Hai Hai Chi Chi battery HZY12-12 price battery technology features: 1, rated working voltage: 2V, 6V, 12V 2, floating charge design life: 6V, 12V up to 12 years, 2V for more than 18 years. 3, the active substance: 99.9999% high purity electrolytic refined lead; 4, grid: lead, tin, calcium diverse corrosion resistant alloy; 5, nominal operating temperature: -20 ℃ ~ 50 ℃ 6, safe operating temperature: -40 ℃ ~ 60 ℃ 7, floating voltage (per cell): 2.23 ~ 2.30V (20 ℃ ~ 30 ℃) 8, charge voltage (per cell): 2.33 ~ 2.40V (20 ℃ ~ 30 ℃) 9, charging voltage temperature compensation coefficient: Every single -3mV ~ -5 mV / ℃ 10, gaseous compounds efficiency: not less than 99.9%. 11, the battery compartment cover material: high strength ABS engineering plastics, flame retardant UL94-HB rating of not less than the level. 12, the safety valve: the United States, "Benson" type Ventseal safe way exhaust valve, valve for high reliability aerospace grade EPDM rubber material, the body is a labyrinth structure, can play a dual role of filter acid, may be mist fully recovered, no mist escapes with ** overcharge capacity and resistance to overcharge life. Valve opening pressure: 10 ~ 30KPa; closing valve pressure: 8 ~ 10KPa 14, battery low valve opening pressure design, safety valves open automatically closed during use, ensure safe use. 15, the battery terminals: a resistance very small embedded copper terminals (terminal portion of lead in the battery pack), to avoid problems caused by thermal expansion of the terminal seal damage. The positive and negative terminals of the battery clearly marked for easy connection. 16, the battery terminal plate, the connection lines are used excellent conductive properties of copper, wiring board having an insulating jacket, has excellent corrosion resistance. US battery manufacturers have recognized the Asian companies have the lead, but said he was an advantage in accordance with customer needs "tailored" aspect. For example, A123, says that it is superior to competitors to master the technology to improve the energy efficiency of the battery, so you can supply the same capacity, but smaller battery pack. As of September 30, A123 from the ARRA subsidy in the amount of $ 249 million of the $ 123 million extracted. The company is also expanding through the supply chain to cut costs and improve battery design, plan within 15 months will cost cut in half. The company is also gradually expanding its Livonia, Michigan (Livonia) factory, in order to better enable production and demand docking. The company laid off at the end of 11 125 employees. A123 chief executive David Rubio (DavidVieau) said that the weak car battery demand is temporary problem. The company spokesman Dan 博尔加萨诺 (DanBorgasano) pointed out that car manufacturers plan to launch electric cars total of 116 models, significantly more than 50 models in 2010, while there are 36 automobile manufacturers are expected to produce next year will be at least one electric cars. As for the A123, the company said it has received 21 different types of battery contract vehicles, should be sufficient to ensure long-term operation of its existing production lines in seven years or even longer time inside. Meanwhile, A123 and other battery manufacturers have begun to turn their eyes to the market outside of the car, one of which is to provide backup power to the grid. Are believed to stabilize the grid energy storage for wind and solar-powered Douqi steep fall helpful. Rubio said that for the A123, the grid market means that nearly $ 2 billion in sales opportunities in the next three years. The third quarter of the company's power business sales revenue reached $ 20.1 million, compared with $ 6,000,000 during the same period last year more than tripled. Ultimately, the company expects sales grid market will account for 40% of its total sales revenue.
