With the popularity of notebook computers, notebook battery increasing frequency, but you know notebook Sony DSC-T5 battery voltage, capacity, power core is the relationship between what it? Here let us introduce to you one by one.

In the electricity, the common voltage, battery capacity and other concepts to measure the properties and performance of the individual. Generally a single battery (including alkaline batteries) and a rated voltage of 1.5V, Nickel-cadmium batteries and nickel metal hydride batteries to 1.2V, while the lithium-ion battery is a 3.6V (some manufacturers of lithium-ion battery calibration rated at 3.7V) , the equivalent of three nickel-cadmium or nickel metal hydride battery voltage in series from a number of common non-rechargeable lithium battery voltage is 3V.

As the individual cell voltage and Sony DSC-T7 battery capacity are very limited, generally require the composition of several cell batteries to meet the actual power needs of different devices. In digital cameras, the most common battery combination is in series, that is, both connected to the battery positive and negative, such as the four 1.2V, 1300mAh battery in series, to form a voltage is 4.8V, capacity 1300mAh battery pack; In notebook computers, batteries generally use the hybrid approach, that is, there are parallel series.

Capacity refers to the size of the battery storage capacity. Battery capacity of the unit is the "mAh", Chinese name is milliamperes (the measure of high-capacity batteries such as lead batteries, in order to convenience, general use "Ah" to represent the Chinese name is Ah, 1Ah = 1000mAh). Figure 4 in the GP super battery rated capacity is 1300mAh, if 0.1C (C is battery capacity) or 130mA of current to the battery discharge, then the battery can last 10 hours (1300mAh/130mA = 10h); if discharge current of 1300mA, the only time that supply about 1 hour (the actual working time for the actual capacity of the Sony DSC-T70 battery while there are some differences between individual differences). This is the ideal state analysis of the actual work of digital equipment was not always possible when the current is constant at a value (in digital cameras as an example, because the LCD screen will be operating current, flash and other parts of the open or closed while the occurrence of larger change), so the battery can power a device is only about the value of time, and this value can only be estimated through practical experience.

Then how to calculate the number of batteries it?

Calculate the number of batteries, depending on what your battery is batteries, generally have lithium with hydrogen power, labeled LI-LON is lithium, lithium is the core of each power saving 3.6V, or 3.7V for the standard

HI-HM is hydrogen power, hydrogen Sony FE1 battery power is 1.2V as standard. Ordinary hydrogen power, then the subject directly to the battery voltage divided by 1.2, that is, the number of batteries inside

If the lithium battery, it should be except 3.6 or 3.7, which it wants to be divisible, such as 10.8V, which is the core string up three power-saving, and that at least three, and then look at the capacity, if the 4400's, that is, Two energy-saving core parallel, the capacity of each section 2200, which had six power-saving core, if 6600, that is 9, and also the capacity of each section 2200, if 4000, that is 6, indicating a low capacity batteries inside that is the capacity of each section 2000

Peugeot general such battery, 10.8V, Capacity: 3600,3800,4000,4400,4600,4800,5200, these are 6, the capacity of the larger, indicating the greater the capacity of each Sony NP-BD1 battery energy-saving core, but the batteries remain the same, again: 10.8V, Capacity: 6000,6400,6600, these are 9, and
Some of 14.4V, the capacity of 4000,4400, which is 8, and this pushed down, is your cell number of the batteries.

Notebook computer lithium-ion batteries are generally charged with the management of chip and controller chip. The "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. "Charge control chips" mainly controlling the Ibm thinkpad t30 laptop Battery charging process. Lithium-ion battery charging process is divided into two phases, constant current fast charge phase (when the battery indicator light yellow) and reduced voltage current phase (the battery indicator light flashes green.
Constant current fast charge phase, the battery voltage is gradually increased to the standard battery voltage, then under the control chip into the constant pressure phase, the voltage will not rise to ensure that no over charge and current as the battery level gradually decreased up to 0, and the final charge. inside the battery There is statistical power chips, will charge and discharge curves by recording (voltage, current, time) can calculate the sample Uniwill 255-3s4400-g1l1 Battery power, this is what we read about in the Battery Information wh. value. The lithium-ion batteries used in many post- the discharge curve may change, if the chip has been no opportunity to once again read out a complete discharge curve, its calculated power is not accurate. so it is necessary to calibrate the battery charge and discharge of deep chips.
I personally think that, in the notebook computer for use in the "use of a month should put a full charge" approach should be the main role is to amend the register where the value of improper, making the battery charge control and consistent with a nominal capacity of the battery the actual situation.
How much of a battery capacity and can use long, decided to manufacture the battery itself, the individual differences, rather than use. A Dell latitude d400 Battery beyond its rated impulse discharge frequency, always to care and attention, will not extend its life. Therefore, the use of batteries, do not be too deliberate to be protected, usually in accordance with the normal use on it.

