Battery free lead-acid battery battery usually means that it is a car battery in the battery case, belong to the secondary battery. It works: When an electrical charge to make use of external regeneration inside the active substance, the energy is stored as chemical energy 12v car battery, when you need to discharge again convert chemical energy into electrical energy output. We used lead-acid batteries can be divided into three categories, namely, ordinary batteries, dry charged batteries and maintenance-free batteries three. An ordinary battery: ordinary battery plates are made of lead and lead oxide electrolyte is an aqueous solution of sulfuric acid. Its main advantage is that the voltage stability, cheap; the disadvantage is the low specific energy (ie energy per kilogram of battery storage) life is short and routine maintenance frequently. 2, dry charged batteries: Its full name is dry charged lead-acid battery, its main feature is the negative plates have a higher storage ability, in a completely dry state, the resulting electricity can be saved in two years, the use of When, just add electrolyte, so after 20-30 minutes can be used. 3, maintenance-free batteries: Maintenance-free batteries due to their structural advantages, the consumption of electrolyte is very small, in the life of the basic need to add distilled water. It also has shock, high temperature, small size, low self-discharge characteristics. Normal battery life is generally twice. Maintenance-free batteries on the market, there are two: the first one at the time of purchase disposable after use, do not need to add electrolyte maintenance (adding replenisher); the other is the battery itself, the factory has been added to the electrolyte and sealed good The user simply can not add replenisher. 2 volt lead-acid battery, 4-volt, 6-volt, 8-volt, 12-volt, 24-volt series, capacity from 200 mA to 3000 when Ah. Lead-acid batteries are based on AGM (absorbent glass mat liquid) technology and calcium grid plate rechargeable battery, with excellent high-current discharge characteristics and long life. It does not require the use of added water. Despite the financial crisis, the automotive battery industry is in rapid growth. People pay more attention to hybrid vehicles and electric vehicles has led to battery innovation and market growth. With massive investment in research and development, Germany has to become a global leader in this market segment ready. Fraunhofer magazine said, the size of the domestic market in Germany has reached approximately $ 900 million broken down car battery, is expected in 2015, the market size will reach 100-150 billion. German automotive industry is accelerating this trend. Germany's leading automobile manufacturers are for a variety of battery-supported transportation solutions and work: the current plans to launch more than 10 models of hybrid and all-electric vehicles before 2010. Including Daimler (Daimler), BMW (BMW), Porsche (Porsche), Audi (Audi), VW (Volkswagen) and Opel (Opel) of the new car. Cooperation in this field for international partnerships and investment to bring a number of possibilities. For example, Daimler has decided to acquire California-based start-up Tesla Motors (Tesla Motors) 10% of the shares. The company will supply battery electric version of Daimler's Smart car. Electric version of the Smart car will be put into operation by the end of 2009. Daimler also with the German company Evonik strategic alliance to advance the development of lithium-ion batteries. General Assembly as a national electric mobility strategy (National Strategy Conference for Electric Mobility) part of buying a car battery, the German federal government recently established the goal is to make electric cars by 2020 in Germany on the street and plug-in hybrid vehicles reached 1,000,000, This will allow Germany to become the world's leading markets. To achieve this goal, from battery research to market perform, they plan to provide support for every step of the development of this process. www.weilipo.com Dazhou car battery | Wei Li Po batteries | car battery box is provided by Shenzhen Wei Lai Po Battery Limited.
