Reduce the power supply output voltage 0.5V is not an easy thing, series resistance does not work, because the resistance of the voltage will change with the current size. I use silicon rectifier diodes, to allow more than through the current in the 2A, or hot tube. Silicon Rectifier diode forward voltage drop between 0.7 to 0.5V, just to meet the requirements. Now a plenty of such tubes in the electronics market, price less than 2 yuan. To a different book on the specific situation may be different, the best time to install a digital multimeter Cece hand. Pipe is being connected serially in the power output, and still harder to buy a power plug inserted himself in the notebook. Diode which is not reversed, the book does not work it wants, and then in turn connected on it.

In this way, the power output voltage drop is about 0.5V, if the drop too much, the book will switch to battery, if the drop too low, the book will charge the battery, the specific number to you in your own notebook tried to know.

Of course, if your battery is full, this circuit is not necessary, you can not have it connected directly to the power output can be had on the books.

This point, the two issues mentioned at the beginning resolved. It is up to you test results, and estimated book on different results may be different, it is best to first try to take a circuit, so that took 10 innocent money

Finally I wish you good luck! Good use of your Lithium now!

Special Reminder: HITACHI Camcorder Battery PANASONIC Camcorder Battery

In the modified plug when the mistake is most likely to engage in anti-polar (diodes engage in anti-polarity does not matter), so you must double-check, measured with a multimeter, with different colors of wires to connect the positive and negative. I do not know engage in anti-polarity power supply will not burn the books, did not try!
If all aspects of laptop battery

Mentioned above, the lithium battery, the battery in the end points of several books then? We take a look at the general books batteries into nickel-cadmium batteries, nickel hydrogen batteries, lithium batteries of three. Nickel-chromium batteries, since batteries are bulky, heavy weight, small capacity, short life, there are disadvantages such as memory effect has been abandoned the market. Two kinds of lithium and nickel-hydrogen present to the market mainstream, which lithium is small, light weight, large capacity, low memory effect, charging time and short, is that large businesses use. Lithium has two types, one is lithium, the other is lithium ion battery. Lithium problems such as burning, bursting insecurity, was suspended.

If all aspects of laptop battery

Subsequently, after the improved lithium-ion battery, comply with the safe, efficient, convenient standard, and a market-driven, the time of purchase as long as the Note: Li-ion, the sign on it. The nickel-hydrogen batteries, it can be said is in line with the recent advocacy of environmental topics, and this mainly proud of its recycling features in! But there are also shortcomings, such as the charge time is long, weight, capacity, and small defects than lithium. However, the more charge cycles than lithium-ion battery from 400 to 600 times the mean, Ni-MH battery high record of 1200 is very tempting! In fact, the books also determines the price of the battery price books, if we can know the origin of the battery case, price is favorable for the Hom! Japan, Korea, China and Taiwan have produced books in the battery SAMSUNG Camcorder Battery TOSHIBA Camcorder Battery, especially Japan, mostly alone in Taiwan Province on the price of the battery is relatively cheap, the quality of Japan, South Korea is better! Capacity, the unit is mA / pm, recorded as: mAh, mA / time when the leading books of life, of course, the larger the number the better! 4000mah can support 4 hours of flying time, and with long life time known Matsushita Electric, has more than 4500mah battery capacity, should pay more attention to buy!

I often see the discussion of articles for books battery energy, say are some skills, but this is the books like to discuss every aspect of the battery, if the look and make you feel half the experts, then even if an end of the article!

First to look at books from the perspective of saving the battery, as to energy conservation, it is necessary to first know how to avoid cell “aging”! Typically, the battery internal resistance with the use of time as the growth becomes larger and larger, there will be voltage drop mate, system voltage support is not sufficient, resulting in severe shortage of electricity. Over time this will be a vicious circle, seriously affect the battery life books. This was lucky, sometimes your books battery failure will be a failure in a very short period of time, it is a headache! This failure is probably caused by batteries, this mostly occurred in the lithium battery, who are just like the books of the battery flashlight stabbed home as is a composition of one of the batteries, as long as one of a failure, then it will result in the overall series, voltage delay, regarding the scrap it! Therefore, to use electricity during charging, do not use industrial power, as voltage is too large, will affect the discharge curve! Start charging, do not select the fast mode (BIOS setting), battery charging with constant current charging mode, the system load current, avoid the CPU, hard drive, LCD power struggle between the phenomenon. Discharge when the deceleration let CPU, hard disk stops and the screen transferred to the darkest (or closed off), do not run any programs until the laptop automatically shut down to achieve the objective of low current discharge. Also, if you can find in the market, “temperature protection device”, then the best of! It can be achieved by adjusting the overall balance, very good battery backup protection devices TOSHIBA Laptop Battery ACER Laptop Battery.