First: The most important point: Do not change their laptop had been optimistic about the model and configuration! The Acer aspire 4720z battery reason is and read this paragraph if you fancy, and you before this configuration and price are asked a lot of dealers up. Because the notebook market, intense competition, basically you ask the dealer for the price, no profit. Then how should we do? Very simple for you to change models, Imagine you run a day, and also asked about the model, while the dealers through a variety of techniques allow you to buy another machine to see if the weather is also late, and he is running tired, do not want to run out and watch salesman "good" look, think about this paragraph is almost, well, not ask, and then buy it, huh, huh, then you have got a. Because you do not understand this price, you can imagine, after the profits generated from this transformation is absolutely violence, and to use our jargon, at least 1000. If you really liked the salesman recommended the new, it is also very simple to deal with this move, no matter how sales staff to assure you the lowest price was. Must be pulled out and then ask the price of face, asking you know, you do absolutely valuable. Ha ha. Ate a lot of powerful Seller embarrassed psychological prospective customers, make you embarrassed out of his shop, then you become one piece of the object. If you are asked to go out and found that to you before the salesman to change Acer aspire 4920 battery models more reasonable prices, then congratulate you, you encounter a very rare honest sales staff, also waiting for? Buy it in this.

Second: Ask prices also stress that if you start asking about a machine model, for example, ASUS A8, A8 word you just said, then the price you asked, most are very high . Because this case Seller bound to report higher prices, if you say the price is too high, they will say there are many models of it, configure it more, I reported that the XX configuration, you will impress the. The asking price is the correct way: quote accurate models, such as: A8H73SC-SL this way when you ask, as a salesperson, you know you are very clear about, or do not report the exact model so, then they dare not offer a. So the price you ask is very real. There is no sense of chaos rather than the prices quoted.

Third: Do not suddenly asked a very low and it makes your heart feel hot face ultra cheap but wildly excited, huh, huh, in fact, many sales staff is so dry, you buy this machine, right? Look at the price, oh, I be profitable, how should we do? Transition, ah, how to switch it? The first step is to let you report a ultra low price, you one, happy ah, excited ah, such a low price, can not help a good impression on the sales staff has doubled. So, you optimistic, he second step, would certainly say that you saw in the previous machine is not for you how how, how I am right now how you this. Oh, remember Oh, really fancy if he recommended that a new, must go out to ask a few, if you do not change your mind, do not waste your time, let him getting goods with it, mostly to take not come out, because he quoted the price is lower than the costs reported, never even intended to sell it to you, and waste your valuable time, so my advice is: Do not buy one company offering the lowest price. You will gain most disappointing.

Fourth: the configuration of their Acer aspire 4920g battery bullish must understand clearly. If you do not, then find understand the (fear afraid to do staff who pretend to understand, so that the people most vulnerable to Seller Sanxialiangxia to settle, and must find really know very much about the stay by you) because the sales staff it will use your configuration cheat you do not know, it's clear that the same machine, asserted that what more discrete graphics, ah, ah, or what the fancy screen like, let you add money to buy. This client is very sad my eyes. I have personally seen the laptop battery actually was brought alone to increase 2000 sales to sell, and do not understand more than PC users, after all, ah. If you are well configured, the salesman this trick naturally useless.

Fifth: of course, to understand the machine you want to buy gifts, such as Asus some time, S5 is the notebook version of the high distribution free of charge the second battery, of course, if you do not know this information, the salesman will certainly allows you to add a third 500 buying a second battery, did not say the. In fact, promotions like this, the simplest thing, when manufacturers do this type of promotion certainly has its relevant color page Chu Lai do promotional work you understand your PC's stage O'clock in the mind of the Xiao Shou Yuan Zhi Yao obtain a color page, Ji Ben will not be in this trick on a. Of course, some very large home Acer aspire 4310 battery site to find out, the better.

