Electric vehicles because of its advantages of light pollution which are favored by many consumers. Consumers buy electric car, the general length of the mileage as one of the main criteria to measure the quality of electric cars good or bad. It is worth mentioning that the quality complaints in a large number of electric vehicles, battery problems accounted for more than 95%, because the battery is to determine the electric vehicle for exercise which was play an important factor in mileage length. Maintenance of electric vehicle batteries,what issues should we pay attention to in the spring and summer ? the following are some good suggestions of Aucma electric cars of Xiao bian.
Step 1: Do not store your battery in a long time after you used it
The state of the loss of electricity means no timely charge the battery after use. Electric vehicle batteries in the storage is prohibited in the state of the loss of electricity, it is easy to sulfate, lead sulfate crystals attached to the pole plate, plug the electric ion channels, resulting in insufficient charging, vgp-bps9 battery capacity decline. Loss of electricity the state the longer the idle time, the heavier the battery is damaged. Therefore, Aucma electric cars Xiaobian recommended that your battery is left unused, a monthly supplement to power once, so better to keep the battery healthy state.
Step 2 : regular inspection
Electric vehicles in the course of continued mileage in a short time a sudden drop in more than ten kilometers, most likely at least one battery in the battery pack off grid plate softening, the electrode active material shedding short-circuit phenomenon. Then check the store should be approaching electric car, repair, or with a group. This relatively prolonged the life of the battery pack to maximize savings.
Step 3 : avoid the instantaneous discharge
Electric cars at the start, manned, uphill, with pedal power to avoid the momentary high-current discharge. The large current discharge easily lead to produce lead sulfate crystals, to the detriment of the physical properties of the battery plates.
Step 4: strict control of the charging time
Accurately grasp the charging time should be based on the actual situation, the reference to usual frequency of use and mileage situation, but also pay attention to the size of the battery manufacturers to provide instructions, and supporting the performance of the charger, the charging current size and other parameters to grasp the charging frequency. General Casio NP-20 battery charging at night, the average charging time in about eight hours. If the shallow discharge, electric vehicle batteries will soon be full, continue charging will overcharge phenomenon, leading to cell dehydration, fever, lower battery life. Therefore, the battery depth of discharge for one charge 60% -70% of the best riding mileage can be converted into actual use, charging based on actual conditions necessary to avoid harmful charge.
Step 5: don’t put the battery under the sun
Electric vehicles is prohibited in the sunlight. Temperature environment causes the battery internal pressure increases the pressure limiting valve is forced to open automatically make electric car batteries, a direct consequence of increased loss of water of the battery, the Inspiron 1545 battery battery excessive water loss will inevitably lead to the battery activity accelerated plate soften, charging fever, when the shell casing from the drum, deformation fatal injury.
Step 6: pay attention to the heat of your charging plug
The charger output plug loose contact with the surface oxidation phenomena will lead to electric car charging plug fever heat for too long which will lead to short-circuit of the charging plug, direct damage to the charger, and lead to unnecessary losses. Found out that the situation should be promptly removed the oxide or replace the connector.we hope that these suggestions could give you a help.

Physicist organizational network recently reported that U.S. scientists developed the household washing machine-sized combo of new equipment, not only the microbial purification of sewage, but also to produce electricity. The study report was submitted in the 243 session of the American Chemical Society National Conference and Expo on March 29.
Dr. Craig Venter Institute Orianna said: “Our initial prototype of the integration of innovative technology improved, so that it more effectively than ever before sewage treatment, while the costs fall by half; and its energy recycling capabilities from 2% to about 13% if the technology can be commercialized, can produce more electricity and more Canon nb-5l battery .it can eventually be free of sewage treatment, which means that in developing countries or the United States Southern California and other dryland This cycle technology so that more waste water become clear.
The new device uses a microbial fuel cell can use hydrogen and oxygen to produce electricity and drinking water. Micro-organisms naturally present in the sewage through metabolism, digestion of organic matter in the decomposition of sludge. Dr. Orianna new microbial fuel cell obtained from conventional sewage treatment plants, Casio NP-20 battery sewage plants, and even has the potential to break down harmful pollutants such as benzene and toluene in the sludge.
