On the whole, there are mainly the following scams:
First, the equipment is highly intelligent and does not need manual operation.
Most of these devices claim that the repair instrument automatically executes all repair procedures when connecting the positive and negative electrodes of the battery, and automatically stops after repair, without opening the cover and adding any liquid, and the repair cost is zero. What's even more amazing is that some devices also have self-checking function, which can automatically determine the maintenance mode and time according to the battery capacity, internal resistance and damage mode.
The truth is that most of these devices are "real chargers, fake reducers". A few so-called "repairing instruments" with pulse function can increase the capacity after charging the battery. If the user has certain maintenance knowledge, the battery life can be appropriately extended; There are still a few devices that have the function of detecting the internal resistance of the battery. It is nonsense to say that these devices have the function of "detecting the capacity and damage mode of the battery". Only a few foreign companies in the world have equipment for testing battery capacity, and the price is expensive, with RMB between 4,000 and 6,000 yuan. At present, the only method to detect battery capacity in China is constant current discharge.
The high degree of intelligence of battery repair instrument does not mean that manual operation is not needed, and "intelligence" does not mean "stupidity", just like a fool camera and a digital camera, the effect and operation method are very different. If this industry is really simple to a fool, I suggest not to get involved: what even a fool can do is bound to be very competitive.
Second, the name "good" equals high technology content.
What negative pulse repair instrument; Positive and negative pulse repair instrument; High frequency pulse repair instrument; Composite resonance pulse repair instrument: composite pulse lead-acid battery repair instrument; Sweep pulse repair instrument: high-frequency combination, positive and negative pulse cycle repair instrument; Microcomputer positive and negative ion combined pulse negative ion scanning battery repair machine; FM high power electronic pulse repair instrument: high frequency pulse+low frequency pulse+high current maintenance+high current activation repair instrument; Automatic frequency sweep vibration and synchronous interference suppression technology; As a new product in recent years, lead-acid battery repair instrument has no corresponding standard in China. In order to facilitate market promotion, manufacturers name their own equipment, which is dazzling and difficult to distinguish between true and false.
In fact, at present, the effective repair instruments for battery repair are pulse technology. Because each manufacturer has different core technologies and uses different pulse waves, the effect of battery repair is very different. At present, the lead-acid battery repair instrument mainly solves the sulfide phenomenon of the battery. To break the bondage of these sulfate layers, it is necessary to raise the energy level of atoms to a certain extent. At this time, the electrons added to the outer atom are activated to the next higher energy band, so that the atom is released from the bondage. Each specific energy level has a unique resonance frequency, and some energy must be provided to make the activated molecules migrate to a higher energy level. Too low energy can't meet the energy requirements for transformation. Some repair instruments can meet this requirement and quickly remove the sulfide phenomenon of the battery; However, some so-called maintenance instruments can only be charged during the use of the battery to delay the occurrence of battery vulcanization. As for the so-called most advanced composite resonance pulse repair instrument, it is just a gimmick played by manufacturers. The pulse wave generated by all pulse restorers in the repair process will have harmonic resonance with lead sulfate, but some are large or small.
Even more bizarre is that some people claim that his equipment is: intelligent power generation, universal emergency charging, battery repair multifunctional machine; What is even more ridiculous is that some people claim that his equipment is a temperature-rising curing instrument. Batteries with softened plates can be repaired by heating and curing. As for some manufacturers' opinions about their restorations, we believe that the lead-acid battery restoration technology has developed to the fourth generation so far, and it is still too early to say which generation the lead-acid battery restorations have developed to.
1, correct understanding of lead-acid battery repair
To some extent, some failed batteries can be repaired by certain methods and equipment, but not all failed batteries can be repaired. For details, please refer to the misunderstanding of battery maintenance of electric vehicles.
2. At present, there is some confusion in the lead-acid battery repair market. I hope everyone can distinguish carefully. It is not a device or method that can repair any type of faulty battery.
3. Several major scams of lead-acid battery repair.
Third, the magical repair effect
Short repair time; Can restore more than 90% of the original capacity; Extend the battery life by 3-5 years; It is the propaganda language of many manufacturers.
Some manufacturers claim that the repair time of general12v (10-14ah) batteries is about 20-70 minutes, and that of 17-22AH batteries is about 30- 100 minutes. More boldly, it is claimed that it takes 10 minutes to repair the10 battery and 20 minutes to repair the 20AH battery.