Sixth: a lot of scouring friends when buying notebook computers, very much like some gifts, I tell you, sales staff to send gifts in time, only one principle: the cheapest. So basically all rubbish sent. Therefore, the most intelligent seller will first thing, then talk to sales staff, I do not want these things, you give me less money, huh, huh, do not expect to lose sales staff to tell you the worth, the value the extent of how much money, basically, he said what the value of 100 yuan, the cost of 30 yuan on the good. Can reduce the number, to see how you talk with the salesman Rights.

Notebook's size and weight

Portable notebook computers and desktop biggest difference. Thus, no matter how superior style, too large or too heavy, is not in the notebook manufacturing of mind.

Notebook "light", "weight" of the judgments vary, generally the following can be considered light 1.8kg, and 1.3kg suitable for women around the models, men, the largest not more than 3kg better models. Select lightweight notebook a wise move.

LCD size

In the choice of display, its size is usually considered the primary factor customers. In fact, compared with the display size, the pixel size is more important. The same size display, the pixel is different. 10-inch notebook display (B5 size slim notebook), 13.3-inch (A4 size regular notebook), 15.1 inches (high-end notebook) three models, the models take into account their size and no sense. With 15-inch monitor, one for 1024 × 768 pixels, and one for 1400 × 1050 pixels, purchase a better natural to choose the latter.

Keyboard

Do not use the keyboard as too small. The average desktop keyboard key side of 19mm, while the notebook only display more than 13.3, the bond length to achieve the 19mm. The current widespread use of thin notebooks, the bond length was 14.5 ~ 15.5mm. Battery type and use the time most of the notebook lithium batteries, the use of time based on battery size and capacity will vary, but generally can reach one and a half hours. Although battery life is longer, and this will definitely increase the notebook's weight. Can be said that the weight of the notebook is the LCD, Hp 550 battery and hard disk determined by weight. For frequent use of laptop, you can also purchase high-capacity battery.

CPU

CPU can be said that the heart of notebook. But not just by CPU speed to buy. Because in the Internet, edit text has enough common. Not the blind pursuit of high-speed CPU, which should be chosen for their needs. Should abandon the mistake on the CPU, the same purchase price under the full-featured laptop.

Battery can expand

In addition to notebook memory, the upgrade can not be achieved in general. Although the battery can be expanded, but in practice is more trouble, should determine the socket number and set up. The more idle jack, battery scalability to large, in different ways according to jack the cost of upgrading will be different.

CD-ROM and floppy drive interface mode

High-end notebook equipped with drive, floppy drive, but thin and light notebook is not. That over-used PCMCIA mode, but now many ways to use U ****. USB mode not set up the drive, the boot state can be identified, to use, very convenient. Most notebooks use the IEEE 1394 mode optical drive, it is very similar to USB, faster transmission speeds, commonly used by the people. Special jack is also used in the present more. PCMCIA, USB, IEEE 1394 port or use a slot, just not the case, so much quicker. However, although a quick and convenient to use special socket, there is still fear of high prices, the weight of large defects.

Whether the built-in modem and network card

Now, can not access the computer can not be called in the full sense of the computer. To access, you must install the modem and laptop card. Local function to load the modem has become a trend. Although the method can also use the PCMCIA network card, it is power, not suitable for notebooks, and more than a jack-consuming, so currently used inside a local function.

Battery and memory phenomena (Memory Effect)

The biggest Hp 6700 battery shortcoming is the nickel batteries with memory function, it is the battery fully discharged state to Zai not to charge, which reduces the battery Ying Chong Dianliang, the Hui serious inefficiencies caused by the battery 50 percent. Second, should be forced discharge of nickel batteries, remove one of the cadmium component.

