The rechargeable lithium batteries in the right ways

Friday, October 24th, 2008

Earthen jar in the past seen a lot of clearance with the charge that there is on the wrong … I have been misled … now to find a comparison
Professional, and hope that we have read to understand. I am on the phone earlier version, but if you do not see that, in turn on the

In the use of lithium batteries should be noted that for a period of time after the sony-DP390A-charger.htm”>hp DP390A battery is placed into hibernation, lower than normal capacity at this time, the time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycle of the battery can be activated, the resumption of normal capacity.

As the battery lithium own characteristics, its decision is almost no memory effect. Therefore, cell phone users in a new lithium battery in the activation process does not require special methods and equipment. Not only is the theory that, from my own practice, from the very beginning, the use of standard methods of charging that “activation” is the best way.

Lithium batteries for the “activation”, a large number of claims: the time to charge more than 12 hours, repeated three times to do in order to activate the battery. “The first three necessary and sufficient to charge more than 12 hours”, it is obvious from the nickel hp 346970-001 battery (such as nickel-cadmium and nickel metal hydride) inherited. This is why it can be said is the beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics of a very big difference, but also very clear to tell you that I have had access to all the serious official stressed that all technical information and charge-off will discharge lithium batteries, especially lithium liquid Ion battery causing great harm. According to the charge and therefore the best time and method of charging standards, in particular for not more than 12 hours of super-long charge. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of charging.

In addition, the lithium battery in the phone or battery charger will automatically stop after a charge, there is no electricity nickel charger for 10 hours the so-called “trickle” charge. In other words, if your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one battery charge and discharge protection circuit features and never change the quality of safety, so your batteries will be in the long-term hovering on the brink of danger. This is also another charge against the chief reason.

In addition to certain mobile phones, the charge for more than a certain amount of time, if not remove the charger, this time not only to stop charging system, will be the beginning of discharge - charge cycle. This is perhaps the manufacturer has its own purpose, it is clear that on the phone and hp HSTNN-UB02 battery  / charger is the life span of a negative. At the same time, long charging would take a long time, often at night, and to our country’s power grid situation, at night in many parts of the relatively high voltage, but also volatile. Said earlier, the lithium battery is very delicate than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this brings additional risk.

In addition, can not be ignored other aspects of a lithium battery that is not the same for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following question.

2, in normal use when the charge should be

In our forums, often see this as the number of charging and discharging is limited, so should the cell phone battery power used up as much as possible and then charge. But I find on a lithium-ion hp Pavilion ZD7000 battery  charge and discharge cycle test table, on the life cycle of figures is as follows:

Life cycle (10% DOD):> 1000 times

Life cycle (100% DOD):> 200 times

DOD is the depth of the discharge of which the initials.

Can be seen from the table, the number of rechargeable and about the depth of discharge, 10% DOD at the time of the life cycle than 100% DOD’s a lot longer. Of course, if the actual charge equivalent to the total capacity of the relative:

10% * 100 = 1000

100% * 200 = 200, which is the complete charge and discharge, or better than some, but in front of friends do say that some of the amendments: Under normal circumstances, you should have a reservation in accordance with the remaining battery power and then run out of charge to the principle Charge, but if your battery is expected in the first 2 days you can not
To adhere to the whole day, should start on time charge, of course, if you are willing to carry another charger to the office when Bielun.

And you need to charge in order to cope with the anticipated upcoming busy communications will lead to an important event, even if the hp PP2182D battery  is still
There are a lot more than power, then you just charge ahead of time because you do not have a real loss “1″ sub-charge cycle life, it
Is the “0.x” times, but often this will be a very small x.

The remaining battery power and then run out of charge to the principle does not mean that you go to the extreme. And charging the same length of a widespread,
“As far as possible the cell phone’s battery run out of power, it is best to use automatic shutdown.” This is only a matter of fact on nickel batteries,
The purpose is to avoid occurrence of memory effect, unfortunately, it is also spread of lithium batteries on this. It has been because the cell phone battery had
Low warning appears, do not continue to use the charge has been used in automatic shutdown of the case. The outcome of this case, the phone in
Later in the boot of charge and there was no response, had to give customer service overhaul. In fact, this is due to the hp PP2182L battery  as a result of the excessive discharge as a result
Low voltage that does not have the normal charge of the boot and conditions.

3, Li-ion battery for mobile phones boils down to the correct approach, I lithium batteries used in mobile phone charging and discharging of the most important tips are:

1, in accordance with the standards and procedures, charging time, even before the three to do so;

2, When the phone prompts when electricity is too low and should start charging as much as possible in a timely manner;

3, lithium batteries do not need to activate the special method, in a normal cell phone use in lithium batteries would be natural to activate. If you insist on spreading the use of “three times before the 12-hour long activation charge” approach, in fact there will not be the effect.

