Just Do IT…

Elimination of memory on a regular basis: the laptop battery because of the memory effect, it must be the elimination of memory on a regular basis. The battery is fully discharged and then re-filled. Electrical discharge can be put to use or discharge of the functions of charger also can use the cell phone back-up stand-by mode. If you can speed up the discharge display and lighting of the phone keys to open. To ensure that the batteries can be filled in accordance with the instructions manuals to control the time, sufficient to repeat, two or three discharge.

Optional power-saving mode: GSM standard with an advanced feature, that is, most of the phone have a “DTX” non-continuity.

Launch power-saving mode. In order to power, when the owner is not audible when the phone for the time being launched to reduce the power of radio. Experiments prove, DTX power-saving mode can extend talk time of 30-50 percent. In the quiet of the occasion should switch to static, short of ringing telephone. Select button, or turn off the display lighting. To avoid the bitter cold when the battery temperature is too low, or else time will be shortened. 

powerbook battery types: mobile phone batteries are mainly three types: nickel cadmium (Nicd) batteries, nickel metal hydrogen (Nimb) batteries and lithium-ion battery. Nickel-cadmium batteries can be a greater load current for fast charging. The disadvantage is that the battery prone to memory effect; nickel metal hydride batteries, the industry has been referred to as “environmental protection batteries.” It is the cell phone quality, safe and reliable, and is beneficial to the environment of the cell; lithium-ion PowerBook G4 battery  energy storage of high-density, you can reduce the weight of the phone. The disadvantage is that the higher the cost.

Lithium-ion batteries to protect the design of its chip packaging is closely related to the structure, as shown in Figure 1 for the package in the internal lithium-ion batteries to protect the basic structure of the circuit. Under normal circumstances, charge and discharge control of CO-side control of the high potential for DO-side, N-discharge tube FET1 control and charge control in a turn-on control FET2, the circuit can be a work load to the battery discharge, can also be recharged laptop Battery-charging carried out; when the protection circuit is detected anomalies (charge-off, over and over-current discharge), so that the CO or DO low output in order to cut off the charge or discharge circuit to achieve protection.

In order to effectively use or discharge current charge current, FET1 and FET2 use on-resistance of a small power control. Their choice in addition to the principle of resistance is smaller, but also small and closed source and drain breakdown voltage should be able to withstand does not match the charger. In theory, FET1 and FET2 can control N can also be used P pipe. However, due to a single lithium-ion battery protection circuit of low-voltage power supply, in order to reduce the resistance, generally using N control. Figure 1 is a diode FET1 and FET2 parasitic diodes, the existence of the system they have in the state can discharge the battery charge, charge-off in the state can discharge the load.

Lithium-ion batteries to protect the chip applications requiring low current drive, high-precision detection of the characteristics of the other circuits due to the protection of the power supply is the  dell-latitude-d820.html”>Latitude D820 battery voltage, so the battery voltage changes, the protection circuit must be working properly, this article According to the connection as shown in Figure 1, the relationship between the design of a single low-power lithium-ion battery protection chip, the battery voltage can range of 1V-5.5V change.

System Design

Lithium-ion IBM  batteries to protect the basic functions of the chip is the charge-off protection, over-discharge protection and over-current protection, over-current protection include the charge-discharge over-current protection and over-current protection. The following in order to protect the basic functions of the circuit as the starting point, his analysis of the system.

Anomaly detection

Lithium-ion battery protection circuit in order to achieve its basic functions, first of all need to detect anomalies. And the discharge had been charging the PA2522U-1BAS battery voltage detection is carried out partial pressure (sampling), compared with the voltage achieved; for over-current detection and protection of the chip will first of all in the process of charging and discharging current into power in the possession of FET1, FET2 on the Voltage, and then through the VM compared with the voltage, over-current discharge detection voltage is that, over-current charge is a negative voltage detection.

Signal interference filter

Usually in the lithium-ion battery protection circuit in the process of the work will interfere with the signal exists, the jamming signal, there are two main types: for a moment interference, which is the normal signal, in a very short period of time superimposed on a A larger signal. Another for interference fluctuations, which means the signal fluctuations. Figure 2 explains the process in order to charge the two types of interference, VCU for the charge-off voltage detection.