Regular use of laptop's friends may have a most profound realization is the feeling that a laptop to use a certain stage, the screen will appear dark situation. Like this from happening, maintenance terminology, referred to as "dark screen" is primarily aimed at high-pressure plate can not supply electricity to the lamp on the hp 510 Battery LCD screen.
The maintenance industry, we have the LCD screen brightness is not enough referred to as "dark screen" means that the ignition coil failed to supply electricity to the lamp on the LCD screen.
Regular use of laptop computers for people who know there is a small LCD screen on the LCD screen lamp for bright, so dark when the screen caused by many people mistakenly believe that is the lamp burned for-1 on OK, and if the LCD screen lamp pipe is so easy to burn, then I think the manufacturer may more complaint letters, where the failure of the screen to make a dark detailed explanations.
First, the dark screen of failure caused by four points:
1, fluorescent tubes disconnected (normal use of the computer will not be destroyed or broken by the high-voltage lamp, lamp off is mainly due to: computer fell to the ground floor lamp strikes the grave)
2, ignition coil no power supply to the lamp (the motherboard with 3-4 group of voltage for the ignition coil, ignition coil through the chip for the transformer to the lamp post, chip to chip, aging or over-current burn without hp 530 battery electricity output)
3, motherboard no power supply to the ignition coil (the motherboard there are 3-4 for the group to the ignition coil voltage, motherboards, there are two groups-chip output voltage to high voltage board, chip to chip, aging or over-current burn without electricity output)
4, cable disconnect (between the motherboard and the ignition coil has a cable connected for a long time moving LCD screen cable disconnected, resulting in no main electricity supply to the ignition coil on)
These four points are the major problems caused by the dark screen where the points, the first three are more emerged, the fourth point of the opportunities that arise is relatively small, because the connection line is to use a special kind of shield is covered with it and a small number appear to connect line disconnected phenomena. Professional maintenance staff for the detection of each process are essential.

How to correctly understand and use the HP HSTNN-IB44 Battery
1. Notebook computer batteries for use considerations.
"A" want laptop battery longevity, there must be a good start, a new notebook at the first boot with the battery usually about 3% of the electricity, the first time do not use an external power supply, I put the battery inside the power exhausted, until the shutdown, and then re-use an external power supply charge. The exhaustion of the battery power even after charging, charging time must be within 14 hours, repeated three times to do in order to fully activate the battery, in this way can lay a good foundation for future use.
"2" notebooks battery life is measured in terms of the number of charging and discharging. In the absence of necessary, do not enable the battery, if a long time do not use the battery, charging to 50% longer battery placed in a cool place to save. If you enable the battery, you should run out of power after the charging, not in the battery have not used up when they plug in the AC power. When the battery fully charged, it should disconnect the AC input, since overcharging batteries overheating will shorten the battery life.
"3" Generally speaking, today's notebook computers with intelligent battery protection, the Hp hstnn-c29c laptop Battery will not be damaged due to normal operation, but it still may be a result of life to the damage or other special reasons. For the nickel-metal hydride or nickel-cadmium batteries, has a memory effect, if used improperly, the battery discharge time is becoming shorter and shorter or even impossible to recharge.
"4" Lithium-ion battery charging time constant of the way first in order to fast-charge voltage reaches a certain value and then to slow charging constant voltage mode. Notebook computers are often not strictly a constant-current charge of monitoring devices. The system load when a large charge current on small, whereas the large, the current from the AC power adapter power margin decision. Clearly, the system will charge the battery and other components, such as CPU, hard drive, LCD and other competing energy sources.
"5" is to try to discharge a small current discharge operation is slow down and let the CPU, hard disk stops turn, transferred the darkest the hp nc8430 Battery screen (or close the switch off), then do not run any programs until the laptop automatically shut down. The emphasis on small-current discharge is to prevent premature detection of laptop battery shortage.
Generally speaking, deliberate and unnecessary use of batteries in accordance with the method above, the normal office use on it.

Q: battery not long, how do we keep them in good condition?
A: Charge or discharge to 40%, and then on the temperature of 15 to 25 degrees Celsius dry place, Gateway m505 laptop Battery temperature is too high and too low are likely to accelerate cell aging.

Q: The battery does not remove the books to each power supply right?
A: It does not matter, the notebook's battery protection circuit again, full of will not continue charging the

Q: My battery is only a short time, how do?
A: If you have been in frequent use batteries, then it is a matter of aging batteries, which can not be avoided, you can consider switching the battery a Xin Zhong You Huozhegenghuan battery of Dian core; if you do not have battery long-term, may also lead to this phenomenon, this time need to complete discharge (up to fail to boot up), and then full power, repeated several times to activate the battery.

Q: notebook universal power adapter to it?
A: No, there are three obstacles, the first is the notebook manufacturers use various different voltage, such as IBM are 16V, COMPAQ mostly 18.5V, SONY part of the model is 19.5V, are inconsistent. Second, the different needs of current laptop is different from the 2A ~ 5.4A are small machines need less current, a large machine is greater. Third, each company laptop power adapter interfaces are different, it is difficult general. Therefore can not yet common to all notebook power adapter

Q: How should the new charging machines bought it? How do battery maintenance?
A: Lithium (ion) battery is required to maintain a certain electromotive force to maintain its internal chemical activity. Therefore, to achieve full charge when the full release, generally can charge the previous three six-hour or so, time will be tight, like electricity charge to 100%. Necessary and Sufficient to avoid the use of less than 10% of the time to recharge it in time, not to exhaustion, Is this the gateway squ-412 Battery Faner You hurt; Tong Yang when higher than 60% also Jinliang not charge. Application of long-term without the battery to 50% of electricity at room temperature, dry environment preservation.