Now more and more people use the notebook as a notebook lithium batteries, one of the main parts of the problems also increases. So how good use of the notebook lithium batteries do? Grasp the main points:

1. To the appropriate charge and discharge current.

2. To minimize the discharge less than the charging or over-discharge.

While the battery is a consumable, lithium-ion battery is no exception. But no one wants to use up the battery fine spirit of God, to what age do not even rattle is finished, no one wants to start his own half dead battery does not pull the living, has been rubbing on it in 2023, makes good sad to realize how the thing about you is not?

Well, get down to business, following the battery began to speak. First explain, only lithium-ion battery HP Laptop Battery.

Appropriate charge and discharge current

General literature and the state standard on lithium-ion batteries on said lithium-ion battery charge current should be between 0.2C to 1C. It is said that the charge current battery capacity, such as your battery is 4AH, then the 0.2C charge current is 0.2X4 = 0.8A, that is the charge current should be between 0.8 to 4A. In general, the charge current at the extent permitted by the smaller the better, rechargeable lithium-ion battery should be a constant current charging the start, in my IBM R31, this current is about 2.8A, equivalent to 0.7C, is charging its own circuit control can not set yourself. Although this indicator does not charge more than the standard requirement, but is actually relatively large, especially when the battery capacity decline for some time after the charge current may be more than 1C. Now the length of time charge notebook users have also become targets regardless of the manufacturers were forced to set such a high charge current.

So first step is to reduce the charge current. I have a friend in the lab, all equipment readily available, on trial with him a bit. Power outlet on the first series resistance try a result, current is reduced, but became intermittent charge, this is not a good thing. Through trial and error, 4 Ohm is a more ideal value, this time around 0.8A charge current is very stable. This is only the current flowing through the machine power connector, battery charge current is estimated to larger, should be slightly larger than 0.2C. Specific to a different machine, this value may be different. Also with the increase in battery voltage, charge current will be reduced, but the decrease rate is small, less than 0.05A. In this charge state, charging circuit seems to not work, the battery indicator light is not bright. Etc. After the battery voltage up to 12.6V, charging circuits came into play and trickle charge the battery into the state, this time does not matter whether the series resistance has been, the charge current is controlled by the charging circuit, the last full charge after the charging circuit automatically end. The charging time is about 5.5 hours, if not resistance, charging time is 3.5 hours or so.

Lithium ion batteries are very delicate, good charge control circuit is required. With this charging method, can reduce the charge current, battery life, while use of the books original charging circuit controls the charge is relatively simple to achieve them, just buy a power plug (that is, from the power supply plug into the notebook kind, the best to buy two, followed by the methods referred to still use one, be of good quality) and a resistor on it, pay attention to big head and little resistance, after all the above are about 2W of power Otherwise, it would be more heat resistance, preferably constant resistance of the wire myself one of the wire resistance and this resistance is independent of temperature. However, this disadvantage is also obvious that, while not charging work with books. In addition, when charging will have a strange phenomenon, I do not write omitted here, and you try to know, Fortunately, this phenomenon into the trickle charge after the state disappeared. To extend the charging time is not a big problem, anyway, before the night began to charge the next day wake up and fully charged, of course, if you are a night owl or a special short sleep time, that is another matter.

Small current charging problem solved, and now discharge problem. In fact, this is difficult, after all, the book is used to work, the discharge current will vary with the working state, the method mentioned here only designed to restore battery capacity of the operation.

Start the machine, set the power management will never go to sleep (standby) and hibernation (hibernate), others are set to the most power-saving mode, including CPU speed, turn off hard disks, turn off displays, while in TP management process Close some unused hardware, such as sound cards, etc., and then open the battery status display window, and allowed to run in the foreground! ! ! Close other programs, in particular, screen savers and other programs that run on time! ! Do not use the machine, do not close the lid, let the battery discharge end (not to discharge the minimum value set to 0, I set up 3%). Display and hard drive shut down, the discharge current is about 0.5A, this is my IBM R31 can be achieved on the minimum discharge current, battery LG Laptop Battery discharge to the minimum value of the machine will automatically shut down after. The discharge lasted for more than four hours, depending on your battery capacity may be different in different, this time is also used to sleep way to send the.

