AA Carbon battery.Technical development of battery repair equipment

　　When lead-acid batteries are in use, their plates will inevitably undergo vulcanization, just like human aging. When the surrounding environment is closer to the optimal working environment of the battery, its life will be longer. Batteries manufactured by manufacturers are designed according to ideal environments, and their working life can generally reach more than 8-10 years (backup batteries can last more than 15 years). But the actual service years are often less than 1/3. The main reason is that there is a huge gap between the actual working environment and the ideal working environment. If the indicators of the charger are inaccurate, charging voltage that is too high will accelerate water loss (causing vulcanization of the plates), charging voltage that is too low will also cause vulcanization, and frequent failure to charge in time will directly cause vulcanization of the plates. Shorten the battery life. Frequent high current discharge, severe vibration, etc. will also shorten the battery life.

　　Among the above-mentioned factors that affect battery life, battery plate vulcanization is the most common and obvious factor. Many people do not know how much the correct maintenance of batteries is related to its service life. Like people, if they do not eat, their lifespan is only If you are often hungry and full for a few days, you may be overworked and you will die in your thirties or forties. But if you live and work regularly and have medical insurance (if there is no hospital, I believe that the average life span of a person will not be long). will exceed the current average) and live a long time (80-120 years old).

　　The battery is alive. Even if you purchase a new battery, it will not be used for a day, but if it is not charged for a few months, it will die (that is, it cannot be charged and discharged). If the charge and discharge management is not in place, its lifespan will generally end in 1-2 years. , and the lifespan may be very long if the maintenance is in place, but to be really long, you must have "doctors and equipment", that is, professional battery maintenance personnel and battery maintenance equipment. Among the battery maintenance equipment, the average user only has a discharge machine (many people still use it poorly). The repair instrument is a new type of battery maintenance equipment that has only appeared in recent years. It is like a scalpel and penicillin for treating diseases. If the battery repair instrument is used correctly, This can save the life of most batteries and extend the service life of the batteries.

　　Almost all the items you see, even if they are old, still have use value, such as stools, clothes, houses, etc. Therefore, there are second-hand markets everywhere. However, there is no second-hand market for lead-acid batteries worth more than 500 billion yuan every year! The reasons are: first, the battery life is short, and second, units buy more. But this is not the fundamental reason. The fundamental reason is people's concept: used batteries no longer have the ability to store electricity, so of course they are "waste"! Second, there is a general lack of second-hand battery brokers!

　　The performance of a battery is not like other products. You can basically tell at a glance whether it has reuse value. There are many senior technicians who manufacture lead-acid batteries. Their focus is on the service life and price under standard usage environments, while users basically have no idea. Too high-level professional and technical personnel. For a long time, only a few technicians have been using and maintaining batteries carefully, and they are indifferent. Even if they have some experience, it is difficult to carry out in-depth work. Less efforts have been made in developing and manufacturing professional battery maintenance equipment. The common battery-related equipment provided by users is mainly a charger. Some units are equipped with dischargers, but they are rarely used. When the battery cannot meet the usage requirements, it is treated as scrapped. . Those who propose scrapping are usually people with certain battery experience. Others often don't understand and are unable to check again, so they can only follow the approval.

　　When purchasing a new battery, since there are no second-hand batteries to choose from, you can only buy brand-new batteries. Users who buy new batteries basically do not test the battery capacity. The capacity is given by the manufacturer's nominal parameters and is trustworthy (the manufacturer does not dare to cheat, as it is easily discovered).

　　With the development of technology, used lead-acid batteries are not necessarily "waste" in today's view. Of course, the waste referred to here means that they have no ability to store electricity. Many used batteries can recover most of their capacity after being repaired by repair equipment. Since battery repair is a new industry and requires trained personnel to use professional repair equipment, there are very few professional brokers who can provide second-hand batteries.

　　Users generally do not need to verify the capacity of second-hand batteries at the time, but they need the seller to provide trustworthy data. Due to the huge price gap, users may start to use them with caution. Brokers can use the second-hand battery network to develop customers across the country. After gradual development, the first batch of brokers will have a group of large users.
