Digital battery

Wu citizen members of the public to give the market for the repair of the battery, “legislative rule” message to see the network has caused a lot of reader attention. Everyone has an idea: Since people know that Wu market electric car VGP-BPS9/S VGP-BPS9/B battery repair, delicate, why not take a great Jie Mi, so that we can no longer be duped?

 

3, Wu called on citizens to be journalists, he learned the details of the market for electric cars battery maintenance “hidden rules” and how to avoid these sensitive, responding to proposals put forward.

 

Tricky, this one: Can the proposed amendments change the battery

 

Electric bicycles are three main parts: engine, battery (batteries) and the controller. Three parties, the high rate of battery failure, sensitive, both hidden in cells.

 

Many consumers feel the electric car “Er Meijin”, or charge the battery can not be taken to the maintenance activity, which often heard the suggestion: “You can not use the battery and dispose!

 

Why do companies do to encourage consumers to replace the battery? It turned out that the battery manufacturers to dealers the life of the battery is often more than a year, while the dealer sold to consumers at the promise of shelf life are often not exceeding one year. Thus, if consumers in about a year, 346970-001 367759-001 battery problems, you must re-purchase of the battery. Batteries May also manufacturers warranty period, the registered dealer for manufacturers to get the old batteries could be in exchange for a new set of batteries, but consumers need their own money to buy a new battery.

 

Yes, under what circumstances the battery at the end for her? Wu citizens say that battery problems are many reasons, but outside of a drum package, gunpowder, “off grid and plate short circuit, damage to the shell of these four cases, batteries in general do not change as long as the service can continue to use.

 

Our approach: drum package is the result of excessive battery charging, the battery has been distorted drums, consumers may feel their hands touching, shell damage can also be visual. “Off powdered and plaques on isolated and short-circuiting the need to open the battery before we can see that if the maintenance contractors for the replacement of these two reasons, consumers can make maintenance providers on to open up the battery monitor.

Tricky, 2: “Trade-ins” and the “old for old”

 

One year shelf life period of the battery problems and some vendors will swap the same model for consumer products. Some consumers may find that the number of batteries for most problems over the frequency, the crucial point where?

 

It turned out that a number of repair shops to reduce the rate of battery scrap to reduce the loss of battery manufacturer, the “three guarantees” period of batteries back to back multi-taken ” repairing the old with the old approach. “Some will replace the defective batteries lead, and some use more than half a year to complete the electrolyte of the battery or the aging of the battery to eliminate hardening treatment, there are other batteries will be assembling and disassembling.

 

One can imagine the quality of refurbished batteries, consumers have a new set of money, you bought is the addition of new batteries. These batteries are generally a very short life, can not guarantee that the use of time. IBM ThinkPad R52 battery IBM ThinkPad T40 battery

 

To meet the challenges: how to identify old batteries? Wu citizens, first, to see joint Department no trace of solder or hand and the second is to look clean and not clean shells, batteries refurbished, there will always leave clues used, third is new when you first check the battery is changed the packaging of the battery, it is best to check by yourself and then break the seal.

 

Tricky, 3: The new battery is guilty of fraud

 

Wu said that the citizens, since most consumers do not understand the market for electric vehicles battery and a low maintenance new car battery are also likely to be maintenance companies “perpetrating a fraud.”

 

For example, bought a new high capacity 48V/20A battery electric vehicles, in repair, if the salary is not careful, the new battery may be replaced by a 48V/17A. Is also a new battery, the price difference is not small: 48V/17A battery 48V/20A PA3395U-1BRS PA3399U-1BAS battery cheaper than the 100 yuan or more, the corresponding power is reduced.

 

Our approach in the repair of electric vehicles before, we must clearly understand the main parts of electric cars - batteries, electric motors and related parts of the model, the interview should be checked at the end.

 

Tricky, 4: Li Gui, “as” Li Kui “sell

 

Wu said that people at present the city electric vehicle battery market, the common brands are five or six years because the battery there is a huge advantage, the market there were some imitations.

 

The “days” to the mark, for example, this battery is produced by a manufacturer, Zhejiang, is a national inspection-free products, many consumers are the most brand recognition. However, there are now on the market entitled “Luoyang days can” stack, “Days of Luoyang may” and Zhejiang “days can”, just as marked in the central part of the battery are great ‘days may ” the mark, just below the use of small fonts are less Luoyang origin labeling. Speaking are “days of” selling and may also be the same price, available until a big difference! apple MacBook 13 inch battery  apple MacBook Pro 15 inch battery

 

Our approach: selection of a new battery or replace the battery is sure to see the origin and related technical specifications and instructions as well as the introduction to the compatibility of business. Repair shop is the use of consumers does not understand the quotes of “mischief”.