Some claim that the repair rate of the electrode plate is vulcanized and softened, the battery is damaged due to micro-short-circuit, or the battery that can be put into the battery box is above 90% (the battery with severe short-circuit and open circuit cannot be repaired), and the repair rate of the old battery without screening can reach 80%. Bolder people claim that it can bring any used battery back to life; Others claimed that the repaired battery not only restored the original nominal capacity, but also analyzed the internal structure of the battery through professional instruments, which is more scientific than the new one! Really: how bold people are and how productive the land is.
The production of new batteries and the recovery of waste batteries are a rather complicated process. No matter how advanced the repair instrument is, it also charges the battery and has no other special function. It is nonsense to say that the softening of the plate can be cured by heating up. When the battery was repaired, the temperature rose. Without the help of other external heating and cooling equipment, the temperature will not rise. If the temperature rises, it means that the charging current of the equipment is large, which will only damage the battery. As we all know, during the charging process, high temperature will charge the battery. Moreover, a good maintenance instrument will not raise the battery temperature during maintenance.
As for the softening of the positive plate, lead dioxide, the active substance of the positive plate, generates alpha lead dioxide and beta lead dioxide in the electrochemical reaction process. These two components are similar to the relationship between branches and leaves in the positive plate. Alpha lead dioxide is a branch and beta lead dioxide is a leaf. During the discharge process, lead dioxide in the positive plate reacts electrochemically with sulfuric acid in the battery to generate lead sulfate, which is reduced to lead dioxide during the charging process, and lead sulfate generates alpha lead dioxide and beta lead dioxide during the reduction process. At present, under the existing conditions, only lead powder can be melted and decomposed to produce electrode plates, and then batteries can be manufactured.
Fourth, raise the banner and be a tiger skin.
(1), a lot of medal certificates: what international gold medal; China Top Ten Battery Repair Instruments; × Depending on the listed brand; Xx focuses on promoting products; China ×××× Center and China ×××× Center, key promotion units of China XX Product Quality Assurance Center; Has passed the ISO900 1-2000-2000 international quality management system certification. Wait, wait, wait, wait, wait, wait, wait.
The truth is that lead-acid battery repair, as a new industry (strictly speaking, it is still a little early to be called an industry because it has not yet formed an industry), has not attracted the attention and concern of relevant state departments. Enterprises develop their own equipment according to the relevant technologies they have mastered, and the state has no relevant product standards. How does this award prove that the relevant state departments will never give awards to products without national standards like some irresponsible people? Only the so-called "China XX Association (Center)", which is similar to the "National Dental Prevention Group", issues a large number of certificates and medals for economic benefits and enterprise needs.
(2) Strong technical force: the company has gathered a group of professors, experts and doctors from famous universities; After years of research and development by XX University and our expert team; Relying on the technical strength of XX University and Institute of Automation of XX Academy of Sciences; The company is located in a famous university or well-known unit or high-tech park.
At first glance, people have to feel that its technical strength is very strong. In fact, many of these enterprises are "rich people" and set their offices in well-known units. Their "worth" doubled immediately, and the ugly duckling became a white swan. It is easy to believe that the company has strong technical strength intentionally or unintentionally. There is a company located in a famous university, which is called "X technology, X patent". After the customer bought the battery for equipment maintenance, the excess liquid was poured out. After the charge-discharge test, the battery capacity decreased. When consulting him, he replied that he had dumped the active substance. Even the active substance doesn't know what it is, so its level can be seen.
The lead-acid battery repair technology appeared in China in the mid-1990s. Due to the limitation of conditions, this equipment does not have the pulse function. The battery was repaired by high current charging, overcharging, repeated charging and discharging, water treatment and other methods. These repair methods can only repair lightly vulcanized batteries, and the effect is not ideal. They didn't get further promotion and soon disappeared.
The application of pulse technology to scrapped lead-acid batteries appeared at the beginning of this century. This method is effective for severely vulcanized batteries, because it is still in the research stage and has no practical application. The pulse lead-acid battery repair instrument entered the market and appeared at the end of 2003. It was jointly developed by a company in Shandong and relevant experts in Tsinghua University. In 2004, the relevant information appeared on the internet and related newspapers and periodicals, that is, there is basically only one kind of repair instrument and repair liquid, and there are more than a dozen kinds of repair liquid (powder) without repair instrument.