Well, the last to emphasize that the method is not dead, especially discharge, 10 times which can be done once, or else why should the battery? Charge all the best with a small current charge, of course, if the need to use batteries, power cord plugged directly into the notebook on it.

Using this method my battery is now fully up 14 times, the capacity has been maintained in 45 more, the battery design capacity is 43.2, and has come down, but after such a charge and discharge are restored.

Beginning about two points, one appropriate charge and discharge, and second, not to discharge less than the charge, discharge less than the following to see how to solve the problem on the charge it:

To minimize the discharge less than the charge or over discharge

In fact, over-discharge a good solution, not to terminate the discharge limits set too low on it, I have been using 3%  LENOVO Laptop Battery.

Often use batteries may only be a short Shi Jian, such as battery remaining 70%, if the switching power supply, then the battery will Zidong charge, such a loop vanishes, although the battery’s Shoumingbushi set to cycle the absolute number of death of, but always it will reduce the battery capacity, lithium-ion batteries have no memory effect reported, but in fact only a relatively low Bale memory effect. Unfortunately, IBM does not provide solutions to discharge less than the charging method, but provides the basis to solve this problem. This is what I found on the R31 may not be suitable for other machines, but the method should also not far off, do not forget after you’ve tried were posted for all to share.

R31 charging circuit based on the status of the power to decide whether to charge the battery. Power supply output voltage is 16V, within error of plus or minus 0.2V, if the voltage is lower than 15.5V, so not to charge the battery charging circuit, and books can also work, this is the IBM provided the basis for settlement. But the foundation is weak, because the voltage, if less than 15.2V, books will be converted to battery power, even if the power outlet in the books are useless. In other words, we can torment the space is 0.3V.

If you can find a 15.5V, over current 3A switching power supply, then the problem is solved, otherwise please continue to look down IBM Laptop Battery SONY Laptop Battery.

Reduce the power supply output voltage 0.5V is not an easy thing, series resistance does not work, because the resistance of the voltage will change with the current size. I use silicon rectifier diodes, to allow more than through the current in the 2A, or hot tube. Silicon Rectifier diode forward voltage drop between 0.7 to 0.5V, just to meet the requirements. Now a plenty of such tubes in the electronics market, price less than 2 yuan. To a different book on the specific situation may be different, the best time to install a digital multimeter Cece hand. Pipe is being connected serially in the power output, and still harder to buy a power plug inserted himself in the notebook. Diode which is not reversed, the book does not work it wants, and then in turn connected on it.

In this way, the power output voltage drop is about 0.5V, if the drop too much, the book will switch to battery, if the drop too low, the book will charge the battery, the specific number to you in your own notebook tried to know.

We all know that the battery will not charge if the impact would be very time of their life and the use of, then how can the effectiveness of the right to play their best then? Let me show A thin thin for everyone Tao Road to – a very thin very thin (imagine the echo effect of your own ^ ^)

Some equipped with lithium-ion laptop batteries using the battery system such as SBS intelligence technology to accurately measure the battery life, so use of some peace of mind. Although there are many advantages of lithium-ion batteries, but battery life, the power supply last longer, need to master some professional charge method. Laptop Battery camera camcorder battery TOSHIBA Laptop Battery ACER Laptop Battery
Bought a new lithium-ion batteries used for the first time, the need for 3 full charge and discharge, that battery fully charged at least once a power, then power up to do, repeat three times before use. To activate the chemicals inside the battery, the electrochemical reaction inside the battery into the best in the future can be freely used in the charge that is used, but within a month to ensure the battery must be a complete discharge, so depth of discharge can stimulate cell activation performance, battery life plays a key role. If more than 3 months the battery is not used again until the same should also be carried out with a new battery charge and discharge completely 3 times to ensure that activate the batteryACER travelmate 4600 battery Dell INSPIRON 6000 battery.

The use of nickel-metal hydride batteries, which must control the charge time, should be careful not to over-charge frequently, otherwise it will shorten the battery life. In addition, the NiMH battery be fully discharged before charging, the charging should be fully charged before use and in the normal, also requires the completion of 3 full charge and discharge ACER aspire 5560 battery ACER BATBL50L6 battery.

