Lead-acid battery after 100 years of development and improvement has become widely used in the world of a chemical power, with good reversibility, voltage characteristics of a smooth, long life, wide range of applications, raw materials rich (and renewable) and Low cost and so on. Standard Lead Acid Battery Mainly used in transportation, communications, electricity, railways, mines, ports, defense, computer, scientific research and other areas of national economy, social production and business activities and human life indispensable products.
The automobile industry is the pillar industry of the country as the key development. With the rapid development of the automobile industry, the amount of lead-acid batteries is increasing rapidly, accounting for about 80% of the total lead-acid battery consumption. By the year of 2010, 7.5 million, the social security will reach 60 million, China's car demand will be second only to the United States, Standard Lead Acid Battery Japan ranked third in the world, if the start of the use of sealed lead-acid battery development success, will be a considerable market, Automotive electrical system voltage from 12V open to 24V or 36V, will lead to lead-acid battery to bring new opportunities, no matter what kind of voltage, must be divided into two parts, one of which is for large discharge electricity load service, For use in engine starting, the traditional liquid-rich lead-acid battery can meet this requirement, Standard Lead Acid Battery the other part is used for low-rate deep cycle use, VRLA battery is best suited for this purpose.
China's motorcycle production is the first time in 1993, China's motorcycle market is still in demand for the first time, electric motorcycle is a large latent market, this area for the lead-acid battery opened up New huge market. The current use of the motorcycle industry is still the main open battery, Standard Lead Acid Battery but sealed battery to replace the battery is an inevitable trend, the current motorcycle ownership of only 10 to 11 / thousand people, while the international level of 20 / thousand people, Far worse, so the motorcycle production will grow steadily.
The communications industry is the main user of lead-acid batteries, especially VRLA batteries account for two-thirds of the total market demand. Medium and small sealed batteries in the main application areas of post and telecommunications systems for users access network and communications network. User access network is the Ministry of Information Industry "15" during the development of an important direction, from 2000 onwards, the development of this area showing a strong momentum, especially in Beijing, Shanghai, Guangdong, Jiangsu and other economically developed areas and large , In the city, have dropped into this advanced communication network, with the information economy continues to develop, this area has great market potential.
Lead-acid batteries, we are in daily life, work are often used, but do not know everyone on the "lead-acid battery capacity recovery device" whether to know? This article collected a number of information, I hope this article readers can have a greater reference value.
Lead-acid batteries used for a long time, not in time to charge or in the discharge state for a long time without shelving, the plate will produce a lot of lead sulfate grain, this phenomenon is called sulfation (referred to as vulcanization). When the micropores on the lead plate are blocked by lead sulfate crystals, the effective area of the lead plate in the chemical reaction is reduced, Standard Lead Acid Battery the battery capacity is reduced and the load capacity is reduced.
When the lead sulfate lead between the lead hole between the lead so that most of the lead can not participate in the charge chemical reaction, with the conventional charging method can not make the battery to restore capacity, the battery is scrapped. 80% of the lead-acid batteries are eventually scrapped by severe vulcanization.
At present, there are two ways to restore capacity of old lead-acid batteries:
1, the battery repeated several times the charge / discharge cycle;
2, with a larger pulse current to charge the battery
But these two methods have little effect.
The circuit uses a new technology to restore the capacity of lead-acid batteries. It charges the battery with a brief and powerful pulse current and discharges the battery during intermittent charging. This is the most effective way to eliminate the harmful sulphate deposits on the plate and to restore the capacity of the battery. The circuit is unique in that the energy required for the charge pulse is taken from the battery itself rather than the external power source. The battery is powered by the circuit for most of the time in a discharge state, which is actually an integral part of the entire discharge process. Standard Lead Acid Battery Only in the battery remaining capacity is very small, only in the battery and the recovery of the connection side in parallel.