In order to prevent signal interference with the introduction of the protection circuit malfunction arising from the system point of view and adopt appropriate measures to reduce them.

Instant interference in the internal circuit protection circuit to add delay to filter out, that is, when the protection circuit is detected abnormal signals, delayed for some time and then shut down FET1 or FET2. According to the charge-off, over discharge, over-current lithium batteries on the extent of the harm to select a different time delay. In order to better protect the lithium F2019  battery , over-current discharge can be divided into three levels, namely an over-current protection, over-current protection and load-2 short-circuit protection, over-current of a longer delay, had flows more than 2 delay Over-current of a shorter delay, load and short circuit protection without delay immediately. Fluctuations in the interference in the internal circuit protection circuit to be coupled with slow to filter out.

Effective control of charge control tube to close

In the charging process, and FET2 source connected to the VM potential negative side, as a charge to protect the role, it must have been in charge and signal delay between the plus side CO-level conversion circuit, control logic Have a logic signal conversion, so that the CO-side potential is less than or equal to the potential end of the VM, in order to ensure effective FET2 off.

0V battery charge inhibiting function

Lithium-ion battery protection circuit can be carried out on the 0V battery charge, but also the realization of the prohibition on the 0V battery charge, the paper’s design uses the latter, so that the function of the circuit protection against internal short-circuit the battery for charging. When the battery voltage of 0V battery voltage suppression VOINH (typical value of about 1V) or less when, FET2 potential of the gate was fixed for the VM’s potential in order to prohibit the charge. When the battery voltage is equal to or higher than VOINH, can be recharged.

Other features

1) The charge-off in the state to protect the circuits required to prohibit the discharge over-current protection work. Because the batteries have been recharged after the load connected to the case, in the early discharge, the system is still in charge-off, this time bound to a large discharge current, over-current caused by the possibility of a lot; and over-current protection if the work on Turn-off will discharge circuit. In this way, once the batteries have been recharged, it may never be able to use;

2) play-off discharge protection, the protection of over-current protection circuit required to prohibit the charging function. When the battery discharge too, just connect the charger charging, the charge current will be great. At this point the Prohibition of charge over-current protection work, we can make sure the batteries have been recharged after discharge;

3) In order to reduce the charge current flowing through the internal parasitic diodes FET1 time, if a state of discharge have been connected to the charger and charging VM lower than the voltage over-current detection voltage, to lift-off delayed discharge.

First of all, lithium batteries do not have time extraordinary charge to activate, you can not do, there have been charging circuit protection, the plug will be of no avail.

Second, the activation of the lithium laptop battery (charging curve is correct) for the first time in the general use, not to place a long time, or that the frequent charge that is used for some time, a method that is full charge and discharge, after the batteries that can be That is sufficient to use only in use for a long time before the need to re-re-re-charge and discharge fully corrected.

Finally, the lithium battery life mainly in charge and discharge cycles, the cycle is an absolute concept, for example, if you used the last 30% of the electricity, is full of electricity, in the future, they use 70% of the electricity, and full of electricity, the Is just a charge cycle, rather than two, so those who like to make use of rechargeable batteries of the players together, you own it in fact accelerated the end of battery life.

Some of the sources of misunderstanding:

Every time a rechargeable battery exhausted from the age-old from the NICD batteries, nickel-cadmium batteries that have memory effect, if clinging to make electricity, battery with the use of the increase in the number of electricity and has shown less and less of the state .

Later, the NIMH pavilion battery, fact, has no clear memory effect, but still need to complete the charging and discharging to maintain its normal power consumption shows that this is some of Japan to provide nickel-metal hydride charger refresh function of the principle.

Lithium batteries and there was virtually no memory effect, of course, long after the use of charge or curve will be slightly inaccurate, Apple provides a simple ical prompt you from time to time for battery charging and discharging for correction, but do not have a high frequency.

On the activation of the lithium battery factory just need to use a number in order to achieve the best condition, this is true, but the use of more than a dozen hours of the activation is not necessary (and meaningless) is now charging circuits are taken into account User-friendly, full of batteries will automatically cut off the charging circuit, so that you can not sleep at ease, this time could not plug in the power of fact, there is no difference.

