to try the software may give you a big surprise Oh! The IBM software can be downloaded from the ftp site above. The address is ftp://ftp.pc.ibm.com/pub/pccbbs/mobiles/isbr01ww.exe. The download is an executable file isbr01ww.exe, it will automatically generate the implementation of a startup floppy disk. It starts with the system, we can achieve the automatic discharge. Concrete steps are as follows: (1) the implementation of this document isbr01ww.exe: Insert a floppy disk as required, according to the carriage return, followed by self-extracting process will generate a startup floppy disk and. (2) floppy disk with this guide to restart the computer, the screen appears Starting pc-dos … … (Note: The above operation by the AC power provided.) (3), and then unplug the AC power supply by tips, procedures for automatic discharge the acer btp-44a3 until the machine Self-closing, said the discharge has been completed. (Note: When you see zero percent do not shut down the machine, it is necessary to wait for the closure of its own) (4) AC power plug, and then guide the computer floppy disk, the autoexec.bat automatically refresh operation procedures, ask you if you , Selected "yes", according to the carriage return, the process will soon return to the dos prompt A:>, that have been completed. (5) to turn off the computer, but it is not pulling AC power, to charge the battery until the green light so far. (6) more than repeat the process 3 times to get the best results. 6, if the above methods do not line … … 5 minutes of silence, please, your battery has not saved … … Wait! Do not rush to buy new batteries, many second-hand computer business to provide all notebook batteries for the "core" services. That is, through the shell to replace the battery inside the batteries, the batteries so that you rejuvenated. Usually for core prices, according to the battery, 200 to 700 yuan between this than to buy a new battery is much cheaper, and the result was not to buy a new battery and almost. But you have to be careful if you js-for-one old batteries, it would be a big loss. The notebook’s greatest strength lies in its mobile performance. Have maintained a good, durable power of the laptop batteries, you can make anytime, anywhere, to work instantly and easily enjoy the high-brings you the convenience and freedom. I hope that the experience can bring you some real help and convenience.

Japan’s Sanyo Electric on September 23 that its 2008/09 operating profit of solar cells is expected to be greater than previously estimated, thanks in the first half thanks to booming demand.

Sanyo Electric former deputy director of the Career, 7-hong said that in September to maintain strong sales of solar cells, and the previous quarter but increased by 50%. In oil prices and climate change concerns, the demand for solar cells are growing rapidly.

Sanyo Electric was the seventh largest solar cell manufacturers, competitors including Germany’s Q-Cells, Sharp of Japan and China’s Suntech Power.

Sanyo Electric has not announced a profit of the solar cell business, but covers a whole battery of the rechargeable laptop battery business, accounting for the year 2007/08 the company’s overall operating profits in recent quarters.