In the first half of 2005, the relevant information gradually increased. In the second half of 2005, BLACKPINK began to appear as a liar with a keen sense of smell, taking advantage of people's lack of relevant knowledge to cheat. Two electric car chargers and one car charger competed for more than 4000 yuan as a repair instrument. At this time, the information about lead-acid battery repair technology on the Internet is not very rich, and the deceived person can't provide more knowledge about lead-acid battery repair. If there is a website, the information is not comprehensive and very unprofessional.
In 2006, with the gradual enrichment of information about the repair technology of lead-acid batteries on the Internet, more and more manufacturers participated in the repair of lead-acid batteries, and more and more people rushed out of the rivers and lakes to fish in troubled waters. Most of them claim to be engaged in this industry for many years, many claim to be "the first in China", and the websites are becoming more and more "professional", which is more deceptive, making it difficult for latecomers who come into contact with this industry for the first time to tell the truth.
How do novices prevent being cheated?
First, the correct investment mentality.
At present, many people engaged in this industry have speculative psychology, and they are partial to hearing and believing. They are superstitious about the so-called "automatic repair stops automatically, and the repair process is automatically completed when charging, without opening the lid and adding any chemicals, and the repair cost is zero". If you want to get something for nothing, you can easily make a big profit. It should be noted that "there is no pie in the sky", and any technology will not be so simple.
Most people who are easily deceived have the mentality of "getting rich" and "hating the rich": they always hope that the less they invest, the better, and the higher their profits will be. Usually, it is easy to "envy" the success of others, listen to the wind is rain, and blindly believe in false propaganda. I don't want to invest, I don't want to do services in a down-to-earth manner, I want to be opportunistic,
You can make a fortune, but you often fall into the trap of others; To say that such people have the mentality of "hating the rich" is to blindly believe that some people say that the equipment with low cost and high price is making huge profits. It should be noted that although the maintenance instrument also charges the battery, it has considerable technical content, which is very different from the ordinary charger in terms of cost and sales volume. It can be said that the high price is not necessarily a good prosthesis, and the low price is definitely a prosthesis with poor effect, even a fake prosthesis with a real charger.
According to the statistics of authoritative organizations, the failure rate of entrepreneurs with the mentality of "getting rich overnight" is as high as 97.4%, and most of them end up being cheated. It takes at least 1.5 years for a successful entrepreneur to achieve something from scratch. Investors should rationally distinguish between "getting rich" and "getting rich", turn their desire to get rich into passion, and realize their dream of wealth as soon as possible.
Second, learn more about relevant knowledge.
Don't be afraid to spend money, check it yourself, and bring a battery to verify the repair effect if necessary. For companies that don't visit for a long distance, ask them to provide a list of customers who have purchased equipment and call him to ask about the maintenance effect of the equipment. Through comparison in many aspects, you can enrich your relevant knowledge, distinguish the true from the false, and not be fooled.
The authenticity of his technology (equipment) can be verified from the following aspects: (1), whether the equipment automatically repairs and stops, and automatically completes the repair process without opening the cover when charging. If so, his equipment is a charger, and the real maintenance instrument can only prompt and will not stop automatically. Moreover, the battery will be short of water during use, and it is impossible to repair the battery without opening the cover and adding liquid. (2) Look at the output power (current) of the equipment: the equipment with low power takes a long time to maintain, and the maintenance effect is not ideal. In the normal use of the battery, using it for maintenance and charging can prolong the service life of the battery, and the effect of repairing the battery that is close to scrapping is not ideal; For equipment with high output power, increase the current appropriately during maintenance. If the battery temperature rises rapidly, it may be charged with a large current. (3) The design life of lead-acid batteries is 3-5 years. Because it is easy to form sulfation in the process of use, it is often scrapped after 1-2 years, and it is very effective to use 1-2 years after repair. It is said that it can be used for 3-5 years after repair. Don't trust it easily whether it is the most advanced maintenance equipment or not.
Third, don't be fooled by superficial phenomena.
Some companies dare to claim that they are patented products with well-known trademarks in China less than one year after registration, and some companies have many honors, saying that "China is the first and the industry is leading". No matter whether the company is located in a well-known university or claims to be the first in China, don't take it seriously. Make a decision after many investigations, and don't be influenced by superficial phenomena.