 

Tricky, 5: Repair of distilled water as liquid

 

Liquid battery repair is diluted sulfuric acid and some chemical additives, according to a certain proportion of liquid. Generally, a group of four batteries, the cost to repair the battery of a normal fluid is 80 to 100 yuan per month.

 

However, if you use distilled water or purified water instead of liquid repair battery, “fix” the battery does not take long for the bad, and they must re-repair. Because distilled water is not a fixed liquid water in the case of the battery more than distilled water, before there are results. If the battery is missing in acid, then placed in the water, battery performance will be worse.

 

Citizens Wu said that in cell repair, maintenance staff to tell you if the use of “rehabilitation of water (liquid), and the battery charge is 10 yuan each, when is used in the battery is certainly not a real solution. LCBTP03003  Aspire 3000 battery

 

Our approach in maintaining the battery, the maintenance personnel to see added is marked with a regular manufacturer and address of the repair fluid, but also allows the maintenance personnel can use after the time indicated maintenance batteries. Because the lead in repairing the battery acid, adding the liquid cell can repair the battery capacity recovery was greater after repair using the time should be longer.

 

Tricky, 6: a battery for a button to see how the change

 

Packs of battery electric vehicles, consisting of three or four batteries, and sometimes occur in what situation a bad battery. Some consumers feel sorry for the Money: Since the battery is just all wrong, then replace the bad singing together. Some maintenance providers Mozhun consumer psychology will also recommend that you change only a fragment of the battery. For now be careful: all words any problem with the VGP-BPL8A  VGP-BPL9 battery, the key to see how changed.

 

Because each battery voltage is not the same as the other, there will be a low voltage difference, even in the same factory produced the same batch of cells, we can not eliminate this voltage difference. Individual cells in series into a stack, there will be the battery voltage “consistency” problem, the battery voltage “consistency” is poor, it will significantly affect battery life. It is as if the effort everyone is different, some people with different resistance to act on an object, the greater the difference in their own strength, accidents most likely.

 

Consequently, some consumers will find a group of them together after replacing the battery, a battery when the whole can not be used, and this time, companies are waiting for you to take money for new batteries ones.

 

Our approach: To replace a battery, be sure to let the maintenance contractors must be properly measured, the smallest piece of the selection pressure to replace the batteries.

 

Citizens Wu concluded that the buyer is not the essence of the seller, the seller of small ways to make money without end. To clean the market for electric vehicles battery maintenance, in addition to the standards of marketing and business self-regulation, rights of consumer protection should also establish a sense of documentary evidence left behind all care. In addition, the choice of replacing the battery should be the first of a guaranteed quality of the battery brand, covet not cheap to replace in the informal stalls, you can maximize risk aversion

Li-maintenance errors ion battery doubts

 

Notebook battery is something more important, its status is directly linked to a mobile environment in the absence of power in the ability to work. Batteries for laptops is also a major consumer of parts so related to the maintenance notebook battery and wise use are also frequently discussed topic. However, some users maintain some of the understanding is wrong, the following should do something to explain. apple iBook G4 12 inch battery  apple iBook G4 14 inch battery

 

Nickel-metal hydride batteries are now equipped models have basically will not see, the universal application of a lithium-ion batteries. General lithium-ion battery cycle life of 300 to 500 charge-discharge. But this does not mean it can only rarely use the extended life battery. Cells of origin as factors in the physical work environment can influence, but the main reason leading to the loss of cells caused by oxidation of the battery internal resistance increases, which explains why Many users complain that they are fully recharged in use why suddenly had no electricity. It may therefore be understood that the problem is that when the end of the assembly of the battery production line, its internal life, the clock, then start walking, even if you do not set aside the battery, it can be to a certain extent, the loss rate of only delaying the battery. However, in other words, if the battery still sits on the side of the meaning of laptops mobile speak?

 

Material for lithium-ion battery cathode is generally formed by a lithium-active compounds, the negative electrode is a particular molecular structure of carbon. Common Cathode Material for key elements of LiCoO2, charging, added to the PA3285U-3BRS PA3383U-1BRS battery positive pole of electric potential to force the release of compounds, the lithium ions, incorporate negative elements arranged in a lamellar structure of carbon. Discharge, lithium-ion lamellar structure of carbon precipitation and re-cathode combination of compounds. Lithium-ion movement generated a current. Although the principle of chemical reaction is very simple, but in actual industrial production, the practical problems must be considered much more: the cathode material additives required to maintain multiple load-discharge activity, the electrode material If not, who should design the molecular structure of the class to accommodate more lithium-ion battery; fill in the electrolyte between the positive and negative electrodes, in addition to maintaining stability, but also need to have good electrical conductivity, reducing the resistance of the internal battery.