The experiments carried out in San Diego near the sewage treatment plant, the device can handle weekly amount of 20 gallons to 100 gallons of waste. The researchers used a graphite electrode and PVC frame to replace titanium parts. For this reason, a new microbial fuel cell waste disposal costs of about a gallon $ 150, only half of the previous prototype. The team hopes to eventually be able to achieve a more competitive cost than the existing water treatment technology, a gallon will be less than $ 20 or less.
The same time, the efficiency of the new equipment is six times the previous prototype, the sludge into electrical energy efficiency of 13%. The researchers explained that once the device is to expand the scale, the run up to 20-25% efficiency, can generate enough electricity to run the sewage treatment plant. It is estimated that a typical sewage treatment plant may consume a power of 10 000 or more families. The future, microbial fuel Fujifilm np-150 battery may replace some of the existing city sewage treatment system.

Myths Rechargeable Batteries For Laptop And Mobile
It is often said that the first time we use a device equipped with a lithium battery (as I say, they are often called Li-ion) should be allowed to charge for eight or ten hours, but two or three hours (typical load one of these batteries) this device tell us that the battery is fully charged. This really was recommended when using Ni-MH batteries, but with the Li-ion is not absolutely necessary: a lithium battery always carries an overload protection circuit which is responsible for turning off the power once detects that the cells that make the battery has reached its standard level (usually from 4.2 volts).
Therefore, once the device says “full charge” does not enter more current to the battery and has no effect whatsoever on the leave her more time with the charger connected. Also they say that should do complete cycles of loading and unloading to avoid the “memory effect”, that Ni-MH batteries was that if we put in charge a completely discharged was not missed part of the capacity of the battery from overcharging some of its cells.
In Li-ion batteries this is not necessary, and even more frequently as recommended and load cells are less time with current flowing through them. Li-ion batteries have no memory effect either and therefore we can load them better we come without having to wait until they are completely sold out as it did with the old batteries.
There are a number of things that are the worst thing that can make a lithium battery:
· The Heat: Li-ion battery loses capacity if stored in hot areas. Best suits them cold, but with keeping them below 25 degrees Celsius is more than acceptable. This is why batteries degrade some laptops very quickly if the design has not been taken into account that the area of the battery should be cold, ie, away from the hard drive and microprocessor.
· Store fully charged for a long time: it is best to keep a battery at half load, if we do so with the battery fully charged your battery cells suffer and will deteriorate over time. It should be stored fully discharged for a long time what we will see in the next point.
· Leave the battery to discharge completely, if a Li-ion battery becomes completely lost its charge will not load. This point is reached when the device is off because the battery has a very low level of energy, since that is responsible for the above-mentioned circuit protection. Over time the battery is losing charge itself (self-discharge rate) and if we can load many months to lower the minimum threshold needed to start charging and the battery unusable.
To extend the battery life:
* Reduce heat: The Li-Ion are highly susceptible to high temperatures, so use your devices in a cool environment will extend its functionality.
* Turn off wireless transmissions: Infrared (IrDA), Bluetooth and Wi-Fi are real vampires electricity, being equivalent to maintaining a cell at any given time. Turn off these features when necessary.
* Avoid using your CD or DVD: The spending not only borne by the laser, but also the motor that spins the disc. Better not to mention the writers?
* Reduce the brightness of the screen: Some teams do it automatically, generate less light, less energy demand.
* Remove memory cards or USB keys: Do not let its small size fool you, energize it requires an additional flow of electricity. This is especially true for small devices such as phones or PDAs.
* Avoid using audio applications: Even with headphones, the sound generation requires a constant expenditure of energy. Worse still if they feed external speakers.

Energy saving of your laptop
For longer be able to use your laptop without a power outlet nearby, you can use power management (power management) work.You can change the BIOS settings thereof. For example you can slow down your CPU to work (economically) if you do not taxed. Whether your hard drive if you disable Dell xps m1710 battery for X number of minutes have not used.Usually there are already pre-configured settings such as (Maximum safe, maximum performance, etc. ..)
Do not start randomly changing settings, but think first moment about the possible consequences.The most energy at a laptop screen, CPU, CD-ROM drive and hard drive. (Usually in that order.)Working to increase the HP pavilion dv5000 battery can be one or more of the following things:
* Adjust the brightness of the screen as low as possible. You just save not only energy, but the life of the “lamp” will extend.