How to correctly to the cell phone lithium  inspiron 6400 problems has been a good deal of readers called or wrote to a friend asked how correctly to the cell phone lithium battery, it seems this is a problem we all more concerned about the issue, I would like to focus on will answer this question: to buy a new cell phone lithium inspiron e1505 charging three times before How long will it take? A lot of friends that the charge should be 12 to 14 hours in order to activate dormant cells in many businesses in the same is true when consumers purchase said. In fact, this issue does not have a conclusion, while I personally think that there is no scientific basis in fact three times before and after the charge is the same charge, there are 3 to 4 hours is sufficient. First, we all know that when over-charging lithium batteries, over-charge or discharge, excessive discharge current when the battery life and have a great capacity for damage, and may even cause an explosion or deformation of the battery, so it is in the internal lithium battery Have set up electronic circuitry to protect the batteries. When the gd761, td347 
over-charging, over-discharge current is too large, will be cut off connections with the outside. Like some friends, as reflected in: cell phone charger in the boot, the phone has come in automatic shutdown will cause problems. In other words, the initial battery charging, low voltage, and when a call came in, the phone to ring, it is necessary to maintain a certain degree of power. In the low-voltage, battery current will increase, too much current caused by the battery protection circuit moves to cut off the battery connections with the outside, resulting in cell phones turned off automatically. Second, to enhance the efficiency of the rechargeable, lithium battery to first-current electricity to the current charge of 90%, battery voltage of 4.2V, it almost takes about 2 hours; and then to a small voltage current charge until after the inspiron battery is fully charged Internal circuit protection movement, which takes about half an hour, taking into account the battery, the charger Products of individual differences, rechargeable lithium battery with 3 to 4 hours is appropriate. For example, I tested the battery charging process, Siemens 6618: 0.5 hour rechargeable battery power consumption to 50%, shows that “310-6321 ”; charge 1 hour, the battery up to 80%, indicating “8667 Battery”; charge 2 hours, the battery 100%, indicating “A667 Battery”. Taking into account the margin of error showed that power mobile phones and other factors that may charge additional 1.5 hours. There is one more point it should be noted that lithium batteries do not have to be punished by placing the long-term hibernation state, the normal need for the use of pre-activated. After a general 3 to 5 charge, discharge cycles can be activated. According to the first two reasons, we can see that the dormancy of lithium batteries expect for a long time to activate the charge is meaningless. Because the battery is full (after about 2 to 4 hours), lithium Latitude D505 protection circuit has been on the move, to cut off the external power supply. Due to the protection of the circuit, rechargeable lithium power for a long time although no harm, but to protect the circuit will start the consumption of energy batteries, circuit protection in case the loss of role, ranging from cell damage, while heavy damage to the cell phone, and then the consequences are afraid to re-envisaged . Therefore, taking into account the mobile phone, lithium 1691P  charger and individual differences, charging three times before and after the charge are the same, only 3 to 4 hours has been a good deal of readers called or wrote to a friend asked how to correctly The cell phone lithium battery, it seems this is a problem we all are more concerned, I would like to focus on will answer this question: to buy a new cell phone lithium battery charging three times before How long will it take? A lot of friends that the charge should be 12 to 14 hours in order to activate dormant cells in many businesses in the same is true when consumers purchase said. In fact, this issue does not have a conclusion, while I personally think that there is no scientific basis in fact three times before and after the charge is the same charge, there are 3 to 4 hours is sufficient. First, we all know that when over-charging lithium Latitude D610 , over-charge or discharge, excessive discharge current when the battery life and have a great capacity for damage, and may even cause an explosion or deformation of the battery, so it is in the internal lithium battery Have set up electronic circuitry to protect the batteries. When the battery over-charging, over-discharge current is too large, will be cut off connections with the outside. Like some friends, as reflected in: cell phone charger in the boot, the phone has come in automatic shutdown will cause problems. In other words, the initial battery charging, low voltage, and when a call came in, the phone to ring, it is necessary to maintain a certain degree of power. In the low-voltage, 3149C  current will increase, too much current caused by the 40y6795 battery  protection circuit moves to cut off the battery connections with the outside, resulting in cell phones turned off automatically. Second, to enhance the efficiency of the rechargeable, lithium battery to first-current electricity to the current charge of 90%, battery voltage of 4.2V, it almost takes about 2 hours; and then to a small voltage current charge until after the battery is fully charged Internal circuit protection movement, which takes about half an hour, taking into account the battery, the charger Products of individual differences, rechargeable lithium battery with 3 to 4 hours is appropriate.

After a general 3 to 5 charge, discharge cycles can be activated. According to the first two reasons, we can see that the dormancy of lithium batteries expect for a long time to activate the charge is meaningless. Because the PC764, TD175 battery is full (after about 2 to 4 hours), lithium battery protection circuit has been on the move, to cut off the external power supply. Due to the protection of the circuit, rechargeable lithium power for a long time although no harm, but to protect the circuit will start the consumption of energy batteries, circuit protection in case the loss of role, ranging from cell damage, while heavy damage to the cell phone, and then the consequences are afraid to re-envisaged . Therefore, taking into account the mobile phone, lithium 5081P  charger and individual differences, charging three times before and after the charge are the same, only 3 to 4 hours.

