The battery has the characteristics of no acid leakage, small resistance, vibration resistance, strong over discharge recovery ability, small self discharge, long service life and so on. Babyfeatures: equipment closely, no leakage, no pollution of acid; without a specific environment; without water, no need to add electrolyte, maintenance free; the connection is convenient, without the use of a particular direction; small resistance, high output power; low impedance design, low self discharge, capacity retention and storage time by more than 12 June at 20 DEG C; the C.C.D.S charge and discharge detection system, ensure product consistency; high strength engineering plastics as raw materials and high density superfine glass fiber separator, to ensure first-class quality of the battery; adapt to various temperature conditions (-15 C and 45 C); no free electrolyte, explosion-proof, small self discharge. Capacity type voltage reference weight size (V) (Ah) (Kg) length * width * height (mm) 6-GFM-71272.1115*65*946-GFM-1712175.5180*77*1676-GFM-38123811197*165*1756-GFM-65126518350*166*1756-GFM-1001210028407*173*210 performance and advantages: high safety and reliability. The safety valve automatically (VRLA), can prevent the gas is inhaled battery affects its performance, abnormal pressure and damage to the battery caused by gas can also prevent caused by charging. The battery has not closed in normal float under discharged electrolyte and acid mist. At the same time, the use of independent patent technology battery tray and battery matching, to ensure the use of batteries more secure. Very low self discharge rate by special Pb Ca alloy, impurity of separator, electrolyte and the production process are strictly controlled, at 20 OC, the battery does not need to add electricity can be used normally within 6 months. Silver plated copper core and special design. Using the conductive ability, ensure excellent electrical performance. This ability to adapt to the environment can be used in -20 to +50 DEG C under ambient temperature, suitable for desert and plateau climate. Special power supply used in riot control area. Very strong direction especially the diaphragm (AGM) solid electrolyte which does not flow adsorption. The battery can not leak without standing or lying, which ensures the normal use. This green pollution-free, no pollutants discharge and mute. The battery room needs no acid and corrosion protection measures, and can be equipped with electronic instruments and other equipment in one room. The measured voltage rated voltage of 2V4V6V8V10V12V > 2.1V > 4.2V > 6.3V > 8.4V > 10.5 > 12.6V battery charging: one cycle charge discharge mode of 1, if the use of equipment connected to the power source, charging saturation after leaving power from the battery charge and discharge cycle, choose the way it should be in this case. 2, when charging the maximum charge voltage should be limited to provide machine: the ambient temperature at 25 DEG C, 2V battery charge pressure is 2.35-2.45V; the charging voltage of 4V battery: 4.70-4.90V battery; charging voltage of 6V is 7.05-7.35V; the charging voltage of 8V battery: 9.40V-9.80V batteries for charging voltage of 10V; 11.75-12.25V; 12V battery charging voltage: 14.1-14.7V. The maximum charging current is less than the rated capacity value of 25%A. 3, when charging saturation, should immediately stop charging, otherwise the battery will be damaged or due to excessive charge will easily cause the battery drum. 4, charge and discharge, the battery can not be inverted. 5, the cycle life depends on the depth of each discharge, the greater the discharge depth, the less the number of batteries can be recycled. Two, float mode 1, if the device is connected with the power supply, and in a state of charge, just outside the power supply stops, powered by battery float charging mode should choose this case. 2, each battery battery float charging voltage setting range should be strictly controlled in the environment: 20 degrees, 2V battery float voltage is 2.25-2.30V, the maximum charge current is not greater than the rated capacity value of 25%A. 3, floating life is mainly affected by the floating voltage and ambient temperature, the higher the float voltage, battery life is short. Three, when discharge discharge, the battery terminal voltage is lower than the prescribed terminal voltage or multiple times of discharge, the over discharge will cause serious damage to the battery, lead to the battery life ahead of time termination.