* Turn off your screen when you’re away. Or get a short delay the screen saver. (Use a “useful” screen. Flying Windows logo are not useful: You save nothing, instead you consume extra processing power.)
* Lower the volume or use headphones.
* Make sure the air vents (in and out) is not anything to be blocked, so that the processor is kept cool. Heavy processors and memory have their contribution to the heat, so the less things you do together, the less heat, less cooling required, and the longer your HP pavilion dv5 battery lasts.
* Remove CDs from the CD-ROM drive if you are not using. Some laptops have the CD constantly spinning and a lot of energy.
* Remove PC cards (PCMCIA, Cardbus) if you are not using them. Make sure to buy these cards if they are in an energy saving mode can be put.
* Use the sleep mode or hibernation (Suspend To Disk) mode, or turn off the computer when you’re just not used.
Turn on the external connectors (serial, parallel, infrared, USB, …) in the BIOS if you are not using them.Never work without batterySome clever people who read all this and to protect their HP pavilion dv4 battery will perhaps be inclined to their laptop without the battery (but with power) to work. This also is not recommended.The tension on the wall is full of peaks and valleys. These “wrinkles” are effectively eliminated from the battery, which actually serves as a capacitor.
Without battery, these lines passed to the laptop-electronics that can usually not take place and sooner or later gives up the ghost. (And a battery is still cheaper than a new laptop …)Old batteries are defective liver is best reflected in the manufacturer. These can then be recycled. (And sometimes you get discount when buying a new battery.) If you manufacturer the HP pavilion dv7 battery still will not take, write a letter of complaint and deposit it in small or hazardous waste at a battery collection point nearby.

When Sony introduced the first lithium-ion battery in 1991, knew the potential risks to safety. A memory of rechargeable lithium metal was previously issued a stern warning of discipline must be careful in dealing with the system of batteries with high energy density.
Pioneering work of the lithium battery began in 1912 by GN Lewis. It was not until 1970, when the first rechargeable lithium batteries became commercially available. Attempts to develop rechargeable lithium in the eighties. These early models were based on lithium metal and offers a very high energy density. However, the inherent instability of lithium metal, especially during charging, put a brake on development. The cell had the potential for heat dissipation. The temperature would rise rapidly to the melting point of lithium metal and cause a reaction. A large quantity of rechargeable lenovo t400 battery sent to Japan had to remember, in 1991 after the package on a phone released hot gases and inflicted burns to the face of a man.
Due to the inherent instability of lithium metal, research shifted to a non-metal lithium-ion battery. Although slightly lower than the energy density, the lithium-ion system is safe, provided that certain precautions are met when charging and discharging. Today, lithium-ion battery chemistries be more effective and safe. Two billion cells are produced each year.
Lithium ion is twice the dell latitude d630 battery of a nickel and four times that of lead-acid. Lithium ion is a low maintenance, an advantage that most other chemistries can not claim. There is no battery memory and requires no programming to extend their life cycle. Nor is the lithium-ion batteries have the problem of lead-acid sulfation occurs when the battery is stored without periodic charging finish. Lithium ion has a low self-discharge and the environment. The removal of the causes minimal damage.
With the widespread use of lithium ion batteries in cell phones, digital cameras and macbook pro battery, as is inevitable question. One in all, 200 000 failure rate has led to the withdrawal of nearly six million lithium batteries used in laptops packages produced by Dell and Apple. Battery heat-related chess is taken very seriously and producers have chosen a conservative approach. The decision to replace the batteries puts consumers at ease and the lawyers at bay. Let’s look at what’s behind the withdrawal.
Sony Energy Devices (Sony), the manufacturer of lithium ion cells in question, said that on rare occasions, microscopic metal particles in contact with other parts of the dell latitude d830 battery, causing a short circuit in the cell. Although battery manufacturers strive to minimize the presence of metal particles, complex assembly techniques that the removal of all metal powders almost impossible. High energy density of the cells with ultra-thin separators are more sensitive to impurities than the older models with low grades Ah.