In the mobile phone, both from a technical point of view or from the assessment of price considerations, the battery is very important. Value today, the market is sales of mobile phones, used batteries has been completed from a nickel to cell lithium dell inspiron 6000 battery
transition. Perhaps it is because of cell phone battery had just completed a nickel to cell lithium battery revolution, the people’s awareness of lithium batteries are not uniform and in many cases incorrect to say and practice is quite popular. As a result, know a little knowledge of lithium batteries, lithium batteries have the right to use it is very necessary.

First, the type of lithium battery:
At present, the market used rechargeable batteries are nickel metal hydride (Ni-MH) and lithium-ion (Li-ion) are two types. Lithium-ion batteries have been in mass production of liquid lithium-ion battery (LiB) and lithium-ion polymer battery (LiP) two. Therefore, in many cases, the battery mark on the Li-ion and lithium-ion battery is a must. But that is not necessarily liquid lithium-ion battery, is also possible that the polymer lithium-ion battery.
Lithium-ion battery is a lithium dell inspiron 9300 battery , dell inspiron 9400 battery improved version of the product. Lithium batteries have a long time ago, but the lithium is a highly active (remember that the its position in the periodic table?) Of the metal, it is not safe when used often in charge when burning, the burst , Then there is the improved version of the lithium-ion batteries by adding the element lithium can inhibit the active ingredients (such as cobalt, manganese, etc.) so that the lithium power to achieve real security, efficient and convenient, and the old lithium batteries also Basically eliminated. As to how to distinguish them from the battery on the logo will be able to identify, lithium batteries for Li, lithium-ion dell 310-6322 for Li-ion. Now, notebook and mobile phone use of the so-called "lithium batteries", in fact, are lithium-ion battery.
The basic structure of modern batteries, including cathode, anode and electrolyte of the three elements. As a battery, lithium-ion battery with the same three elements. Lithium-ion technology in general or the use of inorganic colloidal liquid electrolyte, it needs to accommodate case solid combustible active ingredient, which increased the battery’s weight and cost, but also limits the size and design flexibility. In general, liquid lithium-ion secondary battery is the minimum thickness of 6mm, and then to reduce the more difficult.
The so-called polymer lithium-ion batteries in three of the main structure at least one or more polymer materials used as the main battery system.
A new generation of polymer lithium-ion polymer batteries in the extent of the already very high, so the shape can be shaped and thin (the thinnest 0.5 mm), of any size and any shape, and greatly increased battery design flexibility , In order to meet product demand, made in any shape and capacity of the battery. At the same time, lithium-ion polymer battery unit of energy than current lithium-ion batteries in general increased by 50% of its capacity, charge and discharge characteristics, security, operating temperature range, cycle life and environmental performance in areas such as lithium-ion dell d5318 are relatively large The rate increase.
Currently on the market by sales of liquid lithium-ion (LiB) in the over-charging the battery case, thus easily lead to the breakdown of the fire safety situation, it is very dangerous, so to install the necessary protection to ensure that the cell line IC will be no over – Charge. The polymer lithium-ion battery, this type of cell relatively liquid lithium-ion battery in terms of good-resistant properties of charge and discharge, so the protection of Canada’s IC circuit requirements can be relaxed. Also in charge, the polymer lithium-ion batteries can be recharged using IC will be current with the lithium-ion rechargeable battery used in CCCV (Constant Currert-Constant Voltage) charge means the time required for comparison, can shorten the waiting time for many.

