According to dell laptop battery expert testing, a button dell laptop battery to 600,000 liters of water pollution; One rotten in the battery, the one square meters of land can lose value. Experts pointed out that the used batteries trash mixed with the treatment of life, the battery after the decay, in which the mercury, cadmium, lead, nickel and other heavy metals will pollute the water body stripping and soil, and through the food chain, ultimately endangering human health. People if mercury poisoning may cause central nervous system disease, the mortality rate as high as 40%; cadmium level was set at IA carcinogens.
The biggest threat to the natural environment of five substances, battery contains three types: mercury, lead, cadmium. dell inspiron 500m battery, dell inspiron 510m battery, dell inspiron 600m battery, dell latitude d500 battery .
Mercury: what we commonly known as “mercury”, with carcinogens. Mercury and mercury compounds are toxic, the scientists found that mercury has obvious neurotoxicity, in addition to the endocrine system, immune system also has adverse effects on children more Toshiba battery vulnerable.
Cadmium: in the human body can easily cause chronic poisoning is a lot of heavy metal toxicity, the main diseases are emphysema, bone softening, dell latitude d510 battery anemia, is likely to paralyze the body. And lead the most difficult to enter the human body excretion, which interfere with renal function, reproductive function. Japan shocked the world “pain” is caused by cadmium. Cadmium contaminated mine wastewater and river water the soil, grain, forage, enter the body through the food chain and slowly accumulate in the kidneys and bones. Replace calcium in bone, so that a serious softening of bones, bones; cadmium can cause stomach dirty dysfunction, interference with the human body and biological in vivo zinc enzyme systems to reduce zinc than cadmium, and lead to hypertension increased. Cadmium toxicity are potential. Even if the concentration of cadmium in drinking water as low as 0.1 mg / l, but also in humans (especially women) tissue accumulation, the incubation period of up to ten to thirty years, and difficult to detect early. Data indicate that the human body biological half-life of cadmium in 20 ~ 40 years. Cadmium on human tissues and organs of the poison is multifaceted, and treatment IBM battery extremely difficult. Therefore, the countries of the industrial emissions of “three wastes” in cadmium have been very stringent requirements. Japan also provides that the cadmium content of rice more than 1 mg / kg is “cadmium rice”, the prohibition of consumption. Because of dell latitude d520 battery, dell latitude d600 battery cadmium compounds with varying degrees of toxicity, by any means from the waste water in addition to cadmium, only to change its existence in any way separated from the wastewater, in addition, there can only change its ways and the location of the transfer of its existence, and should not eliminate its toxicity. Therefore, cadmium wastewater treatment should be combined with the recovery and utilization.
Nickel: a carcinogen, to aquatic organisms has dell 312-0068 obvious hazards, nickel salts can cause allergic dermatitis;
Lead: lead to anemia, nerve dysfunction, kidney damage, even greater harm to children.
At present, the main laptop dell 1×793 battery has lithium batteries and two Ni-MH ThinkPad T60 battery . Li-ion battery has become the mainstream standard in laptop batteries, nickel metal hydride batteries the phasing out of here and I am not about nickel-metal hydride battery routine maintenance. Lithium batteries have the same memory capacity of electric capacity, but compared to nickel-hydrogen batteries are much smaller memory capacity, and the use of special methods of memory can be eliminated. Large capacity lithium battery, and generally about 4000mAh, charging a comparatively short time. However, the rechargeable lithium dell inspiron 1100 battery, dell inspiron 5100 battery to support the number of relatively small, generally charging 400 ~ 700.
To learn more about the basic characteristics of lithium batteries, following on to see how the process of maintenance in the use of battery:
1: to minimize the use of dell 6t473 battery
I suggest that it can not find the power to use the battery. Li-ion Acer laptop battery only has about 400 charge life, frequent use of battery-job increase in the number of battery charging, if the average charge for two days time, your battery for more than a year on basic scrapped.
2: do not use power supply battery
Laptop in the use of alternating current job as far as possible, remove the battery to avoid battery discharge and recharge often. Lithium batteries self discharge an average of 0.2 percent per day, generally detected as long as the laptop battery charge on the discontent, even the high-quality notebook battery discharge in the case of a few per cent of the start of battery charging, the battery discharge day and charging a lot of times, greatly reducing the dell inspiron 630m battery, dell inspiron 640m battery life.
3: New batteries need to activate the operation
New apple batteries should be 1 ~ 2% with electricity, if electricity is full, it is not a new battery. After the computer out of the box not to an external AC power, let the machine run out of battery residual capacity, then a one-time the battery is full, then all one-time discharge, the final one-time full of batteries, such batteries can be fully stimulated activity, greatly enhance the capacity of the battery charged.
4: To improve the capacity of the dell y9943, dell rc107 battery memory
If battery life is too long, have a certain low-charged memory, power supply capacity to greatly reduce, you can use the method to improve the battery discharge performance. As follows: to enter the computer BIOS turn off power management features to prevent laptop with low-voltage protection, unplug the AC power, only the use of battery-powered, and then boot the battery completely exhausted, the last full battery.
Although the laptop, but also required a good job to protect the battery. We use every day the process of laptop battery should be used to develop good habits, to extend laptop battery life, so that we really can use the MacBook Pro 15 inch battery anytime, anywhere, casually entertainment and work.