A sweet short only cause an increase in self-defense. Little heat is generated due to the discharge of energy is very low. However, if a sufficient number of microscopic metal particles converge at one point, a short circuit can develop serious and significant current flows between the positive and negative plates. This causes an increase in temperature, leading to thermal runaway, also known as ventilation with a flame.
Lithium-ion cobalt cathode (as recalled dell inspiron 1545 battery) should not exceed 130 ° C (265 ° F). At 150 ° C (302 ° F), the cell becomes thermally unstable, a condition that can lead to thermal runaway in which the gases are vented fire.During a thermal runaway, the heat of the defective cell may extend into the next cell, making it unstable and thermally. In some cases, there is a chain reaction in which each cell disintegrates in your calendar. A package can be destroyed in seconds in the short to dwell on a number of hours that each cell is consumed one by one. To increase security, the packages are equipped with dividers to protect the cell does not spread to neighboring cells.

Introduction To New Nokia 100 and 101
The Finnish company no doubt a few years ago was the undisputed leader in the mobile phone segment in all different ranges, so we had an insurmountable Nokia N95 and simpler models among these simpler models had the legendary Nokia 1100. This model is perhaps the simplest mobile phone in the history of Sony vgp-bps9 s but in turn the model that has achieved sales amount and in turn has several interesting figures such as the mobile phone.
It has lasted throughout the time and more people have used throughout his life. According to the Finnish manufacturer Nokia 1100 is the most mobile phone text messages sent throughout history and is also the mobile phone that many people used as a secondary phone. Now the company is seeking to achieve the same but with a Sony vgp-bps9 adapted to 2011. This similarity and starts from its name and the company launched the Nokia 100 and Nokia 101.
In the first quarter Nokia realized that there is a large public purchasing dual SIM devices and because it launched its two newest models, the X1-01 and C6-00. The mobile phone manufacturers ‘real’ recently that there previously had to fall into the Chinese replicas to have this feature. So thanks to the great success of the latter Toshiba pa3534u 1brs battery the company decided to launch two new models with this feature and it also achieve very similar to the one Nokia 1100.
Both phones are targeted for emerging markets, both have the same design, same 1.8-inch TFT, torch, pre-loaded games and FM radio. But in the case of the Nokia 101 this is the only one of two dual SIM and have a little more sophisticated, including for example a more powerful pair of speakers, mp3 player attached and support for Lenovo 40y6797 up to 16 GB. According to its directors in emerging markets such as 85% of the population have mobile phones instead of smartphones simple.
Everything reminds us of the Nokia 1100 from its small screen, even in this case is to color, games and also had that model and turn the flashlight that these models were typical at that time. The devices also will be released this semester in Europe and the MSRP will be no more than twenty dollars for the Nokia 100 and 25 euros for the Fujitsu fpcbp64. Although Nokia has always wanted to have other models focus on “strong” or workgroup and the company knows that the mobile phones of this type are very important.
Nokia wants to again be the leader in this segment and surely these two teams is going to achieve and by the company say their phones have an advantage over their competitors and have a colorful screen, rugged construction and a battery life. The Fujitsu fpcbp155 is sold in the colors Black and Coral Red Phantom turn the Nokia 100 offers five colors, we have the Red Coral, Legion Blue, Pink Festival, Ocean Blue and Phantom Black.

Fujitsu Lifebook T900 Review
The laptop is not cheap, besides, is aimed at business users, so the quality of materials and assembly imposed very strict requirements. There are three types of plastic – black, covered with matt black paint, which are made of panels and lid panels around the matrix, white, painted in a light silver color with a smooth but not glossy, and slightly rough black unpainted plastic made pan and cover compartments on the bottom.To freshen up a little design on the lid of the Dell Inspiron 1520 battery laptop has been added to the narrow bar of black glossy plastic, which, of course, quickly collects fingerprints.
In assessing the quality of assembly could not find a single joint or irregular large gap. All the parts fit very well, and find fault with almost no sense. When trying to twist and compression does not creak, the hinge connecting the base and the display is reliable and sturdy, and denied even the hint of a backlash.Complaints may result unless the main battery mount two ordinary snaps, which, unlike traditional locks can unexpectedly break. Although it is worth noting that the backlash mounting the Dell Inspiron 1545 battery is not at all.
