Several major scams for repairing lead-acid batteries

1. Correctly understand the repair of lead-acid batteries

Partially faulty batteries can be repaired to a certain extent using certain methods and equipment, but not all faulty batteries can be repaired. For detailed information, please refer to "Uncovering Misconceptions in Electric Vehicle Battery Repair"

2. There is a certain degree of confusion in the lead-acid battery repair market now. I hope everyone can carefully distinguish. No device or method can repair any type of faulty battery.

3. Several major scams for repairing lead-acid batteries

Since the invention of lead-acid batteries more than a hundred years ago, they have firmly occupied the majority of secondary batteries with excellent performance and low price, and are the largest and most widely used chemical power source in the world. The fatal weakness of batteries is their short lifespan. Although their design lifespan is 4-10 years, their inherent characteristics result in a lifespan of generally 1-2 years, causing unnecessary economic losses to users and increasing resource waste and environmental pollution. Over the years, knowledgeable people at home and abroad have made unremitting efforts and explorations to create many effective repair methods to extend the service life of batteries. In a few years, battery repair technology has gone through four generations and become increasingly sophisticated. In recent years, the domestic market has become increasingly hot, and the battery repair industry has gradually formed an immeasurable huge industry. Like other emerging industries, there are always some unscrupulous people who take advantage of people's lack of understanding of this emerging industry to commit fraud. The accusations and insults of those who have been deceived continue to be heard, and these people originally wanted to make a living and improve their living conditions, but unexpectedly fell into trouble as a result, completely losing confidence in this industry, making more battery consumers feel that this is a scam, invisibly increasing the difficulty for practitioners who later entered battery repair.

Overall, there are several major scams:

1、 The device has a high degree of intelligence and does not require manual operation.

Most of these devices claim that the repair machine can automatically perform all repair procedures by connecting the positive and negative terminals of the battery without manual supervision. After the repair is completed, it will automatically stop without opening the cover or adding any liquid, and the repair cost is zero. Even more amazing is that some devices also have a self checking function, which can automatically determine the repair mode and time based on battery capacity, internal resistance, and damage mode.

The real situation is that most of these devices are "real chargers, fake repairers". A small number of so-called "repair devices" with pulse function can increase their capacity by charging the battery. If the user has certain repair knowledge, the battery life can be appropriately extended; There are still a few devices that have the function of detecting battery internal resistance. It is completely groundless to say that the devices have the function of "detecting battery capacity and damage mode". The equipment capable of detecting battery capacity is only produced by a few foreign companies in the world and is expensive, ranging from 4000 to 6000 yuan in Chinese yuan. The method for detecting battery capacity in China can only be through constant current discharge under current conditions.

The high level of intelligence of battery repair equipment does not mean that it does not require manual operation. "Intelligence" does not mean "foolproof", just like a point and shoot camera and a digital camera, there is a world of difference in both effect and operation methods. If this industry is really simple to the point of being foolish, it is recommended not to get involved: what even fools can do is bound to be highly competitive.

2、 The name 'good' is equivalent to high technological content

What negative pulse repair device; Positive and negative pulse repair device; High frequency pulse repair device; Composite resonant pulse repair device; Combination pulse lead-acid battery repair device; Sweep frequency pulse repair device; High frequency combination, positive and negative pulse cycle repair device; Microcomputer positive and negative ion combination pulse negative ion scanning battery repair machine; FM high-power electronic pulse repair device; High frequency pulse+low-frequency pulse+high current maintenance+high current activation repair instrument; Automatic frequency sweep resonance and synchronous interference suppression technology; As a newly emerged product in recent years, lead-acid battery repair equipment does not have corresponding national standards. In order to facilitate market promotion, manufacturers have named the equipment themselves, which is confusing and difficult to distinguish between true and false.

In fact, the effective repair equipment for battery repair now uses pulse technology. However, due to the different core technologies mastered by each manufacturer and the different pulse waves used, the repair effect of batteries varies greatly. The current lead-acid battery repair equipment mainly solves the sulfurization phenomenon of the battery. To break the binding of these sulfate layers, the energy level of the atoms needs to be raised to a certain extent. At this time, the electrons added to the outer atoms are activated to the next higher energy band, freeing the atoms from binding. Each specific energy level has a unique resonant frequency, and some energy must be provided to enable the activated molecule to migrate to a higher energy level state. Energy that is too low cannot meet the energy requirements for transition. Some repair devices can meet this requirement and quickly remove the sulfurization phenomenon of the battery; Some so-called repair devices can only be used to charge batteries during their use, in order to delay the occurrence of battery vulcanization. As for the so-called state-of-the-art composite resonant pulse repair device, it is just a gimmick played by manufacturers. All pulse repair devices generate harmonic resonance with lead sulfate during the repair process, with varying degrees of resonance.