 

Although lithium-ion batteries for low-nickel cadmium battery memory effect, the memory effect of this principle is that the crystallization in lithium batteries will have little reaction. However, the capacity of lithium-ion battery charge after repeated discharge will continue to decline, its causes are complex and diverse. Is mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ions on the hole to accommodate the structure will gradually collapse, taken from a chemical standpoint, is the material anode active is passive, there is another side to form a stable compound. Physics will appear on the cathode material to fall off gradually, etc., in short, which ultimately reduces the 346970-001 367759-001 battery charge-discharge process can be free to move many lithium ions.

 

Overload and excessive discharge, lithium-ion batteries will be positive and negative cause permanent damage, from the molecular level of intuitive understanding, an excessive discharge of carbon anode will lead to excessive release of lithium-ion shows the lamellar structure collapsed, over - Rechargeable lithium-ion battery will go too hard in the carbon negative, causing some of the lithium-ion batteries can not be released. Therefore, the lithium-ion batteries are usually equipped with charge-control circuit discharge.

 

Not suitable for temperature, lead to lithium-ion battery inside the reaction of other chemicals that we do not want to see both of the lithium-ion batteries are put in place between the negative temperature-controlled protection by a diaphragm or electrolyte additives. In the battery temperature in a given case, the composite membrane electrolyte membrane hole closed or degeneration, increased resistance of the internal battery until the circuit, the battery is no longer to warm up to ensure that the battery charging temperature is normal.

And loads of deep-discharge lithium-ion batteries can improve the real capacity? According to experts, the answer he did not make sense. Experts say that even the so-called triple full charge-discharge prior to use of “activation” in their knowledge of Mr. Lane does not include this as a need. Why do people provided, however, after the charge deep-discharge capacity of the battery information label will be possible where a change? Will be mentioned later.

 

Notebook Computer lithium-ion batteries are generally the management of the chip and chip load control. What chip running a series of records, there is capacity, temperature, identity, charge state, the values of firing rate. These values are in use will gradually change. Personally believe that the instructions for use in notebooks in the “Use a month should post a full load” approach to a role is now to set those records where the wrong values, making the burden of Battery control and the nominal capacity of the battery match the real situation.

 

Responsible for controlling the main control chip, the battery charging process. Lithium-ion battery charging process is divided into two phases, phase constant current fast charge (when the LED on the battery in yellow) and constant voltage stage down (the battery indicator blinks green. Constant current phase of rapid charging, the battery voltage is gradually increased voltage standard battery, and then transferred to constant pressure in the control phase of the next chip, the voltage does not increase to ensure that no overload, battery current, with the rising gradually weakened to 0, and the ultimate end load.

Statistics smart energy consumption by recording the discharge curve (voltage, current, time) can calculate the battery power of the sample is what we read in the battery information inside World Heritage. Worth. The lithium-ion batteries in repeated use, the discharge curve will change if the chip has not been an opportunity once again read out a complete discharge curve, which is calculated from the electricity that is not true. Therefore, the need to support deep discharge to calibrate the battery chips.

 

A good battery maintenance is required, so many people have asked how to protect a battery but it will not be early retirement for life on this problem. As the battery life is primarily determined by the number of charge cycles in order to avoid frequent use of the battery can be said that one of the most fundamental way, that uses the power of the environment as far as possible does not use batteries.

 

This leads to a question, that is, if energy use when the battery removed from the machine, it is indeed a problem that people in the head. However, the condition of high load and high temperature accelerated the decline in battery capacity. I now invite all imagine that if you do not remove the battery, the laptop because of the role of the charging protection circuit, so that the battery is maintained at 95-100% of the charge state to a high when the battery in which the temperature at least 30 ° C, so if it is hot, the temperature will be higher, so the stability of the supply alternating current, we should try to remove the battery to the using computers. If you are planning a long period does not use batteries, charge the battery to 40% should be placed in a cool place after the save. If the battery is fully charged, will be placed at high temperatures, so that the battery will cause damage. Because load of 100% within 60 ° C environmental conservation, 3 months after the battery capacity has dropped by 40%. Set aside for the preservation of the battery should be at least one month will be used once the battery Zhuangshang Qu, recharged to prevent the loss of activity of the ion.

Similarly, dust and moisture also acts as a battery killer role, they will destroy the circuit of the battery and accelerate the oxidation of the internal battery, so for those of long-term preservation of the battery You can place a layer of thin sheets of low-grade dust and breach of the humidity.

 

In addition, lithium batteries how reasonable prices and dump? As lithium-ion battery that can power a small memory effect is negligible, so it loads half of the injury is not too great, and his fear most is the excessive discharge (full discharge). Lithium-ion batteries often the result of low flow excessive battery can be left in advance, such as bios discharge, discharge procedures, and even connected to the discharge bulb is the best way to do see no alternative but to not try. So, for lithium-ion batteries need not wait until the charging 0%.