As a result, all 12 hours long pursuit of the lithium batteries and rechargeable cell phone used in automatic shutdown, are wrong. If you are used to be in accordance with the wrong done, please correct in a timely manner, perhaps not too late.

Of course, cell phones and chargers to protect themselves and control the quality of a good circuit, for the protection of lithium hp DM842A battery  or have guaranteed. Therefore, understanding the rules of the charge is the key, in some cases also may make some concessions. For example, you found your cell phone the night before bed charge, you can also start charging before going to bed. The crux of the matter is that you should know what is the right thing to do, and not in accordance with the deliberately wrong to do.

Waste bins battery trouble

Friday, October 17th, 2008

If the improper disposal of used batteries, which the chemical would seriously endanger the environment. As a result, the city of Kaifeng in the internal part of the special unit set up a number of bins used dell-latitude-d500.html”>latitude d500 battery battery , these have the potential contamination of the waste collected. However, these reporters visited the unit found that as a result of up to collect used batteries can not be dealt with, these bins of used  sony-vgp-bps5.html”>vgp-bps5 battery  has also met with embarrassment.

A company in our city, the walls also keep the  a1078 batterywaste bins in the words of the brush, but the bins have already lost track. The Company Xuzhu Ren’s Office said that in the past, we collected used batteries can not be buried buried, can not throw throw, save in the Office of the thing is not the end had no choice but to the bins removed.

In another unit, the Office of the Staff Wang Xiaoling said: “We are the first two years in the unit set up on the wall of a waste a1012 battery  recycling boxes. Battery, the more the more closed, but the disposal of law. No way to the final, to the bins removed. Now we have the Office of the used  m6091 battery  and a half bags of it. ”

Now, with the community to enhance the general awareness of environmental protection, more and more people are gradually changing their behavior and bad habits, but some of the waste disposal problem has become a problem. I hope relevant departments to be on this guidance, and to come up with concrete ways to dispose of in order to prevent contamination of produce.

Cell stack used roadside residents need not panic too

Wednesday, October 15th, 2008

On the morning of 13, who lives in Long Yan Helu cent of the city reflect Mr. Wang told reporters, said the Dragon Mart in the vicinity of a hundred large pile of used batteries by the roadside, no one to deal with. Reporters learned from the environmental protection department, the city of Wuhu there is no specialized units to dispose of used batteries, dry batteries sold in the market to achieve most of the low-mercury or mercury-free, less pollution, the public need not panic. 661-2391661-2395661-2436661-2441661-2561661-2822661-2927661-2948661-2969A1012A1022A1039A1045A1057A1060A1078A1079A1148A1175A1185A1189E68043LBCAP8M6091M6392M7318M7385M7385GM7385G/AM7426M7462GM7462G/AM7462GAM7621M7621GM7621G/AM7621G/BM7621GAM7621GBM8244M8244GM8244G/AM8244G/BM8244GAM8244GBM8416G/AM8416J/AM8511M8665M8665GM8665G/AM8665GAM8983M8983G/AM8984M8984GM8984G/AM9324M9324GM9324G/AM9324J/AM9325M9325G/AM9325J/AM9326M9326G/AM9338G/AM9338J/AM9572G/AM9572J/AM9756M9756G/AM9756J/AMA348MA348*/ AMA348G/ AMA348J/ AMA458MA458*/AMA458G/AMA458J/AMA561MA561FE/AMA561G/AMA561J/AMC-G3/99MC-G4/17

According to Mr. Wang said that on the 13th morning, he Yanhe Lu Bai-long street mall found piled up a large number of used batteries, is a common 5 and 7, battery, about 1,000 sections, no one came to deal with. “In the past, used batteries have read relevant reports that endanger the environment of used batteries, heavy metals contained in the battery of a threat to human health are also high. So many cell stack used in the street, I am worried that local residents will have an impact.” Wang Mr. Anxiety said.

In the afternoon Mr. Wang said the reporter came to the place and found the discarded used batteries has passed away. According to a nearby shop, he saw someone at the used batteries away, “may be a number of merchants selling the battery expired, for the time being on the street.”

Reporters then interviewed the environmental protection department. It is reported that our city has not specialized units to dispose of used batteries, only some of the waste battery recycling business. Dragon Mart in the vicinity of a hundred abandoned waste batteries may be expired products, may also be recycling business. At present, the market has been dry most of the realization of a low-mercury or mercury-free, and pollution is relatively small. State Environmental Protection Administration and the National Development and Reform Commission and other departments have jointly issued a document in recent years, made it clear that as a result of used batteries contain some of the waste is difficult to resolve, in the absence of an effective recovery of the technology, not to encourage countries to focus recovery has reached a low mercury or mercury-free Waste batteries required.

Battery Maintenance

Wednesday, October 15th, 2008

We love what local lithium inspiron battery to maintain what is right? This problem has plagued many loyal users of laptop computers, including me. In some access to information, not long ago had the opportunity of consulting a professional in the electrochemical and Dr. Reading a well-known domestic battery, deputy director of the Institute. The recently acquired some knowledge and experience to write out for our readers you.