What's even more bizarre is that some people claim that his device is a multifunctional machine that combines intelligent power generation, universal emergency charging, and battery repair;

Even more ridiculous is that some people claim that his device is a temperature curing apparatus. Batteries with softened electrode plates can be repaired by heating and curing.

As for some manufacturers claiming that their repair equipment is the fourth generation, we believe that the lead-acid battery repair technology can be said to have developed to the fourth generation so far. As for the proposal of how many generations the lead-acid battery repair equipment has developed, it is still too early.

3、 Magical repair effect

Short repair time; Can restore over 90% of the original capacity; Extend battery life by 3-5 years; It is a promotional slogan used by many manufacturers.

Some manufacturers claim that the repair time for a typical 12V (10-14AH) battery is about 20-70 minutes, while the repair time for a 17-22AH battery is about 30-100 minutes. Even more daring claims that it takes 10 minutes to repair a 10AH battery and 20 minutes to repair a 20AH battery.

Some claim that the repair rate for batteries with sulfurized or softened electrode plates, single cell micro short circuit damage, or batteries with charging bulges (which can still be packed into the battery box) can reach over 90% (severe short circuits and open circuit batteries cannot be repaired), and the repair rate for old batteries without screening can also reach 80%. Even more daring ones claim that they can revive any discarded battery; Some people claim that after repair, the battery has not only regained its original nominal capacity, but also its internal structure has been analyzed by professional instruments and is even more scientific than the new one! It's true: how bold people are, how great the land is.

The production of new batteries and the recycling of waste batteries are quite complex processes. No matter how advanced the repair equipment is claimed to be, it only charges the batteries and does not have other special functions. It is nonsense to say that it can heat up and solidify, or repair the softening of the electrode plates. The temperature of the battery rises during repair. Without the help of other external temperature control devices, the temperature will not rise. If the temperature rises, it indicates that the device is charging with high current and will only damage the battery. As is well known, electric vehicle batteries can be charged at high temperatures during the charging process. A good repair device will not increase the temperature of the repaired battery.

As for the softening of the positive electrode plate, it is because the active material lead dioxide in the positive electrode plate generates alpha lead dioxide and beta lead dioxide during the electrochemical reaction. These two components in the positive electrode plate are similar to the relationship between branches and leaves. Alpha lead dioxide is the branch, and beta lead dioxide is the leaf. During the discharge process, the lead dioxide in the positive electrode plate reacts electrochemically with sulfuric acid in the battery to form lead sulfate, which is then reduced to lead dioxide during the charging process. During the reduction process, lead sulfate generates alpha lead dioxide and beta lead dioxide. As the amount of beta lead dioxide gradually increases, the softening phenomenon of the electrode plate is formed. Under current conditions, only lead powder can be melted and decomposed to produce electrode plates, which can then be used to manufacture batteries.

4、 Raise the flag and make tiger skin

(1) A bunch of medals and certificates: international gold awards; Top 10 National Battery Repair Devices; Brands on the list of X TV; Key products to be promoted; The China Center for Anti Counterfeiting and the China Association for Anti Counterfeiting have dual monitoring systems for anti-counterfeiting products; China XX Inspection Association's full process quality monitoring products, China XX Inspection Association's quality and reputation guarantee products; Key promotion unit of China XX Product Quality Assurance Center; We have passed the ISO9001-2000 international quality management system certification. Wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait.

The real situation is that lead-acid battery repair, as an emerging industry (strictly speaking, it is still a bit early to be called an industry because it has not yet formed), has not attracted the attention and attention of relevant national departments. The equipment independently developed by enterprises based on their relevant technologies does not have relevant product standards in the country. How can this be proven by awards? Relevant national departments will never irresponsibly award products without national standards. Only the so-called "China XX Association (Center)" similar to the "National Dental Prevention Group" issues a large number of certificates and medals for economic benefits and the needs of enterprises.

(2) Strong technical strength: The company has gathered a group of professors, experts, and PhDs from renowned universities; Developed by a team of experts from XX University and our company after years of research and development; Relying on the technical strength of XX University and the Automation Research Institute of XX Provincial Academy of Sciences; The company is located within a renowned university, unit, or high-tech park.

At first glance, one cannot help but think that their technical strength is strong. In fact, many of these companies are "capitalizing on big money" by setting up their offices in well-known units, and their "value" immediately doubles, turning the ugly duckling into a swan. Intentionally or unintentionally claiming that their company has strong technical strength is also easy to believe. There is a company located in a famous university that claims to have "X national technology and X major patents". After a customer purchased its equipment to repair the battery, they poured out the excess liquid. After charging and discharging tests, the battery capacity decreased. When asked about it, the customer replied that they had discarded the active ingredient. Even the active substance is unknown, and its level can be seen from this.

Lead acid battery repair technology emerged in China in the mid-1990s. Due to limited conditions, the equipment did not yet have pulse function. The repair of batteries was carried out using methods such as high current charging, overcharging, repeated charging and discharging, and water therapy. These repair methods could only repair slightly vulcanized batteries, and the effect was not ideal. They were not further promoted and soon disappeared.

