How to repair the old laptop battery capacity?

Source: 2020 - 04 - 14 'hits: time to repair the old laptop notebook battery capacity and the use time of the biggest feature is the mobility, but if the battery is not to force, mobility has become 'talk'. However, the old capital used for a long time, the battery life significantly reduced, the original time more than 4 hours of battery life, may now be only 1 hour, although you can change the battery, but after all, spend money, in fact, with the help of the battery monitoring and correction software, you can repair it for free battery life. In order to restore the battery life, the author use the 'ymon battery tools, easy to use. First of all, download the battery, and to ensure a full charge. Because software under XP work better, so suggest that Windows 7 users to switch to XP system, to play, after all, battery life, it's worth taking the time. Connect the power adapter, run the 'power options in the control panel, and then under the' battery solutions' choice 'biggest battery model, at the same time will use the battery under the' three option is set to 'never', after confirmation, unplug the power adapter, and then click 'battery information' icon, the software will display all the information of the battery. When you find the battery capacity is decreased obviously, such as the design of the 6300 mah capacity and the current capacity of less than 3000 mah, suggest to repair the battery discharge, but if the current display capacity of more than 5000 mah, you might consider taking some time to repair. Click on 'start' button to discharge test. At this point, the power decline curve can see in the coordinates, among them ordinate said the current battery remaining power percentage, order of battery life. The information on the left shows the battery discharge rate can be used in the maximum time of saturation. So, turn on the laptop discharge completely shut down until the consumption, then the battery again, repeat 3 times or more of the discharge process, through the test, after three times discharge test, the author's old laptop battery capacity increased significantly, from the original 690 milliampere ( About 20 minutes) , increasing to 2287 mah ( 3600 mah capacity for original , battery life is 2 hours, very happy. Lithium battery as a kind of clean energy, its application is becoming more common, but the production process of environmental pollution is becoming more and more get the attention of people. The battery waste water treatment at home and abroad mainly focused on the removal of heavy metals, and the battery production process of organic wastewater treatment, especially the waste water containing ester, has not been reported. A factory of north China in the process of production of lithium-ion batteries, ester wastewater discharge about 15 t every day, which mainly contains small molecule esters. The wastewater organic matter concentration is higher, the pH value of 3 - 5, belongs to the acid waste water, BOD/COD is 0. 05 - 0. 12, not suitable for biological treatment directly. According to the requirements of industrial wastewater treatment and plant geography environment, the characteristics of the wastewater by activated carbon adsorption pretreatment, can reduce the toxic pollutants in the process of subsequent processing of the inhibitory effect of microorganism, guarantee the stable operation of biological system. In addition, still can reduce wastewater biochemical treatment of hydraulic retention time, greatly reduce the cost of investment and running cost J, activated carbon adsorption saturation can be reused after regeneration. Traditional activated carbon regeneration methods mainly include thermal regeneration, solvent regeneration and rebirth. Thermal regeneration is one of the important forms of activated carbon regeneration. The regeneration is L3J based on the traditional hot regeneration technology developed a kind of effective regeneration. Compared with the traditional method of thermal regeneration, regeneration time is short, high regeneration efficiency, low loss, low energy consumption advantages of auricle. Is adopted in this paper, on the basis of the activated carbon adsorption, adsorption time, initial pH value of wastewater and the influence of the content of activated carbon adsorption and microwave irradiation regeneration of active carbon adsorption method, microwave radiation time, microwave power on the activated carbon regeneration efficiency, and the influence of the carbon loss rate, under the condition of appropriate repeated regeneration.