Most users used each time when using a laptop, plug the AC power supply are very rarely use the battery to the notebook computer power supply. In fact, every month should be at least one or two batteries to power, the battery completely run out, connect the AC full-time. Remember this one, for charging batteries will run out again full of power, useful and harmless, because the notebook computer lithium-ion batteries used in certain inertia effect for a long time without loss of activity of lithium ion would need to re-activation APPLE M8403 battery ACER aspire 3000 battery. When the notebook computer using AC power when the room is best to remove the battery so it often is in charge state. Best off when charging laptop, the battery can be fully charged, do not disconnect the power in the charge halfway. Fully charged, should be used within 30 minutes.

In addition, because the battery is easy to run out of power, most of the notebook computer has only one battery, thus, part of the document so that computer manufacturers developed a fast charge feature that allows users to reduce power consumption and the fastest speed available after the additional power . For example, Dell’s notebook computer will have ExpressCharge feature, you can recharge in one hour more than 90%. Why not 100%? Because according to the charge and discharge characteristics of lithium batteries, if often charged up to 100%, the battery life on the big shortened notice, so 10% will be back before the slow-fast charge to charge to extend battery Dell INSPIRON 6400 Battery Dell INSPIRON 9400 Battery life.

No such function for ordinary laptops, the best way is to charge off, charge off charge will be 30% shorter than the boot over the charging time.

Laptop battery routine maintenance and precautions:
Notebook computer battery a long time, it is often sufficient dissatisfaction and even damage the battery. Therefore, the battery maintenance and restoration needs of laptop users is a topic of concern. Maintenance process is often referred to as “activation”, “activation” to reflect the very image of the battery “dead” and rebirth process. I summed up the way a cell activation, its basic principle is that when the current charging and discharging must be small (but not too small, or too long), there is as much as possible to full, put completely.

Causes of damage the battery
Battery will be used after a period of time “aging” of the. Specific manifestations of resistance become larger, the voltage across the charging time increased quite rapidly, so it is easy to charge control circuit is judged to have full capacity will naturally be “down”. As the larger battery internal resistance, discharge voltage drop, high speed, the system can easily mistaken for a voltage not enough, power is low (in fact there is not power up). As can be seen from the above description of the battery is a vicious cycle of aging process, the discovery of battery time out faster than what it should be tempered, or else will be finished sooner or later TOSHIBA Laptop Battery ACER Laptop Battery.
In addition, many lithium battery failure is the failure of the bag resulting in a saving core, an assumed name or bad a pot of soup. This phenomenon is inevitable, because every energy-saving battery can not be completely consistent with the nature of the core, there are some quality with long aging first weakened and damaged the whole (series) if the discharge curve. It simply means that section of bad batteries before charging full, discharge it first had finished, but this time the capacity of other batteries are not being fully utilized. Core of a saving over charge / over discharge will not cause the battery monitoring circuit that is full / End of release. For example, when charging other batteries began charging close to full pressure of time, that section of bad batteries may have to 4.30V or even higher voltage, resulting in overcharge damage, while others are fully satisfied. Editor’s Note: The internal batteries for battery damage, the “China Computer Education,” 2001 No. 2 has a great article – “laptop battery DIY” worth learning. Interest, courage and ability friends can try to open the battery pack, believe in the multimeter’s help, you can quickly find the damaged batteries

(abnormal voltage). If conditions allow, according to the corresponding parameters of batteries can replace the qualified product.
Battery charge and discharge
Lithium-ion battery charging, first by way of constant current fast charging, the voltage reaches a certain value and then to constant slow charge mode. Usually laptops are not strictly constant current charging control device. When the system load large charge current to a small, contrary to 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. I tried to run side Superπ, while charging the way, found that the charge current between the change in the 0.70 ~ 1.70A, can not meet the requirements of lithium-ion rechargeable battery, so I worry that this work will charge the battery has been damaged. IBM statement on the requirements of the notebook computer will not operate when charging is probably the reason.
Charge at boot time, if we can select the charge mode, do not select the fast charge mode (Express charge mode), to avoid premature battery “full.” There was a time of low battery prohibit the use of the highest performance CPU to reduce power struggle. If the notebook uses the CPU to support SpeedStep technology, it is best to install the driver (responsible manufacturers are installed) to facilitate the adjustment performance. SpeedStep program icon is a blue flags, right-click performance tuning options it can occur. In Windows XP systems, SpeedStep program will be problems, this time to modify the BIOS parameters, or to rely on a number of brand-specific regulatory procedures, such as the IBM notebook computer is very powerful tool.
Lithium has been switched on or discharge, let it discharge better. Is best not to use physical methods (series resistors of the class). This is not to say no, only relatively large risk, if the internal protection circuit not working, then the battery on the void, and the worst is probably the battery explosion, of course, this is unlikely. Circuit hidden danger is not impossible, some big companies have found that the design of the potential risk factors than the battery recall, as when cell phone battery explosions do not hear about the

