Car Battery Ni-MH battery will gradually erode the market into the mainstream
Dec. 31 news, new energy vehicles to become the development direction of the global auto industry has no doubt,laptop battery from the more mature technology of hybrid vehicles to the latest trend of the pure electric vehicles, to fuel cell vehicles, battery technology has undoubtedly become the constraints of new energy vehicles the main factors.

Zhang Shulin, pure electric vehicles and fuel cell vehicles the lowest energy consumption and emissions, should be the future direction of the primary election, relating to lithium and nickel-metal hydride battery is the future technical direction. China Ni-MH battery has reached 140 million watt-hours of production capacity, is expected to reach 3.6 billion by 2010, while the lithium battery there are 900 million watt-hours of production capacity, to reach 40 billion by 2010, when these batteries can meet the 15 million electric vehicle needs. The current cost has dropped to 3 yuan per watt.
As for plug-in electric cars and hybrid vehicles in use, lithium nickel-metal hydride batteries are more than prospects. Fuji economic analysts believe that the mainstream nickel metal hydride batteries will continue into 2011, but after 2011, canon NB-1L battery Li-ion battery will gradually erode the market share of nickel-metal hydride batteries, the agency estimated 2009 vehicle with a nickel-metal hydride rechargeable battery in the world size of the market than the previous year by 23.7% to 92 billion yen, but the 2015 car with a Ni-MH rechargeable battery market will fall to 55 billion yen.
Now, more and more car manufacturers to choose lithium batteries as the battery power of new energy vehicles, such as Ford, Chrysler, Toyota, Mitsubishi, Nissan, Hyundai and so on. The domestic auto maker BYD, Geely, Chery, Lifan, ZTE and other car firms also have their own hybrid and pure electric vehicle powered by lithium batteries.
With the traditional chemical power (such as lead-acid, nickel cadmium, etc.), compared with a pollution-free nickel-hydrogen batteries, high specific energy, high power, fast charge and discharge, resistance to abuse and so many excellent features, has wide application and market prospects.
Beijing Nonferrous Metal Research Institute has in the “July”, “August”, “Ninth Five-Year Plan” assume “863″ high-tech projects and related nickel-hydrogen SONY NP-55 Battery SONY NP-FM70 Battery battery research of key materials, and in 1993, the first time in 1996 to complete development of open-rich liquid-type nickel-hydrogen batteries, and successfully run the electric tricycle and electric vehicles. Period, has established three million cylindrical sealed nickel-metal hydride batteries and nickel-metal hydride battery production line with the relevant key materials such as hydrogen storage alloys, nickel hydroxide, nickel foam production line.
Your new laptop battery comes in a discharged condition and must be charged before use (refer to your computer manual for charging instructions). Upon initial use (or after a prolonged storage period) the Dell Vostro 3300 battery may require two to three charge/discharge cycles before achieving maximum capacity

When charging battery for the first time, your computer may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Just remove the battery from the computer and repeat the charging procedure.
It is important to condition (fully discharge and then fully charge) laptop battery every two to three weeks. Failure to do so may significantly shorten the battery’s life (this does not apply to Li-ion batteries, which do not require conditioning). To discharge, simply run your device under the battery’s power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in your user’s manual.
If laptop battery will not be in use for a month or longer, it is recommended that it should be removed from the device and stored in a cool, dry, clean place.
It is normal for laptop battery to become warm during charging and discharging.
A charged Dell Studio 1749 battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period.