The back side of the case is extremely loaded, here are the hole install a security lock, a pair of USB-ports, LAN port, RJ-45, a pair of small air vents, and rubber plugs are hidden by individual port D-Sub (VGA) connector and SIM-card. Usually when you install the SIM-card has to pull out the Inspiron 1720 battery, which is not specifically promotes ease of use, but if test “tablets” installation or replacement of the SIM-card is just a few seconds.
On the left side of the empty space is not at all. There is a jack to connect an external power supply, ventilation grille with large cells, a pair of standard audio, USB and IEEE1394, slot cards installed ExpressCard , memory cards and smart cards, as well as installing nest pen.Compared with the other side faces the right-hand side is almost empty there is only the second connector fit a lock and cover the optical drive tray. By the way, the drive is easily removed with a single motion, and in its place you can install a second Dell Inspiron 6000 battery with 41 Wh, which together with the main tank provides 104 Wh!
Flat bottom of the laptop, but the vents there is little that is a bit confusing in light of the fact that the 13-inch baby has a powerful quad-core Intel Core i7 620M, which is not good cooling hurt. The user then is available only to the Dell Inspiron 640M battery module compartment. Both slots are occupied, but can be replaced full-time modules of 2 GB to 4GB. There is also a connector to connect the port replicator, which, among other things, adds HDMI-port and a socket connection to the telephone network RJ-11.
Rotate the lid has a limited move to 180 degrees in each direction, which is sufficient for the translation of “pills” from the normal mode to Latitude D810 battery tablet. In tablet mode on the edge of the display are four hot keys to scroll sensor, a pair of microphones, the window is a web-camera, three indicators Lock-keys, power key and the sensor reading fingerprints, that business model is very important and necessary bonus.

Bento: Notebook, Tablet And Smartphone
An interesting concept but a little farther from reality is called Bento, this is a concept that integrates a computer notebook, tablet and smartphone.
With the arrival of the new tablet market, which was inaugurated with the launch of the first of the iPhone this created a niche of sales between the space between the notebook and smartphones. The designer responsible for the project is called Bento Rene Lee and I think this concept in red uses each of the different forms of a Dell inspiron 1564 battery to increase the connectivity of all devices and also the lifetime of the devices.
This project was a competition created by the Fujitsu company, called A Life With Future Computing, is present a dock that includes a monitor 15 inch OLED display, integrated with a rectangular 11-inch tablet that serves as an extension of the monitor or keyboard and turn a smartphone with 4 inch size on your Dell inspiron 1570 battery at once which can be a “touchpad”. In terms of design is undoubtedly attractive for its small thickness and very light weight.
In addition to this we have a lithium battery that is recharged with solar power and hard disk type 1 TB SSD, these two components are removable. The idea no doubt is great when we think we can have a Dell inspiron 1764 battery working together, because not only have everything in one place but all three screens can work together to perform functions that require more than one.
As we see from the pictures could have such a score on the monitor, the piano keyboard on the tablet and a sound controller on the smartphone. By this all men divide their processor and RAM. Being a concept really is a bit hard to believe that soon we will see this Dell xps m1530 battery, but we lose nothing to dream and thanks to its design and its high functionality would be a bestseller.
Not only does your screen flexible solid or small notebook, the designer also remove the trackpad device to save space. But to have these functions, the creator inserted a notebook mouse in the notebook, just enough to push a button so that it arises from within the Dell vostro 1500 battery. Feno in turn is half the size of such a MacBook Air, but in turn has the same screen size of a MacBook Pro 17-inch all thanks to its flexible OLED display.
In addition to this keyboard which has a great similarity with the Apple hardware keyboards was also reduced, so that people rest their hands on a flat surface such as Van Hoof said, providing that the user can more simply typing in their Dell vostro 1400 battery. Feno is another very interesting concept and perhaps a little closer to reality than the previous one, this is a foldable notebook designed by designer Niels Van Hoof, by having a flexible screen size is more compact, easier to carry.

