Lead acid battery scrap the reasons can be divided into three types:
One is due to the recurring situation of water shortage in the overload or excessive shock caused by serious. Such as day and night driving a taxi, its batteries often without water also works on their float lead generators, causing fever Dell Inspiron 1300 battery short-circuit plate scrap battery bending cases of overcharging, the electrolyte is temperature, and the serious, such as boiling, like rolling up and down the electrolyte washed the plate, the powder will decrease with time, and pay the higher accumulation of lead powder, contour to the touch when you put the plate lead short-circuited, so that debris from the battery. Sulfuric acid solution with the traditional lead-acid batteries in vehicles in the process of its solution continuously washed plates, but also likely to cause plaque limed off, this is not a way to repair the end of battery life, the taxi on the scrap batteries are more than 90% can not repair.
The second battery is inferior product, refurbished battery, do not follow national standards developed by brand name batteries. The electrode of the battery and the solution are extremely bad in itself, let alone the quality of the new time will give more power, but it can not last long, it can be saved by scrapping.
The third situation is completely sealed lead acid VGP-BPL11 battery, this battery isolation sandwiched between two electrode plates, such as wool felt and others who are full absorption of electrolytes. The battery is not affected by the effects of plaque reduction, which scrapped the reason is that most part of the cards often “irreversible cure” phenomenon caused by the panel that produced crystals of sulphate White lead to the plate The effective area smaller and smaller, so that smaller and smaller battery capacity, meaning that the original charge of a battery can run 40 km bike, and not later work only 20 km, the last 1 km is also Pao Bule, just discarded.
To lead plates of the battery acid crystals produced PBS reasons are manifold, the longest is to see a long-term investment without the battery, such as car manufacturers begin shipping the long-term n ‘ have not sold a car parked in the garage, time for a long time, and sell Dabu Zhao fire when the car battery wrong, because the board has a very large surface to generate crystals of PBS. If the owner of the private car of a long business trip abroad, they will find car Dabu Zhao responded, he did not budge. Another example is a serious over-discharge, but it will also lead plates of the battery acid produces large surface crystals of lead sulfide have been rejected as forgetting to turn off the lights, open all night on the motorcycle battery is fatal. Anatomical These are all sealed lead-acid VGP-BPS13/S batteries, you can see a crystal of sulphate of lead white plates have two interrelated, pull Abdullah not open at that time, both originals volts per cell (12-volt battery is composed of six cells in series) is now close to zero volts.
No matter if it is sealed or unsealed batteries, those who have been rejected for the reasons above, and be able to recover. The pulse of modern technology allows this “irreversible cure” phenomenon a reversible phenomenon. The author in 1999 made such a device, made many years of trials, the effects were very good, the anatomy has been repaired Fully sealed lead acid batteries, you can see a board very white crystals of lead sulfate have virtually disappeared, repair before the VGP-BPS10A/B battery voltage has recovered to nearly normal voltage zero-volt battery, this time dependent and discharge according to the conventional approach to its charge and discharge, and found that its capacity has been restored to 90% or over 100%.
According to U.S. sources, however, using this pulse technique for the repair of batteries, their useful life can be prolonged by more than five times, I have not had this experience and the quality of our internal battery failing this, but I would like to formally Plant production of batteries for electric bicycles, repairs will double its life expectancy is increased.
To prolong the life of lead acid batteries in 1999, I also developed a passive protection device, which is connected to both ends of the stack by stack electronics, it is low power. Since each crystal before it is cited as a core because it does not it also can not form crystals. The principle of electronic products is to use the pulse continuously added to the same committee, so it can not form nuclei, which can produce crystals of sulphate of lead white, speak a simple language can be considered the pulse of continuous washing of the plates so that the battery can be given sufficient power. Use of this protector of the owners feel they have enough power. In the north, due to the cold in the morning cars are often Dabu fire Zhao, whether such protective devices used, can be avoided outside of this evil.