Turning to charge more than a dozen hours of habit, or the age-old from the NICD, such as the battery charge mode slow start, as the original battery charging circuit design behind the general in order to maintain the normal temperature of the battery and battery to prevent damage, Use a small charge current slow manner, and this circuit under normal circumstances do not have the power to determine precise function, so users are recommended such a charge 14-16 hours to see, the error is generally in two or three hours If the charge flow is too large, too charge of the F2024A  will cause serious harm.

Later, nimh for now and rechargeable lithium battery of fast circuit, has been a very good power detection, you can use the pulse-fast high-current charge, and also to maintain the battery in the normal temperature range, and to close Full capacity soon, in order to prevent the charge-off, the circuit from the high current pulse is converted to a gradual narrowing of the trickle charge, so that even if the full power detect some deviation, the more close to full power due to the smaller the current, at the last moment Charge current has been close to 0, no damage to the battery, which is why lithium batteries that 80% of the pre-charge 1 hour to complete, and full of the last 20% of the electricity it 4 hours.

Green curve for the battery charge curve, we can see that power (voltage) of the stage before the very rapid rise in the latter stages of a very gentle, corresponding to the charge current is that there is orange.

A similar understanding:

“As such, it is not, the battery is full, continue flying the power cord is no harm!”

This depends on many cases, by and large say definitely no problem with ah!

The book is in fact general with the F2024B  used in the AC plug ah.

However, there is a special case for a period of time the battery will not have lost some of its own electricity, this is not matter whether you win or come packed in the same book, but when the power falls, it is necessary to determine whether the charging circuit for under normal use The electricity, in that it is necessary to charge again, imagine if the place is full of power and time again full, although users do not use the battery, but batteries are in the non-stop for a small amount of the charge and discharge, accumulated over the fact that Battery consumption in sufficient and effective release cycle, so good design will be a good circuit protection, once the end of the charge, the circuit will automatically cut off, since even if no long-term battery power led to the re-fall will not automatically start charging, unless You switch to using the battery mode.

Therefore, the possibility has been flying AC depends on your ability to design, Apple’s book, and so have such protection, even though be it with ease.

Chinese manufacturer of solar cells, “PV Dongying” in Europe to pay the success of the GEM Listing

Among the many companies on the Growth Enterprise Market of the domestic Wangyanyuchuan, some enterprises have been adopted by the European landing Exchange Listing Prospectus realized dream.

In recent days, Chinese solar cell manufacturer China Dongying photovoltaic solar photovoltaic Group Co., Ltd. through the private placement of 5,120,000 euros, in Europe and Exchange Alternext market success of the GEM Listing, corn oil into China, following China Co., Ltd. and real estate-way, Become the third European settlement in the Growth Enterprise Market-listed Chinese companies Alternext, at the same time is the eighth in the New York Stock Exchange pan-European group in the European market listing of Chinese laptop battery  companies.

The company said that overseas listing will help the company raise funds in order to do business coverage from the  ThinkPad R40 battery production of silicon solar panels to the assembly of the module production chain vertical industries.

Founded in 2006, China’s solar energy photovoltaic photovoltaic Dongying Group Co., Ltd. mainly engaged in photovoltaic solar panel module production, installation and integration, the company’s total share capital of 5,094,028 shares, listed on the first day of the opening to 11.80 euros, on August 15 The closing price of 12.35 euros. The company will be “ALCNP” code for the transaction to the closing price of 12.35 euros calculation, the total market value of 62,910,000 euros to achieve.

At present, a total of 52 clean technology companies in the New York Stock Exchange Group, the pan-European market in the European market. 17 of them in the pan-European exchange, 9 in the Pan-European Growth Enterprise Market Exchange Alternext, 26 in Free Market, which could fetch a market value of listed companies reached 40,300,000,000 euros.

China’s solar energy photovoltaic photovoltaic Dongying Group Ltd., the main market in Spain, France, South Korea and other European and Asian countries. Reporters asked about the external economic downturn led to a drop in demand and the risk of policy, Li noted that as the clean energy industry, solar industry mainly depends on government subsidies States, the current trend more evident.

“In the energy-saving industries, the old can not go back to the original laptop battery . Despite the subsidies, like Spain could face the expiration of concern, but we believe that in October the government may introduce new policies to encourage the production of solar energy. The French may have recently passed Solar subsidies. “He said that next year will bring in sales channels, entering the U.S. market. At present, Germany, Spain and the United States are the three solar panels needs of the market.

