First, A battery made up of: battery, rechargeable battery, composition: zinc skin (metal), carbon rod, mercury, sulfuric acid compounds, copper cap; battery with lead-based compounds. For example: 1, the composition of waste zinc-manganese battery, weighing 70 grams, of which carbon rod 5.2 grams, 7.0 grams of zinc skin, manganese powder 25 grams, 0.5 gram of copper cap, the other 32 grams Dell Latitude D410 battery.

Second, the danger of used battery: hazards of waste battery mainly concentrated in a small amount of heavy metals contained in them, such as lead, mercury, cadmium. These toxic substances enter the body through various means, long-term savings and difficult to remove, damage to the nervous system, hematopoietic function and bone, and even can cause cancer. Lead: nervous system (nerve weakness, numbness of hand-foot), digestive system (dyspepsia, abdominal cramps), blood poisoning and other diseases. Mercury: Mental state of change is one of the major symptoms of Dell Vostro A840 battery mercury poisoning. Pulse speed, muscle vibration, mouth and digestive system diseases. Cadmium, manganese: The main harm the nervous system. 3, used battery polluting ways: the material composition of these battery during use, is sealed inside the battery shell and does not affect the environment. However, after a long-term mechanical wear and corrosion, making the internal leakage of Dell Studio 1737 battery heavy metals and acid-base and so on out into the soil or water, it will through a variety of ways to enter the human food chain. Process summarized as follows: Pool microbial food crops, animals, circulating dust deposition of human neurological disease.

Third, Other water sources, bio-digestion of plant food intake of heavy metals from the environment can be through the food chain biomagnification, grade by grade in the higher organisms tens of thousands of land-rich product, and then enter the human body through food, and in some organs savings cause chronic poisoning. Japan’s water (one plus Wu) disease is a typical case of Dell Vostro 1520 battery mercury poisoning. Fourth, the performance of used battery against the other: the world’s main municipal solid waste sanitary landfill, composting and incineration of three ways, mixed with garbage of used battery in these three roles in the process of pollution is reflected in: landfill: waste the role of the battery of heavy metal pollution of water bodies through leachate and soil. Incineration: waste battery in high temperature, corrosive, some heavy metals in the incinerator fly ash in volatile, causing atmospheric pollution; incineration bottom heavy metal accumulation, to the ash generated by pollution. Composting: scrap battery high content of heavy metals, resulting in lower quality compost. Re-use: general use of reflective fire metallurgy, process while easy to master, but the Dell Inspiron E1705 battery recovery rate is only 82%, the rest of the lead in the form of gas and dust appear at the same time refining the process of sulfur dioxide into the air, causing secondary pollution, direct endanger the health of workers operate.

18. Q: How do I calculate my new battery can be used on the computer a few hours?

A: Generally a battery, and the computer has a direct relationship between the consumption of Dell XPS M1330 battery power. For example, a 10.4-inch screen computers, working with low-power CPU, then the normal use of this computer every hour of power consumed by the 10WH-12WH between the battery can provide power output calculated as follows: S said voltage multiplied by the nominal capacity, equivalent to the battery can provide the total power output. For example, for a nominal 11.1V, 4400mAh notebook battery can provide power output 48.8WH, then the battery in this 10.4-inch computer station can be provided during normal working hours of about 4 hours. The power consumed by the use of computers with the use of computers also have a direct relationship between the state, if it is playing games or watching DVD, the computer is running at full speed the power consumed by the concomitant increase Dell XPS M1530 battery, then the battery life will be with the to reduce it.

19. Q: How should the battery be stored?

Answer: (1) If the laptop battery performance to maintain stability, we must always be an independent application of the battery to work. If the form of closed-circuit the battery, then stored for a long time, the battery will be damaged.

(2) a month or more for a long time do not use the battery, I suggest remove the battery from the computer, its 60% -80% charge and stored in dry, cool and clean place. If the time is not the case of Dell Inspiron 1525 battery, the battery’s capacity will ultimately damage is lost. Therefore, it is necessary to save some time after charging the battery. Of course, if you are able to use once a month, it will be better able to ensure that the battery storage.

20. Q: what should be done to make the battery safe?

(1) to avoid the water cause the battery to short-circuit the battery, short circuit will cause serious damage to the battery;

(2) to avoid the drop, knock the battery, which could lead to batteries exposed within the corrosive substances;

(3) to avoid the battery exposure to heat, humidity and more rainfall than places;

(4) batteries must be away from fire or other extreme heat source, the battery exposed to extreme heat sources may cause an Dell XPS M1730 battery explosion;

(5) Avoid placing the battery under the sun exposure;

( 6) No open, repair or tamper with batteries. The Dell Inspiron E1705 battery will overheat and burn. Corrosive alkaline solution or other electrolyte leakage can cause fire or injury.

(7) Do not use sharp objects piercing the battery.
