1, automobile, motorcycle starting batteries
1.1 Automotive Industry
The automotive industry as a focus on the development of the country's pillar industries, with the rapid development of automobile industry, the amount of lead-acid batteries are also rapidly increasing, the entire lead-acid batteries account for about 80% of the amount of the 2010 car production will go to 750 10,000, will reach the community to maintain the volume of 60 million, China's demand for motor vehicles after the United States, Japan ranked first in the world 3, if the start-up with the successful development of sealed lead-acid battery, it will be a very big market, for motor vehicles electrical system voltage from 12V to 24V or open 36V, lead-acid batteries will bring new opportunities, no matter what voltage, the power must be divided into two parts, one of which is for the large current discharge load services, such as on engine start-up, the traditional lead-acid battery-rich liquid can be suitable for such a request, the other is a low magnification for deep cycle use, valve-regulated lead-acid batteries-presario v5000 battery, compaq presario v4000 battery most suited to this purpose.
1.2 Motorcycle Industry
China is the world's motorcycle production and sales of the first big country, China's motorcycle production in 1993 for the first time in Japan, the Chinese motorcycle market is still in peak demand, the electric motorcycle is a large potential market for lead-acid batteries in the field to open up a new huge market. Motorcycle industry is currently opening the battery is still used, but the sealed battery has been replaced by opening the battery is an inevitable trend of motorcycle ownership in China is only 10 ~ 11 / people, while the international standard for the 20 / thousands of people, very different, so motorcycle production will grow steadily.
2, communication with lead-acid batteries
China's postal and telecommunications industry is currently in a high-speed development period, the average annual growth of more than 20% of the scale of investment in fixed assets has been 7 years more than 100 billion yuan. Not long ago, in fact, according to an authoritative source of statistics on domestic phone subscribers has reached a maximum of 460 million, including fixed-line telephone and mobile phone users, about half are over the "goal of 15" figures, are expected in the next 20 years, China will be the world the largest telecommunications market.
Communications industry is the major user of lead-acid batteries, especially VRLAB currently accounts for two-thirds of the total market demand. Small and medium-sized sealed battery system in the post and telecommunications applications for the user access network and communication network professionals. Users to access network is the Ministry of Information Industry, "15" during one of the major directions of development, beginning in 2000, the development of this area showing a strong momentum, especially in Beijing, Shanghai, Guangdong, Jiangsu and other economically developed areas and large, medium-sized cities, one after another into the advanced communications network, with the continuous development of the information economy, a huge potential market in this area.
3, the power to use lead-acid batteries
The power industry focus on the development of our country's basic industries, from 1998 to 2002 the annual average installed capacity in more than 20 million kW, over the years, as a result of urban and rural power grid construction and transformation of inadequate investment, which lags behind the power grid construction, limiting the city and rural electricity demand and consumption. To increase the electricity restructuring, and investment funds to adjust the power to speed up the urban and rural power grid construction and transformation of the pace. From 1998 to 2000, the country's power companies to invest 380 billion yuan for the urban and rural power grids, the focus will be building a power shift from the power grid construction. From 2000 to 2005 a year for the western and eastern power grids in urban and rural areas supporting the follow-up project will reach 80 billion yuan investment.
4, Railway diesel locomotive and electric locomotive used lead-acid batteries
In recent years, China's infrastructure, increasing investment, the railway infrastructure construction is one of the key points. "15" during the national railway system in the total investment will reach 360 billion yuan, the battery in great demand, the end of 2002, the number of diesel has more than 12,000, up to 4600 Electric Locomotive.
5, UPS batteries (small and medium-density)
UPS uninterruptible power supply system that is mainly related to computers and supporting the use of precision instruments, the core of their batteries. In recent years, with the computer in the country's domestic popularity, UPS market has been driven up accordingly, UPS rapid development in the Chinese market.

6.1 Electric Vehicles
With China's economic development, increase the volume of fuel in vehicle ownership, vehicle exhaust emissions of urban air pollution has become one of the major sources for environmental protection as the Chinese government will implement the strategy of sustainable development an important aspect of the country in 1996 to start car the industrialization of major scientific and technological projects, including development of concept cars, electric cars key key components (batteries, battery management, etc.). As a power battery electric vehicles, many different types of research, there are lead-acid batteries, nickel cadmium batteries, nickel hydrogen batteries, sodium - nickel chloride batteries, lithium-ion batteries, fuel cells. According to the Chinese electric vehicle development plans, expectations will be buses, taxis, the use of electric vehicles as a priority, so the need to develop low-cost electric car batteries, in 1991 the country will be lead-acid batteries for electric vehicle research and development as a key project, the current The biggest problem with the existence of uniform consistency is poor battery.
6.2 electric bicycle battery
20th century since the 90's, with the rapid economic development, there is increasing emphasis on the quality of life. On the one hand, from the environmental point of view, on the other hand, has a lightweight from the start of private vehicles, resulting in a demand for electric bicycles. At present, the electric bicycle battery configuration is the most VRLA battery (referred to as small dense), which is in a sealed lead-acid batteries based on lead-acid batteries, after performance improvements, especially in the specific energy and cycle life a breakthrough, there are 108 domestic companies and the Institute of Electric Bicycle valve-regulated lead-acid batteries used for development, but so far are still in the high-speed than the energy is not high enough and deep enough and long cycle life of the shortcomings of , to a large extent the impact of the electric bicycle industry's rapid growth. Maintain the domestic bicycle 200 million of annual sales volume in 2500 ~ 30 million, the electric bike for the current annual sales of about 100,000, once the technology is mature, there will be an explosive growth in demand for at least a year reached 2,000,000, an average configuration 24V12Ah, the average life span of a year, then the battery in the amount of support is expected to reach 580,000 kwh, social retail volume of up to 2,880,000 kwh, valve-regulated lead-acid batteries from the current technology development situation , it was entirely possible to meet the needs of the product.
7, lead-acid batteries with new energy
The structure of energy in today's world is moving in the direction of the development of the green, green new energy such as wind energy, solar energy is being developed and utilized, and the electric power industry has become pavilion dv2000 battery, hp pavilion dv6000 battery, hp pavilion dv2500 battery an integral part of important.