Nikon Coolpix S4000
Camera with touch screen is often associated with high cost, because, basically, it’s high-end of first-tier manufacturers. But in the Nikon, apparently decided to break that stereotype, by launching the camera Coolpix S4000, retail value of an average of $ 180, which, in principle, even lower-middle price range. However, the presence of the touch screen does not entail the appearance and all other functions inherent in older models. S4000 camera is fairly simple, configuration and additional functionality a bit, while the Nikon en-el5 camera is not even an optical stabilizer.
Camera Series S (Style) usually come in several color options. Coolpix S4000 is available in black, silver, purple, green, blue, orange and red colors in general – for every taste. Testing was provided by the Nikon en-el7 camera in black. The dark chamber often suffer from prints, but in the case of the S4000 is no such problem – metal body with a rough surface is covered with dull paint, so the fingerprint is almost invisible.
Quality paint is high, so the Nikon en-el8 is difficult to scratch, let alone transportation without a shroud or a specialized bag to her and not scary. To build quality no complaints. Housing, though subtle, but very hard, so when trying to twist it could not bend one iota, even more effort in addition, with the camera did not utter a sound. Camera fairly easy, so not really interfere in the breast pocket of a light shirt.
In front are the lens, built-in microphone hole, the window flashes and the LED lights AF, which also serves as an indicator of sleep timer shutter release. Behind almost all the space has a large touch screen, which is located to the right of the flash-ready indicator, a key mode selection button and go to playback mode. At the top are the power button and shutter release, the latter surrounded by a Nikon en-el9.
Bottom compartment are inserted the battery and memory card, a plastic tripod socket, opening the system dynamics, as well as the universal connector micro-USB-cable.The left side surface is empty, and the right is a massive metal eyelet lace fastening. In a small Nikon en-el14 mounted large display with 3-inch. As already mentioned, the display is not simple, and touch. Of course, from the inexpensive cameras can not expect any trendy “chips” like multitouch technology – management is quite simple, any frills interface does not shine. But now is not about that.
Horizontal viewing angles are rather large test chamber, and the vertical ones too small, so, for example, when looking at the display bottom when shooting up arms outstretched, it practically can not see anything. With flowers and lining the Nikon d60 battery is slightly cooler than the pictures when viewed on a PC. The display brightness is sufficient for operation in all conditions, even when direct sunlight is still readable, though a bit blind.

ASUS ROG G74 Review
The G74 follows the design of the G73 , inpired they say in a Stealth bomber and F-117 Nighthawk ASUS Design low lines , the special department to design the most exclusive models of the Taiwanese company. Reference to F-117 mainly because of the ergonomic five-degree angle of the Acer BTP-58A1 battery and the complete redesign of the ventilation system and heat dissipation that eliminates the back flow which decreases heat the temperature reached by the team and their level of emitted noise.
For the G74, ASUS is committed to screen 17.3-inch, LED backlit, Full HD resolution 1,920 x 1,080 pixels and Color-Shine technology included in the G73. The most noticeable change in front of it is the incorporation of a special version of the G74 (SX-3DE) with 3D display of 120 Hz and a kit of NVIDIA 3D Vision. ASUS modernizes and its line of Apple A1079 battery notebooks offering powerful three-dimensional vision as we recently saw in the Qosmio X770 Toshiba model similar in size and focus.
The ASUS G74 is more powerful than the model Toshiba in the amount of RAM and storage capacity. Includes quad-core microprocessor Sandy Bridge Intel Turbo Boost technology and Hyper-Threading and dedicated physical button for Macbook Pro battery. The inclusion of Blu-ray optical drive as standard and a powerful dedicated graphics NVIDIA GTX 560M with 3 GB ensures maximum performance in entertainment and gaming performance.
Also carefully audio section of the G74 supports EAX Advanced HD 5.0 technology and EAX TruStudio THX subwoofer and built. The connectivity is complete with Ethernet LAN, Wi-Fi,Compaq Presario CQ50 battery and Bluetooth, with HDMI and USB 3.0 ports plus a 2-megapixel webcam.
Although the section of autonomy is not his strong point includes a 8-cell Inspiron 1545 battery and 5,200 mAh . Aimed to replace desktop machines in paragraph also emphasizes portability with a weight of over four kilograms. With Windows 7 pre-installed ASUS G74 will be available next week at least in America. As the Qosmio X770 is not cheap but offers a spectacular design and high performance for multimedia entertainment and games.