APPLE Laptop Battery DELL Laptop Battery .
Tips: In general, the protection of laptop battery is a voltage regulator circuit components are usually block, control chips, insurance, and temperature probes. Temperature protection device is usually one-off, the inside has a fuse (fuse some 130 ℃), used to monitor the voltage regulator block work. If the process of abnormal discharge, immediately there is a current through the temperature protection device, the fuse blows, the circuit inside the battery at this time for the off state, and unrecoverable. If you want to repair only the replacement of the temperature protection, but such temperature protector is hard to find in the market.
Discharge is the discharge current as small as possible, the operation is slow down and let the CPU, hard disk stops and the screen tunes are dark (or closed off), then do not run any programs until the laptop automatically shut down. The emphasis on small-current discharge is to prevent the notebook computer battery voltage detected early enough HP Laptop Battery.
I disabled the hard disk, close the screen, cancel the power state of alarm on the laptop completely discharge (up nearly 6 hours), the battery capacity from 31.72Wh restored to 33.65Wh.

It was the laptop battery for the body than blood, although this is not very precise, but this still shows the battery in laptops importance SHARP Camcorder Battery SONY Camcorder Battery .

I bought second-hand notebook computers have been for some time. Beginning with the battery to the notebook computer power supply can persist for 50 minutes, then less and less time to last only 10 minutes of work. Although on second-hand laptop battery is unrealistic to expect too much (as long as several minutes can be used to prevent power failure can result in data loss), generally used only as a UPS. But actually, I always go behind her back, often in areas with no outlet to use her, and therefore always want the battery to work as long as possible, as this can greatly enhance the mobility of notebook computer use HITACHI Camera Battery JVC Camera Battery.

Spent a lot of energy in the market looking for, but failed to find Original battery. Trusted in themselves have some understanding of the battery, and have a certain appliance repair skills, so try to repair themselves. Following operation, the necessary tools (Figure 1): multimeter, soldering iron, tweezers, blades, electric tweezers, tape, electric wire or a small light bulb.

Capacity recovery method EPSON Camera Battery NIKON Camera Battery

Figure 2

To remove the battery from the laptop (see Figure 2) and found the battery case labeled “Ni-Cd”, “9.6V 2000mA” words, indicating that the battery is a nickel-cadmium batteries (rechargeable battery types is one of the worst species), rated voltage of 9.6V, capacity 2000mAh. Battery on a total of eight metal interface, respectively, from left to right mark (the battery with the label side up): – TTI I + +.

Measured with a multimeter showed that the cell has two batteries, the most left “-” and the right side of the second “+” is a group, left the second “-” and the far right of the “+” is a group. Detection of two no-load battery voltage actually have to 9.8V, and then the battery is low voltage alarm start after laptop out of (it is reasonable that there should not be too much electricity!) So guess: Laptop starts automatically after a period of low voltage alarm off, and then the battery is not fully discharged, that is, a certain residual capacity, and nickel-cadmium battery memory effect is not fully discharge the charge, he began will reduce battery capacity.

So get two heating wire (can change with a small light bulb or power resistor) connected to the positive and negative ends of each battery (discharge current 200mA ~ 500mA can be controlled between the concrete should be determined depending on the capacity of the battery – General to 0.2C ~ 0.5C, that is the PANASONIC Camera Battery SAMSUNG Camera Battery battery rated capacity of 0.2 to 0.5 ratio of the current discharge), the battery is basically done and then use the multimeter to 10A current file to call completely exhausted, and finally put the battery Back to the notebook computer for normal charging. Repeat this four times and found the battery has been able to work more than 40 minutes of time, basically to meet the requirements.