Second, the use of lithium-ion battery
This is part of the focus of this article, we discuss three points.
1, for a new battery charge
In the use of lithium batteries should be noted that for a period of time after the battery is placed into hibernation, lower than normal capacity at this time, the time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycle of the battery can be activated, the resumption of normal capacity. As the battery lithium own characteristics, its decision is almost no memory effect. Therefore, cell phone users in a new lithium battery in the activation process does not require special methods and equipment. Not only is the theory that, from my own practice, from the very beginning, the use of standard methods of charging that "activation" is the best way.
Lithium dell g5266 for the "activation", a large number of claims: the time to charge more than 12 hours, repeated three times to do in order to activate the battery. "The first three necessary and sufficient to charge more than 12 hours", it is obvious from the nickel battery (such as nickel-cadmium and nickel metal hydride) inherited. This is why it can be said is the beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics of a very big difference, but also very clear to tell you that I have had access to all the serious official stressed that all technical information and charge-off will discharge lithium, especially lithium liquid Ion dell latitude cpi battery , dell inspiron 8200 battery causing great harm. According to the charge and therefore the best time and method of charging standards, in particular for not more than 12 hours of super-long charge. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of charging.
In addition, the lithium battery in the phone or battery charger will automatically stop after a charge, there is no electricity nickel charger for 10 hours 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 the quality of safety, so your dell inspiron 8000 battery will be in the long-term hovering on the brink of danger. This is also another charge against the chief reason.
In addition to certain mobile phones, the charge for more than a certain amount of time, if not remove the charger, this time not only to stop charging system, will be the beginning of discharge – charge cycle. This is perhaps the manufacturer has its own purpose, it is clear that on the phone and battery / charger is the life span of a negative. At the same time, long charging would take a long time, often at night, and to our country’s power grid situation, at night in many parts of the relatively high voltage, but also volatile. Said earlier, the lithium battery is very delicate 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, can not be ignored other aspects of a lithium that is not the same for over-discharge, over-discharge of lithium dell inspiron 8100 battery is also very unfavorable. This leads to the following question.
2, in normal use when the charge should be
In our forums, often see this as the number of charging and discharging is limited, so should the cell phone battery power used up as much as possible and then charge. But I find on a lithium-ion battery charge and discharge cycle test table, on the life cycle of figures is as follows:
Life cycle (10% DOD):> 1000 times
Life cycle (100% DOD):> 200 times
DOD is the depth of the discharge of which the initials. Can be seen from the table, the number of rechargeable and about the depth of discharge, 10% DOD at the time of the life cycle than 100% DOD’s a lot longer. Of course, if the actual charge equivalent to the total capacity of the relative: 10% * 1000% * 100,100 = 200 = 200, which is the complete charge and discharge, or better than some, but in front of friends do say that some of the amendments: normal Under the circumstances, you should have a reservation in accordance with the remaining dell inspiron 4000 battery , dell inspiron 4100 battery power and then run out of filling the principle of charging, but if your battery is expected in the first 2 days you can not adhere to the whole day, should start on time charge, of course, if you are willing to back A charger to the office and when Bielun.
And you need to charge in order to cope with the anticipated upcoming busy communications will lead to an important event, even if there are a lot of battery power over time, then you just charge ahead of time because you do not have a real loss "1" sub-charge cycle life , That is, "0.x" times, but often this will be a very small x.
The remaining dell inspiron 2500 battery power and then run out of charge to the principle does not mean that you go to the extreme. And charging the same length of a widespread view that "as far as possible the cell phone batteries run out of power, it is best to use automatic shutdown." This is only a matter of fact on nickel dell latitude cpx battery, to avoid occurrence of memory effect, unfortunately, it is also spread of lithium batteries on this. It has been too low because the cell phone battery warning appears, do not continue to use the charge has been used in automatic shutdown of the case. The outcome of this case, the phone was in charge of the boot in and there was no response, had to give customer service overhaul. In fact, this is due to the battery as a result of excessive discharge and led to the low voltage that does not have the normal charge of the boot and conditions.
3, Li-ion battery for mobile phones in the right way
To sum up, I lithium batteries used in mobile phone charging and discharging of the most important tips are:
1, in accordance with the standards and procedures, charging time, even before the three to do so;
2, When the phone prompts when electricity is too low and should start charging as much as possible in a timely manner;
3, lithium batteries do not need to activate the special method, in a normal cell phone use in lithium would be natural to activate. If you insist on spreading the use of "three times before the 12-hour long activation charge" approach, in fact there will not be the effect.
As a result, all 12 hours long pursuit of the lithium dell latitude c600 battery and rechargeable cell phone used in automatic shutdown, are wrong. If you are used to be in accordance with the wrong done, please correct in a timely manner, perhaps not too late.