Q: Why does my IBM laptop when using the battery power is always higher than the brightness with a low first gear?
A: This is random in the IBM power management default settings, the purpose of power:), if you do not like it, can the system control software in the IBM ThinkPad Configuration Utility, select LCD project, then the brightness from the Normal to High can. The Display option in the BIOS which has the same settings. The purpose of this fact is to power.

Q: first use the battery, the first three need to charge 12 time?
A: This is not necessary because the current laptops have improved power management power
Road and charge management system, when the battery reached saturation, the control circuit will automatically switch to the off state, so even if sufficient length of time and then also to no avail.

Q: In order to prevent memory effect, we should run out of power before charging it?
A: Every time charge the battery before discharge is unnecessary and harmful. Practice shows that the deep cell
Unnecessary degree of discharge will shorten the life of the proposed use when the battery is only about 10% can be charged when
Electricity. When the Gateway 8msbg Battery power is still more than 30% of the best to be charged, because the memory effect does indeed exist more or less.

Many friends have been asking the question on the notebook battery, laptop dell wr050 Battery actually I have always said is a necessary laptop accessories, you can try to protect, no need to deliberate care, or to the machine also keep a fast day is not work Why use a strong battery, used laptop as you can simply transfer the chip.

For use, the question is how to recharge it should be said by how much is not too much stress, because it will become very passive, then the user, the actual battery is not so delicate. The use of AC when the battery is still on the machine to also win as you have the. Notebook computer circuit control a lot better than a cell phone, fully charged, it will automatically cut off after the charging circuit for small current loop and in order to maintain the battery charge state, the circuit control design good machines are less than 95% of the electricity began to charge, So you need not worry as the battery plugged in to recharge the ghost will say indefinitely; if the win to save it, suggest you put on in the outside layer of plastic wrap the battery, so the dust can be isolated and placed in a cool place, and then take a regular basis come out with what, rechargeyour batteries, in order to avoid loss of activity of the battery.

There is also a question we have asked more, whether it is necessary to calibrate the battery, how to calibrate the battery? The answer is yes, because the battery in use and charging the instability caused by the battery capacity will decrease, but the decline was not due to aging caused, so proper calibration is able to make this partial loss of the capacity to restore the . Therefore, regular gateway s62044l Battery calibration is very necessary thing, such as 1-2 months time. Such as Compaq and IBM laptop's own power management in BIOS or a program to provide a battery calibration, so use both brands according to instructions that you can be friends. For those who do not provide this feature the brand's users can follow my steps below:

1. The screen saver is set to "None"

2. In the Windows Power Management power scheme will be set to "always open", and related equipment following the closure of all the menu is set to "never"

3. The alarm tab will be "insufficient power warning" is set to 10%, the operation is set to "do nothing"; will be "a serious power shortage alert," set to 3%, operating as a "standby"

4. The screen brightness set to maximum

5. Confirm that all the windows closed, and save all the data before the work

6. Check that the battery charge after more than 80%, unplug the power and all external devices, then if the screen automatically reduces brightness, so please hit it the brightest

OK, you can go to sleep, after discharge notebook will automatically shut down after the power plug for laptop charging, attention must be so completely full before turning on power, and then return to the power scheme settings before calibration.

The aim is to continuous low current discharge laptop batteries, which discharge state in our daily use is impossible to achieve, as the normal state we may make various changes in current operations up and down. IBM, SONY machine can detect that the Hp pavilion dv8000 laptop Battery capacity before and after the change, other machines can download Lu master to see, you will find, little by little restored the capacity of, but here is reminded that if your battery has been caused by excessive use aging, that this temporary solution method is also just no use.