 

To summarize, the maintenance of the battery are a few suggestions:

 

1. No need to ensure that whenever a new full release END electric charge;

 

2. A period of time to make a protection circuit placed under the control of the profound power of the battery charge to change the statistics, but it will not increase the actual capacity of the battery;

 

3. A long time without the battery must be placed in the shade to weaken its internal autonomy, the reaction rate passivation;

 

4. Protection circuit is also capable of monitoring battery discharge, in the long term without the battery must be charged to a certain degree of power to prevent self-discharge of batteries for storage in the discharge of excessive lead to excessive damage to the battery.

 

In fact, there is not much to take into account the use of the battery of attention, in other words, is the need did not have much effect. The number of times a cell can use the differences are mainly coming from the battery itself, the making of individual differences rather than use. Choose a reputable brand of notebook PCs is the use of long battery life in the only future of the security.

When we bought a new digital camera, the first thing to do is give the rechargeable lithium battery, charging circuit for battery management in the lithium internal load is a complex process, it is necessary to ensure that lithium batteries can be filled to ensure that the performance of lithium batteries, but also ensure that lithium batteries can not overload, because if the process of collecting the burden of lithium Laptop battery current is too large, or the loading time is too long, too late to produce oxygen is consumed, it may result in pressure increases, the deformation of the battery leaks and other undesirable phenomena in severe cases can cause an explosion or fire, they must be charged in accordance with methods specified.

 

Many friends believe that the use of the three previous lithium batteries should charge more than 16 hours to activate the battery completely, in fact it is so no basis for this is the year the popular Ni-MH or Ni-Cd battery charging method for lithium-ion batteries which do not apply. Because the nucleus of the lithium-polymer battery and no memory effect, as well as 3 hours or if the hub is quite possible, and most shippers have a random display, the display if the loading was completed then you can unplug power, no longer have to wait so long!

 

In general, lithium batteries can generally be charged 300-500 times by using different methods and frequency of your digital camera batteries may be used for several years, it may be for one year, if the Maintenance is very important in times of peace. As required by the IEC, the Dell Inspiron 1420 battery must be at a temperature of 20 -5 ℃, humidity (65 - 20)% in terms of storage, to avoid placing very hot space. In general, the higher the temperature of the battery storage capacity remaining rate is lower, and vice versa. So we had better battery stored in a cool, dry, particularly in the travel time even more care should pay attention to a good camera battery, and try to avoid the battery with a general store with metal objects for prevent the onset of short-circuit the battery easy to travel when the battery is dirty, if May result in battery life, “loss” to avoid loss of power problems, we must pay attention maintaining the battery and the battery contact points at both ends of the inside of the lid clean. If the battery is the dirty surface, then we will have appropriate use of a soft, dry and clean and gently rub the surface of the battery to keep the battery clean.

 

When long Do not use batteries, we have the battery from the digital camera is best to take it down, because at that time even if the digital video camera was turned off, the system they will always low battery output current, thus shortening the life of the hp 346970-001 battery. Stored for an extended period suggested that the drum part of the landfill to restore the original capacity of the battery and discharge performance. Should be taken to avoid a complete discharge, because the lithium battery is low maintenance, this part of the discharge the battery completely discharge lasting more than, if possible, should avoid frequent full discharges, c ‘ is not to use device battery shutoff date, as the electricity shortage has prompted a lot of time to recharge should be updated.

 

If your regular on-cell lithium battery discharge could have disastrous consequences, especially in high current discharge excessive or repeated over-discharge, but not short-circuit discharge, because the destruction of more great impact on the apple A1022 battery. Because he had the battery discharge pressure is increased, the reversibility of damage positive and negative active material, the decline, although the charge may be partial recovery, capacity, it will be evident over time, your lithium battery that can power the time will be shorter Yuel!

 

Also necessary to remind everyone that the accessories for today’s digital cameras in all, the lithium battery counterfeiting and sale of the bad situation is particularly serious because it has obtained illegal profits are highest. Counterfeit unstable performance of lithium batteries, coupled with the work of today’s digital cameras large, the actual use of fake batteries working hours shorter than the real thing in many, and some batteries used for the first false positive results, but the charge could be found after a few power performances dramatically. Although the purchase of fake batteries may get an instant map cheap, but its consequences are incalculable, large companies have also issued a statement, the use of false all the consequences of lithium batteries, the company’s is not any accountability, it is proposed that we still want to buy lithium batteries original is good, be careful before you buy, if he could put the camera can not give you repair the damage!
