San Yang 12V38AH battery manufacturers agents puerile because my customers are friends, the company's credibility is invisible market, customer satisfaction is enduring market. Market philosophy: quality of today is tomorrow's market, the company spirit: when united, pragmatic, positive, progressive, good deeds a float voltage when the ambient temperature is 20 ~ 29 ℃, the average battery float voltage for single battery 2.23 volts, different temperature ranges according to the following criteria to determine the float voltage: Ambient Temperature (℃) float voltage (V) 0 ~ 9 2.29 10 ~ 19 2.26 20 ~ 29 2.23 30 ~ 39 2.20 Second, the battery charge voltage Shengyang The charge voltage can be set to 2.30 ~ 2.33V / only, specific requirements are as follows: one above the float voltage is lower than 2.18V / only, treatment is the next release of about 50% battery capacity, it is recommended in the manual are charging case charge 2 to 3 days, as is still recoverable, please contact us; when released more than 20% of rated capacity, to auto BC; 10 weeks are filled automatically once; charging time are automatically set to 15h. Third, the battery room requirements for battery installation at the place away from heat and easy to produce sparks, such as transformers, power switch or fuse, the safe distance of 0.5 meters. Should generally be kept at room temperature about 25 ℃. Battery should avoid direct sunlight, the installation environment free of organic solvents and corrosive gases. The cell surface and the electrode should be ready to clean up and make rust. Exchange should generally be set up independent battery room. Frequently check the battery reads as follows: terminal voltage; loose connections, heat, corrosion (should be cleared up, good corrosion protection); battery casing leaks and deformation; pole, safety around whether There mist escaping (frosting). Fourth, the initial use of the sealed battery prior to use without perform initial charging, but it should supplement charge. Supplementary charge should be limiting constant voltage charging method, the charging voltage shall be specified provisions, under normal circumstances (when the battery storage does not exceed six months, the ambient temperature is 25 ℃) supplementary charge voltage and charge time are as follows: single cell voltage (V ) Charging time (H) 2.23 2 ~ 3 天 2.30 ~ 2.33V 1 ~ 2 days at the temperature conditions when other charge time should be adjusted. If the ambient temperature between 10 ~ 20 ℃, the charging time should be doubled, if the ambient temperature is higher than 25 ℃, the charging time should be shortened. Colloid (GFMJ) 12 series Shengyang battery GFMJ-12V series VRLA gel batteries gel batteries introduction of Germany advanced production technology, using key raw materials imported from Europe, the use of European imports of key production equipment for the production. Flooded design, thick plate technology and unique gel electrolyte filling plus preparation process to ensure the battery life; design float life: at 25 ℃ ± 5 ℃ environment, the design life of 15 years. Under standard conditions, 25% DOD cycle life cycle 2950 times in communications, power, energy storage, UPS / EPS and other fields has been widely used. San Yang battery (colloidal) GFMJ-12V Series Applications: Widely used in communications equipment, medical equipment, security systems / instrumentation communications and power equipment, warning systems, UPS / EPS power converter, wired communication bureau (station), switching stations, Wireless Telecommunications Bureau (station), distributed base station, power, military and other kinds of private communications base stations, data transmission and video signal transmission system, wind, solar, and wind and solar power generation cycle of various applications. San Yang battery (colloidal) GFMJ-12V Series Features: ▲ high charge acceptance capability, saving time section; ▲ wide operating temperature range: -20 ℃ ~ 55 ℃; ▲ shelf life: After fully charged, at 25 ℃ ambient static Set stored for 2 years, remaining battery capacity is still more than 50%; ▲ ▲ anti deep discharge performance capacity range (C10): 33Ah-200Ah ▲ voltage: 12V ▲ design float life: at 25 ℃ ± 5 ℃ environment, 15 year; ▲ cycle life: under standard conditions, 25% DOD cycle 2950 times; ▲ self-discharge rate ≤2% / month; Good: 100% after discharge may continue to receive the load, and then around the recoverability of the original charge capacity