Li noted that major companies - solar photovoltaic module production capacity of 156 megawatts by the year’s expansion next year to 256 megawatts. The development of economies of scale will also further enrich the product into the fast-growing various types of solar panels and ultra-thin battery plates in the field of manufacturing. Li can be said that this year’s fourth quarter next year, the company will be the introduction of solar cells and silicon chip production lines, such as cutting, and will improve all aspects of production and improve profits, and promote photovoltaic power generation company in the city’s rapid growth in Linear Technology Corporation (Linear Technology Corporation) to launch a high degree of integration of multiple  F2299A battery monitor IC LTC6802, measuring up to 12 separate cells. The device’s proprietary design to be able to make up more than LTC6802 series (optocoupler or without the use of optical isolator) in order to achieve long strings of access in each cell of the battery voltage monitoring precision. A long string of batteries to achieve high-power rechargeable and applications, such as: electric cars, hybrid cars, scooter, motorcycles, golf carts, wheelchairs, boats, forklifts, robots, portable medical equipment and non - Intermittent power supply (UPS) system.

With excellent energy density, lithium-ion battery as the energy of choice for these applications. However, the design of a large-scale, high reliability and use of time lasting lithium-ion battery pack is a very complicated issue. Lithium-ion batteries for over-charging or excessive discharge very sensitive, and therefore necessary for the battery pack in each cell to carry out prudent management. Since the LTC6208 to each of the  F3172A battery voltage for rapid and accurate measurement (even if the battery voltage 1000V over the case is no exception), to achieve the above objectives.

The maximum gross error in the -40 ° C to 85 ° C temperature range to ensure that less than 0.25 percent, and battery pack in each of the battery voltage can be measured in 13ms to complete. On each battery were carried out over-voltage and under-voltage monitor conditions and provide an associated MOSFET switch, rechargeable Dell battery   have been used to conduct discharge.

From the notebook of the birth of the day, the battery on the controversy has never stopped, because of persistent use of laptops is a very important indicator of technology, and the capacity of the battery determines that laptop’s important indicator. In the end how can we maximize the use of the laptop battery to play the effect of extending the battery life of it? Now, we all set out for a few people often vulnerable to the misunderstanding: (without all that for now the most commonly used lithium-ion battery)
I, for the first time the use of batteries, three times before the need to charge 12 hours?
This is totally unnecessary. Because the laptop has improved power management circuits and charging management system, when the battery reached saturation, the control circuit will automatically switch to the open state, so long as the line is full, does not mean that you will be able to charge more for a long time with longer The.
Second, in order to prevent the memory effect, should it run out of electric charge it?
Every time charge of battery discharge before it is not necessary, but also harmful. Practice has proved that as: the depth of the battery will discharge unnecessary to shorten battery life, when the proposal to use about 10% of the battery can be recharged when the. When the battery, of course, there are still more than 30% of electricity when it would be better not to charge, because the memory effect is real.
Third, insert AC, the battery should be to win in order to prevent repeated charge and discharge it?
I suggest that is: do not have to! Of course, you can get lithium-ion hp battery discharge natural to refute me, saying that in the natural discharge the battery, if there is access to power will be repeated charge-discharge, reduced battery life. I give you a “no” answer to the following reasons:
1. Notebooks now have the power control circuit design of the features: When the battery is 90% (as most of the HP models) or 95% of the charge will be, and to achieve this through the natural discharge capacity of 2 hours a week , When the batteries do not have to idle for about a month to complete in order to maintain the battery charge and discharge capacity at this time you should be concerned about the battery should be about training the body and not be left idle after the re-charging.
2. Even if the battery “unfortunate” was once again charge, the loss will not be brought about by the long period of time than the battery consumption caused by the large decline in the number.
3. Your data than you or your notebook batteries are much more valuable, not only power all of a sudden you have a notebook injury, is unable to restore the data it is too late to regret the.
Fourth, long-term need to preserve Pavilion DV4000 battery  power is full of it?
Read the following table on this clear: (percentage of saturation at the time of the initial value of the relative percentage)
Storage temperature of 40% of the state-of-charge 100% state of charge
0 degrees 98% (after one year) 94% (after one year)
25 degree 96% (after one year) 80% (after one year)
40 degrees 85% (after one year) 65% (after one year)
60 degrees 75% (after one year) 60% (3 months)
It is clear that if the long-term preservation of the battery, as far as possible on the dry and low temperature environment so that the remaining battery power in about 40% of the best. Of course, the best month we should come out with a battery, the battery can ensure a good state of preservation, and not let the loss of full electricity and cell damage.
Fifth, as far as possible in how to use the notebook to extend the use of time?
1. To reduce the brightness of the screen. However, large-screen LCD power consumption, reduce the brightness can be used to extend the time.
2. PowerPlay and open SpeedStep power-saving features, and so on. Now the notebook and display processor chips have a lower frequency and voltage to extend the use of the function of the time, open the corresponding options can significantly extend the Presario V2000 battery life.
3. The use of hard disk drive and the deceleration of the software: NERO DriveSpeed, PowerBooster software can reduce the drive, hard disk drives, such as speed, can effectively reduce the notebook.

