Three reasons leading to the scrap of lead-acid batteries

Lead-acid battery repair and protection details. Lead-acid battery scrap can be roughly divided into three reasons: one is because it is often overcharged or over-discharged in the case of water shortage. For example, if a rented car runs day and night, its battery often still works in the absence of water. During the movement, the generator will float, causing the battery to heat up, and the battery will be scrapped due to the tortuous short circuit of the electrode plates. When the battery is overcharged, the electrolyte heats up, and the serious ones will like the same cheers, roll up and down the electrolyte to wash away, and the lead powder will fall. For a long time, the lead powder will drop higher and higher, such as high enough contact. When the lead plate is short-circuited, the battery is scrapped. Traditional lead-acid batteries use sulfuric acid solution to continuously wash the steel plate during the driving of the vehicle, and lead powder on the steel plate is easy to fall off. This kind of used battery is irreparable, and more than 90% of the used battery comes from leased vehicles. Repaired. The second is counterfeit product batteries, refurbished batteries, and non-brand batteries that are not processed according to national standards. The plates and solutions of this battery are extremely poor, and its quality is not worth mentioning. It can give some electricity in the new time, but it can't last for long by itself, so that it can't be stored when it is scrapped. The third type is a completely sealed lead-acid battery. A barrier plate, such as felt, is sandwiched between two electrodes and filled with electrolyte. The battery plate will not drop, and the reason for scrapping is often caused by the irreversible phenomenon of the vulcanized plate. It is a white lead sulfate crystal plate. The effective area of u200bu200bthe plate is getting smaller and smaller, so the battery capacity is getting smaller and smaller. The initial accusation that the electric bicycle runs 40 kilometers, is the result of an electric bicycle can only run 20 kilometers, 1 kilometers, after all, can not run, can only be discarded. There are many reasons for the crystallization of lead sulfide in lead-acid battery plates. The longest time I have seen batteries have been used for a long time, such as cars in the new factory of an automobile factory, are not sold for a long time, and they are parked in the garage for a long time. Selling a car will not catch fire. When the battery is broken, the reason is that large lead sulfide crystals appear on the board. Suppose that the owner of a private car has been on a business trip for a long time. When he comes back, he will find that the car cannot be started or moved. Another example is severe over-discharge, which will cause large areas of lead sulfide to crystallize lead-acid battery panels and be scrapped. For example, if you forget to turn off the light and leave it on all night, the battery of the motorcycle is dead. Dissecting these completely sealed lead-acid batteries, it can be seen that the white lead sulfate crystals glued the two plates tightly together, and they cannot be separated. These two volts are in each unit (a 12-volt battery series includes six cells). ) Is now close to zero volts. Batteries, whether sealed or not, can be recycled if they are scrapped for the reasons mentioned above. Modern pulse technology can turn this irreversible vulcanization into a reversible phenomenon. On March 15, 2005, a new generation of battery protection series products developed by German engineer Bingle and proud chipower engineer Ray after 6 months: battery calibration equipment, more than half a year of practical testing, the effect is very good, fully sealed lead-acid battery In the anatomical repair, you can see that the white plate lead sulfate crystals have basically disappeared, and the battery voltage is close to zero volts. The battery voltage is restored to the normal battery voltage before the repair. At this time, it will be charged and discharged according to the conventional charging and discharging method, and then it will be Found that its capacity has been restored to 90%, and 100%. According to the report, the pulse technology battery is modified according to the material, and the body can be extended by more than five times. We have never done this test, and the quality of our domestic battery cannot have this standard, but I think the factory processes the electric bicycle battery on a regular basis, and it will definitely be repaired. Will extend its life span twice. Disclaimer: Some pictures and content of the articles published on this site are from the Internet. If there is any infringement, please contact to delete.