If your laptop battery is also a similar situation, according to the method a try, perhaps there will be an unexpected result! In addition, if your laptop uses a lithium battery, the battery discharge must skip the battery chamber of the circuit board, because the only way of achieving good results. Replace the battery core

Capacity recovery method with only a battery using the time to solve this problem, in addition to replacing the battery outside the (second-hand laptop battery is very hard to find the same model), we can change the battery core. But it needs more battery knowledge you know, have more operational skills. Still below the battery of my laptop case (laptop model is the Fujitsu FMV-575NU / Y), introduced the replacement of the battery core

Although the laptop battery at the same time within the two sets of batteries to power the machine, but testing with a multimeter notebook battery compartment spring contact piece and found the battery marked “+” or “-” the metal in contact with the two spring contact piece is connected, that is in fact the two groups in parallel with the battery power supply to the machine.

With a razor blade slits along the side of the battery carefully cut open the battery and found boxes of 16 single cells (Figure 3), which can be converted from single-cell voltage and capacity were: 1.2V, 1000mA. Although its shape and size and the general 5, the same nickel-cadmium batteries, but with the capacity of the battery can not find in the market. Finally, a second-hand computer store to find a Fujitsu FMV-575NS / L laptop battery (Figure 4), the label can be seen from the shell of the battery is lithium ion battery (Li-ion), voltage of 10.8V, capacity is 2400mA . And although my laptop is Fujitsu, but the voltage, capacity, and battery properties and have some discrepancies, could replace the heart has no bottom, but still spent 180 yuan bought.

tied into a whole and placed within a notebook PC battery compartment (Figure 6). From the notebook computer battery compartment in the two and the “+” contact spring connected to an arbitrary choice of the film, with a wire to the positive terminal of the battery connected to it; also choose a “-” connecting the spring contact pad and battery connected to the negative. Finally, also within the original battery connected to the two marked “T” word on the interface of a metal piece of electronic components (see Figure 3 part of the circle, this component is estimated notebook battery identification circuit part, with to detect whether the battery has been connected to the laptop computer) remove, welding position in notebook computers within the corresponding spring contact chip (if not the components, batteries for laptop power supply, the Power On Self Test will appear after some time the machine automatically power of the phenomenon). Of course, these operations should be carried out in the off state. The use of effect after the reform, it should be said to be very satisfactory: I just bought a laptop, the battery can work over 50 minutes, after the use of such methods scrapped restructuring, the experiment found that cells can escape from the work of 2 hours and 40 consecutive minutes, which greatly surprised me. Although this example is in my Fujitsu laptop the successful SAMSUNG Camcorder Battery TOSHIBA Camcorder Battery experience obtained after the experiment, but we can actual analogy. It should be noted that the restructuring should take into account several key parameters are: the battery voltage, rated capacity and size. Voltage and rated capacity is slightly different, no problem; but if the battery after the reform are too large will not fit the original battery compartment, no matter how long the battery-powered, are not meaningful (you will never be the battery on the outside of notebooks, with a long trunk and a few wires pulling it – if this is the case, portable laptop computers are crippled up HITACHI Camcorder Battery PANASONIC Camcorder Battery!)

We love machine maintenance lithium how should be right? This problem has plagued many loyal laptop users, including me. Access to some information in the following, recently had the opportunity to consult a professional in the electrochemical PhD and a well-known domestic battery, deputy director of the Institute. Now get some of the most recent knowledge and experience in writing, to satisfy the readers of you. CANON Camcorder Battery JVC Camcorder Battery

The cathode material for lithium ion battery lithium-active compounds are usually formed, the negative is a special molecular structure of carbon. Common cathode material mainly composed of LiCoO2, charging, plus the electric potential in the battery poles to force release of positive ion compounds, embedded negative elements arranged in lamellar structure of carbon. Discharge, the lithium-ion from the lamellar structure of the carbon in precipitation, and positive re-combination of compounds. Lithium-ion mobile rise to a HITACHI Camcorder Battery PANASONIC Camcorder Battery current.

Although the chemical reaction principle is very simple, but in the actual industrial production, the practical problems need to be considered much more: cathode material additives required to maintain the activity of several charge and discharge, anode material required to design the molecular structure level accommodate more lithium-ion; fill in the electrolyte between the positive and negative, in addition to stability, but also has good electrical conductivity and reduce the battery internal resistance.

