7. Battery life determined by the number of repeated charge and discharge, it should try to avoid battery power than when charging, it will shorten the laptop battery life. Phone off for more than 7 days, should be first mobile phone battery is fully discharged, adequate electricity and then use.

8. Mobile phone battery self-discharge exist, not when the nickel-metal hydride batteries a day by about 1% of the remaining capacity of discharge, lithium batteries a day by 0.2% ~ 0.3% discharge. In charging the battery, try to use a dedicated outlet, do not share household electrical appliances such as charger and TV socket.

9. Although the mobile phone network coverage within the region, but the phone off when Dell laptop battery charging the phone is no longer acceptable and the call. At this point, you can use the phone’s not connected to the transfer of functions transferred to the phone side of the fixed phone in order to prevent loss of calls, this method is not for the mobile phone network coverage in weak signal area, or is temporarily unable to connect when you apply.

10. Do not expose the battery under high temperature or cold, like a dog day, and not turning the phone on the car, and withstood the scorching sun exposure; or get air-conditioned room, on the air conditioning blowing straight places. When charging, the battery a little heat is normal, but can not be Jinshou high temperature “suffering.” To avoid this from happening, it is best carried out at room temperature for Dell Studio 1537 battery charging, and do not cover anything on the phone.

11. Nickel-cadmium (N iCd) must ensure that the battery before the battery completely without electricity, and then charge must ensure that the battery fully charged.

12. If the phone battery to place too long without use, it is best to phone the maintenance department to apply to the batteries for a living dealing with, you can own with a constant voltage DC device, adjusting the voltage of 5 ~ 6V, current 500 ~ 600mA reverse Connect the battery. Note that the liberalization of touch, most can be repeated three times, after such treatment, re-use original charger to “adjustment” Dell XPS M1330 battery charge.

13. The longer the charge when he is not good, for not protecting the circuit full battery charge should be stopped immediately, otherwise the battery overheating due to heat or impact performance.

If users want to prolong the battery’s effective use of time, in addition to the quality of the charger should have guarantees, are essential for the proper charging techniques, because the poor quality of the charger or charging the wrong methods will affect the battery life and Dell Studio 1536 battery cycle life The following is the charging techniques:

1. The battery factory, manufacturers have carried out active treatment, and conduct a pre-charging, the batteries have more than electricity, a friend of mine said that the battery charge in accordance with the time period of adjustment, standby is still a serious shortage, if the battery is indeed the genuine battery, then this kind cases, an adjustment period should be extended a further 3 to 5 times fully charge and discharge.

2. If the new cell phone to buy a lithium-ion battery, then the first 3 to 5 times charge commonly referred to as an adjustment period, more than 14 hours should be sufficient to ensure the full activation of the lithium-ion activity. Lithium-ion battery without memory effect, but a strong inert, should be given to fully activated in order to guarantee Dell Studio 1555 battery that used to achieve the best performance.

3. Some automated intelligent rapid charger when the lights change direction, only that was full of 90%. Charger will automatically change with the slow charging the battery is full. Is best used after the battery is full, otherwise it will shorten the usage time.

4. Charging, lithium batteries do not need special discharge, discharge improper battery will be damaged. Charging as far as possible in order to slow Chong Chongdian to reduce the fast charge mode; time should not exceed 24 hours. After three to five times the battery fully charge and discharge cycles of its Dell Vostro 1710 battery internal chemicals will be all “activation” to achieve best results.

5. Use the original or the reputation of a good brand of chargers, lithium batteries use lithium laptop battery charger dedicated, and follow the instructions, otherwise it will damage the battery or even dangerous.

6. There are many users, often in charge when the phone open, in fact, it will hurt the mobile phone life very easily, because in the charging process, the cell phone circuit boards will be fever, at this time if there are external phone, you may create instantaneous return current, the phone’s internal parts damage.

Introduction of waste battery pollute the environment

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.