Laptop battery life for notebook computer users are most concerned about, how to make your notebook more energy,

work longer hours, to maximize the dell gd761 Battery? LIVEdigitally introduced a notebook computer power of 10 tips:

1. Lower brightness. Needless to say, to open to the highest brightness is the first killer of laptop

batteries.
2. Do not use an external device. Any USB and PC card devices will consume power.
3. Less open several programs. What kind of doing the procedure, the other off.
4. To keep cool. Ensure that exhaust air is not blocked, especially on your legs when.
5. Turn off unused services program. MSN Messenger, Google desktop search, QuickTime, wireless managers, etc.,

when they do not need them all off.
6. Use hibernation (Hibernate) and not hang (suspend). If your laptop supports hibernation feature, often more

power than the system hang.
7. Adjust energy Manager Advanced Configuration. Two years ago to today's notebook computers are basically

their own energy hp nc8430 Battery
management device, adjusting the configuration, choose more energy efficient models.
8. Carefully chosen applications. Word, Excel, Outlook, and text editor are more energy efficient process. All

Adobe procedures, all of Google's plug-ins are power experts. Games are also very power. WinDVD than Windows Media

Player better. Remember to switch off when put MP3 visually, the best why not just put MP3.
9. Pay attention to your hard drive. Do not use the computer play music, mainly due to the hard disk power

consumption. Some consume more hard disk boot, find the law to see how long after the idle stop switch to the most

suitable for the hard disk.
10. Ready. Well before the plane hp nc8230 Battery system adjustment, etc. on the plane and then would only consume more power.

Well adjusted, so that laptop hibernation.

First get a piece of a new sony vgp-bpl9 battery, many users approach is in accordance with business tips in the first three rechargeable lithium batteries used in 12 hours or more. Online there are many arguments on this fact that for most of laptop batteries is not necessary. Why? Businesses say this is the activity to fully activate the battery, fully awaken a new battery. For this reason it sounds very full and credible, but we have not thought about this problem. If, laptop battery manufacturers have not yet been fully activated on the appearance of words, this is only a semi-finished product can be said. Can not require each user to master the techniques activate the battery, it is impossible in reality. Therefore, in the battery factory has been the company's fully activated. How are users 12-hour rechargeable battery is conducive to the use of it? In this I give a negative answer, the current laptop battery has a good power management circuits, and charge management system, when the battery reaches saturation, the control circuit automatically switches to short-circuit condition, so the next time just a waste of time only. How to activate the activity of the battery does? In fact, the manufacturers for the activation of the battery overload protection in case of no longer charging and discharging of the battery. Therefore, the first three charge 12 hours is unnecessary.
In the second, many users use the sony vgp-bps10 battery very confused, what should or should not wait until the battery is completely discharged before charging. This problem is actually the answer should be like this, if you can do is certainly a good thing, but only if you took the trouble. Of course I have here said is not the over-discharge, over-discharge is definitely proved harmful to the battery, it will shorten the battery life. So when the laptop battery low prompt when a timely charge of. Some businesses have repeatedly declared their lithium batteries no memory effect, this is extremely irresponsible. So when you have more power when the battery is not charging as well as memory effect does exist.
Thirdly, how long should the battery need to do, it is recommended into the 40-50% of the power placed in the low temperature in the shade, the following parameters can explain the problem.
Storage Temperature 40% Charge 100% state of charge state
(0 degree 98% (a year later) 94% (one year later)
25 degrees 96% (one year later) 80% (one year later)
[40 ° 85% (a year later) 65% (one year later)
60 degrees 75% (a year later) 60% (3 months later)
(Percentage of saturation at the time the relative percentage of the initial value),
Of course, the best take the battery out every month with one, can guarantee the good state of preservation battery, not that bad for the loss of damage to the sony vgp-bps8 battery power completely.
Fourth, for use in laptop computers in the "use of a month should put a full charge" approach is necessary. laptop computer lithium-ion batteries are generally charged with the management of chip and controller chip. Management chip which has 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, in laptop computers for use in the "use of a month should put a full charge" approach should be the main role is to amend the register where the value of improper, making the battery charge control and consistent with a nominal capacity of the battery the actual situation. So this kind of work or can not be omitted, after all, a laptop or squeamish high nobility.
Finally the use of talk, how to make the laptops of the battery last longer. Since you bought a laptop is to use it, the battery is one of consumables, will certainly continue with the use of time and move towards retirement. How to make laptops battery life? Power-saving technology? Sleep? Suspend to disk? To reduce the screen brightness? All these methods seem to be able to increase the so-called extended. But you have not thought about, such extended sense? I drove my laptops do not run any programs, do not open the display, not to hard to me, I can not achieve a longer time. May think this absurd practice, laptop is brought to use, not high-sounding ornaments. So the writer in this suggestion is to not care about how good laptop sony vgp-bps8a battery . Perhaps, after two years of the laptop market is another world, your laptops have reached the retirement of the life line