If users want to prolong the battery’s effective use of time, apart from the need to ensure the quality of the charger, charging the right skills is also essential, because the poor quality of the charger or charging the wrong methods will have an impact on laptop battery life and the life cycle The following is the author sorting out the charge related to skills:
     1. Battery factory, manufacturers have been activated to deal with, and the pre-charging, the batteries have more than electricity, a friend of mine said that the battery in accordance with the adjustment period recharged, the standby is still a serious shortage of the assumption that the battery had to be really authentic, then the battery, in which case Adjustment period should be extended for a further 3 to 5 times full charge and discharge.
     2. If you buy a new cell phone battery is a lithium-ion, 3 to 5 times before the charge commonly referred to as an adjustment period, more than 14 hours should be sufficient to ensure the full activation of the lithium-ion activity. Lithium-ion battery memory effect did not, but there is a strong inert, should be fully activated in order to guarantee the future be able to use to achieve the best performance.
     3. Some automated intelligent rapid charger when the lights change direction, said only 90 percent full. Charger will automatically slow to change with full battery charge will be. After the battery will be full of the best, otherwise they will be used to shorten the time.
     4. Charging, lithium batteries do not need special discharge, discharge improper battery will be damaged. When charging as much as possible in order to slow Chong Chongdian to reduce the fast charge mode; time not more than 24 hours. After three to five times the hp battery fully charge and discharge cycles of its internal chemicals will be all the “activation” to achieve the best results.
     5. Please use the original or the reputation of a good brand of chargers, lithium batteries use lithium battery charger dedicated, and follow the instructions that would otherwise damage the battery or even dangerous.
     6. There are a lot of users are often in charge when the phone open, in fact, it will hurt the mobile phone is easy life, because in charge of the process, the cell phone circuit boards will be hot at this time if there are external phone, you may have a moment Current back on cell phone parts in-house damage.
     7. The battery life determined by the number of repeated charge-discharge, so to avoid battery power than when the charge, which will shorten the battery life. Phone off for more than 7 days, the first mobile phone batteries should be fully discharged, adequate electricity and then use.
     8. Phone battery self-discharge exist, not when Ni-MH battery will be a day of surplus capacity by about 1% of the discharge, lithium batteries a day by 0.2% to 0.3% discharge. In the Business Notebook nc6000 battery  to charge, try to use a dedicated outlet, and the Chargers do not share household electrical appliances such as TV outlet.
     9. Although the mobile phone network coverage in the region, but in the mobile phone charger off when the phone is no longer acceptable and the call. At this point, you can use the phone did not pass the transfer of functions will be transferred to the mobile phone side of the fixed-line, to prevent the loss of calls, this method is not for the mobile phone network coverage area or a weak signal and being unable to get through when applicable.
     10. Do not expose the battery at a high temperature or cold, like a dog day weather, should not be on the phone in the car, stood in the scorching sun exposure; or get air-conditioned rooms, air-conditioning on the direct blow. When charging, the battery a little heat is normal, but it can not be Jinshou high temperature “suffering.” In order to avoid this from happening, it is best at room temperature for charging, and not to cover anything on the phone.
     11. Nickel-cadmium (N iCd) before the battery must ensure that the battery completely dead, after the rechargeable batteries need to ensure adequate electricity.
     12. If the cell phone not to place too long, to the best cell phone battery to the maintenance department to apply for a living to deal with, you can own a constant voltage direct current, voltage adjustment for the 5 ~ 6V, current 500 ~ 600mA reverse battery connector . Note that the liberalization of touch, up to be repeated three times, after such treatment, re-use original charger “adjustment” charge.
     13. The longer the time when the charge is not good, not for the protection of the circuit full battery charge should be stopped immediately, otherwise the EVO N400c battery  overheating due to heat or impact on performance.
     14. Lithium-ion battery charger must be selected precincts, or may fail to saturation, the impact on its performance. After the charge, should be avoided to place the charger in more than 12 hours over a long time so that the batteries do not have to be separated from mobile phones and want to buy mobile phones must come and see! .