Change the shape of a variety of laptop battery

Although the lithium-ion batteries are nickel-cadmium batteries little memory effect, memory effect is the principle of crystallization in lithium battery, almost not produce this reaction. However, the lithium-ion battery capacity after repeated charge and discharge will continue to decline, its causes are complex and diverse. Mainly SAMSUNG Camcorder Battery TOSHIBA Camcorder Batterypositive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ion on the hole to accommodate the structure will gradually collapse, blocking; from a chemical point of view, is the active anode material is passive, there’s the other side to form a stable compounds. Cathode material physics will appear gradually falling off, etc. In short, can ultimately reduce the battery charge and discharge process of free movement in the lithium-ion number.

Over-charging and over-discharge, lithium-ion batteries will cause permanent damage to positive and negative, from the molecular level, intuitive understanding, excessive discharge of carbon anode will lead to excessive release of lithium ion and makes it appear lamellar structure collapsed, over- will charge too much into the negative electrode of lithium ion hard carbon structure to go, and make some lithium-ion can no longer be released. This is also why the lithium-ion batteries are usually equipped with charge-discharge control circuit reasons.

Not suitable for the temperature, will lead to an internal lithium-ion batteries produce other chemical reactions of compounds that we do not want to see, so many of the lithium ion battery between the positive and negative temperature with protective membrane or electrolyte additives. The battery temperature to a certain case, the composite membrane electrolyte membrane hole closed or degeneration, increased battery internal resistance until the circuit the battery Laptop Battery camera camcorder battery TOSHIBA Laptop Battery ACER Laptop Battery will not heat up, to ensure the battery temperature is normal.

The deep charge and discharge lithium-ion battery can improve the actual capacity? Experts clearly told me that this is meaningless. They even said that the so-called three full charge up before using the “activation” in their knowledge of where the two doctors, also need to figure out what this. But why so many people of deep charge and discharge capacity after the Battery Information will change in labeling it? Will be mentioned later.

Notebook 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 is in use will gradually change. Personally, I think, in notebook 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.

Main control chip, battery charge control the 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 voltage phase, the voltage will not increase to ensure that no over charge and current increases gradually as the battery weakened to 0, and the final charge.

Statistics chip power consumption records through the discharge curve (voltage, current, time) can calculate the sample battery, that is what we read about in the Battery Information wh. Value. The lithium-ion batteries used in many post-discharge curve will change, if the chip has been no opportunity to once again read out a complete discharge curve, the calculated power is not accurate. So we need to calibrate the battery charge and discharge of deep chips.

Finally my battery maintenance view is:

1. No need to ensure the release is finished each time a re-charge;

2. A period of time can do under the control of a protection circuit to correct the deep charge battery discharge statistics, but it will not improve your battery’s actual capacity.

3. A long time without the battery, to be placed in a cool place to weaken its own internal passive reaction speed.

4. The protection circuit is also able to monitor the battery self-discharge, long-term without the battery, should be pumped into the power to prevent the battery self-discharge in storage in the discharge of excessive lead to excessive LG Laptop Battery LENOVO Laptop Battery damage.

In fact, the battery is not too much to take into account the use of attention, in other words is taken into account is not much use. How many times a cell can use, perhaps more from differences in the manufacture of the battery itself, the individual differences, rather than use. Select has a good reputation in the notebook PC brand, is undoubtedly the future protection of battery life is one long.

Electricity charge and avoid exhaustion after the long charging time Dell INSPIRON e1505 battery Dell INSPIRON 2500 battery IBM Laptop Battery SONY Laptop Battery

Regardless of your notebook to use nickel-metal hydride or lithium electricity, to power must be exhausted after the full (capacity less than 1%), which is the best way to avoid the memory effect. No memory effect on lithium argument, I explain in Part Two is a business irresponsible been misled. Lithium also have memory effect, but it is the memory effect than Ni-MH small number of Bale. And battery charging in the same way, when you charge the battery to the laptop, try to avoid too long, the general control within 12 hours.

As for the prevention of exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the battery contacts and metal objects such as attention, radium also little mention here.

Fifth, protect the battery, notebook manufacturers What coup?

I understand that many laptop vendors are now taking into account the vulnerability of the battery, and battery products added protection technologies such as: IBM, HP, Toshiba, Compaq, etc.. Consider the most thoughtful of them is IBM, IBM laptop battery discharge condition can be detected until the power off until after less than 2% charge. This can play a very good protective effect on cells, but also for other companies learn from.