Obtained through a large number of tests: the internal battery resistance with the decrease of battery capacity increases, that is, when the dell inspiron 6400 Battery constantly aging, the capacity continues to decrease, the battery's internal resistance will continue to grow. Through the test results, we can conclude that the whole group by comparing the internal battery resistance, or to track changes in monomer degree of battery internal resistance, you can find the whole group behind the battery, the battery internal resistance by tracking changes in monomer degree of , you can understand the extent of aging batteries to achieve the purpose of maintaining batteries.
For VRLA batteries, if the internal resistance than the reference value (average) increased by 20%, and battery performance will be decreased to a level low. This value is also the IEEE STD recommended to take immediate corrective measures (discharge test or replace) standard. IBEX1000 the basis of this proposal benchmark alarm value is set to 20%.
Accordingly, VRLA battery capacity dropped to 80% or less when the battery is like aging degree of the △ T in the graph, like the time can not be predicted, while the capacity decay rate will be more blocks, while the resistance within the increase will be faster. We propose therefore that a timely replacement of batteries in order to enhance your company's battery system reliability.
So far, the practical application of the discriminant battery state of health of the method is only recommended to use IEEE standard, so we recommend that, when the internal battery resistance increased by 20% or more, you should consider this unit to take corrective or replacement of the battery of measures.
The resistance test has the following advantages:
a, small and lightweight, on-line measurement. The internal resistance of handheld portable compact tester to detect when the battery internal resistance is not necessary to remove the battery from the system, direct-line testing, will not affect the power system work and to avoid the risk of power system.
b, the workload is small, easy to operate. Resistance tester detection time is usually 2-3 seconds to test a battery, a group of 200 test battery generally be only about half an hour. Just connect a good battery, internal resistance tester will automatically test and save the data, it is also very easy to operate.
c, to discover behind the battery, in the reduction of maintenance personnel to maintain the growing workload of cases, and by resistance testing can quickly look behind the dell 1501 Battery, the improvement of maintenance efficiency, and ensure system security operation.
D, resistance tests can completely replace the check-discharge test?
Check the discharge method that is 100% C of the depth of discharge, it has the capacity of the advantages of accurate and reliable testing, therefore, is still the world's most reliable detection method of battery performance. Check the discharge method that is, fully discharge capacity of the test is to test the battery capacity of the most direct and reliable method, whether online or offline for testing, must be set the backup power supply as a precautionary measure to ensure the safety of the system.
Resistance tests on-line measurement will not affect the normal operation of the system, while testing to spend a short time, routine maintenance very convenient.
Because the resistance test by comparing the battery internal resistance of the entire group differences or to track single cells at different times of the resistance changes in the way, check the battery level of aging, and therefore it can not be 100% accurate measurement of capacity. However, due to check the discharge, there are many shortcomings (see background C), therefore, resistance testing can make up for the shortcomings of checking discharge detection, by comparing the identifying or predicting the aging of the batteries, making batteries for routine maintenance is very convenient and effective, by looking behind the battery , combined with single-discharge test, significant savings in maintenance costs, so that back-up power system more stable and safe operation.
E, measurement of resistance using what method?
DC test: the use of battery discharge to the test apparatus, to measure added to the pressure drop on the battery internal resistance, and then divided by the discharge current draw battery internal resistance, the average test current are large, reaching about 50A-80A.
Benefits: test accuracy, consistency, good
Disadvantages: test current, the probe must be connected with the battery pole stability, if the exposure will be hit bad arc, there are security implications.
AC Testing: Testing equipment will be added at both ends of a battery of known frequency and amplitude of the AC voltage signal measured with voltage-phase AC current value, its AC voltage and AC current component of the ratio shall be the battery internal resistance.
Benefits: test method is simple and will not affect the battery's working state, it will not have security implications.
Disadvantages: 1, there are vulnerable charger ripple current and other noise sources interfere with the problem.
2, some equipment can not online (connect the charger and load, and in a floating state) on the dell gd761 Battery to be tested.
3, using the frequency of 60Hz or 50Hz AC test current is more desirable, because it is the charger ripple and noise sources, the main frequency.