Motherboard battery failure

The laptop battery is dead motherboard cause of computer failure can not be started, see dell battery.

A telephone rings, I awakened from a dream that a friend’s computer problem: press the power button, the computer and nothing happens repeatedly press the power switch is still invalid. After my initial analysis, is likely to be part of the problem of power is not enough power (power of low-grade “patent”) is a short-circuit switch, Collect a variety of tools for a pretty good idea after a friend went straight home.

Indeed, such as friends above, no matter how pressing the power switch (socket and verify that there is good access to electricity), the computer just like wood, like the “one drop of a hat.” Computer does not have any alarm sound, the motherboard does not seem to load the required voltage, power supply fan is not moving, it appears that the computer simply will not be able to power up. Open the chassis closer look at the motherboard and power supply connections and there is nothing abnormal, the power switch is also not short-circuit signs readily connect to other parts again still boot failure.

As the power of “suspects” the greatest, I have decided to replace the method used to verify, just-on-hand to have a 250W power supply, installed after the computer is still “silent”; Is this 250W power supply is Li dell latitude d520 battery, dell latitude d600 battery, dell latitude d610 battery? At this time I noted the chassis installed in the four IDE devices: two hard drives and two CD-ROM. Friends said that just to upgrade, it appears that is likely to be caused by excessive power supply, two of which I immediately unplug the power plug of equipment, try to boot, the computer has not the slightest reaction.

While I am prepared to give up when suddenly the computer’s power supply fan spinning up, then heard the sound of the hard drive self-test, the display is also slowly changing light, the computer launched! But soon, start interrupting, showing “CMOS Load Failure”, and prompted by the “F2″ key to start, according to “Del” to enter the BIOS settings, no matter, I press the F2 key to enable the system to continue to guide, but in any case can not enter the Windows XP desktop, had to restart. The press “Del” key to enter the BIOS settings, friends trying to enter a password, but directly to the, and found the time to view positioned at 0:00 on January 1, 1999, and it is clear the CMOS gd761, td347, dell inspiron 6400 battery is dead . Immediately bought a new battery into one, and all equipment connected to the boot again, the smooth startup of the computer, but still showed “CMOS Load Failure”, had no choice but to enter the BIOS settings to choose “Load BIOS SAFE DEFAULTS” and restart the smooth into the Windows XP desktop, and all the restoration unabated. In the thought that the problem has been resolved, the friends suddenly find missing floppy drive icon, the system did not identify the floppy! Is just now beginning to think that the song might touch the floppy drive connection, so no choice but to open the case more thin, but still can not see the boot floppy. Calm down, just recall the operation “Load BIOS SAFE DEFAULTS”, the floppy drive is set to the default “None”, and restart to enter the BIOS settings, was to prove my idea to come back immediately, with a floppy drive while .

Recalling the whole process, everything is small CMOS battery to blame, it seems that analysis can not be in accordance with the experience of walking, but should be adaptable, to deal with the specific environment; as to why no power CMOS, the computer can start suddenly, Although my analysis may be connected to power after the computer does not start, but the power supply has power to the motherboard, the motherboard CMOS battery to be sufficient dell inspiron e1505 battery, dell inspiron 6400 battery power to start the computer, they have taken place in front of the scene.