The lithium-ion battery cathode material of lithium are normally composed of active compounds, the negative electrode is a special molecular structure of carbon. Common cathode material for the major components of LiCoO2, charging, the battery added to the polarization of the potential positive force the release of the lithium-ion compounds, embedded negative elements were arranged in layers in the structure of carbon. Discharge, lithium-ion from the lamellar structure of the carbon in precipitation, and re-cathode combination of compounds. Lithium-ion movement have had a current.

Although the principle of chemical reaction is very simple, but in the actual industrial production, to be considered much more practical problems: the cathode material additives required to maintain sufficient number of release activity, the negative electrode materials at the molecular structure of the level needed to design To accommodate more lithium-ion; fill in between the electrolyte is negative, in addition to maintaining stability, but also need to have good electrical conductivity, reducing the inspiron battery internal resistance.

Although the lithium-ion batteries have a little nickel-cadmium battery memory effect, the memory effect is the crystallization of the principle, lithium batteries have virtually no reaction. However, the number of lithium-ion battery charge after the release of capacity will continue to decline, the reasons are complex and diverse. The main negative electrode material itself is a positive change from the molecular level, the anode is on the capacity of lithium-ion hole structure will gradually collapse, plug; from the chemical point of view, the negative electrode material is being passive activity, the reaction appears to form a stable of other Compounds. Physics will appear on the cathode material off gradually, and so on, a word ultimately reduces the battery can be free in the process of charging and discharging of the lithium-ion mobile number.

Over-charging and over-discharge, lithium-ion BAT1194  will be the negative result is permanent damage, from the molecular level, can be an intuitive understanding of the excessive discharge of carbon anode will lead to excessive release of lithium-ion and its film-making structure collapsed, over - Rechargeable lithium-ion would be too much of the peg into a structure where the carbon anode, which makes some of the lithium-ion can no longer be released. This is why lithium-ion batteries are usually equipped with charge-discharge control circuit.

Not suitable for the temperature, will lead to other internal lithium-ion battery to generate a chemical reaction that we do not want to see the compounds, so many of the lithium-ion batteries are being set up between the negative temperature of the protective membrane electrolyte or additives. In the battery reaches a certain temperature, the composite membrane electrolyte membrane hole closed or degeneration, increased battery internal resistance until the circuit, is no longer the battery temperature to ensure that the battery temperature normal.

The deep sufficient to put lithium-ion batteries to upgrade the actual capacity of it? Experts clearly told me that this is meaningless. They even said that the use of the so-called three times before the release of the all-sufficient “activation”, in both of them, Dr. knowledge, it also could not figure what is necessary. But why put a lot of people filling the deep after Battery Information marked in the capacity of this change? Will be referred to the back.

Notebook computer lithium-ion batteries used in general management with a chip and charge control chips. One-chip management in a series of registers, there is capacity, temperature, ID, state-of-charge, discharge, such as the number of values. These values are in use will gradually change. Personally, I think, in notebook computers for use in “a month after the full charge should take a” leading role of these amendments is to be improper, the value of the register, making the battery charge control and battery with a nominal capacity of the line The actual situation.

The main charge control chips to control the C1295  charging process. Lithium-ion rechargeable battery process is divided into two phases, the current phase of the fast charge (when the battery indicator light yellow) and reduced voltage current phase (the battery indicator light flashes green. Filling phase of the fast current, battery voltage and gradually increase To the standard battery voltage, then under the control of the chip into the phase of the constant pressure, higher voltage is no longer sufficient to ensure that they are too, along with the current battery of 0 to weaken gradually increased, and the final charge.

Statistics chip power consumption records through the discharge curve (voltage, current, time) can calculate the sample battery power, this is what we read in Battery Information in the wh. Value. The lithium-ion batteries in use on many occasions, the discharge curve may change if the chip has been no opportunity to once again read out a complete discharge curve is calculated by the power that is not accurate. That is why we need to put sufficient depth to calibrate the battery chips.

Finally, my battery maintenance view is:

1. Deliberately do not have to guarantee that each time a re-release END electric charge;

2. For a period of time to do an Protection of the circuit under the control of the deep to take charge of battery power to amend statistics, but you will not increase the actual capacity of the battery.

3. Do not have long-term battery, should be a cool place to weaken its own internal passive reaction speed.

4. The protection circuit is also able to monitor the 1X793  self-discharge, do not have long-term battery should be sufficient to prevent a certain degree of power in the storage battery self-discharge of excessive lead to excessive discharge of the damage.

In fact, the battery does not take into account the use of too much attention, in other words is also taken into account is not much use. A battery to the use of the number of times, the difference may be more from its own battery manufacturing of individual differences, rather than using the method. Select a good word-of-mouth brand of notebook computers, is the use of long-life battery in the future of one of the security.
