The proper use of laptop can extend laptop battery life (part 1)

October 27, 2009 9:05 pm

Laptop battery life is indeed a headache issue to us, although we can not make any changes to laptop battery, but we can improve the utility by changing the habits of notebook using, so that battery life is lengthened. These more than 10 tips below is the practical method prepared for notebook users to extend battery life.

1. Defrag regularly

Defragging your hard drive that allows to work faster, make the hard disk defrag on a regular basis to maintain effective state, of course, defrag when using an external power supply. The disk response speed become quicker and working time become shorter, it will certainly reduce the power consumption to extend laptop battery life.

2. To reduce the screen brightness

Most of the laptop screen brightness can be adjusted, there are some even can reduce the CPU’s operating frequency. When using the battery to reduce these parameters can be more effective to extend battery life.

3. Turn off background programs

There are some programs running in the background, although not directly see these programs running, but all consume CPU processing power, of course, consume battery power. The best way is to turn off all unnecessary background processes in order to prolong battery life.

4. Reduce the peripheral equipment

USB devices (including your mouse), Wi-Fi wireless connections are able to consume battery power, when the equipment is not in use, the best way is to pull down or masked. There are some equipment, such as the iPod will begin to charge when connecting with the computer,  be careful not to do it when using the battery-powered laptop .

5. Adding more memory

More memory means that notebooks do not be so dependent on virtual memory. Virtual memory is built on the hard drive, obviously access memory power consumption is lower, so more read the memory rather than the hard drive, this can reduce power consumption. However, adding memory also can trigger the issue of energy consumption, so the computer often use virtual memory, the most the time to consider adding memory.

6. Donot use drive too much

Although the hard drive power consumption relatively larger, but in fact  the energy consumption of drive is more in the eyes. Even when not in use, CD-ROM is still rotate, consume energy. If you can find a suitable virtual CD-ROM files, through a virtual drive to read, obviously much less power consumption.

7. To keep the interface clean

We proposed here, every few months to clean up laptop battery metal interface, you can wipe by a cloth soiled with alcohol. This can ensure that the battery inside the battery can be more effectively transmitted to the various components to consume.

8. Take good care of the battery

Take good care of the battery is not to shelved, but regular check it out. Do not let the battery fully charged do nothing for a long, long time. Once charged the battery power, you should at least fully used once every two or three weeks. Of course, do not let your battery completely consume the electricity, it is the way to deal with the old battery memory effect.

Scientists Found Eco-friendly Bacteria Batteries Powered by Dirt

October 27, 2009 9:03 pm

Harvard scientists have found a solution that could light up homes of some 500 million people living in sub-Saharan Africa. They have created microbial fuel cell (MFC) batteries that derive power from naturally occurring bacteria in soil.

These eco-friendly batteries come in the form of a layer of sand that acts as an ion barrier, mud with manure, salt water, which acts as an electrolyte, a five-pound bucket that carries a graphite-cloth anode and chicken wire cathode. The energy that is released out of the bucket could power a few LED lights and even small electronics.

Lebone is the company created by the Harvard team. They buried 100 units in dirt that will provide energy for several months to Namibian families who lack access to electric energy. When watered to keep the microbes munching, the buried cells can produce power for months.

“Rural Africans are used to getting resources out of the ground,” says team member Aviva Presser Aiden, a doctoral student in applied math and genomics at the Broad Institute of MIT and Harvard. “We want to tap that familiarity.” This system is ideal for developing nations or poor countries because the MFC batteries are eco-friendly, easily made and cheap to produce.

Laptop Battery Knowledge Q & A

October 26, 2009 8:58 pm

Q1: usually said 3-cell, 6-cell battery refers to what? And does it relate to battery capacity?

A: 3-cell, 6-cell is the number of cells in the batteries. The more cells the greater capacity of the battery is, and can be used for a longer time.

Q2: What types does laptop battery have?

A: There are nickel-chromium batteries, nickel-metal hydride batteries, lithium batteries, they are generally expressed as: Ni-Cd, Ni-MH, Li. In recent years, there appears a fuel cell in the laptop field. Today’s laptops generally use lithium batteries, but a few models still use the elimination nickel-metal hydride batteries, consumers can identify from the battery tag.

Q3: Why does the manufacturer only for one-year battery’s warranty?

A: For the short life of lithium ion. The chargeable number of ordinary lithium is only 400-600 times, specially modified products for 800 times, scrapped after using for two years.

Q4: Why battery using time is less than the manufacturers’ nominal time?

A: The test conditions are not the same. Some manufacturers use 8-cell battery for testing, but to the user is 6-cell battery; some manufacturers turn off all the procedures, lowering the LCD screen brightness, disable the interface by means of power to detect the use of time, which in everyday applications simply can not be achieved; some vendors only use software testing, software may lead to errors.

Q5: what should pay attention to about battery use and preservation?

Answer: Pay attention to these issues: the beginning of several charge must be filled with more than eight hours to fully activate the lithium battery; be careful not to over-discharge; best not to use the power adapter and battery at the same time.

Save attention: You’d better take out the battery each month to charge; Do not charge full when save the battery, charge to 40% ~ 50% of the electricity is suitable; stored in a dry cool place.

UL released standard study outline for electric vehicle batteries

October 26, 2009 8:57 pm

Underwriters Laboratories (UL) recently released its latest study outline about large-scale batteries for electric vehicles – UL Subject 2580. Prior to the official as a standard, this outline will accept a global standard technical committee (STP) for a comprehensive review. As traditional energy prices rising and more concerns on environmental issues, the use of electric vehicles in the coming years will be substantial growth, it is expected in the next decade, the annual hybrid electric vehicles and battery-powered electric vehicles for use will achieve 1000000-5000000.

Power Battery is the key to the development of new energy vehicles, it need to achieve fast charging, security and other high-performance, is the highest part of the technical threshold. UL electric car research framework introduced, will be able to help the growing number of electric vehicle manufacturers to improve the safety standards of their products, in this sunrise industry won the competition in head start.

How to distinguish the lithium battery is fake or genuine

October 25, 2009 8:53 pm

The price of fake lithium batteries generally much cheaper than the genuine, genuine and fake products in general can be seen from the price. However, because of counterfeit lithium batteries price on the market at times even exactly the same as genuine, so that consumers spend money bought a fake and shoddy products, the best way is to purchase in the regular shopping malls and brand stores, in the electronic digital market is easy to encounter counterfeit lithium-ion batteries. If you can see through the fake batteries certainly before buying would be a good thing, but if you’re not quite so deep “skill”, then we recommend that if you have questions to buy the lithium batteries, you can call the company’s consulting telephone for consultation. Now many large companies have established such a service telephone.

If you have already bought a piece of lithium battery but doubts about its authenticity, then the field test the using time is one of the most direct way.

1. When the first charge, we can look at the machine shows battery life time is whether close to the instructions marked time, the show time after full charge later should be close to the first time, if the time was too shorter than the standard time, that’s a fake battery.

2. If you find that the machine indicates that the battery can use for some time, but the machine automatically shut down due to lack of electricity, and this phenomenon has always existed, then this lithium battery is mostly counterfeit.

3. Fake battery using time is lower than the normal use of real battery time, for the first time may be more or less, but with the extension of the using time, fake battery performance will be getting worse and worse, and the using time will be shorter and shorter.

4. Fake battery will sometimes show the battery has been used up, but you can still use a longer-term, while the real battery shows that the battery power is quickly exhausted and the machine will automatic shutdown soon.