Nickel traditional phone if the laptop battery charge time is too long, nickel batteries in the liquid crystal would be to stop the Chargers will be full of electricity. As a result, in order to maximize its performance must be full of electrical discharge or on a regular basis. As for the lithium power, we can at any time at a convenient time for the lithium-ion rechargeable battery, do not need as troublesome as nickel batteries. On the life of lithium power circulating around town: lithium power can only charge at 300-500, followed by the need to be replaced.

The right to say: rechargeable lithium power and life cycle concerned the number of completed, and not directly related to the number of charge. A battery charge cycle means that all the electricity used by the space age, and then by air to a full charge. This is not a necessary and sufficient electricity.

40% of the first charge, after a period of time charge of 20%, used the next time after filling 30%, 20 %….. in the next 20% of the way, that is, just add 10% Electricity, the cumulative total to complete a charge cycle. Followed by the next cycle.

Simple to understand, for example, a lithium power in the first day only half of the electricity and then it was full of electricity. If this is also the second day, that is, with half of the charge on a total of two charge down, this can only be counted as one charge cycle, rather than two. As a result, may often go through several times to complete a charge cycle. Each to complete a charge cycle, the capacity will be less. However, the rate of reduction is very small, high-quality inspiron battery charge cycle many times, will still retain the original 80% of the electricity, a lot of lithium-powered electric products after 2023 as usual after use, is for this reason. Of course, life lithium power to end the need to be replaced.

Lithium battery life is generally a 300-500 charge cycles. Assuming a full discharge of electricity provided for the Q, if not to consider each charge cycle after the reduction in electricity consumption, the power of lithium in its internal life or to provide a total of 300Q-500Q to add to its power. From this we know that if each with 1 / 2 on the charge, you can charge at 600-1000; if each with 1 / 3 on the charge, you can charge at 900-1500. And so on, if the random charging, the indefinite number of times. In short, no matter how necessary and sufficient, to add a total of 300Q-500Q into electricity that is a constant. Therefore, we can also understand this: The iBook G4 battery  life of lithium batteries and the charging of the total electricity consumption, and the number of unrelated charge. Take deep and shallow depth charge put sufficient light for the life of lithium power more or less the same.

In fact, the simple release sufficient light for the benefits of more power lithium-only products in the electric power module for the lithium to do calibration, the only deep deep release the necessary and sufficient. Therefore, the use of lithium-powered electric products do not have to rigidly adhere to the process, all to facilitate the first, charging at any time, without fear of impact on life expectancy.

Temperature not too high

If the requirement is higher than the operating temperature, that is, more than 35 ° C environment, the use of lithium batteries, battery power consumption will continue to decrease, that is, the battery power supply will not be as long as usual. If such a temperature, but also for the charging device, the battery will be a greater injury. Even in a hot environment, storage batteries, the batteries will be inevitable for the quality of the resulting damage. So, as far as possible to maintain the proper operating temperature is beneficial to extend the power of lithium a good way of life.

Not too good

Li Xinhua, also found the same battery life by reducing some of the phone Yuanzhuanglidian in low-temperature environment is not even necessary and sufficient electricity. However, do not have to worry too much, this is a temporary situation, is different from the use of high-temperature environment, once the temperature rise, the Inspiron 8000 battery  of heating elements, immediately prior to the resumption of electricity. Movement is life

To play the largest lithium-ion battery performance, and often need to use it, so that the power lithium-e-Status always flow. If you do not often use the power of lithium, be sure to remember a month to complete a rechargeable lithium power cycle, so a power calibration, that is, filling a deep deep release.
We must pay attention to the maintenance of cell phone batteries

Kyocera announced that it would increase the production of solar cells. The company in April 2007 issued a plan for the year 2010 will be in production as a battery of 500MW, this is not only to increase that figure to 550MW, is also planning to the year 2011 to increase production 650MW. Investment, over the next 4 years to reach 55,000,000,000 yen. In addition, the company’s 2008 annual production plans for 300MW.

The reason why the year 2010 will be the year of production from the first 500MW to 550MW, due to “the production process to improve the efficiency of the outcome,” (Kyocera). The company engaged in a wide range from ingot manufacturing to module manufacturing business, through various processes to increase productivity so that the annual output increase of 50MW. Increase to 650MW, is the view of the silicon raw material procurement, and so on have already been implemented to make the decision-making.
