If you randomly discard used batteries cell laptop battery laptop will have a direct pollution to the soil and water resources, and a mobile laptop battery may be severely polluted 60 tons of water, this figure startling and shocking. To see this information, how would you deal with it in the hands of discarded cell laptop batteries?In fact, scrap mobile laptops and batteries contain a valuable resource, recycling and reuse can bring significant economic value. In order to promote recycling of used mobile laptops and batteries re-use, from the communications operators to handset manufacturers and then to the professional mobile laptop, battery dismantling business, the entire mobile laptop industry chain are all in action.
At present, the domestic carriers, represented by China Mobile launched a “Green Box” of environmental programs in the country at about 1,000 self-managed business hall and mobile laptop manufacturer, Motorola, Nokia, the 150 sales centers and long-term maintenance center set up a “Green Box”, specializes in collecting discarded laptops and accessories. China Mobile in 2008 through the “Green Box” environmental protection programs discarded mobile laptops and accessories were recovered 1.35 million, of which 90% of mobile ThinkPad T41 laptop batteries.

Scrap mobile laptop battery inside of cobalt and nickel
Professional battery recycling and reuse businesses Grammy successfully resolved a small used batteries of high-tech, economic-based recovery.
“Waste battery is a treasure, which contains a large number of rare metals, rare metals or even refined ore as a resource can be an alternative to similar products.” Shenzhen Grammy’s technology standards and property manager, said Han Hong-Tao case.
Metals in the cobalt, nickel, is also an important raw material production of high-performance batteries. Spent batteries is rich in cobalt, nickel, but its ThinkPad R51 extraction technology is extremely complex, previously only found in Canada and a very few countries. In 2003, the Grammy’s and Japan’s Tokyo University, China, Central South University, tackled extracted from the used batteries of cobalt, nickel, technical difficulties, and has become the only master of the ThinkPad T42 sophisticated technology, business, successfully resolving a small scrap batteries high-tech, economic-based recovery.
At present, the Grammy is a circular economy pilot units, but also to China’s sole waste batteries and battery recycling of waste as raw material the size of ultra-fine powder of cobalt and nickel businesses. Grammy recycling of used batteries There are several varieties: one battery, mainly zinc-manganese dry battery; secondary batteries, mainly nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries. As the used batteries collected separately for recycling the sponsor, Green the United States has in Shenzhen, Wuhan, Guangzhou, Zhongshan and other 12 cities launched the classification of waste batteries recycling activities, the cumulative installation of 15,000 recycling bins, the annual collection of nearly 3,000 tons of used ThinkPad T43 batteries.
Past five years, Grammy has gone through the pilot plant, small-scale factory to the cycle of industrial park construction, has completed an area of 420 acres, garden-waste resources to deal with the R & D and production centers, and two used batteries and electronic waste recycling the use of plants, the annual volume of waste disposal of waste cobalt and nickel, used batteries, electronic waste and other types of waste volume of 30,000 tons, 2,000 tons of the formation of ultrafine cobalt and nickel powder, nickel alloys and other high-tech products, recycling capacity.
As of October 2008, Greene Co and Ni in the United States deal with the total 50,000 tons of waste, recycling 4,000 tons of heavy metals, saving more than 300 million tons of raw ore to reduce the more than 21 cubic meters of water and 29 square kilometers of soil pollution, carbon dioxide emissions of more than 3100 tons, saving 72,000 tons of ThinkPad R50 standard coal.

Error: the first charge must be charged enough for 12 hours
This for those early no batteries control circuit of the machine is applicable nimh batteries, but for now, an intelligent control circuit of the laptop battery charge is a joke, when the notebook computer batteries charging current with, will be cut off, even if you continue to filling 120 hours, the state has also won’t have any change, generally speaking, even the slowest charging machine, 6 hours, completely filled with “charge” is just wasting your time. But when the new machine is to get the power should be shining recharging.

Error: battery needs regular correction, once a month were completely.
For the strong memory effects, this is the nimh batteries must work, but for lithium batteries, this cycle is too often, though not completely eliminate lithium batteries, but has memory effects greatly abate the memory effect, if you use the battery is frequent, so you should be discharged to a lower (about 10-15%), but if the discharge recharging the machine can’t open (0-1), is to have greater damage of lithium batteries, generally speaking the depth discharge every 2 months to do this operation. If you rarely used batteries, so just once every 3 months of this operation.

Four: calibration error can ascend battery capacity
When the battery is called correction, the actual capacity and control circuit of the record for different capacity battery charging and discharging operations, a depth to control circuit, and make record close to the actual situation of the battery, the battery is an expression of the real capacity and non-ascending capacity, here is the key factor of the battery, the battery actual capacity than the actual capacity, if the control circuit of the record, the capacity of the battery capacity calibration can look, if increase battery capacity than the actual control circuit of the record low of capacity, correction will reduce battery capacity, it also seems to correction is many people argue, please remember that the real correction is a battery capacity, eliminate battery and deviation between the control circuit and the capacity is displayed as will increase or decrease, this is the state battery itself instead of your calibration of the decision. Probably because of the depth of the battery when correcting, instead of discharge capacity drops greatly.

Myth 5.not: compatible charger can also use
The notebook computer power far outweigh the mobile phone, in the most extreme cases, power supply for battery and to cope with the machine run at full speed for power supply, notebook computer is not compatible with each type of battery charger, because of voltage, current, or interface are different, can be in a variety of universal notebook “compatible charger” probably even more expensive than the original charger, even the same interface, if the voltage and current under the nominal value, machine working at the machine when battery may be unable to gain enough for the battery charging electric current, the damage is great. If the voltage and current under nominal values, even find too many fundamental unbootable or can boot cannot charge, so choose to choose the best of power and the same, original couldn’t find words, please pay attention to the voltage and current must conform to the machine, with the nominal values of different products, but generally the same interface voltages and currents may be different, it must pay attention!

Error: full battery electric (or need) save electric light
Both full or light, it is incorrect, light electricity for long-term preservation will lose activity core, even control circuit protection self-locking and can’t use, full of electricity for long-term preservation will bring safe hidden trouble, the most ideal method is about 40% to discharge and preservation, lithium battery moist and fear, therefore, should be high in cool and dry place, but may not be too low temperature, otherwise will greatly reduce the capacity of about 20 degrees Celsius temperature preservation is the ideal.

Seven: the battery and error can still change core
Many of the battery is such a change of deadly, manufacturers seem expected someone will do so, many brand notebook batteries design are locking function, once the core from control circuit, circuit entered self-locking condition, only use a specific method can solve, before this control circuit will not work, namely battery core notebook batteries, equivalent to scrap the dry batteries can not change, if you want to change, please remember to find core of battery maintenance companies to settle in fencing, his efforts, the void after failure of depression and depressed is the worst.

After eight: 99 misunderstanding, continue to less than 100% charged rechargeable would explode
The laptop battery explosion is almost no chance at a high fever, caused by melting, but rarely shell caused by fire, released a few accident is due to the fact that the production process, when in use to cause a short-circuit, even the most short circuit will be in the battery protection circuit disconnected from greater harm circuit, unless it is in the core short-circuit protection circuit before. It is so many things in the mobile phone battery, ultimately or the quality problem, mobile phones have plenty of inferior assembly, notebook computer batteries almost never such a battery, because no sale which type of ownership is compatible to produce batteries.