The research on the application of pulse technology in scrapped lead-acid batteries appeared at the beginning of this century. This method has a significant effect on severely sulfurized batteries, but it is still in the research stage and has not been practically applied. The pulse lead-acid battery repair device entered the market promotion and appeared at the end of 2003. It was jointly developed by a company in Shandong and experts from Tsinghua University. Relevant information appeared on the Internet and relevant newspapers and magazines in 2004, that is, there is basically only one company that has repair equipment and repair fluid, and there are more than a dozen companies that only have repair fluid (powder) and no repair equipment.

In the first half of 2005, there was a gradual increase in relevant information, and in the second half of 2005, sharp smelling scammers began to emerge, taking advantage of people's lack of relevant knowledge to engage in rampant fraud. Two electric car chargers and one car charger competed to be sold as repair equipment for more than 4000 yuan. At present, the information about lead-acid battery repair technology online is not very abundant, and scammers cannot provide more knowledge about lead-acid battery repair. Those who have established websites also have incomplete and unprofessional information.

In 2006, with the gradual enrichment of information on lead-acid battery repair technology online, there were also more and more manufacturers involved in lead-acid battery repair. Those who had previously or had not engaged in this industry rushed out of the market, slacking off in troubled waters, and more and more. Most people claim to have been engaged in this industry for many years, and many even claim to be the "number one in China". The websites are becoming more and more "professional", and the deception is even stronger, making it difficult for newcomers who are new to this industry to distinguish between truth and falsehood.

How can novice travelers prevent being deceived

1、 The correct investment mindset.

Many people in this industry now have a speculative mentality, coupled with biased listening and believing, superstitious belief in some manufacturers' so-called "automatic repair, automatic stop, repair process is automatically completed during charging, no need to open the lid, no chemicals added, and the repair cost is zero". You can easily achieve great profits without putting in effort. It should be noted that 'no pie will fall from the sky', and no technology will be so simple.

Those who are easily deceived often hold a mentality of "getting rich suddenly" and also have a mentality of "hating the rich": they always hope to invest as little as possible and earn as much profit as possible. Usually, one's eyes are high but their hands are low. Seeing others succeed can easily lead to jealousy, and blindly believing in false advertising. Not wanting to invest or provide solid services, wanting to take shortcuts and make a fortune, often falling into the trap of others; To say that these people have a "hatred towards the rich" mentality means blindly believing in the low cost and high price of repair equipment that some people claim, and the manufacturer is seeking huge profits. Note that although the repair device also charges the battery, it has a considerable amount of technical content inside, and there are significant differences in cost and sales compared to ordinary chargers. It can be said that a high price does not necessarily mean a good repair device, but a low price is definitely a repair device with poor performance, and even a fake repair device or a real charger.

According to authoritative institutions, entrepreneurs with a "sudden wealth" mentality have a failure rate as high as 97.4%, and often end up being deceived. And successful entrepreneurs need at least 1.5 years to go from scratch to small achievements. Investors should rationally distinguish between "sudden wealth" and "getting rich", turn the desire for sudden wealth into the passion for getting rich, and realize their wealth dreams as soon as possible.

2、 Learn more about relevant knowledge

Don't be afraid to spend money, go and inspect in person. If necessary, bring batteries to verify the repair effect. For companies that cannot be inspected due to long distances, ask them to provide a list of customers who purchased the equipment, call them to inquire about the repair effect of their equipment, compare multiple aspects, and your relevant knowledge can be enriched to distinguish authenticity. It is not advisable to be deceived.

The authenticity of his technology (device) can be verified from the following aspects: (1) Whether the device is automatically repaired and stopped, and the repair process is automatically completed during charging without the need to open the cover. If so, his device is undoubtedly a charger, and the real repair device can only prompt and will not automatically stop. Furthermore, batteries tend to run out of water during use, so there is no need to open the cover and add liquid, as it is impossible to repair the battery. (2) Look at the output power (current) of the device: Devices with low power take longer to repair and the repair effect is not ideal. During normal use of the battery, using it for maintenance charging can extend its service life, but the effect is not ideal for repairing batteries that are close to being scrapped; For devices with high output power, increase the current appropriately during the repair process. If the battery temperature rises quickly, high current charging may be used. (3) The design life of lead-acid batteries is 3-5 years. Due to the formation of sulfate during use, they are often scrapped after 1-2 years of use. After repair, they can be used for another 1-2 years, and the effect is very good. Even if they claim to be the most advanced repair equipment, they should not be easily believed.

3、 Don't be misled by surface phenomena.

Some companies dare to claim to be China's well-known trademark patented products within less than a year of registration, while others have a plethora of real and fake honors, claiming to be "China's number one, industry-leading". Whether the company is located in a prestigious university or claims to be the number one in China, don't take it seriously. After careful consideration, make a decision. Don't be swayed by superficial appearances.
